目前，世界上有200多個(gè)廠家生產(chǎn)可編程序控制器產(chǎn)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(shì)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(xiàn)在以下幾個(gè)方面：

(1)向小型化、專用化、低成本方向發(fā)展

20世紀(jì)80年代初，小型PLC在價(jià)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(shù)的發(fā)展，新型器件大幅度的提高功能和降低價(jià)格，使PLC結(jié)構(gòu)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(shù)據(jù)通訊和復(fù)雜的功能指令等，但價(jià)格不斷下降，真正成為繼電器控制系統(tǒng)的替代產(chǎn)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(shí)進(jìn)行多任務(wù)操作，處理速度提高，特別是增強(qiáng)了過程控制和數(shù)據(jù)處理的功能。另外，存儲(chǔ)容量大大增加。

(3)與計(jì)算機(jī)聯(lián)系密切

從功能上看，PLC不僅能完成邏輯運(yùn)算，且計(jì)算機(jī)的復(fù)雜運(yùn)算功能在PLC中也進(jìn)一步得到利用，從結(jié)構(gòu)上看，計(jì)算機(jī)的硬件和技術(shù)越來越多地應(yīng)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(jì)算機(jī)匯編語言的語句表，甚至可直接由計(jì)算機(jī)語言編程；在通訊方面，PLC與計(jì)算機(jī)可直接相連并進(jìn)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(xiàn)在3個(gè)方面：產(chǎn)品類型、編程語言和應(yīng)用領(lǐng)域。

(5)模塊化

PLC的擴(kuò)展模塊發(fā)展迅速。功能明確化、專用化的復(fù)雜功能由專門模塊來完成。主機(jī)僅僅通過通訊設(shè)備向模塊發(fā)布命令和測(cè)試狀態(tài)，這使得PLC的系統(tǒng)功能進(jìn)一步增強(qiáng)，控制系統(tǒng)設(shè)計(jì)進(jìn)一步簡化。

(6)網(wǎng)絡(luò)與通訊能力增強(qiáng)

計(jì)算機(jī)與PLC之間以及各個(gè)PLC之間的聯(lián)網(wǎng)和通訊的能力不斷增強(qiáng)，使用工業(yè)網(wǎng)絡(luò)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(wǎng)絡(luò)的應(yīng)用有普遍化的趨勢(shì)。

(7)多樣化與標(biāo)準(zhǔn)化

生產(chǎn)PLC產(chǎn)品的各廠家都在大力度地開發(fā)自己的新產(chǎn)品，以求占據(jù)市場的更大份額。因此產(chǎn)品向多樣化方向發(fā)展，出現(xiàn)了歐、美、日多種流派。與此同時(shí)，為了推動(dòng)技術(shù)標(biāo)準(zhǔn)化的進(jìn)程。一些國際性組織，如國際電工委員會(huì)(IEC)不斷為PLC的發(fā)展制定一些新的標(biāo)準(zhǔn)，如對(duì)各種類型的產(chǎn)品作一定的歸納或定義，或?qū)LC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(shù)的發(fā)展相適應(yīng)，工業(yè)軟件的發(fā)展非常迅速，它使系統(tǒng)應(yīng)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(hào)類型可以是開關(guān)量、模擬量和數(shù)字量。輸出單元從廣義上分包含兩部分：一是與被控設(shè)備相連接的接口電路，另一部分是輸出的映像寄存器。

PLC運(yùn)行時(shí)CPU從輸入映像寄存器讀取輸入信息并進(jìn)行處理，將處理結(jié)果放到輸出映像寄存器。輸出映像寄存器由輸出點(diǎn)相對(duì)應(yīng)的觸發(fā)器組成，輸出接口電路將其由弱電控制信號(hào)轉(zhuǎn)換成現(xiàn)場需要的強(qiáng)電信號(hào)輸出，以驅(qū)動(dòng)電磁閥、接觸器、指示燈等被控設(shè)備的執(zhí)行元件。
