800xA for Advant Master ; All Client and Server are not communicating with only one AC450 controller out of 9.
Please review this problem.
In 800xA for Advant Master S-FP 5.1.1-1 RU1 (rollup on 800xA 5.1 FP4 Rev D) June, 2015. At that time, we thought that MB300 backpressure may be root cause for Alarm and Event problem.
Similar problem was happened. There are 9 controller in the system. The operator found out no live data in only one controller of them. The graphic symbols for the controller was all gray color and no data. The last of the controllers are all good in 800xA System.
When the maintenance guy rebooted the Primary connectivity server first, there is nothing happened. After Primary Connectivity server became normal, he rebooted the secondary connectivity server. Then all the data for the controller came back.
Checked out the system event. But there is no relevant information. No window system and application event, too. This seems like special case. What I could not understand is the last of them are all good except one.
How could this happen? Could anyone tell me any probable explanation and way to fix it?
I've tried, but without any more details from you I can not say so much more.
- System messages?
- ANPER results?
- OPC statistics?
- System events from 800xA
- Configuration drawing of site, application, data subscribers, etc.
I recommend that you file a support case with your regional ABB support center, It's limitation and difficult to provide support via text only from this forum.
