NOTICE

Forgotten password

The M-bus web server reads devices connected directly to the web server, devices
connected to the web server via level converters as well as devices connected to the web
server via RF converters.

Web server can be used:

● Alone with up to 20 directly connected, wired M-bus devices

● As a master on an M-bus network with up to six connected level converters, each with up

to 60 M-bus devices and/or

● As a master on an M-bus network with up to 23 RF converters, each with up to 500 RF
devices

The web server can read out up to 2,500 wireless devices and up to 250 wired devices. It
records the data from the connected M-bus devices, can evaluate the data, and sends email
notifications on events and alarms.

The device storage can save data for a period of max. 10 years (data is read once a day).
A PC/Internet browser reads the data and log files either locally over Ethernet or from

anywhere over the Internet. In addition, the report files can be periodically transmitted with
device data to an email recipient or to an FTP server.

In the event a password for web server access via an Internet browser is lost, it can no
longer be reset or requested. The web server must be replaced.

An email can be sent on events and alarms.
The web server can be integrated in the Synco IC-Cloud. This permits the periodic upload of

invoicing and trend data as well as alarm messages to the cloud per customized settings as
well as distributing the information to the corresponding customers via email.

The web server has three digital inputs and two digital outputs. The change of state to inputs
or outputs are recorded in the event log and/or per email depending on the configuration.
Both outputs can be manually switched via web operation.

Web server is protected against short circuits and surges.

M-bus web server for reading wireless devices

The web server can be used in various ways:

The web server reads up to 20 directly connected devices
(20 unit M-bus loads).

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.

Web server as master

Level converter as slave

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).
