M-Bus

European standard for the remote reading of water meter, gas or electricity meters.
uses 2 wires for communication
Wireless M-bus (circular link) veriant is also available
An alternative method of collecting data centrally is to transmit meter readings via a modem.
- modulator-demodulator
- is a hardware device that converts data into a format suitable for a transmission medium so that it can be transmitted from one computer to another (historically along telephone wires)
Other applications for the M-Bus such as alarm systems, flexible illumination installations, heating control, etc. are suitable.
Since the M-Bus is not a network, and therefore does not - among other things - need a transport or session layer, the levels four to six of the OSI model are empty¹.
Only the physical, the data link, the network and the application layer are provided with functions¹.
