What is M-Bus? 

M-Bus (Meter-Bus) is a European standard for remotely reading gas, water, heat or electricity meters. 
The M-Bus interface is designed for communication over two-wire lines. This bus satisfies the special 
requirements for remotely powered or battery-operated meters. The meters send the collected 
measured values and data to a common master for further processing on request. 

 

Bus principle 

The M-Bus is based on the master-slave principle.  

Master = level converter (e.g. QA/S 3.xx.1 Energy Analyzer) 

Slave = M-Bus device/meter (e.g. ABB electricity meter from the A and B series, water meter, heat 
meter, gas meter, etc., with M-Bus interface).  

Up to 250 addresses (M-Bus devices) can be processed and polled in an M-Bus installation.  
The QA/S 3.xx.1 Energy Analyzer supports up to 16 or 64 meters, depending on the device type. 

The M-Bus master polls the individual bus addresses. The bus address is either the primary address 
1 – 250 or the 8-digit secondary address (generally the device’s meter number or serial number).  
The corresponding slaves/meters respond with a data telegram. The data received from the 
slaves/meters are saved in the M-Bus master (e.g. QA/S 3.xx.1 Energy Analyzer) for further 
processing. 

The primary address 

0

 is preset in the factory for M-Bus devices. The primary address must be 

assigned in the meter.  

 

Transmission speed 

The M-Bus is generally designed for speeds from 300 to 9600 baud. ABB meters from the A and B 
series can communicate at speeds of 2400 - 9600 baud. The speed must be set in the meter. 

 

Polarity 

The M-Bus interface is protected against polarity reversal, i.e. the wires of the cable used can be 
interchanged. 

 

Topology 

The M-Bus supports different bus topologies. The cables should be kept as short as possible.  
A combination of star, tree and linear structure is typically used to minimize the cable lengths. 

However, a ring structure is not advisable because a single fault can cause the entire system to 
become faulty. Furthermore, a ring structure makes troubleshooting more difficult.
