Modbus addressing

It is not possible to change the Modbus primary address of this type of meter via the context menu.

The default address corresponds to the last 3 digits of the meter serial number.

It is also possible to obtain the address via the meter's context menu. The counter below has address 73.


During commissioning, it is therefore necessary to note this number with the location of the meter and enter them in the portal.
