 PLC典型開機流程

輸入刷新--再運行用戶程序--再輸出刷新--再輸入刷新--再運行用戶程序--再輸出刷新……永不停

止地循環反復地進行著。用PLC實現控制顯然是可能的。因為：有了輸入刷新，可把輸入電路監控得

到的輸入信息存入PLC的輸入映射區；經運行用戶程序，輸出映射區將得到變換后的信息；再經輸出

刷新，輸出鎖存器將反映輸出映射區的狀態，并通過輸出電路產生相應的輸出。又由于這個過程是

永不停止地循環反復地進行著，所以，輸出總是反映輸入的變化的。只是響應的時間上，略有滯后

。當然，這個滯后不宜太大，否則，所實現的控制不那么及時，也就失去控制的意義。

為此，PLC的工作速度要快。速度快、執行指令時間短，是PLC實現控制的基礎。事實上，它的速度

是很快的，執行一條指令，多的幾微秒、幾十微秒，少的才零點幾，或零點零幾微秒。而且這個速

度還在不斷提高中。

實際的PLC工作過程還要復雜些。除了I/O刷新及運行用戶程序，還要做些公共處理工作。
公共處理工作有：循環時間監控、外設服務及通訊處理等。監控循環時間的目的是避免"死循環"，

避免程序不能反復不斷地重復執行。辦法是用"看門狗"（Watchingdog）。只要循環超時，它可報警

，或作相應處理.外設服務是讓PLC可接受編程器對它的操作，或通過接口向輸出設備如打印機輸出

數據.通訊處理是實現PLC與PLC，或PLC與計算機，或PLC與其它工業控制裝置或智能部件間信息交換

的。這也是增強PLC控制能力的需要。

也就是說，實際的PLC工作過程總是：公共處理--I/O刷新--運行用戶程序--再公共處理--……反復

不停地重復著。
