14.4.1 Functional description
The structure of the logbook corresponds to a ring buffer:
[14-3] Ring buffer structure
14.4.2 Filtering logbook entries
The logbook enters new entries in the ring buffer after they have passed through a parameterisable
filter. By means of this filter you can exclude events with a specific error response (trouble, warning,
information, etc.) from being entered in the logbook.
The filter is parameterised in C00169 by means of a bit mask. A set bit inhibits the entry of the
corresponding event in the logbook.
• The option that identical consecutive entries ("multiple entries") into the logbook are
suppressed can be additionally activated via bit 0. Then only the time stamp of the last (latest)
entry and the number of times the same event has occurred successively are saved.
• As long as free logbook memory is available, the entry is placed in
the next free position within the memory ().
• If all memory units are assigned, the oldest entry () is deleted for
a new entry.
• The newest entries will always remain available.
