在工業(yè)生產(chǎn)過程中,大量的開關(guān)量順序控制,它按照邏輯條件進行順序動作,并按照邏輯關(guān)系進行連鎖保護動作的控制,及大量離散量的數(shù)據(jù)采集。傳統(tǒng)上,這些功能是通過氣動或電氣控制系統(tǒng)來實現(xiàn)的。1968年美國GM(通用汽車)公司提出取代繼電氣控制裝置的要求,第二年,美國數(shù)字公司研制出了基于集成電路和電子技術(shù)的控制裝置,*采用程序化的手段應(yīng)用于電氣控制,這就是*代可編程序控制器,稱Programmable Controller(PC)。
個人計算機(簡稱PC)發(fā)展起來后,為了方便,也為了反映可編程控制器的功能特點,可編程序控制器定名為Programmable Logic Controller(PLC),現(xiàn)在,仍常常將PLC簡稱PC。

PLC的定義有許多種。電工委員會(IEC)對PLC的定義是:可編程控制器是一種數(shù)字運算操作的電子系統(tǒng),專為在工業(yè)環(huán)境下應(yīng)用而設(shè)計。它采用可編程序的存貯器,用來在其內(nèi)部存貯執(zhí)行邏輯運算、順序控制、定時、計數(shù)和算術(shù)運算等操作的指令,并通過數(shù)字的、模擬的輸入和輸出,控制各種類型的機械或生產(chǎn)過程。可編程序控制器及其有關(guān)設(shè)備,都應(yīng)按易于與工業(yè)控制系統(tǒng)形成一個整體,易于擴充其功能的原則設(shè)計。
上世紀(jì)80年代至90年代中期,是PLC發(fā)展zui快的時期,年增長率一直保持為30~40%。在這時期,PLC在處理模擬量能力、數(shù)字運算能力、人機接口能力和網(wǎng)絡(luò)能力得到大幅度提高,PLC逐漸進入過程控制領(lǐng)域,在某些應(yīng)用上取代了在過程控制領(lǐng)域處于統(tǒng)治地位的DCS系統(tǒng)。
PLC具有通用性強、使用方便、適應(yīng)面廣、可靠性高、抗*力強、編程簡單等特點。PLC在工業(yè)自動化控制特別是順序控制中的地位,在可預(yù)見的將來,是無法取代的。
從結(jié)構(gòu)上分,PLC分為固定式和組合式(模塊式)兩種。固定式PLC包括CPU板、I/O板、顯示面板、內(nèi)存塊、電源等,這些元素組合成一個不可拆卸的整體。模塊式PLC包括CPU模塊、I/O模塊、內(nèi)存、電源模塊、底板或機架,這些模塊可以按照一定規(guī)則組合配置。
