You can put whatever code you want in any event structure.
Here is the same file uploaded by mike, but instead of a timeout case for the main code, I put a button called "Display New Vlues" that handles all the calculations.
Edit: Lol. just saw mikes msg pop up after i added this
your last VI is very suitable to my data...thank you very much... It's a excellent idea to trigger the activation of the pane when LED 1, LED 2, LED 3, LED 4 had their state changed. The only additional thing that I need is that after the file is loaded, the SUM result appears without any "click" on the LEDS. I try to trigger the pane with other things but I got no success and only when a LED is "clicked" the pane runs. Which element I could associate do the trigger of pane?
StevenD.... your VI answer another question....!!! The use of button to display LED modifications... thank you
to do it, change one of the local variables with a property node of the changed LED, and select the "value(signaling)" property. If you do it, the "calcualtion" event will run after you load a file. See the attachment.
