The DP station with the station number listed in the detailed information has failed (event 39C4) / is operational again (event 38C4).
Possible causes:
· The DP station was switched off/on.
To correct or avoid errors:
Check the status of the DP station.
The cable to the DP station was disconnected/connected.
To correct or avoid errors:
Check the cable to the DP station.
剑工 以上是我在help on events上查出来得。还是不明白。我得再研究研究,呵呵。

我做的一个系统出现了一些意想不到的问题,给剑工打了电话,谢谢他的解答。
我用3152DP与266CN通过EM277组成Profibus网络,遇到如下问题:
首先我在STEP-7中组态没有问题,277的拨址开关打到的位子也是对的,连接的电缆也是西门子的紫色电缆。
1.从站EM277的DX MODE灯不亮。
2.在STEP7中监控不了这个从站的数据。
3.曾经在step7 microwin 的PLC信息中找不到EM277,出现故障的时候能看到。
4.266是CN型的
5.更换226就好了
6.第二天277的DP ERROR灯亮
7.更换一块EM277,又好了
8.一个小时以后DP ERROR又亮
9.226与277中间有一块EM235模块,去掉235 ,直接连接266与277,又能正常通讯了
10.PLC与一台90KW的ABB变频器安装在同一个控制柜的。由于控制柜小,动力电缆,控制线,通讯线混装在一个线槽里面的。
11.PLC、变频器共地
12、换下来的277、226均是好的。
剑工提议从以下一个方面排查:
1..把step 7 microwin 升级到SP6
2.更换226的电源(因为PLC与ABB的变频器共用的是一个电源)
3.plc与变频器分开接地
4.动力电缆换成铠甲电缆
现在在从第一个问题排查
