tton to see the program running, and it passes the data to the subVI, but subVI does not return anthing. A Green Arrow ---> shows and gets hung for ever. I am using the PCI-MIO-16XE DAQ. When I run my SubVI as main VI it works just fine. Any suggestions?

You dont say what your subVI is doing or the make up of your subVI. But if it works when you run it on its own and doesn't as a subVI, it could be that you are not passing the correct values via the subVI's connectors.

When I run my SubVI as main VI it works just fine. Any suggestions?Hello, The subVI is acquiring data, plotting it and giving me 5 calculated results based on the data acquired. I am using 4 channels in the DAQ card, so I perform math on them and spit out the result. I am passing Device,channels,Scan rate, a constant value, and Samples/CH, which is what the VI requires when it is running by itself.
When I make it a sub-vi I pass the same data, and as I push on the SubVi I can see the values being calculated and spitted out, but my main VI does not pick those values. I wonder why!

I believe that it would be valuable if you could include your vi to the posting.

When I run my SubVI as main VI it works just fine. Any suggestions?As I played more with the vi I realized I had a while loop in the subVI so it loops forever in that VI. SO I removed the (NOT GATE) and placed a False statement so it exits the loop. Since I am looping in the main VI then it now passes the data to the main VI.

Thank you so much!

Or perhaps you could run in highlight mode and enter the subvi with the arrows, so you can see the whole proccess, not only your vi's proccess (with the green arrow on the subvi...). But I really think that you could post an example reproducing the problem so that we can help you further.

It seems that when you call & execute sub vi in your another program, sub vi shows a green arrow that means your sub vi has gone into some looping out of which it is unale to exit. So check your sub vi which should come out from its task after you define or after it executes the task defined inside it.

Better attach your VIs so that it can be checked & modified.

I hope Robert hasn't been having sleepless nights over the problem for the last 2 and a half years! ;D
