Configuration by the Telnet Console

Modbus TCP/RTU M-Bus Gateways (G20, G30)

The device can be also configured via the Telnet Console. Firstly, make sure that converter is connected to the power supply and to the LAN using a patch cord. Knowledge of the device’s IP address (default is 192.168.100.100) and Telnet port number (default is 23) is necessary to establish a connection.

Use command below in a terminal window to connect to the device:

If the connection is successful there will be login prompt visible. Login using user's personal credentials or the default login details (login: admin, password: admin123). If login is successful, it will be possible to start typing configuration commands.

The configuration is available only if devices are connected to the same Local Area Network as the computer used for it.

M-Bus ports configuration commands

• mbus {com_number} {subcommand} [arguments]
    Print or change mbus_ports configuration
    com_number - COM port number, as labeled in device's manual, to which mbus applies. This field is ignored for the                       subcommands 'period', 'availability' and 'help'
    subcommand - subcommand to execute
    arguments - subcommand parameters

  • mbus mode [MBUS/MODBUS/DISABLED]
        Sets port mode.
        MBUS - Operates as an M-Bus master polling slave devices.
        MODBUS - Acts as a Modbus slave, providing access to MBUS register data.
    
    
  • mbus add_slaves [SLAVE_ADDR ;/- SLAVE_ADDR, *][]
        Sets all addresses of slaves connected to com_port.
        A star in value means fill rest free slaves. It means all slaves that    are not set to other ports will be set to this one.
        Example: mbus 1 add_slaves 124
        Example: mbus 1 add_slaves 12-124

        Example: mbus 1 show_slaves
    
    
  • mbus baud [RATE]
        Sets the baudrate to RATE. For a list of acceptable baudrates please
        refer to manual.
        Example: mbus 1 baud 9600
    
    
  • mbus bits [PS]
        Sets parity to P and stop bits to S. Valid values are:
          P: N, E or O
          S: 1 or 2
        Example: mbus 1 bits N1
        Example: mbus 2 bits O2
    
    
  • mbus data
        Show data at desired address. 'com_number' is an address of MBUS slave
        Example: mbus 4 data
    
    
  • mbus period TIME
        Sets the period of readouts from the slaves to TIME [in seconds].
        A TIME value must be in range:
          1-4294967295
        Example: mbus period 30
    
    
  • mbus resp_to TIME

Additional notes

After some time of inactivity, session will be disconnected automatically.

In order to avoid issues like connecting to host, type “help” to get more information.

To get more details about every particular command, append “help” after each commands (example: "ipconfig help").

Factory reset is not available from the Telnet Console level.
