在PLC誕生之前，繼電器控制系統(tǒng)已廣泛應(yīng)用于工業(yè)生產(chǎn)的各個(gè)領(lǐng)域，起著不可替代的作用。隨著生產(chǎn)規(guī)模的逐步擴(kuò)大，繼電器控制系統(tǒng)已越來(lái)越難以適應(yīng)現(xiàn)代工業(yè)生產(chǎn)的要求。繼電器控制系統(tǒng)通常是針對(duì)某一固定的動(dòng)作順序或生產(chǎn)工藝而設(shè)計(jì)，他的控制功能也局限于邏輯控制、定時(shí)、計(jì)數(shù)等一些簡(jiǎn)單的控制，一旦動(dòng)作順序或生產(chǎn)工藝發(fā)生變化，就必須重新進(jìn)行設(shè)計(jì)、布線、裝配和調(diào)試，造成時(shí)間和資金的嚴(yán)重浪費(fèi)。繼電器控制系統(tǒng)體積大、耗電多、可靠性差、壽命短、運(yùn)行速度慢、適應(yīng)性差。為了改變這一現(xiàn)狀，1968年美國(guó)zui大的汽車制造商通用汽車公司（GM），為了適應(yīng)汽車型號(hào)不斷更新的需求，并能在競(jìng)爭(zhēng)激烈的汽車工業(yè)中占有優(yōu)勢(shì)，提出要研制一種新型的工業(yè)控制裝置來(lái)取代繼電器控制裝置，為此，擬定了10項(xiàng)公開(kāi)招標(biāo)的技術(shù)要求，即：
1、 編程簡(jiǎn)單，可在現(xiàn)場(chǎng)修改程序
2、 維護(hù)方便，是插件式
3 、可靠性高于繼電器控制柜
4 、體積小于繼電器控制柜
5 、可將數(shù)據(jù)直接送入管理計(jì)算機(jī)
6 、在成本上可與繼電器控制柜競(jìng)爭(zhēng)
7、輸入可以是交流115V
8、輸出可以是交流115V，2A以上，可直接驅(qū)動(dòng)電磁閥等
9、 在擴(kuò)展時(shí)，原有系統(tǒng)只要很小變更
10 、用戶程序存儲(chǔ)器容量至少能擴(kuò)展到4K

目前，隨著大規(guī)模和超大規(guī)模集成電路等微電子技術(shù)的發(fā)展，PLC已由zui初一位機(jī)發(fā)展到現(xiàn)在的以16位和32位微處理器構(gòu)成的微機(jī)化PC，而且實(shí)現(xiàn)了多處理器的多通道處理。如今，PLC技術(shù)已非常成熟，不僅控制功能增強(qiáng)，功耗和體積減小，成本下降，可靠性提高，編程和故障檢測(cè)更為靈活方便，而且隨著遠(yuǎn)程I/O和通信網(wǎng)絡(luò)、數(shù)據(jù)處理以及圖象顯示的發(fā)展，使PLC向用于連續(xù)生產(chǎn)過(guò)程控制的方向發(fā)展，成為實(shí)現(xiàn)工業(yè)生產(chǎn)自動(dòng)化的一大支柱。
現(xiàn)在，世界上有200多家PLC生產(chǎn)廠家，400多品種的PLC產(chǎn)品，按地域可分成美國(guó)、歐洲、和日本等三個(gè)流派產(chǎn)品，各流派PLC產(chǎn)品都各具特色。其中，美國(guó)是PLC生產(chǎn)大國(guó)，有100多家PLC廠商，*的有A-B公司、通用電氣（GE）公司、*康（MODICON）公司。歐洲PLC產(chǎn)品主要制造商有德國(guó)的西門子（SIEMENS）公司、AEG公司、法國(guó)的TE公司。日本有許多PLC制造商，如三菱、歐姆龍、松下、富士等，韓國(guó)的三星（SAMSUNG）、LG等，這些生產(chǎn)廠家的產(chǎn)品占有80%以上的PLC*。
