各位好,今天PLC317 -2 pn/dp碰到了个故障信息如下:
Event 1 of 10: Event ID 16# 3858
PROFINET IO: The status of a submodule has changed from bad to good, initial values for outputs can be set
station number: 2
IO system ID: 100
Input address: 1600
no relevance for user (Z3): 8101
Requested OB: Remove/insert OB (OB83)
Priority class: 26
External error, Outgoing event
08:36:08.635 AM 09/02/2013
上面这个设备是PN/PN coupler.前几天设备是正常的,现在设备也能正常运行,但是PLC一直有这个故障。是不是由于通讯原因
不知道各位是否有遇到过,是什么原因?谢谢
