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.
