描述

從PLC控制系統(tǒng)與電器控制系統(tǒng)比較可知，PLC的用戶程序（軟件）代替了繼電器控制電路（硬件）。因此，對于使用者來說，可以將PLC等效成是許許多多各種各樣的“軟繼電器”和“軟接線”的集合，而用戶程序就是用“軟接線”將“軟繼電器”及其“觸點”按一定要求連接起來的“控制電路”。為了更好的理解這種等效關(guān)系，下面通過一個例子來說明。如圖1所示為三相異步電動機(jī)單向起動運行的電器控制系統(tǒng)。其中，由輸入設(shè)備SB1、SB2、FR的觸點構(gòu)成系統(tǒng)的輸入部分，由輸出設(shè)備KM構(gòu)成系統(tǒng)的輸出部分。
