CPU（Central  Process  Unit）

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

a、按PLC中系統程序賦予的功能，接收并存儲從編程器輸入的用戶程序和數據。

b、用掃描方式接收現場輸入裝置的狀態式數據，并存入映象寄存器或數據寄存器中。

c、診斷電源、PLC內部電路的工作狀態和編程過程中的語法錯誤。

d、在PLC進入運行狀態后，從存儲器中逐條讀取用戶程序，經過命令解釋后按指令規定的任務，產生相應的信號，去啟閉有關控制門電路。分時分渠道地去執行數據的存取、傳送、組合、比較和變換等操作，完成用戶程序中規定的邏輯式算術運算等任務。根據運算結果，更新有關標志位的狀態和輸出映象寄存器的內容，再由輸出映象寄存器的位狀態式數據寄存器的有關內容，實現輸出控制、制表、打印式數據通訊等。

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。

①用通用微處理器作CPU

在低檔PLC中，用Z80A做CPU較為普遍，Z80A用于PLC有如下長處： Z80（或Z80A）CPU及其配套的芯片廉價、普及、通用，用這套芯片制成的PC，給維修及推廣普及帶來方便。Z80有獨立的輸入/輸出指令,而且指令格式較短，執行時間也較短，這樣有利于掃描周期的縮短。Z80輸入/輸出指令格式較短，相應的輸入/輸出設備編碼也較短，所以相應的譯碼硬件器較簡單。由于Z80的信息是采用輸入/輸出映射方式，因而設計流程序時，對輸入/輸出與存儲器尋址容易區別。

②用單片機作CPU

自從1974年出現單片機以來，已有不少產品采用單片機做可編程序控制器。日本三菱F系列PLC就采用美國IN公司MES－48系列的單片機8049和8039做處理器，8039單片機在一塊片子上集成了8位的CPU，128×8的數據存儲器。27條輸入/輸出線，T0、T1、INT測試線及8位定時器/計數器，時鐘振蕩電路等。

自80年代以來，出現了集成度更高。功能更強，并帶有“布爾機"而又便于作數據通信的MCS-51系列單片機以及功能更高的16位單片機，大有取代MCS－48系列之勢。日本三菱的F2系列PLC即采用CPU8031。MCS－51系列單片機是美國IN公司在MCS－48單片機基礎上，于80年代初推出的產品，具有高集成度、高可靠性、高功能、高速度、低價格等特點。它有三個代表產品：8051、8751和8031，它們分別有不同的應用特性。8051是以4K字節EPR0M代替4K字節的R0M的8051； 8031是內部無R0M8051。必須外接EPR0M；IN公司的96系列的單片機，字長為16，運算速度比51系列更高，這必將為高檔次的PLC開發和應用帶來美好的遠景。用單片機制成的PLC有以下顯著特點：為機電設備一體化創造了條件，因為由單片機制成PLC，體積更小。同時PLC邏輯功能很強，并且具有數值運算和通信接口。
