Create a Custom Multiple Numeric Limit Test

[MarcusTörndahl]

Hi,

I am trying to reuse the "Multiple Numeric Limit Test" calling a LabVIEW VI which outputs an array of a cluster. The cluster contains:

• Name (String)
• LimitMin (DBL)
• LimitMax (DBL)
• Measurement (DBL) 

The "Measurement" should be analysed using the GELE-comparison type and the "LimitMin" and "LimitMax" should be used as the "Low" and "High" limits. My goal is to make the analysis in the same step as the VI-call. Ontop of this I don't know prior to the call how many elements there will be in the array, so there is a need to programmatically control the analysis scope. 

How should you solve this problem? 

Best regards,

Marcus

Why does it have to be in the same step?  Consider the attached example.

Hope this helps,

Hi Jigg,

The reason for having the solution in the same step is that there are a large set of testcases which will be called in the same way. Your solution does solve the problem and by reusing a call to a subsequence the main sequence gets a neet and readable overview.

But is it possible to create a custom step type like the "Multiple Numeric Limit Test" with an array of cluster as an output (as described earlier)? I have searched for a step-by-step in-depth tutorial on creating a "Custom Step Type" but haven't found any which goes into more detail than this (https://www.ni.com/docs/en-US/bundle/teststand/page/creating-custom-step-types.html). Is there anyone who could help me out explaining the progress on creating a Custom Step Type like the Multiple Numeric Limit Test?

Best regards,

Marcus

After some searching (NI.com) I found a step-by-step tutorial (Creating a Waveform Custom Step Type and Adding Information to the ASCII Report) somewhat similar to my quest. I will try to reuse this tutorial and give you the feedback on the progress.

Hi Jigg,

I tried out your attached example and unfortuanetly I only get the limits for the first measurement. My testcase consist of several measurements where each have its own limits. Is there a way to tweak your example to get this? When I added a second "limits" to the tests I got the limits for the first two measurements.

Best regards,

Marcus

What are you seeing?  Attached is what I see.  It looks like they all have limits just fine.
