10.19 Logbook
Description
The logbook contains a chronological list of trips, device faults, and events,
which are assigned a time stamp and can be used to create a log. This log is
then saved internally. This provides the possibility to evaluate the causes later.
Logbooks
Three types of logbook are available, which can be read as data records:
• Logbook – trips: data record 73
• Logbook – events: data record 75
• Logbook – device errors: data record 72.
Device errors are entered.
The current 'Operating hours - device' value is entered as the time stamp.
The last 21 entries are stored in the logbooks. The entries can be read with the
relevant data records.
The logbook is designed as a circular buffer. When 21 entries have been made,
the next entry overwrites the oldest.
