- Port: UDP port of the controller where requests are sendsent.
Note: The parameters of the backup server (Host and Port) are not used in this protocol.
...
- Communication protocol: Remia E3.
- Station The station address is set according to the address on a device (0 to 15) specified as a decimal number or as a hexadecimal number with a hash at the beginning (e.g. #6A).

You can obtain also the values from an archive of
the device
per for the current and previous month for both the main and secondary measurement. The reading of archive values may be started in the station dialog box or by
Tell the GETOLDVAL Tell command
