Ethernet to M-Bus communication converter

Basic Ethernet converter.

Designed for remote communication with M-Bus meters using the Ethernet computer network in building or home automation and similar applications.

The converter works only as a transparent gateway for transfer of M-Bus messages using TCP or UDP Ethernet protocols. Data is available only through M-Bus protocol readout. Data is available only through M-Bus protocol readout.

Main characteristics

The M-Bus converter features a processor controlled monitoring of internal state, power supply state and M-Bus line state. Operation and error states are indicated by status LEDs which simplify and make it easier to troubleshoot possible M-Bus communication errors.

M-Bus port

Connection of 1 to 20, 45, 80, 120 or 190 M-Bus slave devices depending on converter model.
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.
External voltage protection.
Processor controlled monitoring of M-Bus line state with LED indication for various error states.
Indication of M-Bus slave devices reply collision.
Indication of slave devices presence on the M-Bus line.
Indication of M-Bus line overload, short and capacitive overload.

Power supply

Wide range of operating DC power supply voltages 12-30V (20-30V for the XL190 model).
Overvoltage protection.
Processor controlled monitoring of power supply voltage with indication of its correctness and errors.

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 in server mode - option for multiple simultaneous connections.
TCP/IP connection in client mode.
UDP connection in single or multiple clients mode.

Software functions

Converter configuration through web interface.
TCP and UDP communication in server and client modes.

Differences from the EthMBus-XL SMART converter

No SMART functions for independent readout, processing and export of M-Bus data.
Lower power consumption.
Support for multiple connections in TCP/IP server mode.
Doesn't provide Telnet interface for configuration.
Doesn't provide logging of Ethernet activity and error states.
No options for backup IP addresses for establishing TCP/IP connection.

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.
