2、梯發(fā)展到了現(xiàn)在的群控電梯，為高層運(yùn)輸做出了不可磨滅的貢獻(xiàn)。PLC在電梯控制上的應(yīng)用主要體現(xiàn)在它的邏輯開(kāi)關(guān)控制功能。由于PLC具有邏輯運(yùn)算，計(jì)數(shù)和定時(shí)以及數(shù)據(jù)輸入輸出的功能。在電梯控制過(guò)程中，各種邏輯開(kāi)關(guān)控制與PLC很好的結(jié)合，很好的實(shí)現(xiàn)了對(duì)電梯的控制。本文主要討論研究利用西門子公司的可編程控制器對(duì)三層電梯的控制，形成電梯控制系統(tǒng)。關(guān)鍵詞：plc電梯；控制系統(tǒng)；電梯系統(tǒng)運(yùn)行檢修和調(diào)試46TheDesignofThreeElevatorSystemBasedonPLCAbstract：PLC(Programma
