  西門子的(de)普(pu)通電機模(mo)塊的(de)應用(yong)及分析

    首先功能：程(cheng)(cheng)序在遠程(cheng)(cheng)模式(shi)下使能，遠程(cheng)(cheng)分(fen)手(shou)動(dong)(dong)和自動(dong)(dong)方(fang)式(shi)。具有空開、故障、啟動(dong)(dong)失敗報警（適用(yong)于有或*信號的情況）；電(dian)機(ji)狀態(tai)字可(ke)用(yong)于上位自作電(dian)機(ji)的多狀態(tai)顯示，每臺電(dian)機(ji)的數據采用(yong)UDT打包方(fang)式(shi)，便(bian)于編程(cheng)(cheng)。

#auto和#man信(xin)號如果(guo)來自一個(ge)三位自鎖旋(xuan)鈕(niu)的話(hua)，輸出是會(hui)斷；

自動(dong)啟停也好，手(shou)動(dong)啟停也好，其本質是不同的(de)(de)來源的(de)(de)啟停指(zhi)令，其程(cheng)序作用(yong)是一樣(yang)的(de)(de)，但樓主卻(que)(que)使用(yong)了兩種邏(luo)輯來做同一件(jian)事(shi)情，這是簡單(dan)邏(luo)輯還好做，但是復雜邏(luo)輯控制要實現就顯得(de)雜亂了。既然有START FAILED，那也會有STOP FAILED。出錯判斷時(shi)間(jian)，調節(jie)不靈活，不如直(zhi)接(jie)用(yong)定(ding)時(shi)器(qi)，但卻(que)(que)是個FC。電機的(de)(de)狀態邏(luo)輯也是不甚合(he)理。
