Abstract

"SISTEMA DE DIAGNóSTICO PARA UTILIZAçãO EM UMA REDE DE CONTROLE DE PROCESSO, BLOCO DE FUNçãO DE DIAGNóSTICO, E, PROCESSO PARA REALIZAçãO DE DIAGNóSTICOS EM UMA REDE DE CONTROLE DE PROCESSO" Trata-se de um sistema de diagnóstico adaptado para realização de diagnóstico de dispositivos e de processo numa rede de controle de processo que possui uma pluralidade de dispositivos de controle de processo interligados de forma passível de comunicação através de um barramento, em que cada um dos dispositivos é capaz de realizar uma função de controle de processo e comunicar através do barramento utilizando comunicações periódicas programadas. O sistema de diagnóstico é disposto num primeiro dos dispositivos e inclui um gerador de sinais que produz um sinal de controle de diagnóstico, um dispositivo comunicador configurado para fornecer o sinal de controle de diagnóstico para um segundo dos dispositivos utilizando comunicações periódicas programadas, e um receptor de sinais de saída adaptado para receber um sinal de saída desenvolvido pelo segundo dispositivo em resposta ao sinal de controle de diagnóstico. O sistema de diagnóstico pode utilizar o sinal de saída recebido para realizar diagnósticos ou pode enviar este sinal para uma central para análise de diagnóstico.
