Hello all,

We were trying to just get a feel for Ignition and have followed the steps to add our processor and tags to the ignition designer. However, the screen shots show what I am seeing. You go to bind any tag to an object, and it simply shows error. Thats nice that it instantly shows you something is wrong I might add. I went back and watched the video on setting up the device and I have it configured properly. Any help would be greatly appreciated.

Thank you
