Averaging measured values

With appropriate load profiles, consumers can carry out a targeted optimization of their
energy consumption.
Instantaneous values are averaged over specific time periods to create load profiles. For this
purpose, measured values are read out via the communication and stored. This
increases the bus load considerably and occupies storage capacity.
The PAC2200 device has two average value generators, which can be parameterized
independently.
The aggregation of the measured values reduces the bus load without risk of loosing
information. Average values are calculated contiguously, based on the underlying values.
The values are updated each time after expiry of the set time period.
The default setting for average value 1 is a period length of 10 seconds.
The default setting for average value 2 is a period length of 15 minutes.
The period length can be set to anything between 3 seconds and 31536000 seconds (1
year).
This function is only available if communication interfaces via Modbus TCP/RTU are used.
The list of available measured values can be found in the appendix A.1.4 „Modbus variables
with function code 0x14" on page 82 (Page 92).
