Which products are affected?
8400 StateLine / HighLine with firmware version 01.00 or higher with fieldbus modules
What happens?

Although there is no reason for this error message, a Logbook entry is made. This is complicating the evaluation of the Logbook.
When does the problem occur?
If the CE04 error configuration is activated (C1501/1..2 = 1...6), an entry may be made to the Logbook / an error message may be issued at switch-on.
Possible diagnostics?
A Logbook entry is made although the error did not occur.
Short-term measures / recommendations?
None
Evaluation:
Only occurs sporadically under the described conditions.
