Using a V130 configured for TCP I am using an external device to continuously poll the state of a blocks of registers.
This works fine for several days but occasionally will simply stop responding to modbus requests. I can ping the V130 and connect to it using Visilog so I know the IP address is setup correctly but no modbus activity is possible. Once I reboot the V130 everything works until it stops responding again after a few days.
Any suggestions on what I should look for would be much appreciated.
These are the TCP setup rungs
