WIZ107SR time out retransmission

S2E Module WIZ107/108SR
1

Hello,
I am using a WIZ107SR to make a modbus connexion.
This works but there is lot of time out retransmission because the client send a ack 200ms after a request .
If the client send a ack in less 199ms, it’s ok, else the WIZ107SR send a TCP retransmission.
IS it possible to adjust the time out retransmission ?

Thanks

Hi, philippe456.
Unfortunately, the WIZ107SR don’t provide TCP timeout value adjustment functions.
In general network environment, the client can be respond a more faster i think.
Any special reason for late response?

Regards,
Eric.

Hi
thanks for your reply.
I was testing WIZ107SR with windows 7 and modbus doctor.
I don’t know why the reply is done 200ms after !
Best regards.
