在PLC誕生之前，繼電器控制系統已廣泛應用于工業生產的各個領域，起著不可替代的作用。隨著生產規模的逐步擴大，繼電器控制系統已越來越難以適應現代工業生產的要求。繼電器控制系統通常是針對某一固定的動作順序或生產工藝而設計，他的控制功能也局限于邏輯控制、定時、計數等一些簡單的控制，一旦動作順序或生產工藝發生變化，就必須重新進行設計、布線、裝配和調試，造成時間和資金的嚴重浪費。繼電器控制系統體積大、耗電多、可靠性差、壽命短、運行速度慢、適應性差。為了改變這一現狀，1968年美國zui大的汽車制造商通用汽車公司（GM），為了適應汽車型號不斷更新的需求，并能在競爭激烈的汽車工業中占有優勢，提出要研制一種新型的工業控制裝置來取代繼電器控制裝置，為此，擬定了10項公開招標的技術要求，即：
1、 編程簡單，可在現場修改程序
2、 維護方便，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 、可將數據直接送入管理計算機
6 、在成本上可與繼電器控制柜競爭
7、輸入可以是交流115V
8、輸出可以是交流115V，2A以上，可直接驅動電磁閥等
9、 在擴展時，原有系統只要很小變更
10 、用戶程序存儲器容量至少能擴展到4K

目前，隨著大規模和超大規模集成電路等微電子技術的發展，PLC已由zui初一位機發展到現在的以16位和32位微處理器構成的微機化PC，而且實現了多處理器的多通道處理。如今，PLC技術已非常成熟，不僅控制功能增強，功耗和體積減小，成本下降，可靠性提高，編程和故障檢測更為靈活方便，而且隨著遠程I/O和通信網絡、數據處理以及圖象顯示的發展，使PLC向用于連續生產過程控制的方向發展，成為實現工業生產自動化的一大支柱。
現在，世界上有200多家PLC生產廠家，400多品種的PLC產品，按地域可分成美國、歐洲、和日本等三個流派產品，各流派PLC產品都各具特色。其中，美國是PLC生產大國，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產品主要制造商有德國的西門子（SIEMENS）公司、AEG公司、法國的TE公司。日本有許多PLC制造商，如三菱、歐姆龍、松下、富士等，韓國的三星（SAMSUNG）、LG等，這些生產廠家的產品占有80%以上的PLC*。
