可編程邏輯控制器(Programmable Logic Controller，PLC)，一種具有
微處理器的用于
自動化控制的數(shù)字運(yùn)算控制器，可以將控制指令隨時載入內(nèi)存進(jìn)行儲存與執(zhí)行？删幊炭刂破饔蒀PU、指令及數(shù)據(jù)內(nèi)存、輸入/輸出接口、電源、數(shù)字模擬轉(zhuǎn)換等功能單元組成。早期的可編程邏輯控制器只有邏輯控制的功能，所以被命名為可編程邏輯控制器，后來隨著不斷地發(fā)展，這些當(dāng)初功能簡單的計算機(jī)模塊已經(jīng)有了包括邏輯控制、時序控制、模擬控制、多機(jī)通信等各類功能，名稱也改為可編程控制器(Programmable Controller)，但是由于它的簡寫PC與個人電腦(Personal Computer)的簡寫相沖突，加上習(xí)慣的原因，人們還是經(jīng)常使用可編程邏輯控制器這一稱呼，并仍使用PLC這一縮寫。
[2]
現(xiàn)在工業(yè)上使用的可編程邏輯控制器已經(jīng)相當(dāng)或接近于一臺緊湊型電腦的主機(jī)，其在擴(kuò)展性和可靠性方面的優(yōu)勢使其被廣泛應(yīng)用于目前的各類工業(yè)控制領(lǐng)域。不管是在計算機(jī)直接控制系統(tǒng)還是集中分散式控制系統(tǒng)DCS，或者現(xiàn)場總線控制系統(tǒng)FCS中，總是有各類PLC控制器的大量使用。PLC的生產(chǎn)廠商很多，如
西門子、
施耐德、
三菱、臺達(dá)等，幾乎涉及工業(yè)自動化領(lǐng)域的廠商都會有其PLC產(chǎn)品提供
