單一通道的故障
模件故障有硬性和軟性二種,需通過更換模件來解決的我們稱之為硬性故障,而通過對模件進(jìn)行復(fù)位可以解決的故障,我們稱之為軟故障,這種故障也有可能只反映在其中的某一個(gè)通道上,可以通過實(shí)際測量來判定。如2007年l月15日,#5機(jī)化補(bǔ)水調(diào)節(jié)閥不能開啟,無論DCS中給出的指令是多少,現(xiàn)場測量電流值始終為4mA。之后對該模件進(jìn)行復(fù)位后控制復(fù)正常。另有一次#4爐定排疏水電動門開啟且無法關(guān)閉?,F(xiàn)場檢查對應(yīng)的開關(guān)量輸出模件,第一通道輸出為“1”(對應(yīng)該電動門的開指令),而DCS中查看該通道的狀態(tài)為“0”,更換模件無效,對主控制器進(jìn)行下裝后控制恢復(fù)正常。
