CI854 / CI854A Profibus communication crash
Hello
During about one year our customer has changed 2 times CI854A.
Because Profibus communication has stopped.
Are there some hardware troubles between some serial numbers / production time of CI854 / CI854A ?
If any, could you inform us.
Our customer’s CI854A modules has delivered about 2013…2016.
I have investigated matter using “ https://library.abb.com/ “ and “ https://forum-controlsystems.abb.com/ “.
I can find only (many) Firmware and Control Builder / Compact Control Builder version matters and instructions.
Also other our customer has similar troubles.
System delivery year is 2014.
Sometimes Profibus communication stop.
They give power off / on “reboot”, and after that, communication coming ok.
Until communication stop again (later).

We have had a similar problem, see the attached product alert.
I'm not quite sure for further solution, but we fixed the problem by changing of CI854A with the newer one and loading of the newer firmware to it.

That's not enough information you should try to collect System Events and Controller Logfiles for those incidents, assuming the CI854 goes to Error State something should be logged. There is also Diagnostics available on the Controller Web Interface.
If this issue is important for you, contact automation supportline with those informations.
