Runing at the same time two routines sidebyside in single VI

[Sharjil]

I want to run two routines side by side in a single VI at the same time....how can i do this..???

[Dennis_Knutson]

Put them in separate while loops.

[Sharjil]

But they wil be running one after another, the thing i want to perform is to run two while loops at one time...

[Dennis_Knutson]

The only way that they will run one after another is if you have data from one loop wired to the other loop. If there is no wire between them, they run in parallel.

[Sharjil]

Is there any way of putting the things as ...

Two while loops are executing in parallel, with connections, one loop executes and the other waits for a value from the first while loop to arrive, it executes that value and now again waits for the value from first loop to arrive, another thing to add is that when the first loop gives a value to the second loop, the second loop should accept that value at once and start executing the loop with that value.

Hi Sharjil

The Producer Consumer Desing Pattern is what you are looking for.

Search the forums for this term and you will find various threads.

Hi Sharjil,

The producer/consumer pattern is exactly correct.  You can view a template for how this can be done by opening LabVIEW to the "Getting Started" splash screen.  You then click on "more" in the New Files section.  Go to VI>>From Template>>Frameworks>>Design Patterns>>Producer/Consumer Design Pattern (Data).  You can use this template with its queues to send data between two loops that are running in parallel.  For more information on this architecture, check out

Thanks and good luck!
