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:

    • modbus_ports PORT_NUMBER add_slaves [SLAVE_ADDR ;/- SLAVE_ADDR, *]
      Set 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:
