Parallel While Loops Ni Community I'm trying to have two parallel while loops running in my labview vi. the top while loop works as it should, plotting portions of my incoming data frame. the second (bottom) while loop i am trying to grab the audio data of my frame which is the 3rd and 4th byte of the packet and write this to a .wav file.

Parallel While Loops Ni Community Running multiple while loops in parallel with each other is a pretty common practice, especially for simple applications such as this. now if you need to control the timing of a certain operation between multiple loops then you'll have to get more creative. Use two while loops. inside each of them put a event case. one to handle the "c=a b" event and one for the "loop value changed". i think the design pattern you are looking for is the producer consumer pattern. this allows you to run parallel loops and if need be share data between them. I made this article for those who are new to labview in order to quickly understand how you can run tasks in parallel using ni labview. labview makes that super easy which programmers who are experienced with other languages find daunting even using latest integrated development environments. Control loop are data in parallel loops. this is a direct consequ e of data flow programming. there are, however, techniques for exchanging data betw loops running in parallel. one way to do is is with local variables. right click on the vertical indicator icon in the block diagram.

The following illustration demonstrates transferring data between two loops running in parallel using channel wires. within writer loop, the write endpoint continuously writes the value of the iteration terminal to the channel. Hi everyone, i have written a program which contains multiple parallel while loops (15 or more) which seem to execute simultaneously. for the moment, the application works works perfectly as all the threads ( loops ) start at the same time bringing own cycle time and lv seems to work in parallel. I have a question concerning running two parallel loops when daq device is involved. i have a few input channels, which are configured for sampling at fixed rate (it can be done before entering the while loops, since it's done for all channels). Is it expected that the while loop only runs when the for loop is done running? yes, it is expected that the inner, nested loop will complete its run before the outer loop runs again. to run them in parallel, the loops cannot be nested and the inner loop must be pulled out of the outer loop.
