Running different sequences in parallel from LabVIEW

[1984]

Hi,

We have a test setup with up to 8 UUT. The UUTs can be different and may require to run different sequences(*) in parallel. Is it possible to start TestStand from labview and run the different sequences at the same time? Sequences potentially run for days, so stability is a requirement. If so, is there an example I can find somewhere to run at least two sequences in parallel?

*The sequences never share the same resources, so they wont interfere with each other.

*All sequences 

*The UUTs are quite similar so theoretically we can create one sequence with a decision making logic, so it can serve all the UUTs. In pratice we cant, because the sequences will be written by our customer and we can't expect them to write their sequences with this mindset. Also the number of potential sequences is huge, so the question is really, if we can run them in parallel.

Thanks!

1. Choose the batch process model.
2. In the implementation, in the main sequence, use a sequence call step.
3. Define the array of sequence paths for each UUT in a FileGlobal variable as an array.
4. In the expression for the sequence call step, format it so that it uses the socket number to index the path in the array.
5. Now, each socket is executing a different sequence wrapped by the same main sequence.

Thanks for responding. I worked with the batch model couple years ago. What I'm looking for now is to see if I can somehow start separate teststand processes. The reason for this is that we'd like to use TS only as a "simple" sequencer, other than this we dont need all those complex functionalities the process models can provide. And not just we dont need those, but I'd like to avoid them as much as possible to reduce the complexity.

That's interesting!

I keep hearing discussions that TestStand is so expensive even though it brings so much functionality.

So my interpretation is that in your case, the benefit of using it as Sequence only already outweighs the cost 😊

I wouldn't necessarily jump into conclusions like this.

That's why I was asking 😉
