PLC的基本工作方式是順序執(zhí)行用戶(hù)程序，每一時(shí)鐘周期執(zhí)行一條指令。對(duì)用戶(hù)程序的執(zhí)行一般有循環(huán)掃描和定時(shí)掃描兩種，掃描過(guò)程分為三個(gè)階段，即輸入采樣階段、程序執(zhí)行階段和輸出刷新階段，如圖1所示。
（1）輸入采樣階段。PLC在輸入采樣階段以掃描方式順序讀人所有輸入端子的狀態(tài)，存人輸人寄存器，接著轉(zhuǎn)入程序執(zhí)行階段。
（2）程序執(zhí)行階段。PLC在程序執(zhí)行階段中順序?qū)γ織l指令進(jìn)行掃描。先從輸人寄存器讀人所有輸入端子的狀態(tài)。
圖 PLC程序執(zhí)行過(guò)程
（3）輸出刷新階段。所有指令執(zhí)行完畢后，將輸出寄存器中所有的輸出狀態(tài)送到輸出電路，成為PLC的實(shí)際輸出。
PLC執(zhí)行完上述的三個(gè)階段稱(chēng)為一個(gè)掃描周期。
