2.4 Modbus Mapping Area
The data read from the meters are placed in the Holding Register area.
A copy of the values is also present in the 4x20000 holding register area.
Refresh time of the values is approximately 3 seconds.
Modbus addresses in the table are base 1; depending on used Modbus master, sometimes is required
to swap words to read data correctly.
