 PLC的發(fā)展歷程

    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(jìn)行順序動(dòng)作，并按照邏輯關(guān)系進(jìn)行連鎖保護(hù)動(dòng)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(dòng)或電氣控制系統(tǒng)來實(shí)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(gè)人計(jì)算機(jī)（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(diǎn)，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(huì)（IEC）對(duì)PLC的定義是：可編程控制器是一種數(shù)字運(yùn)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(jì)。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(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)過程?？删幊绦蚩刂破骷捌溆嘘P(guān)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)。

    上世紀(jì)80年代至90年代中期，是PLC發(fā)展zui快的時(shí)期，年增長率一直保持為30~40%。在這時(shí)期，PLC在處理模擬量能力、數(shù)字運(yùn)算能力、人機(jī)接口能力和網(wǎng)絡(luò)能力得到大幅度提高，PLC逐漸進(jìn)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(qiáng)、使用方便、適應(yīng)面廣、可靠性高、抗*力強(qiáng)、編程簡單等特點(diǎn)。PLC在工業(yè)自動(dòng)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。
