CPU的構(gòu)成
CPU是PLC的核心,起神經(jīng)中樞的作用,每套PLC至少有一個CPU,它按PLC的系統(tǒng)程序賦予的功能接收并存貯用戶程序和數(shù)據(jù),用掃描的方式采集由現(xiàn)場輸入裝置送來的狀態(tài)或數(shù)據(jù),并存入規(guī)定的寄存器中,同時,診斷電源和PLC內(nèi)部電路的工作狀態(tài)和編程過程中的語法錯誤等。進入運行后,從用戶程序存貯器中逐條讀取指令,經(jīng)分析后再按指令規(guī)定的任務(wù)產(chǎn)生相應(yīng)的控制信號,去指揮有關(guān)的控制電路。
CPU主要由運算器、控制器、寄存器及實現(xiàn)它們之間的數(shù)據(jù)、控制及狀態(tài)總線構(gòu)成,CPU單元還包括外圍芯片、總線接口及有關(guān)電路。內(nèi)存主要用于存儲程序及數(shù)據(jù),是PLC*的組成單元。
