M-Bus
- Formal
-
M-Bus is a European standard covering remote readout of meters and can be used with different types of consumption meters and various types of valves and actuators.
- Practical
-
Data (e.g. heat energy) can be read out electronically. In that case, transmission is serial via a 2-wire line with reversed polarity protection, from the connected slaves (meters) to a master. M-bus meters are available for the acquisition of heat, water, electricity and gas.
