scheme='http://www.blogger.com/atom/ns#' term='Teoricos'/><title type='text'>Lógica borrosa o difusa</title><content type='html'>Los circuitos termofluidodinámicos de convección natural están cobrando especial&lt;br /&gt;importancia en el diseño de reactores nucleares avanzados, debido a&lt;br /&gt;que la convección natural suministra un sistema eficiente de remoción de calor&lt;br /&gt;completamente pasivo. Sin embargo, bajo ciertas condiciones, estos sistemas&lt;br /&gt;presentan inestabilidades que pueden llegar a poner en riesgo la seguridad&lt;br /&gt;integral del reactor. Por otro lado, los controladores basados en lógica&lt;br /&gt;difusa proveen un entorno ideal para atacar problemas de control altamente&lt;br /&gt;no lineales. En este trabajo desarrollamos un software que implementa un&lt;br /&gt;control basado en lógica difusa, y estudiamos su aplicación a loops de convección&lt;br /&gt;natural caóticos. Analizamos numéricamente el control lingüístico del&lt;br /&gt;loop conocido como el problema de Welander en condiciones tales que, de no&lt;br /&gt;existir el control, el caudal de circulación presentaría un comportamiento inestable&lt;br /&gt;no periódico. Diseñamos también un controlador difuso a partir de un&lt;br /&gt;modelo matemático de Takagi y Sugeno para un loop de convección natural&lt;br /&gt;en geometría toroidal para estabilizar un comportamiento caótico de Lorenz.&lt;br /&gt;Finalmente, mostramos resultados experimentales obtenidos en un loop rectangular&lt;br /&gt;de convección natural.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Para una inteligencia que conociera en un momento dado todas&lt;br /&gt;las fuerzas que actúan en la naturaleza y la situación de los seres&lt;br /&gt;de que se compone [. . . ] nada le sería incierto y tanto el futuro&lt;br /&gt;como el pasado estarían presentes ante su vista.&lt;br /&gt;Pierre-Simon Laplace, 1812&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;La industria nuclear mundial deberá afrontar grandes desafíos en el mediano&lt;br /&gt;plazo, ya que las necesidades mundiales de energía eléctrica indican que la&lt;br /&gt;capacidad instalada deberá incrementarse notablemente. Más aún, consideraciones&lt;br /&gt;económicas y de impacto ambiental sugieren que sería conveniente que&lt;br /&gt;aumente la cuota de energía nuclear en el mercado eléctrico. Por otro lado, estudios&lt;br /&gt;de seguridad en el diseño conceptual de los reactores nucleares avanzados&lt;br /&gt;proponen utilizar sistemas de control y seguridad completamente pasivos&lt;br /&gt;con el objetivo de lograr un reactor inherentemente seguro.&lt;br /&gt;Existe entonces una tendencia a diseñar sistemas primarios de extracción&lt;br /&gt;de energía basados en convección natural, por lo que es necesario un estudio&lt;br /&gt;detallado de los fenómenos termofluidodinámicos asociados a este efecto. En&lt;br /&gt;particular, interesa analizar las condiciones bajo las cuales existen inestabilidades&lt;br /&gt;que puedan amenazar la seguridad del reactor.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;La cita con la que comenzamos este capítulo fue extraída del libro Teoría&lt;br /&gt;Analítica de las Probabilidades, escrito en un momento de la historia de la ciencia&lt;br /&gt;en el cual la mecánica empezaba a perfilarse como la disciplina que explicaría&lt;br /&gt;finalmente el completo y minucioso funcionamiento del universo, anhelo que&lt;br /&gt;el hombre sostiene desde la Grecia clásica. Si es que en verdad es posible encontrar&lt;br /&gt;una manera de describir el comportamiento tanto de los más grandes&lt;br /&gt;astros como de los más pequeños átomos a través de ecuaciones diferenciales,&lt;br /&gt;entonces nada nos sería incierto y tanto el futuro como el pasado estarían&lt;br /&gt;presentes ante nuestra vista. Lamentablemente para Laplace —y para todos&lt;br /&gt;nosotros— vinieron luego malas noticias.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Como bien cita Bruno Ruyú en la introducción de su tesis de maestría (2006),&lt;br /&gt;todo lo que nos rodea es complejo y no lineal. Y hoy sabemos que la mayoría&lt;br /&gt;de los sistemas no lineales presentan un comportamiento caótico, palabra que&lt;br /&gt;aparece en el título de este trabajo y que suele despertar cierto interés tanto&lt;br /&gt;en el ámbito académico como fuera de él. Luego de la publicación del trabajo&lt;br /&gt;de Edward Lorenz (1963) sobre flujo determinístico no periódico, revivió en la&lt;br /&gt;comunidad científica —ocupada hasta el momento con la mecánica cuántica—&lt;br /&gt;el interés por el estudio de los sistemas dinámicos que habían comenzado Henri&lt;br /&gt;Poincaré y Aleksandr Lyapunov —entre otros— en el siglo XIX.&lt;br /&gt;El análisis moderno de los sistemas dinámicos durante los últimos cuarenta&lt;br /&gt;años, soportado en parte por la disponibilidad de computadoras digitales,&lt;br /&gt;ha aportado una gran cantidad de resultados matemáticos realmente notables.&lt;br /&gt;El término caos —introducido por Li y Yorke (1975)— para referirse al comportamiento&lt;br /&gt;no periódico acotado y a la sensibilidad a condiciones iniciales ha&lt;br /&gt;dado lugar a la mediática teoría del caos, sobre la cual hablan los actores en las&lt;br /&gt;películas y en la que se basan los estudios sobre el poder destructivo de las&lt;br /&gt;mariposas.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Por otro lado, el título de este Proyecto Integrador contiene la idea de lógica&lt;br /&gt;difusa, concepto cuya concepción es también relativamente reciente y fue&lt;br /&gt;concebido originalmente por Lofti Zadeh en 1965. Se trata de una teoría matemática&lt;br /&gt;que extiende la lógica bivaluada tradicional y que —en cierto modo—&lt;br /&gt;propone acercarse a la forma de razonar de los seres humanos, que está muy&lt;br /&gt;lejos de ser una combinación lisa y llana de ceros y unos.&lt;br /&gt;La teoría de la lógica difusa ha probado tener aplicaciones en amplios espectros,&lt;br /&gt;por ejemplo en el campo de la inteligencia artificial y en la toma de&lt;br /&gt;decisiones asistida (Tarrazo, 2004). Y ciertamente una de las áreas que más se&lt;br /&gt;ha enriquecido con la lógica difusa es la teoría de control, pues resulta ésta una&lt;br /&gt;forma alternativa y a la vez poderosa de atacar cierta clase de problemas (Yen&lt;br /&gt;et al., 1995), muy difíciles de resolver utilizando técnicas tradicionales.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Existen muchas situaciones en las cuales el control automático de un sistema&lt;br /&gt;no resulta una tarea sencilla de ingeniería, cuando sin embargo un operador&lt;br /&gt;humano es capaz de lograr un objetivo de control. Por ejemplo, no es necesario&lt;br /&gt;pensar en vínculos holónomos, ciclos termodinámicos o funciones de&lt;br /&gt;transferencia para poder conducir un automóvil. La lógica difusa provee un&lt;br /&gt;entorno ideal para resolver problemas de forma más parecida al razonamiento&lt;br /&gt;humano que a la estricta matemática de los sistemas artificiales, ya que es posible&lt;br /&gt;diseñar un controlador aún sin tener un modelo matemático explícito de&lt;br /&gt;la planta.&lt;br /&gt;Uno de los problemas susceptibles de ser atacados con lógica difusa es ciertamente&lt;br /&gt;el control de sistemas caóticos. Y sucede además que los circuitos de&lt;br /&gt;convección natural presentan —bajo ciertas condiciones— un comportamien-&lt;br /&gt;to no periódico y con alta sensibilidad a condiciones iniciales1. En este trabajo&lt;br /&gt;intentamos entonces resolver el problema del control de loops de convección&lt;br /&gt;natural con herramientas de lógica difusa.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;En el capítulo 2 realizamos una introducción a la teoría de lógica difusa y&lt;br /&gt;sentamos la base matemática sobre la que basamos los controladores difusos&lt;br /&gt;que desarrollamos. El capítulo 3 comienza con una breve reseña de las ideas&lt;br /&gt;del control lineal y continúa presentando la estructura y el esquema de funcionamiento&lt;br /&gt;de un controlador lingüístico, para mejor observar las diferencias y&lt;br /&gt;ventajas del control difuso sobre el control tradicional. En el capítulo 4 ilustramos&lt;br /&gt;el proceso de diseño de un controlador difuso aplicado a tres problemas&lt;br /&gt;simples. Comenzamos con el estudio del control de un reactor modelado con&lt;br /&gt;cinética puntual, seguimos controlando un tanque mezclador de fluidos y terminamos&lt;br /&gt;con la aplicación de control lingüístico a un sistema físico sencillo&lt;br /&gt;pero que presenta comportamiento caótico.&lt;br /&gt;Introducimos el estudio de la convección natural en el capítulo 5 donde&lt;br /&gt;analizamos las características generales de los loops. Prestamos luego especial&lt;br /&gt;atención a un caso particular conocido como el problema de Welander (1967),&lt;br /&gt;al que aplicamos una acción de control lingüística para obtener un caudal de&lt;br /&gt;circulación estable en condiciones donde de otra forma existirían oscilaciones&lt;br /&gt;caóticas.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;El capítulo 6 describe un tipo de controladores difusos diferentes conocidos&lt;br /&gt;como controladores de Takagi-Sugeno, los cuales utilizan un modelo difuso&lt;br /&gt;para lograr una acción de control satisfactoria. Ilustramos su funcionamiento&lt;br /&gt;estabilizando un punto fijo inestable del sistema caótico de Lorenz. Pasamos&lt;br /&gt;luego al capítulo 7 donde estudiamos un loop de convección natural con una&lt;br /&gt;geometría toroidal. Allí mostramos que es posible describir razonablemente&lt;br /&gt;bien el problema termofluidodinámico con un sistema de tres ecuaciones diferenciales&lt;br /&gt;que resulta ser un caso particular del sistema de Lorenz, por lo que&lt;br /&gt;aplicamos las ideas de control de Takagi-Sugeno para controlar el loop.&lt;br /&gt;Finalmente, concluimos esta tesis presentando resultados experimentales&lt;br /&gt;obtenidos en un circuito convección natural. Hemos diseñado un sistema de&lt;br /&gt;adquisición de datos y construido un loop rectangular de sección transversal&lt;br /&gt;circular, cuyo comportamiento temporal estudiamos en el capítulo 8.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;El objetivo de este trabajo es estudiar los principios básicos de la aparición&lt;br /&gt;de las inestabilidades termofluidodinámicas que existen en los circuitos&lt;br /&gt;convección natural. De la misma manera, la investigación y el desarrollo de&lt;br /&gt;controladores basados en lógica difusa a partir de los principios matemáticos&lt;br /&gt;básicos nos provee una potente herramienta con la que atacar un amplio espectro&lt;br /&gt;de problemas no lineales.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;En particular, en este trabajo relacionamos&lt;br /&gt;estas dos líneas de investigación diferentes, proponiendo técnicas control difuso&lt;br /&gt;como una forma de atacar el problema de las oscilaciones en sistemas&lt;br /&gt;termohidráulicos de circulación natural.&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/36600673-5149504822994496564?l=gepraa.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/5149504822994496564'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/5149504822994496564'/><link rel='alternate' type='text/html' href='http://gepraa.blogspot.com/2009/11/logica-borrosa-o-difusa.html' title='Lógica borrosa o difusa'/><author><name>Gabriel Edgardo</name><uri>http://www.blogger.com/profile/15737621644756089532</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='29' src='http://2.bp.blogspot.com/_AVo6d3JS8vM/SJnpz2Bb2xI/AAAAAAAAAJo/Ehd9P9DGx7w/s1600-R/P1010116.JPG'/></author></entry><entry><id>tag:blogger.com,1999:blog-36600673.post-4002310009882873701</id><published>2008-12-27T21:04:00.005-02:00</published><updated>2010-03-20T08:37:28.831-03:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Conversación'/><category scheme='http://www.blogger.com/atom/ns#' term='COMENTARIOS'/><title type='text'>Recomendaciones en LinkedIn</title><content type='html'>&lt;a href="http://3.bp.blogspot.com/_AVo6d3JS8vM/SW92xjOfVsI/AAAAAAAAATE/Nm34swynBN8/s1600-h/tarjeta.jpg"&gt;&lt;img style="WIDTH: 400px;

Estos tres niveles son los que habitualmente se utilizan para diseñar y para describir un automatismo.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="color:#ff0000;"&gt;GRAFCET de nivel 1: Descripción funcional&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;En el primer nivel interesa una descripción global (normalmente poco detallada) del automatismo que permita comprender rápidamente su función. Es el tipo de descripción que haríamos para explicar lo que queremos que haga la máquina a la persona que la ha de diseñar o el que utilizaríamos para justificar, a las personas con poder de decisión en la empresa, la necesidad de esta máquina.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;a href="http://2.bp.blogspot.com/_AVo6d3JS8vM/SLA3pjLNb1I/AAAAAAAAALY/HKnKXWOVSxk/s1600-h/grfc.bmp"&gt;&lt;img id="BLOGGER_PHOTO_ID_5237747553588309842" style="CURSOR: hand" alt="" src="http://2.bp.blogspot.com/_AVo6d3JS8vM/SLA3pjLNb1I/AAAAAAAAALY/HKnKXWOVSxk/s400/grfc.bmp" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Este GRAFCET no debe contener ninguna referencia a las tecnologías utilizadas; es decir no se especifica cómo hacemos avanzar la pieza (cilindro neumático, motor y cadena, cinta transportadora, etc.), ni cómo detectamos su posición (fin de carrera, detector capacitivo, detector fotoeléctrico, etc.), ni tan solo el tipo de automatismo utilizado (autómata programable, neumática, ordenador industrial, etc.).&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="color:#ff0000;"&gt;GRAFCET de nivel 2: Descripción tecnológica.&lt;br /&gt;&lt;/span&gt;&lt;/strong&gt;En este nivel se hace una descripción a nivel tecnológico y operativo del automatismo. Quedan perfectamente definidas las diferentes tecnologías utilizadas para cada función. El GRAFCET describe las tareas que han de realizar los elementos escogidos. En este nivel completamos la estructura de la máquina y nos falta el automatismo que la controla.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;a href="http://1.bp.blogspot.com/_AVo6d3JS8vM/SLA4GXFFl6I/AAAAAAAAALg/6RKr1uCXXK4/s1600-h/grfc.bmp"&gt;&lt;img id="BLOGGER_PHOTO_ID_5237748048557610914" style="CURSOR: hand" alt="" src="http://1.bp.blogspot.com/_AVo6d3JS8vM/SLA4GXFFl6I/AAAAAAAAALg/6RKr1uCXXK4/s400/grfc.bmp" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="color:#ff0000;"&gt;GRAFCET de nivel 3: Descripción operativa.&lt;br /&gt;&lt;/span&gt;&lt;/strong&gt;En este nivel se implementa el automatismo. El GRAFCET definirá la secuencia de actuaciones que realizará este automatismo. En el caso de que se trate, por ejemplo, de un autómata programable, definirá la evolución del automatismo y la activación de las salidas en función de la evolución de las entradas.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;a href="http://4.bp.blogspot.com/_AVo6d3JS8vM/SLA4gbDA4wI/AAAAAAAAALo/9L0G6kVGIVo/s1600-h/grfc.bmp"&gt;&lt;img id="BLOGGER_PHOTO_ID_5237748496299254530" style="CURSOR: hand" alt="" src="http://4.bp.blogspot.com/_AVo6d3JS8vM/SLA4gbDA4wI/AAAAAAAAALo/9L0G6kVGIVo/s400/grfc.bmp" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;El siguiente link nos redirige a un siti0 interesante donde reside un curso básico acerca de la teoría del GRAFCET y presentación, descripción y utilización de la guía GEMMA:&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;a href="http://edison.upc.es/curs/grafcet/"&gt;http://edison.upc.es/curs/grafcet/&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="font-size:130%;color:#009900;"&gt;Metodología GRAFCET.&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="font-size:130%;color:#009900;"&gt;&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;span style="font-size:130%;color:#009900;"&gt;&lt;br /&gt;&lt;span style="font-size:100%;color:#000000;"&gt;METODOLOGÍA GRAFCET: CONCEPTOS BÁSICOS&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:100%;color:#000000;"&gt;El Grafcet se compone de un conjunto de:&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:100%;color:#000000;"&gt;· Etapas o Estados a las que van asociadas acciones.&lt;br /&gt;· Transiciones a las que van asociadas receptividades.&lt;br /&gt;· Uniones Orientadas que unen las etapas a las transiciones y las&lt;br /&gt;transiciones a las etapas.&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:100%;color:#000000;"&gt;&lt;/span&gt;&lt;br /&gt;&lt;span style="color:#000000;"&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;Etapas&lt;br /&gt;Una etapa se caracteriza por un comportamiento invariable en una parte o en&lt;br /&gt;la totalidad de la parte de mando.&lt;br /&gt;En un momento determinado, y según sea la evolución del sistema:&lt;br /&gt;· Una etapa puede estar activa o inactiva.&lt;br /&gt;· El conjunto de las etapas activas definen la situación de la parte de mando.&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;Las etapas se representan por un cuadrado con un número en su parte superior&lt;br /&gt;como identificación. La entrada y salida de una etapa aparece en la parte superior e&lt;br /&gt;inferior, respectivamente, de cada símbolo. El conjunto formado por el cuadrado y la&lt;br /&gt;extensión de las entradas y salidas constituye el símbolo completo de la etapa...&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;Cuando es necesario determinar la situación del Grafcet en un momento&lt;br /&gt;determinado, es muy cómodo identificar todas las etapas activas en ese momento,&lt;br /&gt;mediante un punto en la parte inferior de los símbolos de las etapas activas...&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;Cuando varias transiciones van unidas a una misma etapa, las uniones&lt;br /&gt;orientadas correspondientes se reagrupan antes o después de la etapa...&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;&lt;strong&gt;&lt;span style="font-size:130%;color:#009900;"&gt;Acciones asociadas a las etapas.&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;Las acciones están descritas, literal o simbólicamente, en el interior de uno o&lt;br /&gt;varios rectángulos unidos al símbolo de la etapa a la que van asociados.&lt;br /&gt;Tanto las acciones asociadas a las etapas como las receptividades asociadas a&lt;br /&gt;las transiciones se pueden describir a dos niveles:&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;· Nivel 1: no tienen en cuenta los elementos tecnológicos que implementan&lt;br /&gt;el órgano operativo y sólo se atienden a las especificaciones de tipo&lt;br /&gt;funcional. Se trata de describir las funciones del sistema.&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Nivel 2: se especifican los aspectos tecnológicos del órgano operativo y de&lt;br /&gt;lo que le rodea y de las especificaciones operacionales del órgano de&lt;br /&gt;control.&lt;br /&gt;&lt;br /&gt;Cuando las acciones están descritas en forma simbólica, debe haber una tabla&lt;br /&gt;con la relación entre cada símbolo utilizado y la acción a ejecutar. Para el ejemplo&lt;br /&gt;anterior debería existir algo como:&lt;br /&gt;AC1: Avance del Carro 1&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="color:#009900;"&gt;Transición.&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;br /&gt;Una transición indica la posibilidad de evolución entre etapas. Esta evolución&lt;br /&gt;se consuma al producirse el franqueo de la transición. El franqueo de una transición&lt;br /&gt;provoca el paso en la parte de mando de una situación a otra situación.&lt;br /&gt;Una transición puede estar validada o no validada. Se dice que está&lt;br /&gt;validada cuando todas las etapas inmediatamente unidas a esta transición están&lt;br /&gt;activas.&lt;br /&gt;Una transición entre dos etapas se representa mediante una línea&lt;br /&gt;perpendicular a las uniones orientadas, también puede llevar una línea paralela a las&lt;br /&gt;uniones orientadas. Para facilitar la comprensión del Grafcet cada transición puede ir&lt;br /&gt;numerada a la izquierda de la línea perpendicular.&lt;br /&gt;Ilustración&lt;br /&gt;&lt;/span&gt;&lt;span style="color:#000000;"&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="color:#009900;"&gt;Receptividad asociada a la transición.&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;A cada transición va asociada una proposición lógica llamada receptividad&lt;br /&gt;que puede evaluada a verdadero o falso. Entre todas las informaciones disponibles en&lt;br /&gt;un momento determinado, la receptividad agrupa solamente aquellas que son&lt;br /&gt;necesarias para el franqueo del transición. La receptividad es función de&lt;br /&gt;informaciones externas (entradas) o internas (estado de contadores, temporizadores,&lt;br /&gt;estados activos o inactivos de otras etapas).&lt;br /&gt;Las entradas de la parte de mando corresponden a las informaciones externas&lt;br /&gt;provenientes de la parte operativa, de consignas dadas por el operador, o de&lt;br /&gt;informaciones de otros sistemas.&lt;br /&gt;La receptividad va escrita literal o simbólicamente, preferentemente a la&lt;br /&gt;derecha del símbolo de la transición.&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:100%;"&gt;&lt;br /&gt;Cuando la receptividad está escrita en forma simbólica, una tabla debe dar la&lt;br /&gt;correspondencia entre cada símbolo utilizado y la información correspondiente. En el&lt;br /&gt;ejemplo anterior&lt;br /&gt;Aci: Señal Arranque&lt;br /&gt;Cuando no hay condición asociada a una transición, se dice que la&lt;br /&gt;receptividad es verdadera siempre y se escribe =1.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Uniones orientadas.&lt;br /&gt;&lt;br /&gt;Las uniones orientadas unen las etapas a las transiciones y las transiciones a&lt;br /&gt;las etapas. Señalan el camino de las evoluciones.&lt;br /&gt;Las uniones orientadas se representan mediante líneas horizontales o&lt;br /&gt;verticales. Las líneas oblicuas pueden ser empleadas excepcionalmente siempre que&lt;br /&gt;añadan claridad al diagrama. Por convenio, el sentido de las evoluciones en un&lt;br /&gt;Grafcet es de arriba hacia abajo.&lt;br /&gt;La flechas se utilizan para señalar la orientación de las uniones:&lt;br /&gt;· cuando no se respeta el convenio.&lt;br /&gt;· en casos especiales, siempre que su presencia aporte claridad y facilite la&lt;br /&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;&lt;/span&gt;&lt;span style="font-size:100%;"&gt;&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style="font-size:100%;color:#000000;"&gt;Reglas de Evolución&lt;br /&gt;&lt;br /&gt;Situación Inicial&lt;br /&gt;&lt;br /&gt;La situación inicial del Grafcet caracteriza el comportamiento inicial de la&lt;br /&gt;parte de mando en relación a la parte operativa, y corresponde a las etapas activas al&lt;br /&gt;comienzo del funcionamiento. Si esta situación es siempre la misma, caso de los&lt;br /&gt;automatismos cíclicos, estará caracterizada por las etapas iniciales. Este caso&lt;br /&gt;corresponde a un comportamiento de reposo.&lt;br /&gt;En el caso de automatismos no cíclicos, la situación de partida depende del&lt;br /&gt;estado del proceso en el momento de la puesta en marcha de la parte de mando. La&lt;br /&gt;forma de establecer la situación inicial debe ser definida en el Grafcet o en&lt;br /&gt;documentación adjunta.&lt;br /&gt;&lt;br /&gt;Franqueo de una Transición&lt;br /&gt;La evolución de la situación del Grafcet correspondiente al franqueo de una&lt;br /&gt;transición no puede producirse más que:&lt;br /&gt;· cuando esta transición está validada y&lt;br /&gt;· cuando la receptividad asociada a esa transición es cierta.&lt;br /&gt;Cuando estas dos condiciones se cumplen, la transición es franqueable y&lt;br /&gt;entonces es franqueada obligatoriamente.&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size:130%;color:#009900;"&gt;&lt;span style="font-size:100%;color:#000000;"&gt;Evolución de las Etapas activas&lt;br /&gt;El franqueo de una transición trae como consecuencia la activación&lt;br /&gt;simultánea de todas las etapas inmediatamente posteriores y la desactivación de todas&lt;br /&gt;las etapas inmediatamente anteriores.&lt;/span&gt;&lt;span style="font-size:100%;color:#000000;"&gt;&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;Elementos de programación&lt;br /&gt;&lt;br /&gt;Para programar un autómata en GRAFCET es necesario conocer cada uno de los elementos propios de que consta.

RS-232 defines both the physical and electrical characteristics of the interface. RS-232 is practically identical to ITU V.24 (signal description and names) and V.28 (electrical). RS232 is an Active LOW voltage driven interface and operates at +12V to -12V where:&lt;br /&gt;Signal = 0 (LOW) &gt; +3.0V&lt;br /&gt;Signal = 1 (HIGH) &lt; -3.0V Notes: 1. Signal voltages in the range &gt;-3.0V to +3.0V is regarded as the 'dead area' and allows for absorption of noise. For more &lt;/span&gt;&lt;a href="http://www.zytrax.com/tech/layer_1/cables/heavy.htm"&gt;&lt;span style="color:#000000;"&gt;on the use of signals and other heavy stuff&lt;/span&gt;&lt;/a&gt;&lt;span style="color:#000000;"&gt;.&lt;br /&gt;2. The power level on RS232 pins is defined by TIA in terms of short circuit protection to be 100mA. Most RS232 drivers will provide lower short circuit protection (especially for laptops). A max of 50mA PER PIN may be available but the data sheet for the specific interface/chip should be consulted before commiting to externally powered designs.&lt;br /&gt;3. We received an email recently pointing out some issues with NULL modem cables. The pinouts shown below will gnerally work. However there are many permutations of signal sets that can be used by either end of a connection and they may not be SYMMETRIC. One end may expect something (a signal) that the other end cannot generate. This typically happens with CTS/RTS (and perhaps DCD) and DTR/DSR. If you suspect this is the case then unfortunately you need to UNDERSTAND the interface and may have to SPOOF certain signals. Our &lt;/span&gt;&lt;a href="http://www.zytrax.com/tech/layer_1/cables/heavy.htm"&gt;&lt;span style="color:#000000;"&gt;signal primer&lt;/span&gt;&lt;/a&gt;&lt;span style="color:#000000;"&gt; page may help you. Finally if you are having serious problems, splash out on a light box or some other device that will show you which signals are being activated.&lt;br /&gt;4. Serial communications equipment may either a &lt;/span&gt;&lt;a href="http://www.zytrax.com/tech/layer_1/cables/tech_rs232.htm#dte#dte"&gt;&lt;span style="color:#000000;"&gt;DTE&lt;/span&gt;&lt;/a&gt;&lt;span style="color:#000000;"&gt; (Data Terminal Equipment - a terminal or PC) or a &lt;/span&gt;&lt;a href="http://www.zytrax.com/tech/layer_1/cables/tech_rs232.htm#dte#dte"&gt;&lt;span style="color:#000000;"&gt;DCE&lt;/span&gt;&lt;/a&gt;&lt;span style="color:#000000;"&gt; (Data communications Equipment - for example, a modem) and have a direction depending on the type. All the diagrams below define the interface from the DTE perspective.&lt;br /&gt;5. The terms Data Carrier Detect (DCD) and Received Line Signal Detect (RLSD) are one and the same. We use DCD throughout 'cos we think it's more common.&lt;br /&gt;6. Like most folks we use the term DB9 which is widely - but erroneously - used to describe a 9-pin serial connector. We got an email pointing out the error of our ways. So, if you want to amaze your friends over the dinner table you can &lt;/span&gt;&lt;a href="http://www.zytrax.com/tech/layer_1/cables/tech_rs232.htm#dbx#dbx"&gt;&lt;span style="color:#000000;"&gt;read more here and use the technically correct terms in the future&lt;/span&gt;&lt;/a&gt;&lt;span style="color:#000000;"&gt;. While we get away with it most of the time (with common or garden PCs), sometimes it is essential to know EXACTLY what connector type you are talking about.&lt;br /&gt;7. RS-232-E is normally defined to be used with a DB25 connector, but does have a 26 pin (a much smaller connector) alternate . We suggest that if you come across one of these that you do the decent thing - use an expletive. Alternatively, with your luck, you could consider buying a lottery ticket.&lt;br /&gt;8. We have received a number of emails recently asking how to wire DB9's using cat5(e) cable. We guess there is a lot of LAN cable lying around these days so folks naturally want to use it. We have added a &lt;/span&gt;&lt;a href="http://www.zytrax.com/tech/layer_1/cables/tech_rs232.htm#null-cat5#null-cat5"&gt;&lt;span style="color:#000000;"&gt;null modem only section&lt;/span&gt;&lt;/a&gt;&lt;span style="color:#000000;"&gt; to cover this wiring. There is absolutely no standard to cover this form of wiring. This section is simply offered as one of many possible ways to do it.&lt;br /&gt;9. We got an email asking about TTY 20ma current loop interfaces. This was the old method used to connect teletype devices and uses current (normally 20ma but sometimes 60ma) to indicate mark and space. A TTY system CANNOT be connected to RS-232 (which is a voltage driven interface) and has no standard. You will need to get the manufacturer's specifications and start reading!&lt;/span&gt;&lt;br /&gt;&lt;/div&gt;&lt;br /&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt; &lt;/div&gt;&lt;div&gt;&lt;div&gt;&lt;br /&gt;&lt;div align="left"&gt;DTE (PC) and DCE (Modem)&lt;br /&gt;In serial communications the terminal end (PC) is called the Data Terminal Equipment (DTE) and the modem is called the Data Communications Equipment (DCE) as shown in the diagram below.&lt;/div&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;p&gt;&lt;img id="BLOGGER_PHOTO_ID_5229753658024252402" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="http://1.bp.blogspot.com/_AVo6d3JS8vM/SJPRPllV0_I/AAAAAAAAAHY/x1U07wZfpWw/s400/modem.bmp" border="0" /&gt;&lt;br /&gt;Serial Communications with a modem&lt;br /&gt;RS-232 signals have a direction (in or out) depending on whether they are with respect to a DTE or a DCE. In all the pinout diagrams below the signal direction is with respect to the DTE (PC).&lt;br /&gt;&lt;br /&gt;&lt;/p&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;p&gt;NULL Modem Connections&lt;br /&gt;When PCs are connected back-to-back each is acting as a DTE (there is no DCE in this case) and consequently certain signals have to be looped in the connection to satisfy any input signal requirement. This is called a NULL (no) modem configuration. For example, when the DTE raises Request to Send (RTS) it expects Clear to Send (CTS) from the DCE. Since there is no DCE to raise CTS, the outgoing RTS signal is looped in the NULL modem cable to the incoming CTS satisfy the DTE's need for this signal. This is shown in the diagram below.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;/p&gt;&lt;br /&gt;&lt;p&gt;&lt;img id="BLOGGER_PHOTO_ID_5229754390630797826" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="http://4.bp.blogspot.com/_AVo6d3JS8vM/SJPR6OwWkgI/AAAAAAAAAHg/MQCyd1cg0d4/s400/modem.bmp" border="0" /&gt;&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;DB9 and DB25 Male and Female Pin Numbering&lt;/strong&gt;&lt;br /&gt;&lt;/p&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;p&gt;These diagrams show the male (grey background) and female (black background) pin numbering for DB9 and DB25 sub-miniature connectors.

This means it is impossible to differentiate between a incoming ring signal and when the modem has finally connected and synched up. With local (null modem connections) or if the modem is run in auto-answer mode this is not normally a problem. If used with a modem and the DTE (the computer end) wants to control the connection the problem is more real. DSR would normally indicate the 'connected and synched-up' state following DTR from the DTE. DCD will indicate that a carrier has been received but does not indicate synchronization of both ends. In most cases however CTS (Clear To Send) in response to RTS (Request To Send) will not normally be returned until an end-to-end connection is available.&lt;br /&gt;&lt;/p&gt;&lt;br /&gt;&lt;br /&gt;&lt;p&gt;&lt;/p&gt;&lt;img id="BLOGGER_PHOTO_ID_5231169301854776674" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="http://1.bp.blogspot.com/_AVo6d3JS8vM/SJjYw5z7bWI/AAAAAAAAAIw/D9uGXhCNDjU/s400/Nuevo+Imagen+de+mapa+de+bits.bmp" border="0" /&gt;&lt;br /&gt;&lt;br /&gt;&lt;p align="center"&gt;RJ45 Male Connector Pin Numbering&lt;/p&gt;&lt;br /&gt;&lt;br /&gt;&lt;p&gt;RS232 DB25 NULL Modem Pinout&lt;br /&gt;Use when connecting two systems (e.g. PCs) via their DB25 interfaces without a modem (i.e. back-to-back).

Data is sent and received on the same RS232 connector - which may be either DB9 or DB25. The test normally consists of using some program to transmit data. The program then checks to ensure exactly the same data was received. If this test is performed using two systems and it fails the question is - which end has the problem? Loopback testing gives you a binary result - it works, in which case thes end under test is good, or it does not, in which case the end under test is broken. Pinouts are shown for both DB9 and DB25. The loopback is normally constructed in the DB shell or using a diagnostic light-box.&lt;br /&gt;&lt;/div&gt;&lt;br /&gt;&lt;p align="left"&gt;&lt;br /&gt;DB9 Loopback&lt;/p&gt;&lt;br /&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;br /&gt;&lt;p align="left"&gt;&lt;a href="http://2.bp.blogspot.com/_AVo6d3JS8vM/SJ8JjeKj1bI/AAAAAAAAAKA/ymfz40kHZfY/s1600-h/Nuevo+Imagen+de+mapa+de+bits.bmp"&gt;&lt;img id="BLOGGER_PHOTO_ID_5232911797025232306" style="CURSOR: hand" alt="" src="http://2.bp.blogspot.com/_AVo6d3JS8vM/SJ8JjeKj1bI/AAAAAAAAAKA/ymfz40kHZfY/s400/Nuevo+Imagen+de+mapa+de+bits.bmp" border="0" /&gt;&lt;/a&gt;&lt;/p&gt;&lt;br /&gt;&lt;br /&gt;&lt;p align="left"&gt;NOTE:&lt;br /&gt;1. We show 4 (DTR) being looped to 6 (DSR), 1 (DCD) and 9 (RI).

For the sake of simplicity this loopback will only work for the primary channel. Full DB25 interfaces allow a secondary channel. If a complete interface loopback is required you will need to add pins &lt;a href="http://www.zytrax.com/tech/layer_1/cables/tech_rs232.htm#db25#db25"&gt;12, 13, 14, 16, 19, 24&lt;/a&gt;.&lt;br /&gt;2. By looping the primary channel clocks (15 and 17) both synchronous and asynchronous capabilities can be tested. If only asynchronous tests are being performed omit this, and the pin 23 loopback&lt;br /&gt;3. We show 20 (DTR) being looped to 6 (DSR), 8 (DCD) and 22 (RI). RI (22) is included because we understand that certain test programs use this to ensure a more complete test of the interface signal set.&lt;br /&gt;&lt;a href="http://www.zytrax.com/tech/layer_1/cables/tech_rs232.htm#contents#contents"&gt;&lt;/a&gt;&lt;br /&gt;&lt;a name="null-cat5"&gt;&lt;/a&gt;&lt;/p&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;br /&gt;&lt;p align="left"&gt;RS232 DB9 NULL Modem Pinout on CAT5&lt;br /&gt;This is in response to a number of recent emails asking how to wire both ends of a DB9 connection using cat5(e) cable. This must not be confused with &lt;a href="http://www.zytrax.com/tech/layer_1/cables/tech_rs232.htm#rj45#rj45"&gt;DB9 to RJ45 (RS232D)&lt;/a&gt;. We have shown a null modem (back-to-back PCs) only configuration. And if you want to use cat5(e) with a real modem (a DB25 connector)? Our advice - don't.&lt;br /&gt;Warning:. There is, as far as we know, no standard to cover the use of cat5(e) (8 conductor) wiring when used with two DB9 connectors. Any such wiring scheme is therefore non-standard - that includes the wiring scheme below. Specifically this means that both ends of the cable must be wired in the same way and that no assumptions can be made about how the other end is wired. You will have to manually inspect both ends of the connection. Damage can result from mis-matched wiring.&lt;br /&gt;A DB9 clearly has 9 connections and a cat5(e) cable has 8 conductors. &lt;a href="http://www.zytrax.com/tech/layer_1/cables/rj45"&gt;RS232D&lt;/a&gt; has chosen to use Pin 1 as a multi-function pin (DSR/RI) to provide maximum flexibility with modems - in particular it allows for DCD which is a meaningful signal from a modem but not we suggest from a peer PC. We have chosen to use a minor variation on the normal DB9 Null modem pinout above - specifically we have allowed for RI which could be used from a peer PC to commence a transmission sequence. The colors used are unimportant but the suggested configuration is one way to provide the shortest use of the adjacent (twisted) pairs.&lt;br /&gt;If this pinout does not work for you then you could try our &lt;a href="http://www.zytrax.com/tech/layer_1/cables/heavy.htm"&gt;Signal/pin primer&lt;/a&gt; because you may need to SPOOF connections.&lt;/p&gt;&lt;br /&gt;&lt;br /&gt;&lt;p align="center"&gt;&lt;a href="http://3.bp.blogspot.com/_AVo6d3JS8vM/SLAaCYa3jtI/AAAAAAAAAKQ/XaI-l9HDVNw/s1600-h/Nuevo+Imagen+de+mapa+de+bits.bmp"&gt;&lt;img id="BLOGGER_PHOTO_ID_5237714994849091282" style="CURSOR: hand" alt="" src="http://3.bp.blogspot.com/_AVo6d3JS8vM/SLAaCYa3jtI/AAAAAAAAAKQ/XaI-l9HDVNw/s400/Nuevo+Imagen+de+mapa+de+bits.bmp" border="0" /&gt;&lt;/a&gt;&lt;/p&gt;&lt;br /&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;br /&gt;&lt;p align="center"&gt;&lt;a href="http://1.bp.blogspot.com/_AVo6d3JS8vM/SLAahTJhPWI/AAAAAAAAAKY/yLt0Y8I5zd8/s1600-h/Nuevo+Imagen+de+mapa+de+bits.bmp"&gt;&lt;img id="BLOGGER_PHOTO_ID_5237715526010092898" style="CURSOR: hand" alt="" src="http://1.bp.blogspot.com/_AVo6d3JS8vM/SLAahTJhPWI/AAAAAAAAAKY/yLt0Y8I5zd8/s400/Nuevo+Imagen+de+mapa+de+bits.bmp" border="0" /&gt;&lt;/a&gt;&lt;/p&gt;&lt;br /&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;br /&gt;&lt;p align="center"&gt;DB9: View - looking into male connector&lt;/p&gt;&lt;br /&gt;&lt;p align="left"&gt;NOTE:&lt;br /&gt;1.

By using a DB25 connector RS-530 is now frequently used to replace many older standards which defined hideously huge connectors such &lt;a href="http://www.zytrax.com/tech/layer_1/cables/tech_rs232.htm#v35#v35"&gt;V.35.&lt;/a&gt; (used a whopping 35 pin connector) and RS-449 (used a pretty serious 37 pin connector).&lt;br /&gt;&lt;a name="v35"&gt;&lt;/a&gt;V.35 on DB25 (RS-530-A)&lt;br /&gt;The original V.35 specification defined use of &lt;a href="http://www.zytrax.com/tech/layer_1/cables/heavy.htm#balanced"&gt;balanced signals&lt;/a&gt; over a huge 35 pin connector. V.35 has been obsolete for years (replaced with V.10 and V.11) though the term is still frequently used. Most modern systems that call themselves V.35 use a DB25 connector which has more modest dimensions. The A (+) and B (-) below refer to each signal pair used in &lt;a href="http://www.zytrax.com/tech/layer_1/cables/heavy.htm#balanced"&gt;balanced serial interfaces&lt;/a&gt;. When used with RS-423 (unbalanced) the B (-) are tied to a common ground. Signals marked U under Bal/Ubal are not balanced since they typically change very infrequently (for example once per session) and therefore do not affect TX/RX performance sensitivity - hence speed. BEWARE: RS-530 (without the A suffix) is an earlier standard and is wired differently. This is the 530-A pinout spec.&lt;br /&gt;&lt;a href="http://www.zytrax.com/tech/layer_1/cables/heavy.htm"&gt;Signal/pin primer&lt;/a&gt;&lt;/p&gt;&lt;br /&gt;&lt;p align="center"&gt;&lt;a href="http://4.bp.blogspot.com/_AVo6d3JS8vM/SLAejKU5q-I/AAAAAAAAALA/tkS9XUqT0I0/s1600-h/Nuevo+Imagen+de+mapa+de+bits.bmp"&gt;&lt;img id="BLOGGER_PHOTO_ID_5237719956048161762" style="CURSOR: hand" alt="" src="http://4.bp.blogspot.com/_AVo6d3JS8vM/SLAejKU5q-I/AAAAAAAAALA/tkS9XUqT0I0/s400/Nuevo+Imagen+de+mapa+de+bits.bmp" border="0" /&gt;&lt;/a&gt;&lt;/p&gt;&lt;br /&gt;&lt;p align="left"&gt;NOTES:&lt;br /&gt;Leave any pins not specified above unconnected.&lt;br /&gt;In balanced mode signals with the same name are the paired set, for example, pins 2 and 14 are both named BA and form the Transmit Data pair.

The S7 protocol is an  application layer protocol which implements functions for exchanging data  between Simatic S7 series PLCs and other devices that supports the S7 protocol -  e.g. PCs.&lt;br /&gt;&lt;br /&gt;The S7 protocol can be running on either a standard PROFIBUS  network or on a MPI network.&lt;br /&gt;&lt;br /&gt;MPI network is used for connecting to the  CPU port directly on S7 PLC systems. This means that no extra CP board has to be  installed in the PLC. Some network parameters e.g. the baudrate is restricted on  MPI type networks.&lt;br /&gt;&lt;br /&gt;Running the S7 protocol on a PROFIBUS network  requires the S7 PLC systems to have a separate CP board installed and offers the  full flexibility of a PROFIBUS network e.g. mixing electrical and optical  networks etc. Applicable CP boards are e.g. CP443-5 for Simatic S7/400 series  and CP343-5 for Simatic S7/300 series. Other CP boards supporting S7 functions  might also be applied.&lt;br /&gt;&lt;br /&gt;The S7 protocol can also be used with Siemens  Industrial Ethernet (Siemens IE). Both ISO and TCP/IP are supported as transport  protocols. Siemens IE is used in the S7/300 and S7/400 series. Applicable CP  boards are e.g. CP443-1 or CP443-1 IT for the S7/400 and CP343-1 for the S7/300. &lt;br /&gt;&lt;br /&gt;Connecting a PC to either MPI or PROFIBUS network requires an interface  board and some board driver software from Siemens to be installed in the PC.  Connecting a PC to Siemens Industrial Ethernet requires either a standard  ethernet interface board or one of the "state of the art" ethernet boards  available from Siemens. Applicable interface boards are listed below. &lt;br /&gt;&lt;br /&gt;The IGSS32 system polls the PLC equipment cyclically according to one of  four user-defined time intervals. The time intervals are configurable from 100  milliseconds to 999 seconds. The system automatically groups process data in  data blocks - thus fully exploiting the the communication link in relation to  the present configuration.&lt;br /&gt;&lt;br /&gt;It is possible to apply event-oriented  communication. Then the PLC equipment has control over when and which data to  send to the IGSS32 system. In this way the use of available communication  bandwidth can be optimised. The S7 functions BSEND and BRECV is used for this  purpose. &lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/36600673-3108594211056159364?l=gepraa.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://gepraa.blogspot.com/feeds/3108594211056159364/comments/default' title='Comentarios de la entrada'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=36600673&amp;postID=3108594211056159364' title='0 Comentarios'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/3108594211056159364'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/3108594211056159364'/><link rel='alternate' type='text/html' href='http://gepraa.blogspot.com/2008/05/siemens-profibus-mpi-protocolo-s7.html' title='Siemens PROFIBUS / MPI Protocolo S7 &amp; Ethernet'/><author><name>Gabriel Edgardo</name><uri>http://www.blogger.com/profile/15737621644756089532</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='29' src='http://2.bp.blogspot.com/_AVo6d3JS8vM/SJnpz2Bb2xI/AAAAAAAAAJo/Ehd9P9DGx7w/s1600-R/P1010116.JPG'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-36600673.post-5958633279902104367</id><published>2008-05-24T23:32:00.002-03:00</published><updated>2008-05-24T23:37:23.523-03:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Comunicaciones'/><title type='text'>ModBus Plus</title><content type='html'>&lt;div&gt;&lt;span class="Apple-style-span" style="font-size: x-large;"&gt;&lt;span class="Apple-style-span" style="color: rgb(255, 0, 0);"&gt;Modbus&lt;/span&gt;&lt;/span&gt; es un protocolo de comunicaciones situado en el nivel 7 del Modelo OSI, basado en la arquitectura maestro/esclavo o cliente/servidor, diseñado en 1979 por Modicon para su gama de controladores lógicos programables (PLCs). Convertido en un protocolo de comunicaciones estándar de facto en la industria es el que goza de mayor disponibilidad para la conexión de dispositivos electrónicos industriales. &lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Las razones por las cuales el uso de Modbus es superior a otros protocolos de comunicaciones son:&lt;/div&gt;&lt;div&gt;es público&lt;/div&gt;&lt;div&gt;su implementación es fácil y requiere poco desarrollo&lt;/div&gt;&lt;div&gt;maneja bloques de datos sin suponer restricciones&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Modbus permite el control de una red de dispositivos, por ejemplo un sistema de medida de temperatura y humedad, y comunicar los resultados a un ordenador. Modbus también se usa para la conexión de un ordenador de supervisión con una unidad remota (RTU) en sistemas de supervisión adquisición de datos (SCADA). Existen versiones del protocolo Modbus para puerto serie y Ethernet (Modbus/TCP).&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Existen dos variantes, con diferentes representaciones numéricas de los datos y detalles del protocolo ligeramente desiguales: &lt;/div&gt;&lt;div&gt;Modbus RTU es una representación binaria compacta de los datos. &lt;/div&gt;&lt;div&gt;Modbus ASCII es una representación legible del protocolo pero menos eficiente. &lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Ambas implementaciones del protocolo son serie. El formato RTU finaliza la trama con un suma de control de redundancia cíclica (CRC), mientras que el formato ASCII utiliza una suma de control de redundancia longitudinal (LRC). La versión Modbus/TCP es muy semejante al formato RTU, pero estableciendo la transmisión mediante paquetes TCP/IP.&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Modbus Plus (Modbus+ o MB+), es una versión extendida del protocolo que permanece propietaria de Modicon. &lt;/div&gt;&lt;div&gt;Dada la naturaleza de la red precisa un coprocesador dedicado para el control de la misma. Con una velocidad de 1 Mbit/s en un par trenzado sus especificaciones son muy semejantes al estándar EIA/RS-485 aunque no guarda compatibilidad con este.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Cada dispositivo de la red Modbus posee una dirección única. Cualquier dispositivo puede enviar órdenes Modbus, aunque lo habitual es permitirlo sólo a un dispositivo maestro. &lt;/div&gt;&lt;div&gt;Cada comando Modbus contiene la dirección del dispositivo destinatario de la orden. Todos los dispositivos reciben la trama pero sólo el destinatario la ejecuta (salvo un modo especial denominado "Broadcast"). &lt;/div&gt;&lt;div&gt;Cada uno de los mensajes incluye información redundante que asegura su integridad en la recepción. Los comandos básicos Modbus permiten controlar un dispositivo RTU para modificar el valor de alguno de sus registros o bien solicitar el contenido de dichos registros.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/36600673-5958633279902104367?l=gepraa.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://gepraa.blogspot.com/feeds/5958633279902104367/comments/default' title='Comentarios de la entrada'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=36600673&amp;postID=5958633279902104367' title='0 Comentarios'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/5958633279902104367'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/5958633279902104367'/><link rel='alternate' type='text/html' href='http://gepraa.blogspot.com/2008/05/modbus-plus.html' title='ModBus Plus'/><author><name>Gabriel Edgardo</name><uri>http://www.blogger.com/profile/15737621644756089532</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='29' src='http://2.bp.blogspot.com/_AVo6d3JS8vM/SJnpz2Bb2xI/AAAAAAAAAJo/Ehd9P9DGx7w/s1600-R/P1010116.JPG'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-36600673.post-6135513188174022270</id><published>2008-05-24T23:04:00.002-03:00</published><updated>2008-12-10T20:53:01.171-02:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Comunicaciones'/><title type='text'>Telegramas de comunicación serial</title><content type='html'>&lt;div&gt;Telegrama serial para Ultra 5000&lt;/div&gt;&lt;a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_AVo6d3JS8vM/SDjL-cAPiaI/AAAAAAAAAHI/hLjkuVHwAjg/s1600-h/ultra5.bmp"&gt;&lt;img style="display:block;

Para estas partes, define categorías y describe propiedades de sus funciones de seguridad. Esto incluye los sistemas programables para toda clase de máquinas y los dispositivos de protección pertinentes. Vale para todas las partes de controles relacionados con la seguridad, independientemente del tipo de energía utilizado, por ejemplo, eléctrica, hidráulica, neumática, mecánica, y se aplica a todas las máquinas del ámbito industrial y privado. Cuando proceda, puede aplicarse también a controles con elementos de seguridad que se utilicen para otras finalidades técnicas con peligros similares.&lt;br /&gt;&lt;a name="anker_2700_6"&gt;&lt;/a&gt;&lt;br /&gt;&lt;strong&gt;EN/IEC 61508:&lt;/strong&gt;&lt;br /&gt;Seguridad funcional de los sistemas eléctricos/electrónicos/electrónicos programables relacionados con la seguridad&lt;br /&gt;Mediante la IEC 61508 se definen los requisitos para los sistemas de seguridad de una instalación independientemente de la aplicación. No se trata solamente de aproximar la reglamentación nacional a las normas internacionales. Cada vez se utilizan más dispositivos y sensores con microprocesadores para funciones de seguridad.En el estándar para "seguridad funcional", los requisitos para estos sistemas se dividen generalmente en Safety Integrity Levels (SIL 1-4). Según esto, los dispositivos, sensores y controles deben recibir una clasificación SIL&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;Parte 1:&lt;/strong&gt; Introduce el concepto de seguridad funcional y proporciona una vista general de las normas de la serie IEC 61508.&lt;br /&gt;&lt;strong&gt;Parte 2:&lt;/strong&gt; Requisitos para los sistemas eléctricos/electrónicos/electrónicos programables relacionados con la seguridad&lt;br /&gt;&lt;strong&gt;Parte 3:&lt;/strong&gt; Requisitos de software&lt;br /&gt;&lt;strong&gt;Parte 4:&lt;/strong&gt; Conceptos y abreviaturas&lt;br /&gt;&lt;strong&gt;Parte 5:&lt;/strong&gt; Ejemplos para determinar el nivel de integridad de seguridad&lt;br /&gt;&lt;strong&gt;Parte 6:&lt;/strong&gt; Directrices para la aplicación de las partes 2 y 3&lt;br /&gt;&lt;strong&gt;Parte 7:&lt;/strong&gt; Instrucciones de aplicación para procedimientos y medidas&lt;br /&gt;&lt;a name="anker_2700_5"&gt;&lt;/a&gt;&lt;br /&gt;&lt;strong&gt;EN/IEC 61511:&lt;/strong&gt;&lt;br /&gt;Seguridad funcional - Sistemas instrumentados de seguridad para el sector de las industrias de procesos&lt;br /&gt;Esta norma define los requisitos mínimos para los sistemas de técnica de seguridad en la industria de procesos. Se basa en la IEC 61508, pero adaptada a la industria de procesos.

En ella se describe la realización de sistemas de control eléctricos relacionados con la seguridad de las máquinas. Abarca el ciclo de vida completo, desde la fase de diseño hasta la retirada de servicio. La base la forman consideraciones cuantitativas y cualitativas de funciones de seguridad. Está dirigida a los planificadores, diseñadores y usuarios de sistemas de técnica de seguridad.La EN/IEC 62061 figura en la lista de normas armonizadas de la Directiva de máquinas CE, de forma que su aplicación genera el denominado efecto "efecto de presunción".&lt;br /&gt;&lt;a name="anker_2700_7"&gt;&lt;/a&gt;&lt;br /&gt;&lt;strong&gt;EN ISO 13849:&lt;/strong&gt;&lt;br /&gt;Seguridad de las máquinas - Partes de los sistemas de mando relativas a la seguridad&lt;br /&gt;Con la revisión de la norma EN 954-1 se pretende obtener una norma simplificada, razonable, que haga innecesario el manejo de modelos matemáticos complejos. Además de sistemas eléctricos, electrónicos y electrónicos programables, la futura norma EN ISO 13849-1 seguirá contemplando, como hasta ahora, otras tecnologías de control como, p. ej., la fluídica.El ámbito de actuación de la EN ISO 13849-1 planificada describe asimismo las posibilidades de aplicar esta norma a sistemas electrónicos programables para funciones de seguridad.En relación con el tema "validación" se publicó el actual proyecto de norma prEN 954-2 como norma armonizada EN ISO 13849-2 en diciembre de 2003. Por validación se entiende una verificación valorada, incluido el análisis y las pruebas, de las funciones de seguridad y categorías de las partes de sistemas de mando relativas a la seguridad.&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/36600673-7856774879183793446?l=gepraa.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://gepraa.blogspot.com/feeds/7856774879183793446/comments/default' title='Comentarios de la entrada'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=36600673&amp;postID=7856774879183793446' title='0 Comentarios'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/7856774879183793446'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/7856774879183793446'/><link rel='alternate' type='text/html' href='http://gepraa.blogspot.com/2008/05/iec61508.html' title='IEC61508'/><author><name>Gabriel Edgardo</name><uri>http://www.blogger.com/profile/15737621644756089532</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='29' src='http://2.bp.blogspot.com/_AVo6d3JS8vM/SJnpz2Bb2xI/AAAAAAAAAJo/Ehd9P9DGx7w/s1600-R/P1010116.JPG'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-36600673.post-7839205339194733266</id><published>2008-04-13T10:22:00.004-03:00</published><updated>2008-12-10T20:53:01.417-02:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Comunicaciones'/><title type='text'>Comunicaciones en DeviceNet</title><content type='html'>&lt;strong&gt;&lt;span style="font-size:130%;"&gt;DeviceNet Network Overview&lt;br /&gt;&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;The DeviceNet™ network is a flexible and open, low-cost option you can use to connect industrial devices to a network and to eliminate costly and time-consuming hardwiring. Direct connectivity improves communication and provides device-level diagnostics not available or easily accessible through hardwired I/O interfaces.&lt;br /&gt;&lt;br /&gt;DeviceNet is an open standard, it saves you time and money at start-up—a key advantage for OEMs. Because it uses a trunk line/drop line topology, a single DeviceNet cable provides power and communication signal to all devices on the network. This significantly reduces the amount of wiring required and greatly simplifies installation. Adding and removing devices from the network is a simple process—a key advantage for end-users. You do not need to add or remove any wires. Simply connect or disconnect the device to or from the trunk line and configure the scan list. It really is that easy.&lt;br /&gt;&lt;br /&gt;And there is no need to plan ahead for future expansion by laying extra cable or buying additional cabinet space. With DeviceNet, you can expand if and only when you want to.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="font-size:130%;"&gt;Benefits&lt;br /&gt;&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;Interchangeability. Simple devices (e.g., push buttons, motor starters, photo cells, limit switches, etc.) from multiple vendors that comply with DeviceNet network and device profile standards are interchangeable, giving users flexibility and choices.&lt;br /&gt;One common network. An open device network standard provides common end-user solutions, reducing the need for vendors to support a variety of the device networks on the market.&lt;br /&gt;Reduce downtime. Diagnostics provide predictive failure warnings and troubleshooting.&lt;br /&gt;Reduction in plant wiring (eliminates hardwiring of I/O).&lt;br /&gt;Lower installation, start-up, and maintenance times. Superior device-level diagnostics.&lt;br /&gt;Ability to bridge to higher level networks.&lt;br /&gt;Device Plug and Play capabilities—add or remove nodes on the fly.&lt;br /&gt;Monitor your systems remotely; program and configure during run-time.&lt;br /&gt;&lt;br /&gt;&lt;span style="font-size:130%;"&gt;&lt;strong&gt;Product Design&lt;/strong&gt;&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;The DeviceNet network provides more than just a protocol specification. It provides interoperability through standardized:&lt;br /&gt;Open- and sealed-type device connectors.&lt;br /&gt;Diagnostic indicators (LEDs).&lt;br /&gt;Device profiles.&lt;br /&gt;&lt;br /&gt;In addition to reading the state of on/off sensors and operating motor starters, the DeviceNet network can report temperatures and the load current in the motor starter, change the deceleration rate of drives, adjust the sensitivity of sensors, and more. Devices also may be removed and replaced without shutting down other devices and without programming tools, which helps lower maintenance costs.&lt;br /&gt;&lt;br /&gt;Networked device installation is more cost-effective than traditional I/O wiring in many applications, particularly when devices are spread over several hundred feet.&lt;br /&gt;Communication&lt;br /&gt;&lt;br /&gt;The DeviceNet network is based on proven, well-known CAN technology, which helps to ensure both end user and industry-wide understanding and acceptance.&lt;br /&gt;&lt;br /&gt;An open device network standard helps to improve overall productivity by giving end users more choices and encouraging device innovations that can improve accuracy, provide diagnostics, and increase the amount of process data.&lt;br /&gt;&lt;br /&gt;Messages from a node on either a ControlNet link or an Ethernet link can be routed through the ControlLogix to a node on a DeviceNet link.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="font-size:130%;"&gt;Typical Applications&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;br /&gt;The DeviceNet network is ideal for applications requiring:&lt;br /&gt;Wire reduction.&lt;br /&gt;Quick installations and start-ups.&lt;br /&gt;Flexibility to add or move devices and cable segments.&lt;br /&gt;Fast response time.&lt;br /&gt;Diagnostics from devices for critical uptime requirement.&lt;br /&gt;Device configuration.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="font-size:130%;"&gt;DeviceNet Typical Configuration&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;img id="BLOGGER_PHOTO_ID_5188721112641785682" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="http://2.bp.blogspot.com/_AVo6d3JS8vM/SAIKXGWVT1I/AAAAAAAAAGk/DgFY28237m8/s400/dbn.bmp" border="0" /&gt;&lt;br /&gt;&lt;a href="javascript:;"&gt;&lt;/a&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/36600673-7839205339194733266?l=gepraa.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://gepraa.blogspot.com/feeds/7839205339194733266/comments/default' title='Comentarios de la entrada'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=36600673&amp;postID=7839205339194733266' title='1 Comentarios'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/7839205339194733266'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/7839205339194733266'/><link rel='alternate' type='text/html' href='http://gepraa.blogspot.com/2008/04/devicenet-network-overview.html' title='Comunicaciones en DeviceNet'/><author><name>Gabriel Edgardo</name><uri>http://www.blogger.com/profile/15737621644756089532</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='29' src='http://2.bp.blogspot.com/_AVo6d3JS8vM/SJnpz2Bb2xI/AAAAAAAAAJo/Ehd9P9DGx7w/s1600-R/P1010116.JPG'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://2.bp.blogspot.com/_AVo6d3JS8vM/SAIKXGWVT1I/AAAAAAAAAGk/DgFY28237m8/s72-c/dbn.bmp' height='72' width='72'/><thr:total>1</thr:total></entry><entry><id>tag:blogger.com,1999:blog-36600673.post-8984294424151274533</id><published>2008-04-10T21:19:00.005-03:00</published><updated>2008-12-10T20:53:02.528-02:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Comunicaciones'/><title type='text'>Comunicaciones en ControlNet</title><content type='html'>&lt;div&gt;&lt;br /&gt;&lt;br /&gt;&lt;div&gt;&lt;span style="font-size:130%;"&gt;&lt;strong&gt;&lt;span style="color:#006600;"&gt;ControlNet Network Overview&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;ControlNet is an open, industrial, real-time control-layer network that provides high-speed transport of both time-critical I/O and interlocking data and messaging data, including upload/download of programming and configuration data on a single physical media link. The ControlNet network's highly efficient data transfer capability significantly enhances I/O performance and peer-to-peer communication in any system or application where it is used.&lt;br /&gt;&lt;br /&gt;ControlNet is highly deterministic and repeatable, and remains unaffected as devices are connected or disconnected from the network. This ensures dependable, synchronized, and coordinated real-time performance. The ControlNet network is most often used in these types of configurations:&lt;br /&gt;As the default network for the ControlLogix platform.&lt;br /&gt;As a substitute/replacement for the Remote I/O (RIO) network, because ControlNet handles large numbers of I/O points well.&lt;br /&gt;As a backbone to multiple distributed DeviceNet networks.&lt;br /&gt;As a peer interlocking network.&lt;br /&gt;&lt;br /&gt;Rockwell Automation offers a full array of ControlNet products, including controllers, I/O, operator interfaces, media, drives, motion control, and software. We have the products and know-how you need to set up a new ControlNet system, and the products and innovations you need to maintain and grow your existing applications. Flexible installation options for the ControlNet network include:&lt;br /&gt;Fiber media for optical isolation from noise and distances up to 20 km.&lt;br /&gt;Redundant Media Option helps ensure that a system can maintain operation during a cable fault condition.&lt;br /&gt;Intrinsic Safety Option lets you install a ControlNet network in hazardous, explosive locations. Choose between either long-distance fiber or low-cost coax options to span between hazardous and non-hazardous areas.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="font-size:130%;"&gt;Benefits&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;br /&gt;Implements programming, processor-to-processor, and I/O control on the same link without impacting time-critical I/O.&lt;br /&gt;Media redundancy and intrinsically-safe options.&lt;br /&gt;Provides the functions of the Data Highway Plus and Universal Remote I/O networks at a 5M-bit/s rate.&lt;br /&gt;Offers high-speed data throughput, which improves I/O performance and controller-to-controller interlocking.&lt;br /&gt;Supports a maximum of 99 nodes, with no minimum distance between them.&lt;br /&gt;Lets you access the network from any node for PLC processor programming and troubleshooting.&lt;br /&gt;Multicast of both inputs and peer-to-peer data for reduced programming.&lt;br /&gt;Incorporates improved system diagnostics, which make it easier to configure and maintain.&lt;br /&gt;Has finer granularity of I/O.&lt;br /&gt;Gives you deterministic, repeatable transfers of data to/from digital and analog I/O.&lt;br /&gt;Lets you select I/O and PLC processor interlocking update times that match your application requirements.&lt;br /&gt;Eliminates block-transfer programming.&lt;br /&gt;Is compatible with a range of current Allen-Bradley products, and will be compatible with more in the future.&lt;br /&gt;Provides operation through high-noise environment with fiber-optic segments.&lt;br /&gt;Messages from/to a node on one ControlNet link can be routed through the ControlLogix gateway to/from a node on either another ControlNet link, a DH+ link, or an EtherNet/IP link.&lt;br /&gt;&lt;br /&gt;&lt;span style="font-size:130%;"&gt;&lt;strong&gt;Product Design&lt;br /&gt;&lt;/strong&gt;&lt;/span&gt;&lt;br /&gt;The ControlNet network is simple and cost-effective to install, and offers you many flexible installation options, such as PLC processors with built-in ControlNet scanners, ControlNet bridges and adapters for I/O chassis, and ControlNet computer interfaces for personal computers. Although the ControlNet network is based on bus technology, you can use repeaters to implement ring, and star topologies. You can also install optional redundant media. The ControlNet processors include ports that let you share data between a ControlNet network and your already installed Data Highway Plus and Universal Remote I/O networks.&lt;br /&gt;&lt;br /&gt;The ControlNet network transfers scheduled data at 5M bit/s, which improves both I/O performance and processor-to-processor communication. Its flexible control system architecture can work with multiple processors, and you can install up to 99 addressable nodes (via taps) anywhere along the trunk cable of a ControlNet link. There is no minimum tap separation, and you can access the ControlNet network from every node (including adapters).&lt;br /&gt;&lt;br /&gt;Types of devices that communicate on the ControlNet link include: controllers, I/O, HMIs, PCs, drives, coordinated drive systems, weld control, motion control, vision systems, transducers, and valve manifolds.&lt;br /&gt;&lt;br /&gt;In addition, a ControlNet network can be configured using a bus/trunkline, star, or ring topology.&lt;/div&gt;&lt;br /&gt;&lt;br /&gt;&lt;div&gt;&lt;/div&gt;&lt;br /&gt;&lt;br /&gt;&lt;div&gt;&lt;/div&gt; &lt;img id="BLOGGER_PHOTO_ID_5187779035306181090" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="http://4.bp.blogspot.com/_AVo6d3JS8vM/R_6xi-ykweI/AAAAAAAAAGU/vHqQC1Dy4ds/s400/cnet.JPG" border="0" /&gt;&lt;br /&gt;&lt;br /&gt;&lt;div&gt;&lt;/div&gt;&lt;br /&gt;&lt;br /&gt;&lt;div&gt;&lt;/div&gt;&lt;br /&gt;&lt;br /&gt;&lt;div&gt;&lt;strong&gt;&lt;span style="font-size:130%;"&gt;Communication&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;br /&gt;The ControlNet network provides the functions of the Allen Bradley Data Highway Plus and Universal Remote I/O networks at a 5M-bit/s rate. Multiple processors can each control their own assigned outputs on a single common ControlNet link and monitor all inputs on the link. Any processor on the link can send a message to any other processor on the link.&lt;br /&gt;&lt;br /&gt;Messages from a node on one ControlNet link can be routed through the ControlLogix gateway to a node on either another ControlNet link, a DeviceNet link, a DH+ link, or an EtherNet/IP link.&lt;/div&gt;&lt;br /&gt;&lt;br /&gt;&lt;div&gt;&lt;/div&gt;&lt;br /&gt;&lt;br /&gt;&lt;div&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="font-size:130%;"&gt;ControlNet I/O&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;br /&gt;Rockwell Automation's I/O family provides world-class I/O products for virtually every ControlNet application need.

La misma red está compuesta por un total de 11 CPUs físicas que poséen en su rack principal por lo menos una CP5431FMS con soporte de memoria en EPROM convencional de 32Kb.&lt;br /&gt;&lt;br /&gt;El protocolo que se debe usar es el llamado "Profibus S5 messaging" desarrollado por SIEMENS de Francia para Applicom.&lt;br /&gt;&lt;br /&gt;El actual protocolo de la red existente llamado "Sinec L2 FDL" que opera por medio del servicio "S5-S5 link" de la CP5431 es el que establece la conectividad con los otros PLCs y antiguas PC y que usaban como interfece local 2 tarjetas CP5412A2 con un paquete de software SofNet de Siemens para WNT. Este protocolo es inviable cuando se utiliza la tarjeta Applicom PC1500PFB dado que las funciones de escritura sobre los equipos remotos no está soportada y esto es fundamental para nuestras 2 aplicaciones dado que establece una comunicación indirecta por batch con un máximo de 64 words por telegrama y entonces se hace necesario el paginado cuyo puntero obedece a variables como ser número de pantalla de un SCADA cliente.&lt;br /&gt;&lt;br /&gt;Se propone entonces el uso del protocolo desarrollado por Siemens Francia para&lt;br /&gt;Applicom el cual permite leer y escribir sobre los operandos del Simatic S5 en forma&lt;br /&gt;cíclica o periódica indistintamente, tal cual trabaja cualquier OPC moderno conocido&lt;br /&gt;v2.0 ó v3.0 (similar RSlinx o KepServerEx4.00).&lt;br /&gt;&lt;br /&gt;Se deberán realizar los siguientes pasos a grandes rasgos para conseguir esta&lt;br /&gt;conectividad:&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;A) Configuración de la consola Applicom para protocolo S5m en cada uno de los nodos de la red teniendo en cuenta nº de SAPs locales y remotos.&lt;br /&gt;&lt;br /&gt;B) Implementación de la nueva capa en la red Sinec llamada "L2 free layer"&lt;br /&gt;utilizando el software NCM COM5431FMS instalado en un PG y un borrador UV de&lt;br /&gt;EPROM.&lt;br /&gt;&lt;br /&gt;C) Adecuación del programa en STEP5 de cada CPU total 3 bloques y descarga de 2&lt;br /&gt;bloques funcionales, 2 bloques de datos y un bloque organizacional.

The recommended arrangement of the wires is as a connected series of point-to-point nodes, a line or bus. Ideally, the two ends of the cable will have a termination resistor connected across the two wires and two powered resistors to bias the lines apart when the lines are not being driven. The value of each termination resistor should be equal to the cable impedance (typically, 120 ohms for twisted pairs). &lt;/div&gt;&lt;div&gt; &lt;/div&gt;&lt;div&gt; &lt;/div&gt;&lt;div&gt;EIA-485 (formerly RS-485 or RS485) is an OSI Model physical layer electrical specification of a two-wire, half-duplex, multipoint serial connection. The standard specifies a differential form of signalling. The difference between the wires’ voltages is what conveys the data. One polarity of voltage indicates a logic 1 level, the reverse polarity indicates logic 0. The difference of potential must be at least 0.2 volts for valid operation, but any applied voltages between +12 V and -7 volts will allow correct operation of the receiver. EIA-485 is better described as &lt;a href="http://pinouts.ru/definition/balanced-unbalanced.shtml"&gt;un-balanced&lt;/a&gt; interface, as the balanced normallly implies that the voltages on the differential wires are balanced with respect to ground or earth potential (eg +5V and -5V), but EIA-485 is usually +5V and 0V .&lt;br /&gt;EIA-485 only specifies electrical characteristics of the driver and the receiver. It does not specify or recommend any data protocol. Since it uses a differential line over twisted pair (like EIA-422), it can span relatively large distances (up to 4000 feet or just over 1200 metres). The recommended arrangement of the wires is as a connected series of point-to-point nodes, a line or bus. Ideally, the two ends of the cable will have a termination resistor connected across the two wires and two powered resistors to bias the lines apart when the lines are not being driven. Without termination resistors, reflections of fast driver edges can cause multiple data edges that can cause data corruption. The value of each termination resistor should be equal to the cable impedance (typically, 120 ohms for twisted pairs). &lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1'

called a SCI, COM, or ASYNC port) often do not generate the proper voltages required for connecting to computer RS-232 serial port. In this case special converter needed. Most microcontrollers run on a single supply voltage, that is usually +5 volts. In rough terms, logical 1 on these devices indicates that +5 is the voltage on the output pin. Logical 0 specifies that 0 volts is on the line.&lt;br /&gt;The RS-232-C standard specifies that the voltage on the wire for sending a logical 0 are from +5v to +15v. The voltage for sending a 1 are from -5v to -15v. Most microcontrollers not capable of generating these voltages. So, to connect a microcontroller serial port to a true RS-232 device, you need to convert the TTL voltages of 0 and +5 into voltages between about -10 volts and +10 volts.&lt;br /&gt;MAX232 is the chip that makes this work for you. It runs on a single chip supply (+5 volts), contains double charge pump voltage doubler and a +10v to -10v voltage inverter and requires a few external capacitors. There are some versions of this chip. The voltages output are used to generate the RS-232 compliant signals of two serial ports on the same physical package.&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/36600673-2465787536181438332?l=gepraa.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://gepraa.blogspot.com/feeds/2465787536181438332/comments/default' title='Comentarios de la entrada'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=36600673&amp;postID=2465787536181438332' title='0 Comentarios'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/2465787536181438332'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/2465787536181438332'/><link rel='alternate' type='text/html' href='http://gepraa.blogspot.com/2006/12/pinouts-universal-bruce.html' title='Pinouts Universal telefónico'/><author><name>Gabriel Edgardo</name><uri>http://www.blogger.com/profile/15737621644756089532</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='29' src='http://2.bp.blogspot.com/_AVo6d3JS8vM/SJnpz2Bb2xI/AAAAAAAAAJo/Ehd9P9DGx7w/s1600-R/P1010116.JPG'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://3.bp.blogspot.com/_AVo6d3JS8vM/R2_wBogXi-I/AAAAAAAAABM/iOI0e0hLQkg/s72-c/pinout.gif' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-36600673.post-8178981673853336835</id><published>2006-12-03T13:20:00.000-03:00</published><updated>2008-12-10T20:53:09.252-02:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Pinouts'/><title type='text'>Pinouts S7-200</title><content type='html'>&lt;a href="http://3.bp.blogspot.com/_AVo6d3JS8vM/R2_6logXi_I/AAAAAAAAABU/cC55f1iOhXo/s1600-h/Pc_s7_1.jpg"&gt;&lt;img id="BLOGGER_PHOTO_ID_5147608423543049202" style="CURSOR: hand" alt="" src="http://3.bp.blogspot.com/_AVo6d3JS8vM/R2_6logXi_I/AAAAAAAAABU/cC55f1iOhXo/s320/Pc_s7_1.jpg" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;a href="http://4.bp.blogspot.com/_AVo6d3JS8vM/R2_6l4gXjAI/AAAAAAAAABc/cdqL3eupY28/s1600-h/Pc_s7_1.jpg"&gt;&lt;/a&gt;&lt;br /&gt;&lt;div&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/36600673-8178981673853336835?l=gepraa.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/8178981673853336835'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/8178981673853336835'/><link rel='alternate' type='text/html' href='http://gepraa.blogspot.com/2006/12/pinouts-s7-200.html' title='Pinouts S7-200'/><author><name>Gabriel Edgardo</name><uri>http://www.blogger.com/profile/15737621644756089532</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='29' src='http://2.bp.blogspot.com/_AVo6d3JS8vM/SJnpz2Bb2xI/AAAAAAAAAJo/Ehd9P9DGx7w/s1600-R/P1010116.JPG'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://3.bp.blogspot.com/_AVo6d3JS8vM/R2_6logXi_I/AAAAAAAAABU/cC55f1iOhXo/s72-c/Pc_s7_1.jpg' height='72' width='72'/></entry><entry><id>tag:blogger.com,1999:blog-36600673.post-8378021428340074431</id><published>2006-12-03T13:18:00.000-03:00</published><updated>2007-12-24T15:53:09.579-03:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Pinouts'/><title type='text'>Pinouts Telemecanique</title><content type='html'>&lt;strong&gt;&lt;span style="font-size:180%;color:#33cc00;"&gt;Telemecanique.&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="font-size:180%;color:#33cc00;"&gt;&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="color:#3333ff;"&gt;Extracto de un foro antiguo.&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;&lt;br /&gt;Been there..&lt;br /&gt;Done that, with or without their fancy expensive cables.&lt;br /&gt;&lt;span style="color:#ff0000;"&gt;&lt;strong&gt;First&lt;/strong&gt;&lt;/span&gt; question... In the PL-7 pro have you cared to change the protocol from UNITELWAY to MODBUS/J-Bus at the time of downloading ???.&lt;br /&gt;This is necessary as a first step.&lt;br /&gt;&lt;br /&gt;&lt;span style="color:#ff0000;"&gt;&lt;strong&gt;Second&lt;/strong&gt;&lt;/span&gt; point to check out is whether your TSX Micro PLC has a SCP-114 PCMCIA card fitted onto it. I don't recall whether your PLC offers Modfbus protocol on the TER port without the SCP-114 trappings. Some PLCs do some dont.&lt;br /&gt;&lt;br /&gt;Now Modicon Schneider make 2 kinds of cables. One for programming only and a more expensive kind for Programming and communicating with scada. If your cable is of the former kind.&lt;br /&gt;It won,t communicate with I-Fix. or any other scada for the matter.&lt;br /&gt;The more expensive cable for scada -communication as well as PLC programming, comes with a small rotary switch which needs to be turned.&lt;br /&gt;One position for Programming and the perpendicular position for Scada. If your cable has a small switch on the rectangular plastic box turn it and see.&lt;br /&gt;Its a long time since I've stopped buying expensive cables. So I dont care for their model nos.&lt;br /&gt;&lt;br /&gt;&lt;span style="color:#ff0000;"&gt;HOWEVER READ ON FOR THE BASICs and IT WORKS!!!.&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;In the 8 pin Mini Din connector(Male)... Pins 1 &amp;amp; 2 are the active RS-485 signals( The Bottom most row) ie. A &amp;amp; B or D+ &amp;amp; D- In addition the Pin no 5.. ie. the Rightmost pin on the Middle row carries a signal called /DST (Ref Autokit).&lt;br /&gt;This signal has to be PULLED LOW so that the PLC becomes a Slave in the Modbus network. If there is Scada.. PLC has to be a slave and the SCADA being the master..&lt;br /&gt;Now If you connect pins 1 &amp;amp; 2 through a RS-485-Rs232 converter and keep pin 5 open or connected to 5V+ (pin 8 i think) then the cable is good only for downloading your program. But for scada communication.. Pin 5 has to be switched to connect to 0v avaiable in the port. The use of a multimeter unravels all this.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;&lt;span style="color:#ff0000;"&gt;Lastly&lt;/span&gt;&lt;/strong&gt;.. If its OPC/DDE (probably the Modicon MODBUS server) you must have it running in the background,with all the correct addressing for topic name and item name. Remember one last thing Modbus will not show Inputs or Outputs directly. You've to make a copy to Memory bits area ie. %M which is what will show up in SCada. So also the addrtessing of %MW0 is mapped to 40001. OK. Pls try out all this and inform me.&lt;br /&gt;I'd be surprised if my suggestions don't help. Regards and best of luck.. If you are near Mumbai, India. come to my lab and I'll show you how.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style="color:#ff0000;"&gt;&lt;strong&gt;MB+ RS485 pinout&lt;/strong&gt;&lt;/span&gt; configurationAug 9, 2004 6:22 pm, by A.KilaniSubject : PLCs from the Automation dept.

Reply&lt;br /&gt;&lt;br /&gt;--------------------------------------------------------------------------------&lt;br /&gt;Re: MB+ RS485 pinout configurationAug 10, 2004 3:36 pm, by Brian CerviModbus Plus, although a "RS485" like interface should not be regarded as such. You cannot simply use a RS232/485 convertor on Modbus Plus networks.&lt;br /&gt;You can connect Modbus Plus from a PLC to a PC (or host) using one of the compatible Modbus Plus network modules for your PC.&lt;br /&gt;From experience... when possible, use the PLC vendor supplied network components for Industrial Networks. That way compatibility is assured. Cable substitutions especially look attractive but often end up costing more to fix than ever was saved. Reply&lt;br /&gt;Re: MB+ RS485 pinout configurationAug 10, 2004 3:23 pm, by JDNo, Modbus Plus is a proprietary protocol.&lt;br /&gt;However you can talk to the Quantum PLC directly through it's RS232 Modbus port.

Just wire it 'straight through'. Then, go to the local electronics shop and get an RJ45-to-DB9 serial adapter. That adapter will allow you to assign the RJ45 connectors to the DB9 pins of your choosing.

Reply&lt;br /&gt;Re: TSXPCX1031cable for RS485 connection to port1 of twidoJun 3, 2005 8:29 pm, by AnonymousYes it is possible. You have to select position 3 in PCX1031. Programming is using position 2. Ofcourse port parameter have to set correctly. By default it is remotelink. Reply&lt;br /&gt;&lt;br /&gt;Re: TSXPCX1031cable for RS485 connection to port1 of twidoJun 3, 2005 12:32 am, by AlastairThe TSXPCX1031 cable is the specified serial programming lead for the Twido PLC. You must turn the switch on the cable to position 2 for programming. The Twido uses Modbus as it's native communications protocol. You may have to use Twidosoft to configure Port 1 with the appropriate settings (Modbus, addr 1, 9600,8,E,1) if you are using a different adapter to access the Twido.

Estas son las aplicaciones de bajo nivel de Microsoft para tecnologías ActiveX, OLE, DirectX, etc. cuando se llama a alguna interfáz.&lt;br /&gt;Para utilizar con eficacia un cliente, se recomienda que el usuario tenga un cierto conocimiento de la especificación de OPC o cierta experiencia práctica práctica del mismo.&lt;br /&gt;Hay muchas cosas que no estaban disponibles en DDE y que ahora lo están vía OPC. Ésto incluye una gestión mejorada de grupos y TAGs, y también la capacidad de permitir al usuario utilizar servidores alejados usando DCOM.&lt;/span&gt;&lt;/em&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;p&gt;&lt;span style="font-size:180%;color:#333399;"&gt;&lt;strong&gt;&lt;em&gt;Historia de la fundación y la especificación OPC.&lt;/em&gt;&lt;/strong&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;La fundación OPC nace en el año 1995 como iniciativa de las firmas, Rockwell Software, Intellution, F-Rosemount, Opto-22, Intuitiv Software y Microsoft con el propósito de definir una serie de especificaciones en base a COM y DCOM.&lt;br /&gt;Luego con el aporte de otras numerosas firmas de peso internacional, que hicieron las veces de pilotos de prueba, se verificaron estas especificaciones y se oficializaron en el año 1996.&lt;br /&gt;El objetivo primario consistía en brindar una interfaz para programación de aplicaciones estándar para el intercambio de datos que pudiese simplificar el desarrollo de drivers y mejorar el rendimiento de los sistemas de interfaz.&lt;br /&gt;&lt;br /&gt;La siguiente figura muestra el antiguo modelo de arquitectura de automatización industrial basado en drivers.&lt;/p&gt;&lt;br /&gt;&lt;a href="http://photos1.blogger.com/blogger2/7009/4467/1600/driver%20antiguos.jpg"&gt;&lt;img style="CURSOR: hand" alt="" src="http://photos1.blogger.com/blogger2/7009/4467/400/driver%20antiguos.jpg" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;p&gt;La fundación OPC publicó un documento en 1998, poniendo en común los problemas típicos de la arquitectura habitualmente usada, como ser:&lt;br /&gt;&lt;/p&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;ul&gt;&lt;li&gt;Se deben desarrollar programas asociados a un driver para el hardware de un vendedor específico.&lt;br /&gt;&lt;/li&gt;&lt;br /&gt;&lt;li&gt;Las características de hardware no son soportadas por todos los drivers.&lt;br /&gt;&lt;br /&gt;&lt;/li&gt;&lt;li&gt;Un cambio en las capacidades del hardware puede ocasionar conflictos en los drivers.&lt;br /&gt;Dos o más aplicaciones no pueden acceder simultáneamente al mismo dispositivo.&lt;br /&gt;&lt;br /&gt;&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;Los fabricantes de hardware procuran resolver estos problemas desarrollando nuevos drivers, pero se encuentran con que no se puede desarrollar un driver eficiente que pueda ser utilizado por todos los tipos de clientes que existen.&lt;br /&gt;&lt;br /&gt;No existe entonces una forma homologada de definir las conexiones dejando depender del tipo de dispositivo, complicando así los desarrollos industriales.&lt;br /&gt;&lt;/p&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;p&gt;El OPC eliminó este problema estableciendo una interfaz de comunicación común, lo cual ha beneficiado de manera asombrosa el desarrollo de aplicaciones HMI y SCADA.&lt;br /&gt;&lt;br /&gt;En este gráfico se ve representada la idea sobre un ambiente de control y monitoreo industrial basado en el concepto OPC:&lt;/p&gt;&lt;a href="http://photos1.blogger.com/blogger2/7009/4467/1600/OPC1.0.jpg"&gt;&lt;img style="CURSOR: hand" alt="" src="http://photos1.blogger.com/blogger2/7009/4467/320/OPC1.0.jpg" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;p&gt;&lt;strong&gt;OPC Foundation&lt;/strong&gt;

es una especificación no propietaria definida por la OPC Foundation y es básicamente un sistema de interfaces estándar basado en OLE/COM de Microsoft.&lt;br /&gt;Con OPC se logra operar entre dispositivos industriales y sistemas de información o aplicaciones de escritorio.&lt;br /&gt;De esta manera OPC permite desarrollar de una manera práctica y eficiente aplicaciones que se puedan conectar con equipos industriales controlados por autómatas y/o sistemas distribuidos.&lt;/p&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;p&gt;&lt;strong&gt;Las Ventajas de OPC&lt;/strong&gt;

Se debe crear un objeto OPCServer antes de poder referenciar los otros objetos. Este contiene la colección OPCGroups y el objeto OPCBrowser.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;OPCGroups&lt;br /&gt;&lt;/strong&gt;Es una colección de los objetos OPCGroup que el cliente ha creado.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;OPCGroup&lt;br /&gt;&lt;/strong&gt;El propósito de este objeto es mantener la información de estado y proveer el mecanismo para ofrecer los servicios de adquisición de datos por la colección de objetos OPCItem.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;OPCItems&lt;br /&gt;&lt;/strong&gt;Es una colección que contiene todos los objetos OPCItem que el cliente ha creado.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;OPCItem&lt;/strong&gt;&lt;br /&gt;Es un objeto que mantiene la definición de los items, sus valores, estados y datos de la última actualización.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;OPCBrowser&lt;br /&gt;&lt;/strong&gt;Es un objeto que permite buscar nombres de items en un servidor configurado.&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Un servidor de acceso a datos OPC&lt;/strong&gt; se compone de varios objetos: servidor, grupo y elemento.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;El servidor de objetos OPC&lt;/strong&gt; ofrece información sobre el servidor y sirve como un contenedor de grupos de objetos.&lt;br /&gt;&lt;strong&gt;El grupo de objetos OPC&lt;/strong&gt; mantiene información acerca de sí mismo y provee los mecanismos para contener y organizar los elementos OPC.&lt;br /&gt;&lt;strong&gt;Los grupos OPC&lt;/strong&gt; proporcionan una forma para organizar los datos de los clientes, por ejemplo: el grupo podría representar los elementos en un pantalla particular de operador o en una planilla de informes; los datos pueden ser leídos y escritos, y las conexiones basadas en excepciones, pueden ser creadas entre el cliente y los elementos en el grupo y pueden ser activadas y desactivadas según sea necesario.&lt;br /&gt;&lt;strong&gt;Un cliente OPC&lt;/strong&gt; puede configurar que cantidad de datos deben ser cambiados antes de la actualización.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;Existen grupos públicos y locales&lt;/strong&gt;; los públicos se comparten entre varios clientes, mientras que los locales son privados para el cliente en cuestión.&lt;br /&gt;Existen interfaces opcionales para los grupos públicos; el cliente puede definir uno o más elementos OPC.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Los elementos representan conexiones a datos dentro del servidor; un elemento OPC, no es accesible por el cliente como un objeto.&lt;/p&gt;&lt;p&gt;No hay una interfaz externa definida para un elemento OPC; todos los accesos al elemento se realizan a través del objeto grupo OPC que contiene el elemento, o simplemente el grupo en el que fue definido.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;Cada elemento tiene asociado un valor y calidad de información como así también un tiempo.&lt;br /&gt;&lt;/strong&gt;Los elementos no son fuentes de los datos sino que son conexiones a ellos; al elemento OPC se lo debe ver como la dirección de un dato, no como la fuente del mismo, la fuente real de los datos es el dispositivo de control.&lt;br /&gt;&lt;br /&gt;&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/36600673-8974930476230246223?l=gepraa.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/8974930476230246223'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/8974930476230246223'/><link rel='alternate' type='text/html' href='http://gepraa.blogspot.com/2006/11/opc.html' title='DDE y OPC'/><author><name>Gabriel Edgardo</name><uri>http://www.blogger.com/profile/15737621644756089532</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='29' src='http://2.bp.blogspot.com/_AVo6d3JS8vM/SJnpz2Bb2xI/AAAAAAAAAJo/Ehd9P9DGx7w/s1600-R/P1010116.JPG'/></author></entry><entry><id>tag:blogger.com,1999:blog-36600673.post-3475224271231450409</id><published>2006-11-06T16:16:00.001-03:00</published><updated>2008-09-20T11:00:01.968-03:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Experiencias'/><title type='text'>Up-grade de PLC-2 AB</title><content type='html'>&lt;a href="http://photos1.blogger.com/blogger2/7009/4467/1600/logo%20Gepraa%20con%20sombra.7.jpg"&gt;&lt;/a&gt;&lt;br /&gt;&lt;div&gt;&lt;/div&gt;&lt;br /&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;&lt;span style="font-size:180%;color:#006600;"&gt;Revamping de PLC-2 a SLC500&lt;/span&gt;&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;&lt;span style="font-size:180%;color:#006600;"&gt;de Allen Bradley&lt;/span&gt;&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;&lt;span style="font-size:180%;color:#006600;"&gt;&lt;/span&gt;&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;&lt;span style="font-size:180%;color:#006600;"&gt;&lt;/span&gt;&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;Cuando se trata de producir un Up-grade a un viejo PLC-2 de Allen Bradley, se supone que la solución directa y sencilla es un simple reemplazo de CPU y en todo caso de chassis, pero esto puede resultar costosísimo.&lt;br /&gt;Surge en su lugar la alternativa de utilizar el sistema SLC500 en lugar del sistema PLC-2, PLC-3 ó PLC-5.&lt;br /&gt;Sin embargo este reemplazo puede no resultar tan directo, razón por la cual se deben tener en cuenta ciertas consideraciones que no se expresan claramente en casi ninguna documentación circulante.

I am looking to connect 3 Thermocouples with the 1771 IFE analog input module. Can you please send me a ladder program example involving more then one analog input.&lt;br /&gt;Best Regards,&lt;br /&gt;Engr. Naeem MaqboolLahore, Pakistan.&lt;br /&gt;Greetings Naeem,&lt;br /&gt;&lt;br /&gt;First of all, you should post all of your requests in the forum’s Question and Answer section ... you will get much better results when all members have a chance to respond ... next, we need more information about your project in order to give you any useful advice ...&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;Issue #1: you said you are working on an SLC-500 ... are you sure about that? ... more likely you are working on an SLC-5/01, or SLC-5/02, or SLC-5/03, or SLC-5/04, or SLC-5/05 ... all of these are sometimes referred to by their “family name” of SLC-500 ... we need to know which processor you are using in order to help you ... it is also possible that you are working with a PLC-5 processor ... (see next issue) ...&lt;br /&gt;&lt;/p&gt;&lt;/span&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;Issue #2: the 1771-IFE module that you mentioned will not fit in the same chassis with any of the small SLC-500 processors ... specifically, it is designed for use with the larger PLC-5 system ... it Is possible to use the 1771-IFE module with the smaller SLC-500 processor - but it must be done by installing the 1771-IFE in a “remote I/O” configuration ... specifically, the larger module would be installed in a separate chassis and would communicate with the SLC-500 processor over a “remote I/O” cable ... if that is what you’re trying to set up, then we need to know what “scanner” module (example: 1747-SN) and what “adapter” module you’re using (example: 1771-ASB) ... it would also help to know how your system is configured ... specifically, we need to know what “rack” and “group”, etc. your remote rack is set for ... this is done with DIP switch settings on the 1771-ASB adapter module ...&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;Issue #3: you said that you want to connect 3 thermocouples to the 1771-IFE module ... the 1771-IFE does not accept thermocouple inputs connected directly to the module ... instead, each of the thermocouples must be connected to a separate “transmitter” ... this transmitter will take the millivolt output of the thermocouple and convert it into a 4 to 20 milliamp signal ... this 4 to 20 milli Amp signal can then be connected to the 1771-IFE module ... (note: there are other ways of doing this, but this is the most common method) ... connecting the signals to the 1771-IFE will require that you have an understanding of wiring “single-ended” and “differential” signals ... are you familiar with those terms? ... and is your 1771-IFE module already configured for one method or the other? ... specifically, is the module already in use for existing signals - to which the 3 thermocouples will be added? ... note that wiring the 1771-IFE module correctly will require that you set the position of a series of small “jumpers” which are located inside the module ...&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;Issue #4: is it possible that you meant to say that you will be using a 1771-IXE module (rather than a 1771-IFE)? ... if so, the 1771-IXE will accept thermocouple inputs wired directly to the module ...&lt;br /&gt;issue #5: in any event, we’ll need to know what type of thermocouples you’ll be using ... example: type J, type K, etc. ... if you’re using the 4 to 20 milliamp transmitter method, then we’ll also need to know the scaling for your system ... example: 4 milliamps equals 32 degrees Fahrenheit ... 20 milliamps equals 212 degrees Fahrenheit ... etc. ...&lt;br /&gt;issue #6: all of these issues must be covered before we can offer you any specific examples of programming code ... but a basic idea is this: you must “configure” the 1771-IFE module with a BTW (Block Transfer Write) command rung ... this will force the processor to send a block of several words of data to the 1771-IFE module to tell it how it is expected to perform (scaling, number format, etc.) ... then you must program a BTR (Block Transfer Read) command rung which will execute repeatedly ... this will force the processor to retrieve information from the 1771-IFE module and place the information in the processor’s memory table - usually in a series of Integer-type locations ... if all else is done correctly, the readings from all 3 thermocouples will be contained in that one block of information ... example: in words N7:54, N7:55, and N7:56 ... normally the readings are all scaled from 0 to 4095 as raw data ... then we usually program separate math functions to scale the data into readings of degrees Fahrenheit or Celsius ... or it is also possible to “configure” the 1771-IFE module to provide the scaling internally ...&lt;br /&gt;&lt;br /&gt;As you can see, the task that you have outlined is not a trivial undertaking ... but if you’ll be good enough to give us all of the details about your system, we’ll be glad to try to help ... personally, I’ll be offline and unavailable most of next week ... so I am posting your request on the forum’s main Question and Answer board in the hopes that some other members will be able to help you ...&lt;br /&gt;&lt;br /&gt;I hope that this information will help get you started ... I wish you good luck ...&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;Best regards,Ron &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;&lt;a href="http://www.ind-info.com/"&gt;http://www.ind-info.com/&lt;/a&gt; &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;Ron Beaufort View Public Profile Send a private message to Ron Beaufort Find More Posts by Ron Beaufort Add Ron Beaufort to Your Buddy List&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;July 18th, 2005, 01:44 AM #3 roomi117 Member&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;Dear Sir,Thank you for your detailed reply. Let me first tell you about my project. I have got 3 digital inputs (2 On/Off P.B for heaters, 1 pressure Switch) and 3 analog inputs (3 thermocouples). The heaters will be turned on after we Push the Push Buttons and the thermocouples will start monitoring the temperature of heaters. At 150 Degree the two solenoid valves will be actuated.This is the main part of the project. Rest are very simple. Previousely I have worked on the PIC Micro Controllers but in Industry the PLC's are prefered more. I don't have much experience working with PLC's but I can do a few things.&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;Thanks and Regards,&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;Engr.

Are you using existing hardware at your school? Are you planning on purchasing the hardware? If you are using existing hardware, I would recommend that you list the part numbers of the equipment that you have. That way the board can help you decide which parts work together.&lt;br /&gt;Also, there is the software question, do you have the software and cables required to program whatever PLC you are using? So far you've mentioned two different PLC platforms, I would suggest you try and stick with one platform, it is usually easier for beginning programmers."To give real service you must add something that cannot be bought or measured with money; and that is sincerity and integrity."&lt;br /&gt;&lt;/p&gt;&lt;/span&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;- Donald A.

The thing is I don't have much experience working with Allen Bradly PLC's. The problem is mentioned above, can you tell me which processor &amp;amp; I/O modules to use.The other problem is that I haven't worked with the analog I/O. We can use PLC-5 processor &amp;amp; 1771-IXE as mentioned by Ron. I have downloaded a few PDFs regarding the BTW and BTR commands but I am not clear completely as how to use these for more than one anlog input.I look forward for your kind reply.Regards,&lt;br /&gt;Naeem. roomi117 View Public Profile Send a private message to roomi117 Find More Posts by roomi117 Add roomi117 to Your Buddy List&lt;br /&gt;July 18th, 2005, 06:18 AM #6 roomi117 Member&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Join Date: Jul 2005Local Time is: 10:33 PM Location: LahorePosts: 11 I have SLC-5/05 model and the RSLogix 500 software.

The NI8 is easier to scale than the NI4. At 150 degC PT100s will give better results than thermocouples. This is a bit more expensive but allows the other analog channels on the NI8 to be used for other purposes. The thermocouple module is the 1746 NT4.

That way you will not have to tackle the Block transfer logic. The next question is do have or can you get a 1746-NT4 or NT8, for your thermocouple inputs?

Sounds like you just have contact closure devices, that is nothing electronic.So you could get by with several different input modules. Do you have any 1746 input modules on hand? You are also going to need an output module for the solenoids, what are the specifications for the solenoids?Do you have a chassis? a power supply? Come on we're trying to help, but you are being very stingy with your information.&lt;br /&gt;If you would give us a more complete idea of what you have and what exactly you are trying to do, we wouldn't have to keep asking so many questions. You are answering detailed questions with simple answers, notthe best method of exchanging information.&lt;br /&gt;&lt;br /&gt;--------------------------------------------------------------------------------&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;Last edited by Ken Moore : July 18th, 2005 at 08:10 AM.

Can you send me program involving three thermocouples at the input module. I can arrange the 1746-NT4 or the 1771-IXE modules. roomi117 View Public Profile Send a private message to roomi117 Find More Posts by roomi117 Add roomi117 to Your Buddy List&lt;br /&gt;July 18th, 2005, 08:54 AM #14 Ken Moore Member&lt;br /&gt;&lt;br /&gt;Join Date: May 2004Local Time is: 12:33 PM Location: Upstate South CarolinaPosts: 1,181 Here's a link to th 1746-NT4 user's manual, it has examples and is pretty straight forward.&lt;a href="http://literature.rockwellautomatio...um007_-en-p.pdf/"&gt;http://literature.rockwellautomatio...um007_-en-p.pdf/&lt;/a&gt;&lt;br /&gt;You have to configure the card for the type of thermocouple, and for degrees F or C.

I have downloaded a few PDFs regarding the BTW and BTR commands but I am not clear completely as how to use these for more than one anlog input.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;let’s proceed along those lines ... you can always use the SLC-500 system later ... below is an example of the 1771-IXE module’s configuration screen ... you’ll find this under the IO Configuration feature in the RSLogix5 software - after you “insert” the module in the proper slot on the “display chassis” screen ...&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;The example shows a 1771-IXE/C module which I often use in the lab for student exercises ... presently it has one J-type thermocouple connected to Channel 1 ... you can see the room temperature (71 degrees F.) indicated by a red arrow ...&lt;br /&gt;note (as highlighted) that the data from the thermocouple at Channel 1 is located at N10:3 ... data from all of the other seven channels is presently reading “2192” because no thermocouples are connected there ... if there were thermocouples connected to those channels, then their readings would be located at N10:4 through N10:10 ... I know that this particular example is working because I can hold the tip of the thermocouple between my fingers and watch the temperature indication rise on the screen ...&lt;br /&gt;&lt;br /&gt;Another interesting note: if you’ll press the handy “Insert Ladder Rungs” button on this screen, then RSLogix5 will actually write the ladder logic rungs for you ... I’ve attached a couple of files that you might find helpful ... if you have any further specific questions, then it would be a good idea to list ALL of the hardware and software that you have available ... as you can see, we can offer you very detailed help with your project - but only if we know enough about your hardware and software to give specific answers ... good luck ...Attached Files &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;TRYIXE.pdf (68.8 KB, 7 views) &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;TRYIXE.ZIP (25.9 KB, 6 views) __________________&lt;br /&gt;Best regards,&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;Ron&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;&lt;a href="http://www.ind-info.com/"&gt;http://www.ind-info.com/&lt;/a&gt; &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;&lt;br /&gt;--------------------------------------------------------------------------------&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3333ff;"&gt;Last edited by Ron Beaufort : July 18th, 2005 at 12:16 PM.

However, the SLC and associated RSLogix software make the RIO link set up a snap. Just be sure you look over the RIO cable requirements and terminate it correctly and you should have no problems. Just remember that the 1771 I/O rack will show up as just I/O in the SLC data table and it is up to you to know which ones are for what. It is really easy since the 1771 rack will be labeled based on where your RIO Scanner module is in the SLC rack. It is a great plan, go for it.&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;Thunder is good, thunder is impressive;but it is lightning that does the work!Mark Twain-8/28/1908 randylud View Public Profile Send a private message to randylud Visit randylud's homepage!

The only thing is I had no 32 bit cards--this means 1/2 slot addressing--which the chassis is set up for already. But I don't know how the 1747 scanner handles it, for sure.&lt;br /&gt;6 * 32 point DC input cards 1771-IBN&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;5 * 32 point DC output cards 1771-OBN&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;3 * 16 point 110v ac output cards 1771-OAD&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;That's 14 slots but 25 groups or words. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;The 1747-sn alloows 32 so I think your OK.&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;I had 2 16 slot racks so each one was actually configured as 2 logical racks--single slot addressing--your one 16 slot rack will be configured as 4 logical racks---1/2 slot addressing.&lt;br /&gt;&lt;/p&gt;&lt;/span&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;The tricky thing here is that you'll have 32 words of data all referenced to the slot of the SLC where the SN module is--I:1.0/0 thru I:1.31/15. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;In your case if there's a 32 bit card in your first slot, it will be words 0 and 1 in the SN slot. Point is, it's not as easy to look at the SLC address on a printout and readily find the physical I/O ppoint in the rack--because you lose the slot/bit info to the word/bit stuff.&lt;br /&gt;&lt;/p&gt;&lt;/span&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;Another thing--&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;I:1.0/08 in the SLC equates to I:0/10 at the physical input point. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;The 1771 cards are octal--the SLC I/O table is decimal.&lt;br /&gt;&lt;/p&gt;&lt;/span&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;If you would assign symbols to the SLC bits that relate to the physical I/O and it would be helpful. ie I_0_10.&lt;br /&gt;Good luck,have fun &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;The Big Cheese john paley View Public Profile Send a private message to john paley Find More Posts by john paley Add john paley to Your Buddy List&lt;br /&gt;October 2nd, 2003, 08:28 AM #9 PhilipW Member&lt;br /&gt;&lt;br /&gt;Join Date: Dec 2002Local Time is: 05:56 PM Location: Wellington, New Zealand.

All the above is true, however I do recall one oddity that caught me unawares.&lt;br /&gt;It turned out that the SLC scanned a lot faster than the PLC2 and in the program I converted this caused a very obscure bug. I can't recall the exact details of the bug, but in general you may just want to keep this thought tucked away in the back of your mind as a possible source of problems.&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;Overall the conversion is a bit of a b**** and I wouldn't volunteer to do it again. Nothing converts smoothly from octal to decimal and either you finish up by converting most of the code literally into less than elegant SLC program, or you finish up re-writing the whole damm thing from scratch.&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;Complacency is not an enduring condition.&lt;br /&gt;--------------------------------------------------------------------------------&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;Last edited by PhilipW : October 2nd, 2003 at 08:32 AM.&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;PhilipW View Public Profile Send a private message to PhilipW Visit PhilipW's homepage!

It seems that there was an issue between series a and series b racks. I think the a's won't work with 16 point i/o but the b's will. Check with AB and your specific rack catalog #. Doesn't sound like your problem exactly, but you never know with the old stuff.&lt;br /&gt;Were you using 32 point cards with the PLC 2 ????&lt;br /&gt;Do the rack dip starting rack/group match the 1747-sn config???&lt;br /&gt;--------------------------------------------------------------------------------&lt;br /&gt;Ken RoachDecember 8th, 2003, 04:01 PM&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;If it's really a "1771-A4" chassis, it is only going to support 8-point I/O modules, no matter what kind of adapter you put into it.&lt;br /&gt;You're going to need a 1771-A4B chassis (in production since 1985 !).&lt;br /&gt;There is an A-B technote, # A16647, that goes over all the technical considerations when re-using PLC-2 hardware with newer controllers.&lt;br /&gt;--------------------------------------------------------------------------------&lt;br /&gt;JezzDecember 8th, 2003, 04:08 PM&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;sorry Ken it is a 1771-A4B chassis&lt;br /&gt;--------------------------------------------------------------------------------&lt;br /&gt;Ken RoachDecember 8th, 2003, 05:17 PM&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;Okay, it's time to get dirty with the DIP switches.&lt;br /&gt;Post the DIP switch settings you have for the 1771-A4B chassis, the 1771-ASB/E adapter, and the settings you've made in RSLogix 500 advanced I/O configuration for the G-file of the 1747-SN, which sets up the various I/O addresses you want the scanner to scan.&lt;br /&gt;JezzDecember 9th, 2003, 10:19 AMHere You go Ken&lt;br /&gt;Right the Chassis first&lt;br /&gt;It contains&lt;br /&gt;6 * 32 point DC input cards 1771-IBN&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;5 * 32 point DC output cards 1771-OBN&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;3 * 16 point 110v ac output cards 1771-OAD&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;In These positions&lt;br /&gt;slots 1 to 6 are 32 point Inputs Slot 7 is 32 point output&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="color:#3366ff;"&gt;Slot 8 is emptySlot 9 to 12 are 32 point outputsslots 13 to 15 are 16 point outputs&lt;br /&gt;1 -

Además se le agregó un pequeño rack de la familia 1794. O sea que quedó constituído un sistema con SLC500 5/05 y 4 racks remotos todo esto a través de RIO.&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="font-family:verdana;color:#ff0000;"&gt;Para lograr esto tube que sortear varios inconvenientes que quisiera compartir. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="font-family:verdana;color:#ff0000;"&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="font-family:verdana;color:#ff0000;"&gt;Me encontré que para poder mantener una buena comunicación entre todos los ASB (que ahora son 4 y no 1 como en el diseño previo) y el módulo scanner 1747-SN/B, fue conveniente setear a 57600 baudios.&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="font-family:verdana;color:#ff0000;"&gt;Sin embargo, en uno de los racks que pasó de ser local en PLC-2 a ser remoto para el SLC-500 existía un módulo 1771-IKC que es un contador de alta velocidad con un encoder AB open collector, por causa de la velocidad de actualización de la lectura en formato BCD tube que cambiarlo por un módulo 1746-HSC en el rack lócal.&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span style="font-family:verdana;color:#ff0000;"&gt;Gabriel.&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;a href="mailto:gepraa@yahoo.com.ar"&gt;gepraa@yahoo.com.ar&lt;/a&gt;&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/36600673-3475224271231450409?l=gepraa.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/3475224271231450409'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/36600673/posts/default/3475224271231450409'/><link rel='alternate' type='text/html' href='http://gepraa.blogspot.com/2006/11/revamping-de-plc-2.html' title='Up-grade de PLC-2 AB'/><author><name>Gabriel Edgardo</name><uri>http://www.blogger.com/profile/15737621644756089532</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='29' src='http://2.bp.blogspot.com/_AVo6d3JS8vM/SJnpz2Bb2xI/AAAAAAAAAJo/Ehd9P9DGx7w/s1600-R/P1010116.JPG'/></author></entry><entry><id>tag:blogger.com,1999:blog-36600673.post-6541827303431600886</id><published>2006-11-02T13:08:00.005-03:00</published><updated>2008-09-20T10:56:58.883-03:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Experiencias'/><title type='text'>Proyectos concluidos</title><content type='html'>&lt;p&gt;&lt;strong&gt;&lt;span style="color:#ff0000;"&gt;&lt;/p&gt;&lt;blockquote&gt;&lt;strong&gt;&lt;span style="color:#ff0000;"&gt;&lt;/span&gt;&lt;/strong&gt;&lt;/blockquote&gt;&lt;blockquote&gt;&lt;/blockquote&gt;&lt;blockquote&gt;&lt;/blockquote&gt;&lt;blockquote&gt;&lt;/blockquote&gt;&lt;p align="center"&gt; &lt;/p&gt;&lt;p align="center"&gt;Desarrollo del software un sistema de acarreo Over Head por lotes para cubiertas crudas con 6 elevadores, 28 cintas transportadoras y 9 derivadores.

Objetivos. &lt;/span&gt;&lt;/em&gt;&lt;/strong&gt;&lt;br /&gt;&lt;br /&gt;El objetivo principal es el de establecer la unión eléctrica, óptica, telefónica, por red o&lt;br /&gt;por radio de los equipos electrónicos instalados en toda el área industrial para obtener de&lt;br /&gt;ellos los datos que componen la información de todos los procesos que se ejecutan en&lt;br /&gt;tiempo real. Dichos datos podrán ser utilizados para componer sistemas visuales de&lt;br /&gt;información a diferentes niveles, como ser:&lt;br /&gt;· Interfaz entre equipos.&lt;br /&gt;· Interfaz hombre máquina.&lt;br /&gt;· Información global de planta.&lt;br /&gt;· Sistemas de gestión. &lt;/div&gt;&lt;br /&gt;&lt;div&gt;&lt;br /&gt;&lt;strong&gt;&lt;em&gt;&lt;span style="color:#339999;"&gt;B.

Este aspecto resulta entonces ser&lt;br /&gt;también de vital interés.&lt;br /&gt;&lt;br /&gt;&lt;/div&gt;&lt;br /&gt;&lt;div&gt;&lt;strong&gt;&lt;em&gt;&lt;span style="color:#339999;"&gt;C.

También se aplicaría a procesos que, por su&lt;br /&gt;naturaleza merecen ser tratados como un conjunto.&lt;br /&gt;Es importante pensar cada uno de los esquemas presentados como unidades de&lt;br /&gt;conectividad. De ese modo se los podrá tratar por separado y podrán componer el sistema&lt;br /&gt;de información completa del área.&lt;br /&gt;Algunos de los esquemas presentados se plantearan como alternativas de los otros.&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;/div&gt;&lt;br /&gt;&lt;div&gt;&lt;strong&gt;&lt;em&gt;&lt;span style="color:#339999;"&gt;D.
