可編程序控制器一直在發(fā)展中,所以至今尚未對其下最后的定義。國際電工學會(iec)曾先后于1982.11;1985.1和1987.2發(fā)布了可編程序控制器標準草案的第一,二,三稿。
在第三稿中,對plc作了如下定義:可編程序控制器是一種數(shù)字運算操作電子系統(tǒng),專為在工業(yè)環(huán)境下應(yīng)用而設(shè)計。它采用了可編程序的存儲器,用來在其內(nèi)部存儲執(zhí)行邏輯運算、順序控制、定時、計數(shù)和算術(shù)運算等操作的指令,并通過數(shù)字的,模擬的輸入和輸出,控制各種類型的機械或生產(chǎn)過程?删幊绦蚩刂破骷捌溆嘘P(guān)的外圍設(shè)備,都應(yīng)按易于與工業(yè)控制系統(tǒng)形成一個整體、易于擴充其功能的原則設(shè)計。
