為了完成控制策略，為了替代繼電器，使用戶等完成類似繼電器線路的控制系統(tǒng)梯形圖，而編制了一套控制算法功能塊(或子程序)，稱為指令系統(tǒng)，固化在存貯器ROM中，用戶在編制應(yīng)用程序時可以調(diào)用。指令系統(tǒng)大致可以分為兩類，即基本指令和擴(kuò)展指令。細(xì)分一般PLC的指令系統(tǒng)有:基本指令、定時器/計(jì)數(shù)器指令、移位指令、傳送指令、比較指令、轉(zhuǎn)換指令、BCD運(yùn)算指令、二進(jìn)制運(yùn)算指令、增量/減量指令、邏輯運(yùn)算指令、特殊運(yùn)算指令等，這些指令多是類似匯編語言。另外PLC還提高了充足的計(jì)時器、計(jì)數(shù)器、內(nèi)部繼電器、寄存器及存貯區(qū)等內(nèi)部資源，為編程帶來極大方便。
