I don't understand what you're trying to do. You can't use the LabView application to track the target light. The tracking software runs on the Robot Controller.

If you're using the marvelous code from Kevin Watson, there are macros which define the pan and tilt directions. Change the sign of the appropriate one to make the camera seek instead of avoid the light. (I don't know enough about the EasyC function to tell you what to change in it.)
