“Modbus slave address* parameter :
If only one modbus slave
device is connected to the serial interface,
set the modbus address of the device; any TCP modbus request
received by the gateway will be sent on the serial interface using that
modbus address.
If several modbus slave devices
are connected to the serial
interface, select “specified by modbus TCP client”;
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.
“TCP inactivity Timeout” parameter :
Set the time the gateway will wait before disconnecting the TCP link if no
characters are received.
“TCP port number” parameter :
Set the port number the gateway has to use.
