The information in this page is updated in accordance with firmware version TRB1_R_00.07.07.2.

Summary

The M-Bus (Meter Bus) is a cost-effective fieldbus communication protocol for transmitting energy consumption data. A central client – in this case TRB143 – communicates via a two-wire bus (up to max. 250 servers per segment) with bus devices (e.g., heat meter, water meter, electric meter, gas meter).

This manual page provides an overview of the M-Bus functionality in TRB143 devices.
