Initialization of LEDs prior to running second test.

[chuck72352]

I'm am a novice Labview programmer using LV 8.6.  I have an appication where I have many LEDs to indicate pass or fail throughout my application in different Case numbers. After running the test those tests that passed are indicated on the front panel with a green lighted LED. Those tests that failed are lighted with a red LED. Is there an easy way to initialize all the LEDs back to their off state prior to running the test a second time without reloading the application?

Use local variables for your booleans. Connect a false constant to them and put that either after all of your code or in an event structure. It depends if you want a button to reset them from the front panel, then the next test to begin, or if you want to reset them programmatically before the test excutes again.

Heres a quick example. First the boolean values are changed to true, then they are reset to false. Does this help?

Your solution works great!

I would suggest using invoke nodes "reinitialize to default" instead.  Using local variables can be messy and can cause race conditions.

I'll give it a try as soon as I get familiar with invoke nodes.

Thanks!
