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(jìn)行采樣。集中對輸出信號進(jìn)行刷新。
2．輸入刷新過程。當(dāng)輸入端口關(guān)閉時，程序在進(jìn)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(jìn)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(nèi)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(shù)
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(yīng)延遲。
二．PLC與繼電器控制系統(tǒng)、微機(jī)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”。
2．PLC與微機(jī)區(qū)別
前者工作方式是“循環(huán)掃描”。后者工作方式是“待命或中斷”
PLC 編程方式
PLC最突出的優(yōu)點采用“軟繼電器”代替“硬繼電器”。用“軟件編程邏輯”代替“硬件布線邏輯”。
PLC編程語言有梯形圖、布爾助記符語言，等等。尤其前兩者為常用。
梯形圖語言特點：
1．每個梯形圖由多個梯級組成。
2．梯形圖中左右兩邊的豎線表示假想的邏輯電源。當(dāng)某一梯級的邏輯運算結(jié)果為“1”時，有假想的電流通過。
3．繼電器線圈只能出現(xiàn)一次，而它的常開、常閉觸點可以出現(xiàn)無數(shù)次。
4．每一梯級的運算結(jié)果，立即被后面的梯級所利用。
5．輸入繼電器受外部信號控制。只出現(xiàn)觸點，不出現(xiàn)線圈。
第四節(jié) 主要技術(shù)性能
用戶程序存儲容量：是衡量可存儲用戶應(yīng)用程序多少的指標(biāo)。通常以字或K字為單位。16位二進(jìn)制數(shù)為一個字，每1024個字為1K字。PLC以字為單位存儲指令和數(shù)據(jù)。一般的邏輯操作指令每條占1個字。定時/計數(shù)，移位指令占2個字。數(shù)據(jù)操作指令占2~4個字。
每五節(jié) PLC的分類
按結(jié)構(gòu)分類：
1． 整體式：是把PLC各組成部分安裝在一起或少數(shù)幾塊印刷電路板上，并連同電源一起裝在機(jī)殼內(nèi)形成一個單一的整體，稱之為主機(jī)或基本單元、小型、超小型PLC采用這種結(jié)構(gòu)。
模塊式：是把PLC各基本組成做成獨立的模塊。中型、大型PLC采用這種方式。便于維修。
