Abstract

PROCESO DE SINCRONIZACION PARA UN SISTEMA (1) DE AUTOMATIZACION DE CONSTRUCCION REDUNDANTE, QUE SE COMPONE DE AL MENOS DOS SISTEMAS (2,2'') PARCIALES QUE, PARA CONTROLAR UN PROCESO, REALIZAN SECUENCIAS FUNCIONALMENTE IDENTICAS DE ORDENES (MP) DE MAQUINA, QUE TIENEN INSTRUCCIONES (IA) DE INCREMENTACION EN POSICIONES CORRESPONDIENTES MUTUAMENTE PARA INCREMENTAR UN CONTADOR (SZ, SZ'') DE SINCRONIZACION. LA SINCRONIZACION TIENE LUGAR UTILIZANDO EL VALOR DE UN CONTADOR (SZ, SZ'') DE SINCRONIZACION AL MENOS CUANDO UN SISTEMA (2,2'') PARCIAL REGISTRA UN ACONTECIMIENTO (11) ESPECIAL. PARA ESTE EFECTO SE DETERMINA UN VALOR (SZZ) OBJETIVO DE CONTADOR DE SINCRONIZACION DE TAL MODO QUE LOS SISTEMAS (2,2'') PARCIALES INTERRUMPEN LA EJECUCION DE LA SECUENCIA DE ORDENES (MP) DE MAQUINA, EN LOS CUALES LOS VALORES Y EL CONTADO (SZ, SZ'') DE SINCRONIZACION ALCANZAN EL VALOR OBJETIVO (SZ) DE CONTADOR DE SINCRONIZACION.
