Memory organisation
List of events
© Landis+Gyr
In the dedicated event logs, important information can be stored per entry
such as:

Duration of the events

Extreme values of the events (not for missing voltage).

Instantaneous values

Maximum three energy registers
Additional information can be read from the header of the event logs, such
as the longest entry, the shortest entry, the total number of occurrence and
the total duration of the event.
The dedicated event logs are organised as circular buffers, i.e. the oldest
entry will be overwritten by the most recent entry.
The table below lists all events which can be captured in the event log.
Depending on the parameterisation, some events may never occur.
Events which can be stored in the dedicated event log are marked in the
corresponding column.
