目前，世界上有200多個廠家生產可編程序控制器產品，廠家有德國的西門子，美國的Rockwell(AB)、通用(GE),日本的三菱、歐姆龍，法國的施耐德等。

可編程序控制器總的發(fā)展趨勢是向高集成度、小體積、大容量、高速度、易使用、高性能方向發(fā)展。具體表現在以下幾個方面：

(1)向小型化、專用化、低成本方向發(fā)展

20世紀80年代初，小型PLC在價格上還高于小系統(tǒng)用的繼電器控制裝置。隨著微電子技術的發(fā)展，新型器件大幅度的提高功能和降低價格，使PLC結構更為緊湊，功能不斷增加，將原來大、中型PLC才有的功能移植到小型PLC上，如模擬量處理、數據通訊和復雜的功能指令等，但價格不斷下降，真正成為繼電器控制系統(tǒng)的替代產品。

(2)向大容量，高速度方向發(fā)展

大型PLC采用多微處理器系統(tǒng)，有的采用32位微處理器，可同時進行多任務操作，處理速度提高，特別是增強了過程控制和數據處理的功能。另外，存儲容量大大增加。

(3)與計算機聯系密切

從功能上看，PLC不僅能完成邏輯運算，且計算機的復雜運算功能在PLC中也進一步得到利用，從結構上看，計算機的硬件和技術越來越多地應用到PLC；從語言上看，PLC己不再是單純用梯形圖語言，而且可用多種語言編程，如類似計算機匯編語言的語句表，甚至可直接由計算機語言編程；在通訊方面，PLC與計算機可直接相連并進行信息傳遞。

(4)發(fā)展多樣化

可編程序控制器發(fā)展的多樣化體現在3個方面：產品類型、編程語言和應用領域。

(5)模塊化

PLC的擴展模塊發(fā)展迅速。功能明確化、專用化的復雜功能由專門模塊來完成。主機僅僅通過通訊設備向模塊發(fā)布命令和測試狀態(tài)，這使得PLC的系統(tǒng)功能進一步增強，控制系統(tǒng)設計進一步簡化。

(6)網絡與通訊能力增強

計算機與PLC之間以及各個PLC之間的聯網和通訊的能力不斷增強，使用工業(yè)網絡可以有效地節(jié)省資源、降低成本、提高系統(tǒng)可靠性和靈活性，致使網絡的應用有普遍化的趨勢。

(7)多樣化與標準化

生產PLC產品的各廠家都在大力度地開發(fā)自己的新產品，以求占據市場的更大份額。因此產品向多樣化方向發(fā)展，出現了歐、美、日多種流派。與此同時，為了推動技術標準化的進程。一些國際性組織，如國際電工委員會(IEC)不斷為PLC的發(fā)展制定一些新的標準，如對各種類型的產品作一定的歸納或定義，或對PLC未來的發(fā)展制定一種方向或框架。

(8)工業(yè)軟件發(fā)展迅速

與可編程序控制器硬件技術的發(fā)展相適應，工業(yè)軟件的發(fā)展非常迅速，它使系統(tǒng)應用更加簡單易行，大大方便了PLC系統(tǒng)的開發(fā)人員和操作使用人員。

可編程序控制器的輸出信號類型可以是開關量、模擬量和數字量。輸出單元從廣義上分包含兩部分：一是與被控設備相連接的接口電路，另一部分是輸出的映像寄存器。

PLC運行時CPU從輸入映像寄存器讀取輸入信息并進行處理，將處理結果放到輸出映像寄存器。輸出映像寄存器由輸出點相對應的觸發(fā)器組成，輸出接口電路將其由弱電控制信號轉換成現場需要的強電信號輸出，以驅動電磁閥、接觸器、指示燈等被控設備的執(zhí)行元件。
