可編程控制器的工作過程及FN2N PLC的組成

PLC雖具有微機的許多特點，但它的工作方式卻與微機有很大的不同。微機一般採用等待命令的工作方式，如常見的鍵盤掃描方式或I/O掃描方式，有鍵按下或I/O動作則轉入相應的子程序無鍵按下則繼續掃描。PLC則採用循環掃描工作方式，在PLC中，用戶程序按先後順序存放。

CPU從第一條指令開始執行程序，直至遇到結束符後又返回第一條。如此周而復始不斷循環。這種工作方式是在係統軟件控制下，順次掃描各輸入點的狀態，按用戶程序進行運算處理，然後順序向輸出點發出相應的控制信號。整個工作過程可分為五個階段：自診斷，與編程器等的通信，輸入採樣，用戶程序執行，輸出刷新。
