Abstract

Un sistema para establecer comunicación entre dos consolas centrales y una pluralidad de controladores locales, que comprende: una primera y una segunda consolas centrales para controlar la comunicación de dicho sistema, emitiendo dichos consolas mensajes de orden a dichos controladores y para recibir mensajes de respuesta de ellos, una primera vía de comunicación para transmitir mensajes, extendiendose dicha primera vía desde una consola central en serie a la totalidad de dicha pluralidad de controladores, una segunda vía de comunicación para transmitir mensajes, extendiéndose dicha primera vía desde una consolada central en serie a la totalidad de dicha pluralidad de controladores, una segunda vía de comunicación para transmitir mensajes, extendiendose dicha segunda vía desde una consola central en serie a la totalidad de dicha pluralidad de controladores, una segunda vía de comunicación para transmitir mensajes, extendiéndose dicha segunda vía desde la otra consola en serie a la totalidad de dicha pluralidad de controladores, estando conectado también los controladores que están conectados también los controladores que están conectados también los controladores que están conectados en lugares próximos a dicha primera consola a través de dicha primera vía de comunicación en lugares relativamente más alejado de dicho segundo controlador a través de dicha segunda vía de comunicación, estando interconectadas dichas consolas centrales de modo que cada una de las consolas es capaz de comunicar con cada controlador a través de cada una de las vías de comunicación.
