4)中央處理器CPU將指令逐條調出並執行,以對輸人和原輸出狀態(這些狀態統稱為數據)進行“處理”,即按程序對數據進行邏輯、算術運算,再將正確的結果送到輸出狀態寄存器中,這就是程序執行階段。
5)當所有的指令執行完畢時,集中把輸出狀態寄存器的狀態通過輸出部件轉換成被控設備所能接受的電壓或電流信號,以驅動被控設備,這就是輸出刷新階段。
PLC經過這五個階段的工作過程,稱為一個掃描周期。完成一個周期後,又重新執行上述過程,掃描周而復始地進行。掃描周期是PLC的重要指標之一,在不考慮第二個因素(與編程器等通信)時,掃描周期T為:
T=(讀入一點時間×輸入點數)+(運算速度×程序步數)+(輸出一點時間×輸出點數)十故障診斷時間
