cpu3152dp/pn上電半個小時自動停機。
現(xiàn)象為ledsf亮，同時cpu處于stop狀態(tài)，其它從站，2個et200m和em227模塊指示燈都正常。上電后再次重復(fù)。首先我把ob1里程序清空，還是會停機，說明我的程序沒問題。停機時候模塊指示燈都正常，所以請教高手指點，謝謝

診斷如下請大家?guī)兔Ψ治?br />diagnosticbufferofmodulecpu315-2pn/dp

問題補充：
首先謝謝半瓶醋。
我加進去了ob86和ob122，出現(xiàn)的現(xiàn)象是不停機了，但是sf燈還是亮
3號從站配置如下
ps3075a
et200m153-1aa03-oxbo指示燈正常
do16*24322-1bh01-0aa0有輸出
ai8*13bit3311kf02-oabo
ai8*12bit331-7kf02-oabo2塊，bf燈正常
ao8*12bit332-5kf00_oabo2塊bf燈正常

檢查了dp接線正確，但是屏蔽線割掉了，沒有壓到貼片上。

設(shè)備正在調(diào)試，只進行了數(shù)字量調(diào)試，還沒有進行模擬量調(diào)試，我該怎么去檢查，怎么處理？

從上述信息看，是機架故障：
、檢查模板的安裝，例如模板與機架之間的u型總線連接器、模板與前連接器的安裝是否緊固。
、檢查從站的通訊模塊或接口模塊的地址設(shè)定與組態(tài)的設(shè)定是否一致。
