國(guó)際電工委員會(huì)(IEC)在1985年的PLC標(biāo)準(zhǔn)草案第3稿中,對(duì)PLC作了如下定義:“是一種數(shù)字運(yùn)算操作的電子系統(tǒng),專為在工業(yè)環(huán)境下應(yīng)用而設(shè)計(jì)。它采用可編程序的存儲(chǔ)器,用來在其內(nèi)部存儲(chǔ)執(zhí)行邏輯運(yùn)算、順序控制、定時(shí)、計(jì)數(shù)和算術(shù)運(yùn)算等操作的指令,并通過數(shù)字式、模擬式的輸入和輸出,控制各種類型的機(jī)械或生產(chǎn)過程。可編程序控制器及其有關(guān)設(shè)備,都應(yīng)按易于使工業(yè)控制系統(tǒng)形成一個(gè)整體,易于擴(kuò)充其功能的原則設(shè)計(jì)。”從上述定義可以看出,PLC是一種用程序來改變控制功能的工業(yè)控制計(jì)算機(jī),除了能完成各種各樣的控制功能外,還有與其他計(jì)算機(jī)通信聯(lián)網(wǎng)的功能
