Hi Oleg I wanted to be clear about which method to use when passing values between main and subVI. My program will have a main VI which will be consisted of few subVI's. Take for example one of the subVI's, the multi-gauge instrument that measures the pressure. If I want to change the units of the pressure from Torr to Pa I am using enum inside of subVI. Now when main VI is running and the user changes the units on the front panel of main VI do I use reference of my enum or global variable method you described or some other method?
What is the best way of passing data from main to subVI in general? Thanks, Pedja
