對于簡單故障可根據(jù)程序通過PLC的狀態(tài)顯示信息,監(jiān)視相關輸人、輸出及標志位的狀態(tài),跟蹤程序的運行,而復雜的故障必須使用編程器來跟蹤程序的運行。如某水泵不工作,檢查發(fā)現(xiàn)對應的PLC輸出端口為0,于是通過查看程序發(fā)現(xiàn)熱水泵還受到水溫的控制,水溫不夠PLC就沒有輸出,把水溫升高后故障排除。
邏輯設計法是利用邏輯代數(shù)來進行電路設計,從生產(chǎn)機械的拖動要求和工藝要求出發(fā),將控制電路中的接觸器、繼電器線圈的通電與斷電,觸點的閉合與斷開,主令電器的接通與斷開看成邏輯變量,根據(jù)控制要求將它們之間的關系用邏輯關系式來表達,然后再化簡,做出相應的電路圖

這兩類控制設備在各領域的自動化中扮演了不可缺少的角色。圖1給出了某自來水廠工業(yè)控制系統(tǒng)的典型結構圖,其中采用了PLC作為I/O控制站、工控機作為監(jiān)控機。
瞬時過電流保護。由于逆變器負載側短路等,流過逆變器器件的電流達到異常值(超過容許值)時,瞬時停止逆變器運轉,切斷電流。變流器的輸出電流達到異常值,也同樣停止逆變器運轉。
