Set up the maximum delay the gateway will have to wait between a
received character of a modbus answer frame on the serial interface and
the following character of the same frame.
“Modbus slave address* parameter :

In that case, each request sent by the TCP/IP modbus client to one of
the slaves connected to the serial interface must specify the modbus
slave address value in the modbus address field.
