PLC控制系統(tǒng)主要由輸入部分、CPU、采樣部分、輸出控制和通訊部分組成,如圖1所示。輸入部分包括控制面板和輸入模板;采樣部分包括采樣控制模板、AD轉(zhuǎn)換模板和傳感器;CPU作為系統(tǒng)的核心,完成接收數(shù)據(jù),處理數(shù)據(jù),輸出控制信號(hào);輸出部分有的系統(tǒng)用到DA模板,將輸出信號(hào)轉(zhuǎn)換為模擬量信號(hào),經(jīng)過功放驅(qū)動(dòng)執(zhí)行器;大多數(shù)系統(tǒng)直接將輸出信號(hào)給輸出模板,由輸出模板驅(qū)動(dòng)執(zhí)行器工作;通訊部分由通訊模板和上位機(jī)組成。
因?yàn)镻LC本身的故障可能性極小,系統(tǒng)的故障主要來自外圍的元部件,所以它的故障可分為如下幾種:

?。?)輸入故障,即操作人員的操作失誤;
■傳感器故障;
■執(zhí)行器故障;
■PLC軟件故障
這些故障,都可以用合適的故障診斷方法進(jìn)行分析和用軟件進(jìn)行實(shí)時(shí)監(jiān)測(cè),對(duì)故障進(jìn)行預(yù)報(bào)和處理。
