If a trend signal at the local inputs is no longer available (e.g. due to a faulty
sensor), trends are no longer recorded.
In this case, observe the messages under:
Main menu > Faults > Faults current >
If the values are not available via bus, trends are no longer recorded.
After a power failure or when exiting the "Extra configuration" menu (restart
controller), the values of the 8-hour and 8-minute views are deleted.
However, the values of the 24-hour view and those of the last 6 days are retained.
