Wired M-bus devices
The M-bus permits various network topologies. The M-bus devices and level converters can be connected to the M-bus web server in a line, bus, star, or tree topology (or a combination of topologies). The same applies to connecting M-bus devices to level converters.
Ring topology is not permitted.
Bus cable polarity is not relevant, simplifying installation.

Wireless M-bus devices
The M-bus IoT gateway supports various network topologies for RF read out. The RF converter is self-organizing and searches for the optimum connection to the gateway (mesh network).

Network nodes with cable connection to the M-bus IoT gateway
The M-bus IoT gateway can read out up to 5 networks in parallel. Each network node has access to all consumption data on its own network (mesh network). At least one of the WT.. network nodes must be connected to the gateway using a physical M-Bus line.
