        PLC自動(dòng)運行狀態(tài)使用多段順序流程控制，運行過(guò)程中出現機械故障或傳感器失效。一般該怎么去處理流程及相關(guān)故障？在人工進(jìn)入手動(dòng)處理完成后如何連接繼續流程。大家一般怎么去處理，是不是得寫(xiě)一段程序來(lái)檢查各個(gè)機構之前流程狀態(tài)以及當前位置來(lái)跳轉到相應的流程步，有沒(méi)什么好辦法或例程以及書(shū)籍提供一下不勝感激。關(guān)于報警，大一些的程序是不是都編多級報警？

買(mǎi)的許多書(shū)對此部分都只是寥寥數語(yǔ)帶過(guò)，這個(gè)邏輯老是繞不過(guò)來(lái)，能給于指點(diǎn)不勝感激。謝謝
