*處理單元（CPU）是可編程邏輯控制器的控制中樞。它按照可編程邏輯控制器系統程序賦予的功能接收并存儲從編程器鍵入的用戶程序和數據；檢查電源、存儲器、I/O以及警戒定時器的狀態，并能診斷用戶程序中的語法錯誤。當可編程邏輯控制器投入運行時，首先它以掃描的方式接收現場各輸入裝置的狀態和數據，并分別存入I/O映象區，然后從用戶程序存儲器中逐條讀取用戶程序，經過命令解釋后按指令的規定執行邏輯或算數運算的結果送入I/O映象區或數據寄存器內。等所有的用戶程序執行完畢之后，zui后將I/O映象區的各輸出狀態或輸出寄存器內的數據傳送到相應的輸出裝置，如此循環運行，直到停止運行。

　　為了進一步提高可編程邏輯控制器的可靠性，近年來對大型可編程邏輯控制器還采用雙CPU構成冗余系統，或采用三CPU的表決式系統。這樣，即使某個CPU出現故障，整個系統仍能正常運行。
