The port information was the trick. I was able to send the output to the falcon controller and see the new sting vaules.
I was confussed as to the conrtoller connection details. Thinking it was on the setup tab, I redid the set up screen a few times thinking that was the issue.
As for the error message, is the error generaic for any detail fields missing or just the port field? Might help to add port field to the error message?
It makes sense now that I have filled it out and can see what it is being updated on the falcon controller.
Thanks all for your quick response and help!!
