PLC（可編程邏輯控制器，Programmable Logic Controller）是一種專為工業(yè)環(huán)境設(shè)計(jì)的數(shù)字運(yùn)算電子系統(tǒng)，廣泛應(yīng)用于自動(dòng)化控制領(lǐng)域。它通過可編程存儲(chǔ)器執(zhí)行邏輯運(yùn)算、順序控制、定時(shí)、計(jì)數(shù)和算術(shù)運(yùn)算等指令，控制各類機(jī)械設(shè)備或生產(chǎn)過程，被譽(yù)為工業(yè)自動(dòng)化的“大腦”。

PLC主要由中央處理器（CPU）、輸入/輸出（I/O）模塊、電源模塊、存儲(chǔ)器和通信接口構(gòu)成。其工作方式基于循環(huán)掃描機(jī)制，分為三個(gè)階段：

?輸入采樣?：讀取所有輸入信號(hào)狀態(tài)；

?程序執(zhí)行?：按照用戶編寫的邏輯程序進(jìn)行運(yùn)算；

?輸出刷新?：將運(yùn)算結(jié)果發(fā)送至輸出設(shè)備，如電機(jī)、指示燈等。

這種高可靠性、抗干擾能力強(qiáng)的結(jié)構(gòu)設(shè)計(jì)，使其能在高溫、強(qiáng)電磁干擾的工業(yè)現(xiàn)場穩(wěn)定運(yùn)行。
