PLC的發(fā)展歷程 

 

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）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，這就是第一代可編程序控制器，稱Programmable Controller（PC）。
