I tried the latest TCPIP driver, 6.2.0.3 and with it I can go longer communicate with UDP devices. I have several devices communicating using DNPR over ethernet and some are TCP and some are UDP. These have been communicating fine for a long time. When I tried installing this latest TCP driver (no other changes) and restart my project, the devices that are UDP are offline and do not come up. I did a quick wireshark logging and can see the UDP messages going out and responses coming in.
I do not see anything in the associated readme about UDP changes and there is no other driver documentation that I can find. I removed the driver and re-installed the older 5.01 and all comms are back up as expected.
Thanks
