“Activate Proxi cache” parameter :
Enable the proxi option if you wish to avoid to frequent requests on the serial interface.

the serial interface.
“Timeout waiting for the answer” parameter :
Set up the timeout the gateway has to wait for the answer of the modbus slave.
“Local retry” parameter :
Set up the number of times the gateway will repeat a request to one of the modbus slaves on the
serial interface before declaring a failure.
“Inter-character gap” parameter :
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 :
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.
