EthMBus-5 SMART, X-Port line
Ethernet to M-Bus communication converter
|
|
|
Converter for SMART metering
Designed for remote communication with M-Bus meters using the Ethernet computer network in industry and building automation.
In the Smart M-Bus mode the converter works as a server.
It communicates with the M-Bus meters independently, processes their data and stores it in its own memory.
The meter data is simultaneously available in form of:
- table on a webpage
- xml, xml(REST) and csv export
- M-Bus protocol communication
- e-mail with attached xml, csv exports
- exports uploaded to an FTP server
In the basic mode the converter works as a transparent gateway for transfer of M-Bus messages using TCP or UDP Ethernet protocols.
Main characteristics
M-Bus port
- Connection of 1 to 5 M-Bus slave devices.
The most commonly used devices are heat, water, gas and electricity consumption meters.
- Surge protection warranting above standard level of protection against overvoltage.
- Current protection against overload and short circuit on the communication line with
LED status indication.
Power supply
- Wide range of power supply voltages. DC 9-39.5V or AC 9-27.5V.
- Overvoltage protection and resettable current fuse.
- LED power supply indication.
Ethernet
- TCP, UDP protocols and virtual COM port software.
- 10/100BASE-TX ethernet port, RJ45 connector.
Mechanical construction
- Aluminium box with mounting on 35 mm DIN rail.
Main software characteristics
Transparent gateway mode:
-
TCP/IP connection
- server or client mode
- backup IP addresses for connection
- connection to a web address (DNS)
- UDP connection
|
|
Smart M-Bus application mode:
- web page with meter data
- xml, xml(REST), csv exports
- e-mails with exports and service information
- exports uploaded to an FTP server
|
|
Software functions
- Configuration of the converter through a web interface or Telnet.
- TCP and UDP communication in server or client mode including
connection backup IP addresses.
- DNS support (host name instead of IP)
- Logging of Ethernet activity and error states.
- Search for meter addresses and their change (meter must support this functionality).
- Success rate statistics for communication with individual meters.
Differences from the EthMBus-5M SMART converter
- More powerful overvoltage protections on the M-Bus line and the power port.
- More powerful M-Bus line driver with more efficient filters. The length of the M-Bus line can be more then 1km.
- Wider range of operating temperatures.
- More robust mechanical construction.
References
In between years 2011-2018 more than 600 units of the Ethernet to M-Bus converters have been deployed in cooperation with the company IPECON s.r.o. for several custommers in Slovakia and Czech Republic. Converters were used to collect data from utility heat meters into SCADA systems.
Guarantee of quality
- Each converter passes through several functional electrical tests during the production.
Additionally a communication test is performed after final assembly.
- EMC certification in an accredited laboratory for industrial environment.
- Solid design and construction based on many years practical experience.
- Converters deployed with trouble free operation in various applications since 2011.
