Abstract

UN SISTEMA BUSSY CON UN ACUMULADOR (MEM) SIRVE COMO CAMPO MULTIPORT (MUPO). MEDIANTE LA INTERVENCION ALTERNA (ZUG) SOBRE ESTE ACUMULADOR (MEM) SE TRANSMITEN LOS DATOS DE UNA UNIDAD DE TRANSMISION DE DATOS Y DE ELABORACION (DAT) HACIA OTRAS UNIDADES. AQUEL QUE PUEDA INTERVENIR SOBRE EL ACUMULADOR (MEM) ESTABLECERA UN CONTROL DE PRIORIDADES (PRIO). LA LISTA PRIORITARIA PLIS ENVIA AL CONTROL DE PRIORIDAD (PRIO) LAS INFORMACIONES NECESARIAS. LA LISTA DE PRIORIDAD (PLIS) SE ACTUALIZA PARA CADA INTERVENCION (ZUG), DE TAL FORMA QUE CADA UNIDAD CONECTADA (DAT) PUEDA TENER LA MAXIMA PRIORIDAD. LA DECISION DE INTERVENCION SE TOMA DENTRO DE UN PERIODO DE CADENCIA.
