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(gè)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(chǎng)輸入裝置送來(lái)的狀態(tài)或數(shù)據(jù),并存入規(guī)定的寄存器中,同時(shí),診斷電源和PLC內(nèi)部電路的工作狀態(tài)和編程過(guò)程中的語(yǔ)法錯(cuò)誤等。進(jìn)入運(yùn)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(hào),去指揮有關(guān)的控制電路。
