PLC的*處理器(CPU 一般由控制器、運算器和寄存器組成,這些電路都集成在一個芯片內(nèi)。CPU通過數(shù)據(jù)總線、地址總線和控制總線與存儲單元、輸入/輸出接口電路相連接。

與一般的計算機一樣,CPU是整個PLC的控制中樞,它按PLC中系統(tǒng)程序賦予的功能指揮PLC有條不紊的進行工作。CPU主要完成下述工作:
(1)接收、存儲用戶通過編程器等輸入設(shè)備輸入的程序和數(shù)據(jù)。
(2)用掃描的方式通過I/O部件接收現(xiàn)場信號的狀態(tài)或數(shù)據(jù),并存入輸入映像寄存器或數(shù)據(jù)存儲器中。
(3)診斷PLC內(nèi)部電路的工作故障和編程中的語法錯誤等。
(4) PLC進入運行狀態(tài)后,執(zhí)行用戶程序,完成各種數(shù)據(jù)的處理、傳輸和存儲相應(yīng)的內(nèi)部控制信號,以完成用戶指令規(guī)定的各種操作。
(5)響應(yīng)各種外圍設(shè)備(如編程器、打印機等)的請求。
PLC采用的CPU隨機型不同而不同, 目前,小型PLC為單CPU系統(tǒng),中型及大型則采用雙CPU甚至多CPU系統(tǒng)。目前,PLC通常采用的微處理器有三種:通用微處理器、單片微處理器(即單片機)、位片式微處理器。
