Connection drops with PLC SIM Advanced 6.0 Update 1

Cheers,

One of my guys is working on a training module we developed, and is having a connection stability issue with PLC SIM Advanced 6.0, Update 1.

We are able to get him connected, and after a min or 2 we get the comm error 509. Put/Get is enabled, full access is given. It’s weird, we’ve had a few others go through this, but never had connection issues. Then we reconnect, and it does it’s thing for a min. Then same issue.

Everything has been run and installed as administrator, just kind of at a loss right now.

Open to any suggestions anyone has.

Thanks.
