Abstract
UNA DISPOSICION DE DATOS DE COMUNICACION PARA UN SISTEMA PROCESADOR DE CONTROL QUE TENGA UN NUMERO DE ESTACIONES (12, 32) QUE PUEDE ENVIAR Y RECIBIR DATOS DE CONTROL, INCLUYE UN PROCESADOR DE COMUNICACIONES EN CADA ESTACION EFECTIVA PARA CONTROLAR EL FLUJO DE DATOS DE CONTROL SOBRE UN BUS DE COMUNICACIONES EN SERIE. EL PROCESADOR DE COMUNICACIONES (66) ESTA ACOPLADO A UN APARATO CON MEMORIA DUAL (68) JUNTO CON UN PROCESADOR FUNCIONAL (70) QUE SE UTILIZA PARA LLEVAR A CABO LAS OPERACIONES ACTUALES DEL PROCESO. EL PROCESADOR DE CONTROL DE COMUNICACIONES SIRVE ADEMAS PARA ENSAMBLAR FRAGMENTOS DE DATOS DE CONTROL (FIG. 4) DE ACUERDO CON UNA DISPOSICION PREDETERMINADA QUE DA UN TIEMPO DE PREFERENCIA A UNA PRIMERA CATEGORIA DE DATOS SOBRE UNA SEGUNDA CATEGORIA DE DATOS. EL FRAGMENTO ENSAMBLADO DE DATOS DE CONTROL INCLUIRA PUES LA PRIMERA CATEGORIA DE DATOS Y, CON EL TIEMPO QUE RESTE DE UN TIEMPO LIMITE, SE INCLUIRA UNA PORCION DE LA SEGUNDA CATEGORIA DE DATOS.
