PLC內(nèi)部工作方式一般是采用循環(huán)掃描工作方式，在一些大、中型的PLC中增加了中斷工作方式。當(dāng)用戶將用戶程序調(diào)試完成后，通過編程器將其程序?qū)懭隤LC存儲器中，同時將現(xiàn)場的輸入信號和被控制的執(zhí)行元件相應(yīng)的連接在輸入模塊的輸入端和輸出模塊的輸出端，接著將PLC工作方式選擇為運(yùn)行工作方式，后面的工作就由PLC根據(jù)用戶程序去完成，右圖是PLC執(zhí)行過程框圖。PLC在工作過程中，主要完成六個模塊的處理
對于工控機(jī)，能夠簡單操作是好的，這也將成為未來的發(fā)展方向，簡易操作可以改善人機(jī)接口，簡化編程、操作面板使用符號鍵，盡量采用對話方式等，以方便用戶使用。
