Connection for All Makes of Consumption Meters: M-Bus

The M-Bus – An Inherently Cost-Optimized Fieldbus

The M-Bus system, based on a master/slave communication model, can be operated as a line, star or tree topology. The master powers the serial bus and processes the data of the M-Bus slaves (measurement devices).

M-Bus in Brief:

  • A single bus cable connects all meters to a central system.
  • Select bus nodes are supplied directly via the two-wire bus.
  • Devices from different manufacturers can be connected to a bus system, which does not bind users to a meter manufacturer.

M-Bus Simply Explained

The M-Bus (Meter Bus) is a cost-effective fieldbus for transmitting energy consumption data. A central master – in the simplest case, a WAGO controller with downstream level inverter – communicates via a two-wire bus (up to max. 250 slaves per segment) with bus devices (e.g., heat meter, water meter, electric meter, gas meter), as well as all sensor and actuator types.
