Does the printed serial number on the energy meter match the one read through the communication interface?

FAQ #101835

 

Energy meters produced since June 2013 does have the same serial number on the front of the energy meter and read out over the communication interface.

This change has been implemented in all energy meter with production date 1322 or later.

This applies to one-phase and three-phase energy meters with S-Bus, M-Bus or Modbus communication.

Note also that the format of the serial number has changed for the S-Bus and Modbus (is now ASCII) and due of this it's necessary to use an aditional register to store the serial number.
The new used register was not used on the energy meters with production date < 1322.

Used register for the serial number on the different

Comm. interface		Prod.date <1322	Prod.date >=1322

Modbus	Register	16, 17	16, 17, 18
M-Bus	Byte	8, 9, 10, 11	8, 9, 10, 11
