可編程控制器的構(gòu)成框圖和盤(pán)算機(jī)是一樣的，都由中央處置處罰器（CPU）、存貯器和輸入/輸出接口等構(gòu)成。因此，從硬件布局來(lái)說(shuō)，可編程控制器現(xiàn)實(shí)上便是盤(pán)算機(jī)，圖1是其硬件體系的簡(jiǎn)化框圖。從圖中可以看出PLC內(nèi)部重要部件有:
（1）CPU（Central Process Unit）
CPU是PLC的核心構(gòu)成部分，與通用微機(jī)的CPU一樣，它在PLC體系中的作用雷同于人體的神經(jīng)中樞，故稱(chēng)為“電腦”。其功效是：
a、按PLC中體系步伐付與的功效，吸收并存儲(chǔ)從編程器輸入的用戶(hù)步伐和數(shù)據(jù)。
b、用掃描方法吸收現(xiàn)場(chǎng)輸入裝置的狀態(tài)式數(shù)據(jù)，并存入映象寄存器或數(shù)據(jù)寄存器中。
c、診斷電源、PLC內(nèi)部電路的事情狀態(tài)和編程歷程中的語(yǔ)法錯(cuò)誤。
d、在PLC進(jìn)入運(yùn)行狀態(tài)后，從存儲(chǔ)器中逐條讀取用戶(hù)步伐，顛末下令表明后按指令劃定的使命，產(chǎn)生相應(yīng)的信號(hào)，去啟閉有關(guān)控制門(mén)電路。分時(shí)分渠道地去實(shí)行數(shù)據(jù)的存取、傳送、組合、比力和變更等操縱，完成用戶(hù)步伐中劃定的邏輯式算術(shù)運(yùn)算等使命。憑據(jù)運(yùn)算結(jié)果，更新有關(guān)標(biāo)記位的狀態(tài)和輸出映象寄存器的內(nèi)容，再由輸出映象寄存器的位狀態(tài)式數(shù)據(jù)寄存器的有關(guān)內(nèi)容，實(shí)現(xiàn)輸出控制、制表、打印式數(shù)據(jù)通訊等。
PLC常用的CPU重要接納通用微處置處罰器、單片機(jī)或雙極型位片衰落處置處罰器。通用的微處置處罰器常用的是8位機(jī)和16位機(jī)，如Z80A、8085、8086、6502、M6800、M6809、M68000等。單片機(jī)常用的有8039、8049、8031、8051等。雙極型位片衰落處置處罰器常用的有AMD2900、AMD2903等。
