外部的開關(guān)信號、模擬信號以及各種傳感器檢測信號作為PLC的輸入變量，它們經(jīng)PLC的輸入端子進(jìn)入PLC的輸入存儲器，收集和暫存被控對象實(shí)際運(yùn)行的狀態(tài)信息和數(shù)據(jù)；經(jīng)PLC內(nèi)部運(yùn)算與處理后，按被控對象實(shí)際動作要求產(chǎn)生輸出結(jié)果；輸出結(jié)果送到輸出端子作為輸出變量，驅(qū)動執(zhí)行機(jī)構(gòu)。PLC的各部分協(xié)調(diào)*地實(shí)現(xiàn)對現(xiàn)場設(shè)備的控制。
（1）*處理器CPU
CPU的主要作用是解釋并執(zhí)行用戶及系統(tǒng)程序，通過運(yùn)行用戶及系統(tǒng)程序完成所有控制、處理、通信以及所賦予的其它功能，控制整個(gè)系統(tǒng)協(xié)調(diào)*地工作。常用的CPU主要有通用微處理器、單片機(jī)和雙極型位片機(jī)。
（2）存儲器模塊

隨機(jī)存取存儲器RAM用于存儲PLC內(nèi)部的輸入、輸出信息，并存儲內(nèi)部繼電器（軟繼電器）、移位寄存器、數(shù)據(jù)寄存器、定時(shí)器／計(jì)數(shù)器以及累加器等的工作狀態(tài)，還可存儲用戶正在調(diào)試和修改的程序以及各種暫存的數(shù)據(jù)、中間變量等。
只讀存儲器ROM用于存儲系統(tǒng)程序。可擦除可編程序的只讀存儲器EPROM主要用來存放PLC的操作系統(tǒng)和監(jiān)控程序，如果用戶程序已*調(diào)試好，也可將程序固化在EPROM中。
（3）輸入輸出模塊
可編程序控制器是一種工業(yè)控制計(jì)算機(jī)系統(tǒng)，它的控制對象是工業(yè)生產(chǎn)過程，與DCS相似，它與工業(yè)生產(chǎn)過程的也是通過輸入輸出接口模塊（I/O）實(shí)現(xiàn)的。I/O模塊是可編程序控制器與生產(chǎn)過程相的橋梁。
