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(xiě)。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(lèi)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(mén)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(shū)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

工業(yè)生產(chǎn)一般對(duì)控制設(shè)備的可靠性要求很高，并且要有很強(qiáng)的抗干擾能力。PLC能在惡劣的環(huán)境中可靠的工作，平均無(wú)故障時(shí)間達(dá)到數(shù)萬(wàn)小時(shí)以上，已被公認(rèn)為*可靠的工業(yè)控制設(shè)備之一。
PLC本身具有較強(qiáng)的自診斷功能，保證硬件核心設(shè)備(CPU、存儲(chǔ)器、I/O總線等)在正常情況下執(zhí)行用戶程序，一旦出現(xiàn)故障則立即給出出錯(cuò)信號(hào)，停止用戶程序的執(zhí)行，切斷所有輸出信號(hào)，等待修復(fù)。PLC的主要模塊均采用大規(guī)模和超大規(guī)模集成電路，I/O系統(tǒng)設(shè)計(jì)有完善的通道保護(hù)與信號(hào)調(diào)理電路。在結(jié)構(gòu)上對(duì)耐熱、防潮、防塵、抗震等都有的考慮，在硬件上采用隔離，屏蔽、濾波、接地等抗干擾措施，在軟件上采用數(shù)字濾波等措施。與繼電器系統(tǒng)和通用計(jì)算機(jī)相比，PLC更能適應(yīng)工業(yè)現(xiàn)場(chǎng)環(huán)境要求。

而且PLC里邊設(shè)計(jì)出了計(jì)數(shù)器和計(jì)時(shí)器，這樣避免使用麻煩的實(shí)物計(jì)時(shí)器和時(shí)間繼電器，修改計(jì)數(shù)和計(jì)時(shí)值非常快捷方便，把以往傳統(tǒng)繼電器很難實(shí)現(xiàn)的時(shí)序邏輯控制做得非常。甚至有些老板擔(dān)心客戶不給錢(qián)，使用萬(wàn)年歷設(shè)定一個(gè)時(shí)鐘，運(yùn)行到某年某月某日某時(shí)某分某秒，自動(dòng)會(huì)停下部分功能來(lái)。
