5.4.4 Error List and Logbook
The administration of events and errors is a functionality provided by the
Basic System. Its main display, the Error List, can be evoked by activating
the button labeled Error List in the device's home display.
At first, the Error List display shows all errors, i.e. all alarms and warnings
that are currently pending or waiting for acceptance. There is a filter option
for displaying errors of single function blocks only or of function blocks that
are grouped by parameterization.
