Abstract

PARA UNA ENTRADA/SALIDA COMPUTERIZADA DE SEÑALIZACIONES Y COMANDOS, SE PREVEEN UNA SERIE DE MODULOS DE ENTRADA (OE1 A OE4) Y DE MODULOS DE SALIDA. ESTOS SON ACTIVADOS POR UN SISTEMA COMPUTERIZADO (R) A TRAVES DE UN PRIMER REGISTRO (R1. 1), CONDUCIENDOSE LAS SEÑALIZACIONES SUCESIVAS DE UN PROCESO AL SISTEMA COMPUTERIZADO A TRAVES DE UNA LINEA DE DATOS (D1) COMUN O EMITIENDOSE UN COMANDO A UN PROCESO. EL POTENCIAL QUE SE ACUMULA EN LA SALIDA DEL PRIMER REGISTRO (R1.1) ES REENVIADO AL SISTEMA COMPUTERIZADO A TRAVES DE UN SEGUNDO REGISTRO (R2.1). EL SISTEMA RECONOCE A QUE MODULO HAY QUE ASOCIAR LA SEÑALIZACION QUE SE ENCUENTRA EN LA LINEA DE DATOS (D1). EN UN FUNCIONAMIENTO DE CONTROL, LOS MODULOS SE CONECTAN-DESCONECTAN O SE CONECTAN Y SE DESCONECTAN SECUENCIALMENTE. LAS SEÑALIZACIONES DE LOS ESTADOS DE LOS MODULOS QUE SE OBTIENEN, SE INTRODUCEN A TRAVES DE UNA LINEA ESPECIAL DE DATOS (DP1) Y SE ANALIZAN. ESTE ESQUEMA DE CONEXIONES ES ESPECIALMENTE APTO PARA PEQUEÑAS INSTALACIONES COMPUTERIZADAS, CUYA CARGA BASE DEL ORDENADOR PUEDE SER RELATIVAMENTE ALTA PARA EJECUTAR LAS RUTINAS DE CONTROL, PERO QUE TIENEN UN INTERES ESPECIAL EN MINIMIZAR EL DESPLIEGUE DE HARDWARE.
