 在工業(yè)生產過程中，大量的開關量順序控制，它按照邏輯條件進行順序動作，并按照邏輯關系進行連鎖保護動作的控制，及大量離散量的數據采集。傳統上，這些功能是通過氣動或電氣控制系統來實現的。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，美國數字公司研制出了基于集成電路和電子技術的控制裝置，*采用程序化的手段應用于電氣控制，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字運算操作的電子系統，專為在工業(yè)環(huán)境下應用而設計。它采用可編程序的存貯器，用來在其內部存貯執(zhí)行邏輯運算、順序控制、定時、計數和算術運算等操作的指令，并通過數字的、模擬的輸入和輸出，控制各種類型的機械或生產過程。可編程序控制器及其有關設備，都應按易于與工業(yè)控制系統形成一個整體，易于擴充其功能的原則設計。
    上世紀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、數字運算能力、人機接口能力和網絡能力得到大幅度提高，PLC逐漸進入過程控制領域，在某些應用上取代了在過程控制領域處于統治地位的DCS系統。
　　PLC具有通用性強、使用方便、適應面廣、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，在可預見的將來，是無法取代的。

 從結構上分，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。
