由于剛學(xué)習plc技術(shù)，不懂。故求三臺電動(dòng)機的順序控制。要求：SB1按下   M1啟動(dòng)    5s后M2啟動(dòng)    再10s后M3啟動(dòng)
                              SB2按下   M3停止    3s后M2停止    接著(zhù)9shou M1停止   最后再12s后系統重啟。
                               （1）用經(jīng)典的梯形圖畫(huà)出
                               （2）用步進(jìn)控制畫(huà)出梯形圖         （PLC為三菱的FN2X型的）

你還是先看看書(shū)吧   看一些入門(mén)的書(shū)，上面都有的，看不懂的地方再來(lái)家園問(wèn)，
