PLC的結構及各部分的作用
、主機
主機部分包括中央處理器（CPU）、系統程序存儲器和用戶程序及數據存儲器。CPU是PLC的核心，它用以運行用戶程序、監控輸入/輸出接口狀態、作出邏輯判斷和進行數據處理，即讀取輸入變量、完成用戶指令規定的各種操作，將結果送到輸出端，并響應外部設備（如電腦、打印機等）的請求以及進行各種內部判斷等。PLC的內部存儲器有兩類，一類是系統程序存儲器，主要存放系統管理和監控程序及對用戶程序作編譯處理的程序，系統程序已由廠家固定，用戶不能更改；另一類是用戶程序及數據存儲器，主要存放用戶編制的應用程序及各種暫存數據和中間結果。
2、輸入/輸出（I/O）接口
I/O接口是PLC與輸入/輸出設備連接的部件。輸入接口接受輸入設備（如按鈕、傳感器、觸點、行程開關等）的控制信號。輸出接口是將主機經處理后的結果通過功放電路去驅動輸出設備（如接觸器、電磁閥、指示燈等）。I/O接口一般采用光電耦合電路，以減少電磁干擾，從而提高了可靠性。I/O點數即輸入/輸出端子數是PLC的一項主要技術指標，通常小型機有幾十個點，中型機有幾百個點，大型機將超過千點。
3、電源
圖中電源是指為CPU、存儲器、I/O接口等內部電子電路工作所配置的直流開關穩壓電源，通常也為輸入設備提供直流電源。
4、編程
編程是PLC利用外部設備，用戶用來輸入、檢查、修改、調試程序或監示PLC的工作情況。通過專用的PC/PPI電纜線將PLC與電腦聯接，并利用專用的軟件進行電腦編程和監控。
5、輸入/輸出擴展單元
I/O擴展接口用于將擴充外部輸入/輸出端子數的擴展單元與基本單元（即主機）連接在一起。
