可編程序控制器，英文稱Programmable Controller，簡(jiǎn)稱PC。但由于PC容易和個(gè)人計(jì)算機(jī)（Personal Computer）混淆，故人們?nèi)粤?xí)慣地用PLC作為可編程序控制器的縮寫。它是一個(gè)以微處理器為核心的數(shù)字運(yùn)算操作的電子系統(tǒng)裝置，專為在工業(yè)現(xiàn)場(chǎng)應(yīng)用而設(shè)計(jì)，它采用可編程序的存儲(chǔ)器，用以在其內(nèi)部存儲(chǔ)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)算等操作指令，并通過(guò)數(shù)字式或模擬式的輸入、輸出接口，控制各種類型的機(jī)械或生產(chǎn)過(guò)程。PLC是微機(jī)技術(shù)與傳統(tǒng)的繼電接觸控制技術(shù)相結(jié)合的產(chǎn)物，它克服了繼電接觸控制系統(tǒng)中的機(jī)械觸點(diǎn)的接線復(fù)雜、可靠性低、功耗高、通用性和靈活性差的缺點(diǎn)，充分利用了微處理器的優(yōu)點(diǎn)，又照顧到現(xiàn)場(chǎng)電氣操作維修人員的技能與習(xí)慣，特別是PLC的程序編制，不需要專門的計(jì)算機(jī)編程語(yǔ)言知識(shí)，而是采用了一套以繼電器梯形圖為基礎(chǔ)的簡(jiǎn)單指令形式，使用戶程序編制形象、直觀、方便易學(xué)；調(diào)試與查錯(cuò)也都很方便。用戶在購(gòu)到所需的PLC后，只需按說(shuō)明書的提示，做少量的接線和簡(jiǎn)易的用戶程序編制工作，就可靈活方便地將PLC應(yīng)用于生產(chǎn)實(shí)踐。
可編程序控制器一直在發(fā)展中，所以至今尚未對(duì)其下zui后的定義。電工學(xué)會(huì)（IEC）曾先后于1982.11；1985.1和1987.2發(fā)布了可編程序控制器標(biāo)準(zhǔn)草案的*，二，三稿。
在第三稿中，對(duì)PLC作了如下定義：可編程序控制器是一種數(shù)字運(yùn)算操作電子系統(tǒng)，專為在工業(yè)環(huán)境下應(yīng)用而設(shè)計(jì)。它采用了可編程序的存儲(chǔ)器，用來(lái)在其內(nèi)部存儲(chǔ)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)算等操作的指令，并通過(guò)數(shù)字的，模擬的輸入和輸出，控制各種類型的機(jī)械或生產(chǎn)過(guò)程。可編程序控制器及其有關(guān)的外圍設(shè)備，都應(yīng)按易于與工業(yè)控制系統(tǒng)形成一個(gè)整體、易于擴(kuò)充其功能的原則設(shè)計(jì)。
