propertynode !!

[college123]

Hi!

I have made a vi. of blinking LEDS using property node. Then I have used this vi. as a subvis in other vi.s But when I run this program the leds doen't blink in main vis. but it blinks in subvis.

 so how to link this vis. to main vis so while program runs leds should blink.

thanks

Create a reference to the boolean in the main VI and feed it to the subVI (create a connector for it on the subVI connector pane).

In the subVI, wire the reference to the property node so it knows what indicator you want to modify.

Thanks for your reply.

I am sending you main. vi and blink.vi (subvi) files.

let me know where i will have to change so i can make main vi blinking

thanks

I would strongly recommend doing some tutorials to learn the basics of LabVIEW. The code images you posted don't really make a lot of sense.

Why do you even wire the LEDs? Their value never changes!.

Here's a very quick example (LabVIEW 7.1) how you would change the blink property via a subVI using a reference.
