What happens?
Although there is actually no reason for this error message, a
logbook entry is made.
This complicates the evaluation of the logbook.

When does the problem occur?
When the CE4 error configuration is activated (C1501 / 1..2 = 1...6), a logbook entry is made / an error message is output when the devices are switched off.
Short-term measures/recommendations?
Supply fieldbus modules with an external 24V voltage.

Evaluation:
Only occurs at switch-off, not during operation.
