在工業(yè)生產(chǎn)過(guò)程中,大量的開(kāi)關(guān)量順序控制,它按照邏輯條件進(jìn)行順序動(dòng)作,并按照邏輯關(guān)系進(jìn)行連鎖保護(hù)動(dòng)作的控制,及大量離散量的數(shù)據(jù)采集。傳統(tǒng)上,這些功能是通過(guò)氣動(dòng)或電氣控制系統(tǒng)來(lái)實(shí)現(xiàn)的。1968年美國(guó)GM(通用汽車(chē))公司提出取代繼電氣控制裝置的要求,第二年,美國(guó)數(shù)字公司研制出了基于集成電路和電子技術(shù)的控制裝置,首次采用程序化的手段應(yīng)用于電氣控制,這就是代可編程序控制器,稱(chēng)Programmable Controller(PC)。
????個(gè)人計(jì)算機(jī)(簡(jiǎn)稱(chēng)PC)發(fā)展起來(lái)后,為了方便,也為了反映可編程控制器的功能特點(diǎn),可編程序控制器定名為Programmable Logic Controller(PLC),現(xiàn)在,仍常常將PLC簡(jiǎn)稱(chēng)PC。
