PLC采用“順序掃描，不斷循環(huán)"的工作方式：⑴每次掃描過程，集中采集輸入信號(hào)，集中對(duì)輸出信號(hào)進(jìn)行刷新;⑵輸入刷新過程，當(dāng)輸入端口關(guān)閉時(shí)，程序在進(jìn)行執(zhí)行階段時(shí)，輸入端有新狀態(tài)，新狀態(tài)不能被讀入。只有程序進(jìn)行下一次掃描時(shí)，新狀態(tài)才被讀入;⑶一個(gè)掃描周期分為輸入采樣，程序執(zhí)行，輸出刷新;⑷元件映象寄存器的內(nèi)容是隨著程序的執(zhí)行變化而變化的。本特利轉(zhuǎn)速模塊3500/50-01-00-01
