1)
The threshold value in unit depends on the last value transmitted to the MQTT broker.
2)
If the last transmitted value is 0, a measured-value change is transmitted immediately with a fixed zero
-
point suppression value.
Threshold
For the transmission of 10/12 cycle RMS values and harmonics, a threshold processing is executed based on
the following thresholds and method:
•
The thresholds related to the last transmitted value
•
A combined fixed and integrated threshold method
Threshold [%]
Point value
The threshold value in percentage

Zero-point [Unit]
2)
Point value
Zero-point suppression value in unit

0 = 10/12 cycle RMS values
1 = aggregated values
This column shows whether the data point is published as
aggregated values or as 10/12 cycle RMS values with
threshold processing.
