Use

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.

NOTICE

Forgotten password

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.

Functions

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.

Web server as master

Level converter as slave

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).

Web server integration in Synco IC

The web server activation key is entered on the Synco IC-Portal to register the web server

on the cloud. The activation key is available both via web browser as well as on the web

server display.

After registration, invoicing and trend data as well as alarm messages can be periodically

uploaded per settings and distributed to various users.

The Synco IC-Portal is located at: https://www.siemens-syncoic.com/.

Operating elements

The operating elements are used to navigate through the web server menu structure.

The device can be commissioned and current data can be viewed directly on the device

without a PC.

Additional operating options are available when accessing via PC/Internet browser.

Install the supplied antenna for the wireless application. The antenna can be connected

either directly or using a cable (recommended). Additional information on installing the

antenna is available in document A6V11157964. See Section Product documentation

[➙ 10].

LED

The LED indicates the operating state of the web server.

Display

Measured data and basic settings are displayed on an LCD display.

Press a navigation button to switch on the display. Access is password protected. The

display switches off automatically to save energy after 20 minutes.

Information is divided into four main menus:

●System info

●Wired devices

●Wireless devices

●Device search

●Settings

Topologies

Wired M-bus devices

The M-bus permits various network topologies. The M-bus devices and level converters can

be connected with the 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.

M-bus wired devices

Address

M-bus uses two types of addresses to recognize devices:

●Primary addressing: Up to 250 primary addresses can be assigned to an M-bus system.

The primary address is normally assigned during device commissioning.

●Secondary addressing: Secondary addressing consists of 8 bytes and permits the

assignment of any number. In the default setting, the secondary address for a device

matches the serial number issued by the device manufacturer. The assignment prevents

address conflicts on the bus.
