How do I initialize boolean indicators each time I run a program

[ringo42]

I am measuring voltages on protoypes and would like to be able to place a prototype in a fixture and hit "run" and see all my boolean leds go blank then either teh pass or fail light up accordingly as each test runs. This works fine the first time I open and run teh program, however if I hit run again the leds keep there old value until the test runs again instead of going blank first. They all have "off" as their default value, however hitting run does not make them go to thier default value. Is there a way to do this?
Thanks

The easiest way to do this is to create a Property Node for each indicator and write to its Value Property. Use the error out from the Property Node to cause these to run before the rest of your code through Data-Flow programming. Hope this helps.
