Execution of LabView

[hellolv]

Hi All,

Does LabView execute multiple loops at the same time or only one at a time?

You can easily have multiple loops running at the same time.  LabVIEW takes care of the threading for you, so each VI may be running a large number of parallel threads at the same time.

Take a look at the producer consumer templates to see a good usage of parallel loops.

Thanks.  In a flat sequence in Loop A, if I change the case of a case structure in Loop B, will the case in Loop B be executed right away?

Or it has to wait til the sequence is over.

Its really hard to say without seeing your code.  Go ahead and attach it so we can all help you easier.

I agree with Evan that without the code this will be hard to answer, but as a guess - If the loops are connected with a wire, then loop B will have to wait until loop A finishes running completely.

To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here, here, here, here and here are a few you can start with and here are some tutorial videos. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).
