Operating modes
The web server can be used in various ways:
M-bus web server with wired M-bus devices
The web server reads up to 20 directly connected devices
(20 unit M-bus loads).
M-bus web server with level converter
The web server is equipped with additional level converters to extend the system by up to
250 devices (250 M-bus loads).
The web server is operated as the master. Up to 20 M-bus devices can be directly
connected.
The level converters are connected as slaves to the web server. Up to 60 M-bus devices can
be connected to each level converter.
Up to six level converters can be connected to the web server.

M-bus web server for reading wireless devices
The web server is equipped with additional RF converters to extend the system up to 2,500
wireless devices. The communication between the web server and RF converters takes
place over a mesh RF protocol (backbone network).
A minimum of one M-bus web server and one RF converter is required to read out wireless
devices. The backbone RF network can consist of a maximum of 23 RF converters.
Communication between the RF converters and wireless devices takes place over the
wireless M-bus protocol. The RF converter saves the consumption data from the devices in
its environment, while forwarding the data to other RF converters, up to the web server (the
other RF converters act as repeaters here).
