作為離散控制的產(chǎn)品，PLC（可編程控制器）在我國(guó)的應(yīng)用已有30多年的歷史。PLC自20世紀(jì)70年代后期進(jìn)入以來(lái)，應(yīng)用增長(zhǎng)十分迅速。

國(guó)外PLC（可編程控制器）廠家有歐姆龍、三菱、西門子等。PLC從 初的引進(jìn)外國(guó)，到后來(lái)吸收PLC的關(guān)鍵技術(shù)試圖進(jìn)行國(guó)產(chǎn)化，PLC經(jīng)過(guò)了一個(gè)迅速發(fā)展的歷程。目前國(guó)產(chǎn)PLC廠商眾多，主要集中在臺(tái)灣、深圳以及江浙一帶。例如：臺(tái)達(dá)、永宏、盟立、和利時(shí)等。

每個(gè)廠商的規(guī)模也不一樣。國(guó)內(nèi)廠商的PLC主要集中于小型PLC，例如歐辰、億維等；還有一些廠商生產(chǎn)中型PLC，例如盟立、南大傲拓等。還有許多小廠商是貼牌生產(chǎn)或是仿造生產(chǎn)，真正自主研發(fā)生產(chǎn)的在少數(shù)，而且集中在臺(tái)灣，并且臺(tái)灣廠商比大陸廠商做的更好些，市場(chǎng)也更廣闊。

但是，PLC做了這么久，卻也一直沒(méi)有很大的進(jìn)步，并沒(méi)有突破，也未能打入市場(chǎng)，只能在本地有一個(gè)單一的、小范圍的市場(chǎng)。若想要有一個(gè)很大的跳躍，不僅要向國(guó)外學(xué)習(xí)，還需要自己鉆研，不能經(jīng)常模仿，國(guó)產(chǎn)PLC的弱點(diǎn)就在于技術(shù)不過(guò)關(guān)。而國(guó)產(chǎn)PLC的 在于市場(chǎng)廣闊。做PLC的類型需要增多，不能 于冶金、電力、自動(dòng)化生產(chǎn)等，應(yīng)該擴(kuò)大到各個(gè)制造業(yè)的設(shè)備和系統(tǒng)。
