Why can't I see valid input data on Quantum analog inputs referenced to %IW1 - %IW8?
One possible reason is that Unity uses 8 IO Scanner Health words located at %IW1 - %IW8. Go to the Unity Browser and then to the Communication folder, there under the IO Scanner tab you will see the Health word assignments. You are free to change the starting %IW reference and valid analog input data should begin to appear on %IW1 - %IW8.
