If the last transmitted value is 0, a measured-value change is transmitted immediately as a fixed zero-point
suppression value, see the following table.
Energy values are transmitted via MQTT as counter pulses. Additionally, in the OPC UA data unit, a conversion
factor
Energy per counter pulse
is contained in each transmission.
To calculate the primary value (energy value), the counter pulses must be multiplied with the conversion factor:
Primary value = number of counter pulses

pulse quantities
60 000 counter pulses per hour are recorded when V
rated
and I
rated
are applied to the device.
Aggregate
There are some restrictions when changing the value in the column
Aggregate
:
•
For operational measured values, you can select
0
(10/12 cycle RMS values) or
1
(aggregated values) for
each measured value.
•
For voltage and current harmonics, you can select
0
(10/12 cycle RMS values) or
1
(aggregated values)
for all harmonic values as a group. It is not allowed to have mixed selections for different harmonics
values.
•
For the harmonics power, only the 10/12 cycle RMS value is transmitted. The column
Aggregate
is
ignored.
•
For phase-related measured values, you can select
0
(10/12 cycle RMS values) or
1
(aggregated values)
for the measured values of phase A, and the selection applies to all the other phase-related values.
If you select
0
in the column
Aggregate
, the 10/12 cycle RMS values are transmitted. If you select
1
(aggregated values), in addition to the average value, the following values are also transmitted:
•
For operational values, the associated minimum values and the maximum operational values are
transmitted.
•
For harmonic values, the associated maximum values are transmitted.
You can configure the aggregation interval in

NOTE
All average, minimum, and maximum values are transmitted every time the aggregation interval expires no
matter whether they have changed or not. The time stamps of all aggregated values are identical and identify
the end time of the last aggregation interval.
