CI854 Error?

Hello,

From time to time I get a strange error on 2 different controllers with redundant CI854 interfaces.

For some reason the backup card fails for a few seconds. After that it comes up again and looks "normal" (without any error).

I attached a screenshot and a controller logfile for details.

Could it be that these CI854 are from a bad series? (Used System is 800xA 5.1 Rev. D, the latest Firmware is installed)

regards,

Michael

Hi,

3 Months back, i was facing the same Problem. The following things were done. If it helps you, it will be good:

1) Tightness of all modules in CEX bus where checked.

2) CI854 modules were replaced & firmware upgraded to corresponding version.

3) All Profibus connectors were checked in our site using Profitrace tool.

4) Earthing of IO panels were checked.

Try to cover these points..Your Problem should be rectified..

Unfortunately, in our site the problem was not solved despite following the above points.

Now Baudrate of CI854 is reduced after which the problem has not repeated still.

In case of these problems, its difficult to give a fixed solution. Try to follow steps sequentially. Get assistance from ABB Regional Support..
