PLC 的掃描過程包含內(nèi)部處理、通信服務、輸入處理、程序執(zhí)行、輸出 處理 五個階段,這五個階段掃描一次所需的時間稱為掃描周期。
掃描周期與 CPU 運行速度、 PLC 硬件配置和用戶程序長短有關。

（1） 控制方法上:PLC 采用程序方式實現(xiàn)控制, 容易改變或增加控制要求, 且 PLC 的觸點無限;
（2）工作方式上:PLC 采用串行工作方式,提高系統(tǒng)的抗干擾能力;
（3）控制速度上:PLC 的觸點實際上是觸發(fā)器,指令執(zhí)行的時間在微秒級;
（4） 定時和計數(shù)上:PLC 采用半導體集成電路作定時器, 時鐘脈沖由晶振提供,延時 精度高,范圍寬。PLC 具有繼電器系統(tǒng)不具備的計數(shù)功能;
（5）可靠性和可維護性上:PLC 采用微電子技術(shù),可靠性高,所具有的自檢功能能 及時查出
