4.18.3.1 General information
The X20 system is now being expanded to include a new M-Bus master communication slice. This single-width
module can be placed anywhere in an X20 I/O system and can therefore be used as a decentralized solution in
distributed topologies. The M-Bus master supports transfer rates of 300, 2400 and 9600 Bit/s and up to 64 slaves
can be connected and supplied via the M-Bus.
The M-Bus (meter bus) is a relatively simple fieldbus for collecting consumption data, such as from electricity or
heat meters. It is based on reverse polarity proof two-wire connections and uses the master-slave principle.
