外部的開關(guān)信號(hào)、模擬信號(hào)以及各種傳感器檢測(cè)信號(hào)作為PLC的輸入變量,它們經(jīng)PLC的輸入端子進(jìn)入PLC的輸入存儲(chǔ)器,收集和暫存被控對(duì)象實(shí)際運(yùn)行的狀態(tài)信息和數(shù)據(jù);經(jīng)PLC內(nèi)部運(yùn)算與處理后,按被控對(duì)象實(shí)際動(dòng)作要求產(chǎn)生輸出結(jié)果;輸出結(jié)果送到輸出端子作為輸出變量,驅(qū)動(dòng)執(zhí)行機(jī)構(gòu)。由 PLC 的工作過程可見,在 PLC 的程序執(zhí)行階段,即使輸入發(fā)生了變化,輸入狀態(tài)寄存器的內(nèi)容也不會(huì)立即改變,要等到下一個(gè)周期輸入處理階段才能改變。暫存在輸出狀態(tài)寄存器中的輸出信號(hào),等到一個(gè)循環(huán)周期結(jié)束, CPU 集中將這些輸出信號(hào)全部輸出給輸出鎖存器,這才成為實(shí)際的 CPU 輸出。因此全部輸入、輸出狀態(tài)的改變就需要一個(gè)掃描周期,換言之,輸入、輸出的狀態(tài)保持一個(gè)掃描周期。
