*處理單元(CPU)是PLC的控制中樞。它按照PLC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PLC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PLC的可*性，近年來對大型PLC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。

PLC的工作原理
一. 掃描技術
當PLC投入運行后，其工作過程一般分為三個階段，即輸入采樣、用戶程序執行和輸出刷新三個階段。完成上述三個階段稱作一個掃描周期。在整個運行期間，PLC的CPU以一定的掃描速度重復執行上述三個階段。
(一) 輸入采樣階段
在輸入采樣階段，PLC以掃描方式依次地讀入所有輸入狀態和數據，并將它們存入I/O映象區中的相應得單元內。輸入采樣結束后，轉入用戶程序執行和輸出刷新階段。在這兩個階段中，即使輸入狀態和數據發生變化，I/O映象區中的相應單元的狀態和數據也不會改變。因此，如果輸入是脈沖信號，則該脈沖信號的寬度必須大于一個掃描周期，才能保證在任何情況下，該輸入均能被讀入。
