當(dāng)PLC運(yùn)行時(shí)，是通過執(zhí)行反映控制要求的用戶程序來完成控制任務(wù)的，需要執(zhí)行眾多的操作，但CPU不可能同時(shí)去執(zhí)行多個(gè)操作，它只能按分時(shí)操作（串行工作）方式，每一次執(zhí)行一個(gè)操作，按順序逐個(gè)執(zhí)行。由于CPU的運(yùn)算處理速度很快，所以從宏觀上來看，PLC外部出現(xiàn)的結(jié)果似乎是同時(shí)（并行）完成的。這種串行工作過程稱為PLC的掃描工作方式。

用掃描工作方式執(zhí)行用戶程序時(shí)，掃描是從條程序開始，在無中斷或跳轉(zhuǎn)控制的情況下，按程序存儲(chǔ)順序的先后，逐條執(zhí)行用戶程序，直到程序結(jié)束。然后再從頭開始掃描執(zhí)行，周而復(fù)始重復(fù)運(yùn)行。
