FX2N-32ES 原裝編程器分為兩種，一種是手持編程器，方便。我們實驗室使用的就是手持編程器。二種是通過PLC的RS232口。與計算機相連。然后敲擊鍵盤。通過NSTP-GR軟件（或WINDOWS下軟件）向PLC內部輸入程序。
第二節(jié) PLC的基本工作原理
一．PLC采用“順序掃描，不斷循環(huán)”的工作方式
1．每次掃描過程。集中對輸入信號進行采樣。集中對輸出信號進行刷新。
2．輸入刷新過程。當輸入端口關閉時，程序在進行執(zhí)行階段時，輸入端有新狀態(tài)，新狀態(tài)不能被讀入。只有程序進行下一次掃描時，新狀態(tài)才被讀入。
3．一個掃描周期分為輸入采樣，程序執(zhí)行，輸出刷新。
4．元件映象寄存器的內容是隨著程序的執(zhí)行變化而變化的。
5．掃描周期的長短由三條決定。（1）CPU執(zhí)行指令的速度（2）指令本身占有的時間（3）指令條數
6．由于采用集中采樣。集中輸出的方式。存在輸入/輸出滯后的現(xiàn)象，即輸入/輸出響應延遲。
FX2N-32ES 原裝二．PLC與繼電器控制系統(tǒng)、微機區(qū)別
1．PLC與繼電器控制系統(tǒng)區(qū)別
前者工作方式是“串行”，后者工作方式是“并行”。
前者用“軟件”，后者用“硬件”。型 號 說 明
