Storage cycle Different storage cycles, ranging from 125msec to 32767sec can be
configured for normal, event and timed operation under “group configuration”.
The storage cycle determines the time interval for measurement storage.
Stored value Under this parameter, the value to be stored (average, minimum or maximum
value of the last storage period or instantaneous value) is configured
separately for normal, event and timed operation.
