Explanation
Summertime switching, setting the time
Shortened registration period due to power failure or time change
Parameter change
Alarm or error message (collective message)
All warnings and device faults
Exception: Warnings 03/02 "power dip" don't stored (from version
1.04.03 up).
Transmitted during summertime (MESZ)
Unused
Power failure during the whole registration period
Unused by default
if enabled via DLXPARA: change of state of LOG control inputs
Default value $40 (hexadecimal notation);
only if enabled via DLXPARA: rate status AT-MT, however only the
energy rate (if energy values are transmitted) or the demand rate
(if demand values or energy increments are transmitted) will be
set.
