描述

CPU在系統(tǒng)程序的支持下，主要完成下列任務：

(1)在編程方式下，接受從編程器傳送來的用戶程序和數(shù)據(jù)，并將它們存入預定的用戶存儲器與數(shù)據(jù)存儲器。

(2)用掃描方式接受輸入端子的狀態(tài)或數(shù)據(jù)，并存放到輸入映像寄存器或數(shù)據(jù)寄存器中。

(3)診斷電源及PLC內(nèi)部電路工作狀態(tài)和編程中的語法錯誤。

(4)在運行方式下，從存儲器逐條讀取用戶程序，經(jīng)運算后，按指令規(guī)定的任務產(chǎn)生相應的控制信號，去驅(qū)動相關(guān)電路。

(5)由算術(shù)邏輯運算的結(jié)果，更新有關(guān)標志位與元件映像寄存器、數(shù)據(jù)寄存器的內(nèi)容，實現(xiàn)輸出控制、通信、顯示、打印等功能。
