CI854 / CI854A Profibus communication crash
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 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).
