how to stop a second while loop when the condition in the first one is met for different VIs

[alexanderrose20]

Hi, am running two seperate Vi's. am new to labview so please help accordingly.

I have introduced a comparison test  in one Vi through ashift register. i would like now the second Vi to stop when this comparison condition in the first Vi is met. 

I dont want the first Vi to stop, it should only stop the second Vi while awaiting for the next input.

waiting for your help guys

Hi alex,

you could use notifiers. Or queues. Or even a local variable of the second loop's stop condition…

Hi!

Its hard to tell exactly what you need, since we dont have your code. But in general, you need some kind of synchronisation mechanism. You can for example use, notifiers or ques.

Have a look at the supplied examples that comes with LabVIEW (or check out the produce/consumer template).

Hi Alex,

now I clearly suggest a notifier…

And I suggest too to reduce the usage of local variables (and "value" properties) to a minimum…

Thanks GerdW,

I would too like to reduce on the property nodes,  but this is the program from the manufucturer that comes with the device, am trying my level best to adjust it to fit my needs. so many case structures interlinked with the property nodes. this has been my challange too. 

But thanks for your advice

best regards
