Initialize numeric array to a sequence of values

[SumitN]

Is there a way of using TestStand array expressions to achieve the functionality that LabVIEW ramp by delta function has: https://forums.ni.com/t5/LabVIEW/how-to-best-initialize-array-to-sequence-of-values/m-p/3360005/high...

Hi SumitN,

The attached sequence file uses a for loop with an expression to generate a similar vector to the ramp by delta but this begs the question: why wouldn't you just use that function in LabVIEW and output the result back to TestStand?

Hi SumitN,

If you wanted to do this within TestStand, rather than call a LabVIEW VI, it can be easily be implemented through a Statement step:

This can be achieved by configuring the expressions and looping as follows:

I've attached an example sequence with the above step included.

I hope this helps.

Creating a VI just to create a array of sequential values seems an overkill since this seems like a simple task which can be done in TestStand expressions. All I need is an array with an increment/delta of 1. The other option is to call "Ramp pattern by delta.vi" from vi.lib in program files but this will create a headache for me for deployment.

I wasnt able to open your sequence since its in TestStand 2017 whereas I am at 2016.

Thanks this was what I was looking for.

No problem, glad I could help!

@SumitN,

Thanks for the reply and sorry for the version conflict! That definitely makes sense, I just wanted to understand your use case in case there are additional alternatives which weren't being covered. Sounds like a simple looping statement will cover it for you, though. Have a good one!
