三層電梯控制系統(tǒng)PLC編程

1、三層電梯控制系統(tǒng)PLC編程    一、 實(shí)驗(yàn)?zāi)康?、 通過(guò)對(duì)工程實(shí)例的模擬，熟練地掌握PLC的編程和程序調(diào)試方法。2、 進(jìn)一步熟悉PLC的I/O連接。3、 熟悉三層樓電梯采用轎廂內(nèi)外按鈕控制的編程方法。二、控制要求電梯由安裝在各樓層廳門口的上升和下降呼叫按鈕進(jìn)行呼叫操縱，其操縱內(nèi)容為電梯運(yùn)行方向。電梯轎廂內(nèi)設(shè)有樓層內(nèi)選按鈕S1S3，用以選擇需?？康臉菍?。 L1為一層指示、L2為二層指示、L3為三層指示，SQ1SQ3為到位行程開(kāi)關(guān)。電梯上升途中只響應(yīng)上升呼叫，下降途中只響應(yīng)下降呼叫，任何反方向的呼叫均無(wú)效。例如，電梯停在一層，在三層轎廂外呼叫時(shí)，必須按三層

2、上升呼叫按鈕，電梯才響應(yīng)呼叫(從一層運(yùn)行到三層)，按三層下降呼叫按鈕無(wú)效;反之，若電梯停在三層，在一層轎廂外呼叫時(shí)，必須按一層下降呼叫按鈕，電梯才響應(yīng)呼叫，按三層上升呼叫按鈕無(wú)效，依此類推。三、 編制梯形圖并寫出程序，參考程序 表6-10-1所示步序指 令步序指 令0LD T4813OLD1O T5614LD T672O T7515AN T683AN I0.216OLD4AN M0.117OLD5AN M0.518AN Q0.06LD T3819AN Q0.17AN T3920= Q0.28LD T5021LD T529AN T5122O T6410OLD23AN I0.111LD T6724
