Custom Step From Multiple Numeric Limit Test | Hiding Limit Tab

Hi All,
I am trying to create a Custom step from Multiple Numeric Limit Test. The custom step by itself poplulates the Limits value from the measurement. So I am planning on hiding the Limits Tab in the step settings. Can someone guide me on how to do this ?
Thanks,
Prasaanthan

Prasaanthan,
if you do not need the Edit Substep at all, you can delete it from the substep list.
Keep in mind that TS gains a lot by using very focused modules. So including a module which does two things (taking measurements, populating limits) might beckfire one day result in "difficult to manage" applications.
hope this helps,

Combine "Pass/Fail" and "Multiple numeric limet" tests

Hi,
how is it possible to combine a pass/fail and a multiple numeric limit test?
I know that you can create your own step types and so I already combined these two steps. But now i can only observe the numeric limits. Regardless of the pass/fail source ("Edit Pass/Fail Source") TestStand only looks at the numeric limits. If they are ok the test is passed. If not, it is failed. It does not matter if "Step.Result.PassFail" is True or False.
What is the problem, or do i make any mistakes?
Thanks for your help
Daniel

Hi,
You will need to include the Step.Result.PassFail in the Status Expression. Probably at the moment you only have the NumericLimitTest Status expression in your combined step type. You will need to changed the Status Expression to match your requirement which will give you an overall Pass Fail for your step type.

Custom Looping Multiple Numeric Limit Test SequenceFilePostStepFailure

Hi
I am using a custom loop on Multiple Numeric Limit Test. The SequenceFilePostStepFailure callback is called each time the loop fails and called again when the step fails.
I want to do something (not relevant for this question) when it is looping and something else when the step fails. How do I know the difference? Is there any flag to look for?
I have tried looking at several variables under RunState but haven’t found the right one. Is there one?
Thanks in Advance
Kim

Kim,
Try Runstate.Caller.Step.Looptype you can compare this to NoLooping. If NoLooping then the step doesn't loop. You can also use Runstate.Caller.Step to get a Step object and then just use the API calls to manipulate it. You can read about it in the TS help. To get the loopindex try: Runstate.Caller.Loopindex.
Both should be ran in the SequenceFilePostStepFailure Callback.

Execution order of Multiple Numeric Limit Test?

What is the execution order of "Multiple Numeric Limit Test" in TestStand 2010?
I am using a custom steptype of Multiple Numeric Limit Test. I want to manipulate the input parameter. How can I do that. I am not interested in making a new steptype. I am writing in Post-Expressions and the data is manipulated as they should but it is not evaluated. I is evaluated before the Post-Expressions executes.
For example I am writing: Step.NumericArray[0]= Step.NumericArray[0]*1000/(2.5-Step.NumericArray[0])
The execution order when looking at the TS manual at page 3-13 is Evaluate Post-Expression before Evaluate Status expression. But it is not what I see. I have also tryed using the more simple Numeric Limit Test and it works as I expect it to according the manual.
Anyone knows about any workaround for that?

Hi Ray
Thanks for your reply
I have tried writing what you are suggesting: Step.Result.Measurement[0].Data= Step.Result.Measurement[0].Data*1000/(2.5-Step.Result.Measurement[0].Data)
Still it evaluates the step before the post-Expression. When I am looking at the variables at runtime the Step.Result.Measurement[0].Data is having the correct value but it seems to evaluate the step before the Post-Expressions.
Any other suggestions?

How can I include multiple limits in the sequence file documentation for custom step type?

Hi,
I have a custom Step Type that contains Measurements property under Results. Its type is Array of NI_LimitMeasurement.
I would like to see the values in the sequence file documentation like NI_MultipleNumericLimitTest type.
Is there any trick to do that?
Thanks,
Andras

Hi Andras,
I have made a slight change to the sequencefile 'docgen_txt.seq'.
In the Sequence 'Step Doc' is a section which handles MultipleNumericLimit step type. There is a precondition check on the step 'Add Multiple Numeric Limits' if the step is of type 'NI_MultipleNumericLimit'. As your step type is based on the MultipleNumeric Limit type, I have just removed this precondition and just relied on the existence of Parameters.Step.Result.Measurement. Equally you could add a new section in this sequence to handle your Custom Step Type which is only called when the precodition match your type name.
Now when you run the DocGen tool it handles your custom step type.
Find attached my modified sequencefile 'docgen_txt.seq'.
Just copy the contents of '..\National Instruments\TestStand 3.5\Components\NI\Tools\DocGen' to the User folder. Then place the attached file in the User\Tools\DocGen overwritting the version that is in that folder.
Then launch TestStand and try it out on your sequence file.
If you are using the html version, then you will have to make the same change into Step Doc sequence of the docgen_html sequence file.
Hope this helps

The custom step type

How can I possibly do the custom step type with MS VB and after that to use this with ActiveX Automation Adapter?
"Only a life lived in the service to others is worth living..." - Albert Einstein

Hi,
The process of generating custom steps is basically the same what every adapter you use. ( See user manual chapter 9)
As an example I've taken the Computer Demo sequence found in the TestStand\Examples\ for VB and created a custom step for the Power On test.
Attached is the an ini file called MyTest.ini. Places this in Teststand\cfg\TypePalettes folder.
Then launch TestStand and you should find the new step in the palette.
(This is for TestStand 2.0.1)
Hope this get you started

Can I exclude measurement (of multiple numeric limit test) from results ?

I'm working on test where instrument returns multiple results at one call.
I use NI MultipleNumericLimitTest -step type (TS 2.0.1).
In some cases I'd like to exclude certain measurement from the results.
I could do this for example by setting Comparison type of selected measurement to "No Comparison", so that this measurement is assumed to PASS always.
Is there any property flag or any other way to exclude measurement from the results completely ?
(So I don't want this measurement to affect on multiple limit test status or to appear in the report)
cheers,
Masi

Hi!
Yes, there is a property that you can set/reset that specifies whether the property appears in the report or not.
1. Right click on your multiple numeric step and select View Contents
2. From the tree view, browse to YourStep->Results->Measurement.
3. Right click Measurement and select properties.
4. Click the Advanced button and look for the PropFlags_IncludeInReport flag and uncheck it.
That's it, now your measurements will not appear in the report. If you want some of the measurements (but not all) to be included in the report, then browse to the specific measurement YourStep->Results->Measurement[i], and check the PropFlags_IncludeInReport flag for that property.
I hope this helps. Let me know if you need more information.

Creating custom edit step (LV) for multiple numeric test

Hello,
i want to write a custom edit step (LabView) for a custom multiple numeric test (TestStand 3.0). It should be the replacement for the editmultinumericmeasurementstep. Have anybody done this before and example code or a solution?
greetings schwede

Hello,
thankyou for your answer. But it doesn`t help. I know how to create a custom step type. But I want to create a custom multiple numeric limit test step type with a custom vi as the editmultinumericmeasurementstep. It is quiet difficulty, because i want to create my own measurements (see the attachment). The name of the test should not be measurement 0 or 1 but LED test color oder LED test intensity.

Property Loader and Multiple Numeric Limit Test

Hi!
I'm trying to export the limits of all numeric limit tests im my sequence.
I've no idea what i'm doing wrong, but i fail with exporting the limits of the multiple numeric limit tests. There are only the limits of the "normal" numeric limit tests in my export.
Could someone please explain me how to export also the limits of the multiple numeric limit test?
(TS 2013)

when defining what to export, it is usually easiest/cleanest if you can explicitly define all multiple numeric step measurements as explicit indixes? For example if your MNL step has 2 measurements defined, you'd want to export 4 additional matches...
Step.Result.Measurement[0].Limits.Low
Step.Result.Measurement[0].Limits.High
Step.Result.Measurement[1].Limits.Low
Step.Result.Measurement[1].Limits.High
...and so on for more indexes....
note how the pattern is different from the regular
Step.Limits.*
by default when you try to export using the '>' buttons for MNL steps, TestStand will usually try to help by generating an incomplete/invalid expression of:
Step.Result.Measurement[?].Limits
which it expects you as the user to fix before proceeding, however the '?' is often overlooked, because it's so small!
some people prefer to simply export the entire Step.Result.Measurement.* to the file because they'd prefer not to define array indexes, but this will log the explicit XML for the container values, which may not be as easy for end users to work with... your mileage may vary. Good luck!

Multiple Multiple Numeric Limit Test

Hello
I have a test that I have written (LabVIEW) that produces 2 arrays of numeric Values. 1 array of Gain data and 1 array of Noise data. I want to apply (different) limits to each array (Same limit for each element within array). How do I do this in TestStand. I have used the multiple numeric limit test for tests returning a single array of data but my test returns 2 arrays.
It would be really in-efficient to split the test up into 2 tests as both Noise and Gain data comes back from the instruments in one sweep.
Any clues ?
Regards
Chris

Chris,
Since your code module returns two arrays and you do not want to call the module twice you could have the LabVIEW multiple numeric limit test step to validate one of the arrays and have a None multiple numeric limit step to validate the second array. You have to send one of the arrays to a local or global variable so you can access it from the None multiple numeric limit step.
You could even execute these steps in a separate sequence and call it using a Sequence Call step if you want to see all the process as a single step.
Another option would be to create your own multiple numeric limit step type in order to support two different arrays as the data source at the same time. This solution requires more work from you. You could take the existing multiple numeric limit step type code as a starting point.
You can fin the code under <TestStand>\Components\NI\StepTypes\CommonSubSteps.
If you plan on modifying the code it is better to make a copy under <TestStand>\Components\User\StepTypes and modify it there.
This will prevent future upgrades from overwriting your changes.
If you have any question let me know.
Hope it Helps.
Antonio Lie.

Multiple Numeric Limit Test Names

How do I get the names of the Measurements of Multiple Numeric Limit from inside the VI that is doing the test.
I wish to edit them to reflect the measurement that I am making.
I can find and change the name of the step, but can't see where the name of the measurements are.
Thanks
Omar

Hello Omar.
Your VI can do this by
(1) Get the number of array elements contained in "Step.Result.Measurement".
(2) Get each array elements property "Name".
The attached VI was saved with LabVIEW 7.1.

NI_LimitMeasurement in multiple numeric limit test results ?

Hi,
I'm setting up a database where I will store my teststand results. I've seen that the default "multiple numeric limit test" stores as first result an entry with type_name = "Array of NI_Measurement[0..n]" (n being the number of values returned by this step).
What's the goal of storing this in the database ? Is it only used to know how many results have been returned by the step ?
Regards,
Alex

Dear SG3,
I've a written a simple TestStand sequence which executes a single "Multiple Numeric Limit Test" returning 2 random values :
The results are stored in my database using the default "MySQL Insert (NI)" schema. When I look for what has been written to the database, there are 2 steps results in the "STEP_RESULT" table. The first one is the MainSequence Callback. The second one is my "Multiple Numeric Limit Test" step.
If I then display the corresponding results of this step that are in the "PROP_RESULT" table, here is what I get :
There are 3 entries in this table. The first one is named "Measurement" from type "Array of NI_LimitMeasurement[0..1]". The two other entries are my generated random numbers.
What is the purpose of the first entry ?
Regards,
Alex

Measurement for multiple numeric limit test

Hello,
I am developing a test software using LabWindows and TestStand. In my application, I have added a no: of multinumeric tests. In Operator Interface, I want to display each measurement in run time, instead of waiting for completion of all the measurements with Multiple numeric limit test. Is there any way to receive in TSOP each runtime measurent taken for multiple numeric limit test without waiting for multinumeric limit test over?
Thanks in advance......
Best Regards,
Vijay

Hi Vijay,
Unfortunately, a Multiple Numeric Limit Test will not allow you to return each measurement inside the step as it executes. If you need this to occur, there are other methods that you could take. You could create a custom step type or use many Numeric Limit Test steps and pass them the indexes in your array.
Another method you might use would be to use an Action step and save the array locally. Then, you could use Statement steps to evaluate each item in the array.
