Overview

M-Bus is a master / slave communication protocol (EN13757-3) where the master initiates transactions and the slave(s) respond with the requested information or action. Data is transferred using hexadecimal telegrams.

The meter can communicate with your PC. In order to read out the meter registers first install and configure the PC software. Use an M-bus level converter to connect the PC and the meter.

The cable should be connected to terminals 10 and 11. The default communication address of the meter is 00.

The default M-Bus communication settings are as follows:

  • Baud rate 2400

  • 8 data bits

  • Even parity

  • 1 stop bit

The baud rate can be changed to values 9600, 4800, 1200, 600 and 300 baud. Data, parity and stop bit cannot be changed.
