現在工業上使用的可編程邏輯控制器已經相當或接近于一臺緊湊型電腦的主機，其在擴展性和可靠性方面的優勢使其被廣泛應用于目前的各類工業控制領域。不管是在計算機直接控制系統還是集中分散式控制系統DCS，或者現場總線控制系統FCS中，總是有各類PLC控制器的大量使用。PLC的生產廠商很多，如西門子、施耐德、三菱、臺達等，幾乎涉及工業自動化領域的廠商都會有其PLC產品提供。
美國汽車工業生產技術要求的發展促進了PLC的產生，20世紀60年代，美國通用汽車公司在對工廠生產線調整時，發現繼電器、接觸器控制系統修改難、體積大、噪聲大、維護不方便以及可靠性差，于是提出了的“通用十條”招標指標。 [3] 
1969年，美國數字化設備公司研制出 一臺可編程控制器(PDP-14)，在通用汽車公司的生產線上試用后，*；1971年，日本研制出 一臺可編程控制器(DCS-8)；1973年，德國研制出 一臺可編程控制器；1974年，我國開始研制可編程控制器：1977年，我國在工業應用領域推廣PLC。 [3] 
初的目的是替代機械開關裝置(繼電模塊)。然而，自從1968年以來，PLC的功能逐漸代替了繼電器控制板，現代PLC具有更多的功能。其用途從單一過程控制延伸到整個制造系統的控制和監測。 [4]
