Abstract
Un método de resoluciones de señal de entrada en un sistema de control del proceso que tiene una pluralidad de computadoras de control del proceso activamente redundantes, donde cada una de las computadoras de control del proceso activamente redundantes recibe señales de entrada controlando, caracterizado por las etapas de: intercambiar mutuamente cuando menos un bloque de las señales de entrada correspondientes entre cada una de las computadoras de control del proceso activamente redundantes; seleccionar individualmente un valor de entrada en cada una de las computadoras de control del proceso activamente redundantes, para cada una de las señales de entrada intercambiadas; y registran una indicación en cada una de las computadoras de control del proceso activamente redundantes, para identificar cuál de las señales de entrada correspondientes se seleccionó, mediante esta computadora de control del proceso activamente redundante.
