描述

CPU是PLC的核心組成部分，與通用微機的CPU一樣，它在PLC系統(tǒng)中的作用類似于人體的神經(jīng)中樞，故稱為“電腦”。其功能是：

a、按PLC中系統(tǒng)程序賦予的功能，接收并存儲從編程器輸入的用戶程序和數(shù)據(jù)。

b、用掃描方式接收現(xiàn)場輸入裝置的狀態(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)部電路的工作狀態(tài)和編程過程中的語法錯誤。

d、在PLC進入運行狀態(tài)后，從存儲器中逐條讀取用戶程序，經(jīng)過命令解釋后按指令規(guī)定的任務(wù)，產(chǎn)生相應(yīng)的信號，去啟閉有關(guān)控制門電路。分時分渠道地去執(zhí)行數(shù)據(jù)的存取、傳送、組合、比較和變換等操作，完成用戶程序中規(guī)定的邏輯式算術(shù)運算等任務(wù)。根據(jù)運算結(jié)果，更新有關(guān)標(biāo)志位的狀態(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，實現(xiàn)輸出控制、制表、打印式數(shù)據(jù)通訊等。

PLC常用的CPU主要采用通用微處理器、單片機或雙極型位片式微處理器。通用的微處理器常用的是8位機和16位機，如Z80A、8085、8086、6502、M6800、M6809、M68000等。單片機常用的有8039、8049、8031、8051等。雙極型位片式微處理器常用的有AMD2900、AMD2903等。
