(Meter-Bus)
Use
The M-BUS board serves as the MASTER interface of the physical layer of the M-BUS for the application
of data collection from meters regulating the consumption of various types of media (water, gas, heat,
etc.).
A M-BUS module can be positioned in the first or second slot of optional modules, see section Sec-

Section 3.10, “Service Connector”.
For the correct operation of the module it needs to be configured to the proper SCC in menu SPe using
