We introduce to you a modern communication converter intended for connection of industrial M-Bus devices to the Ethernet, using the LAN/serial interface module XPort.

Usage

The communication converter is used in industry and building automation for data acquisition from heat consumption meters, flow meters, power consumption meters etc. It supports a connection of 1 to 5 M-Bus slave devices and a bus with devices connected can reach up to a few hundreds of meters length, depending on a connection quality, communication speed and additional protections. Connection of the interface module with a PC application can be realized by a virtual COM port, or directly through a TCP/IP connection. Connection through a virtual serial port is suitable for older programs, suitable only for a serial communication interface. Configuration of the interface module is possible via a password protected web interface.

Main Features

A construction of the interface module is based on practical experience from implementing of communication interfaces in an industrial environment. In order to reach a high reliability and immunity, the module has an above-standard protection against overvoltage. M-Bus port is resistant to a continuous shortcut, overload and it contains a filter increasing the resistance of communication to disturbances. M-Bus port is galvanic isolated from power supply, as well as from an Ethernet interface, to ensure a high overvoltage immunity and it prevents ground loops creation. A range of a DC and AC power supply has a wide range and the power supply port has an overvoltage protection, as well as a self-resettable PTC current fuse.. The module is in a robust aluminium enclosure, with a possibility of mounting to a 35mm DIN rail. For a simple assembly and replacement is the connection of leads realized by plug-in connectors. Operation statuses are indicated by six LEDs for a quick detection of an actual module status, its work and an indication of possible communication errors. The „overload/short“ LED diode differs two basic M-bus link error statuses. A shortcut is indicated by a continuous light and an overload by blinking.
