Abstract
LA PRESENTE INVENCION SE REFIERE A UN SISTEMA DE AUTOMATISMO PROTEGIDO CONSTITUIDO POR DOS AUTOMATAS (PLC-A, PLC_B) EQUIPADOS POR UNA PARTE DE ACOPLADORES DE REDUNDANCIA (CR-A Y CR-B) CONECTADOS UNO A OTRO POR UNA CONEXION INTERCADENA (LIC) Y POR OTRA PARTE ACOPLADORES ANALOGICOS (CA-A Y CA-B) QUE RECIBEN CADA UNO UNA DE LAS DOS VIAS DE ENTRADA (A, B) DE UNA MISMA SEÑAL ANALOGICA PROPORCIONADA POR UN DETECTOR O APARATO SIMILAR, Y CARACTERIZADO POR EL HECHO DE QUE CONSISTE EN REALIZAR UN MUESTREO FISICO DE LAS SEÑALES DE ENTRADA EN LOS ACOPLADORES ANALOGICOS (CA-A, CA-B), EN INTERCAMBIARLOS CON LA MEMORIA (MA) DE LOS AUTOMATAS, EN TOMAR, EN LA MEMORIA (MA), LOS VALORES MUESTREADOS A LA FRECUENCIA DE MUESTREO DE AUTOMATA Y EN REALIZAR UN ANALISIS DE CONCORDANCIA DE DICHOS VALORES MUESTREADOS DE MANERA QUE DETECTE SI LAS DIFERENCIAS SON DEBIDAS AL MECANISMOS DE ADQUISICION DE LOS DATOS EN CUYO CASO LAS ENTRADAS SON CONCORDANTES O BIEN CON UNA VERDADERA DIFERENCIA EN LAS ENTRADAS FISICAS EN CUYO CASO LAS ENTRADAS SON DISCORDANTES.
