Configuration by the Telnet Console‎ ‎

Modbus Ethernet Gateways (G01 - G03 & G14 - G16)

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:

telnet <ip_address> <port_number>

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.

List of all commands

Modbus ports configuration commands

• modbus
  • modbus help
    Print command help.
    
    
  • modbus int_addr VALUE
    Set internal Modbus address.
    
    Example:
    modbus int_addr 5
    
    
  • modbus idlet VALUE
    Show or set the idle TIME (in seconds) of the TCP connection after which the TCP connection is terminated by the converter and the TCP socket is released.
    
    Example:

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").
