Hello,
Just to a little bit reverse engineer things here - do you create manually the numeric control/constant and then pass some number? Just to be sure, try to right click the input and use create>>constant and then assign the value. Potentially there may be some conversion issue here.
How exactly are you viewing the console output? Display output should work. I am not sure about "Web based configuration and monitoring" via browser or "Console viewer" in VeriStand
