Numeric limit test
Hi,
I am generating a html report with the requirement as follows:
Need to perform a numeric limit test.
If the value is with in the limits the step status in report should be "Passed" with default back ground color(Greeen).
If the value is out of limits the step status in report should be "Failed" with default back ground color(Red).
If the value is at the limits the step status in report should be "Passed" with back ground color as "Yellow".
I know for this to happen i need to play with the process model. But not sure where to perform this. Can any one tell me where to change in the ReportGen_html.seq. Pl let me know if this can be performed with a custom step type.
regards,
Ramjee
Hi Ramjee,
Isn't this the same query as http://forums.ni.com/ni/board/message?board.id=330&message.id=28990#M28990
Did you look in the relavant sequence and sequence as specified in the above link?

I need to know the differnece between the Numeric Limit Test between the TestStand version 3.0 to 3.1. If there is any differnec in the source code how to find it out? If somebody has the code can you share it?
Thanks,
JeyanHi,
I don't believe there are any differences between the two versions. But you can check the source code for the Numeric Limit Test in TestStand\Components\NI\StepTypes\CommonSubsteps. But the main part of the step is the Code Module and this bit the users supplies this.
What has prompted this question?

The "Edit Numeric Limit Test" help page is wrong
The last four limit types incorrectly say "and" where they should say "or" in the limit comparison. The software gives the correct information in the status line just below the limit type editing screen, only the help file is incorrect.
David@Work -
Thanks a ton for reporting this! I went ahead and documented this for fix in a future version of the software, and I also documented that the Multiple Numeric Limit Test documentation is incorrect, as well.
For your reference, this was reported to R&D #118475 for further investigation and fixing.
Thanks again for your feedback!

Multiple Numeric Limit Test - Evaluate Post and Status Expression
We have a Multiple Numeric Limit Test where the limits for one of the measurements is a function of one of the other measurements.
In the Post-Expression there are two expressions that set the low and high limit based on one of the readings.
But the comparison does not seem to be using the calculated limits.
The report file shows the correct calculated Low and High Limits, and shows the measured reading as being in between the Low and High limit, but fails that measurement. I feel the Status Expression is using the default limits that are out of range.
The post expression looks like this
Step.Result.Measurement[2].Limits.Low=Step.NumericArray[1]*1.9,
Step.Result.Measurement[2].Limits.High=Step.NumericArray[1]*2.1
In Table 3-4 "Order of Action that a Step Performs", Evaluate Post-Expression (Action #15) is before Evaluate Status Expression (Action #16), but it seems that is not the case.
Or am I changing the wrong Low and High Limits. Am I just changing the Limits used in the report file and not the limits used for comparison?
Again the correct low and high limits are in the report but not used for comparison.
ThanksDigging into the NI step type for Multiple Numeric Limit Test, I find that the comparison is done at Post-Step substep which is before my Post Expression is evaluated to set the correct limits.
So I have added code to my VI module to set the limits after taking the measurements but before returning to TestStand. -
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
KimKim,
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? -
Overriding Result Status of a (Multiple) Numeric Limit Test
I want to be able to change the pass/fail status of a numeric limit test from a CVI DLL, whilst still displaying the numeric results in the report. I have tried ResultStatus, StatusExpression and many others but they all seem to do nothing or get replaced by the result of the numeric limit evaluation. Is there a method of supressing the numeric limit evaluation or prefferably performing the individual comparisons but overriding the overall result.
TIA,
DaveYou would have to do the overriding in TestStand. On your Test Step, open the Properties page and go to the Expressions tab. At the bottom you will see the Status Expression box. This is where the limits are compared to the measured value to determine pass/fail. You could modify the code here to have Step.Result.Status be either "passed" or "failed". The actual numeric value measured would not be changed.

Hi all,
I have a problem with decimal point character and database logging.
I've deselected "Use Localized Decimal Point" in Station Options->Localization. Teststand should now use "." as decimal point character (ignore the "'s).
When logging to database this is only true for Multiple numeric limit test results, not for Numeric limit test results.
Numeric limit test results use "," as decimal point character where it should be "."
I can't trust the localization settings on the PC as different endusers might have different settings.
Example:
(STEP_NAME and PROP_RESULT.DATA)
Numeric limit test 1,50127667932332
Multiple numeric limit test result_1 1
Multiple numeric limit test result_2 1
Multiple numeric limit test result_3 10.0304317
I've changed the Limits->Numeric format for each test but this change is only applied to the report, not the database result.
Read the manuals but didn't find anything...
Have I missed something obvious, or is this some kind of bug?
Teststand version is 2010.
Windows versions are XP SP3 and Win7. Same behavior on both OS.When something is logged to the database as a number, the database is probably storing it in a way that is independent of any sort of decimal point localization. When you view the items in the database however it is probably going to show you the number based on the current locale settings. This is likely purely cosmetic, for display purposes.

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!

Dynamically configure multiple numeric limit test measurements
I seek to dynamically (programatically) configure a multiple numeric limit test such that I may set / increase / change the number of measurements in the step during execution. For example, I'd like to setup the step for 5 measurements:
M1, M2, M3, M4, M5 with limits 4<=x<=13.
I'll set the result data to {1,2,3,4,5}.
I can successfully set:
MyMultipleNumLimTestStep.ExpectedNumMeas = 5
MyMultipleNumLimTestStep.NumericArray (Number of elements to 5)
MyMultipleNumLimTestStep.DataSourceArray (Number of elements to 5)
MyMultipleNumLimTestStep.Result.Measurement (Numer of elements to 5)
Following that, I can access the individual measurement property objects (by offset) and set the Name, Limits.Low, Limits.High, etc...
During execution, I can view the step variables to see the values getting set correctly.
BUT, in the report, I only see measurement name, status and the measurement value. NOT the units, limits, comparison type.
Step

Take note, prior to execution, I have no entries defined in the Limits tab of the step settings for this step. If I were to define, say, two steps and run again:
Step
Status
Measurement
Units
Limits
Low Limit
High Limit
Comparison Type

M3

M4

M5

If I define >5 entries, my code will limit the result to 5. Any ideas?
Thanks,
DerekHi jigg.
I also need to configure a multiple numeric limit test programatically. Unfortunately your solution seems not to work (in Teststand 2013). Also with your code I get limits and comparsion entries in the report only for the first measurement. This is the one already existing in the step configuration.

Part 20

Part 2

Part 1

If I add a second measurement in the step, this one is shifted (like expected) and shows the limits and comparsion in the report.

Part 1

What is special with the preconfigured measurements, compared to the programatically created test? Any help is very appreciated.
Thanks

Hi,
I have a mutiple numeric limit test. I want to modify the measurement set in the test based on my needs. How to access the measurement set property of the test.
when I do the export of the property using the property loader utility, the data is in avery difficult format to read.
Can you suggesst some alternative?
Regards
GopalHi Gopal,
Besides using the Property loader step, you could use an expression to access the measurement set. To do this, right-click on the step and go to Properties>>Expressions, and the measurements are under Step>>Result>>Measurement. I hope this helps. Let me know if you have any questions.

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
ChrisChris,
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.

Numeric Limit Test - Several arrays and 1 limit set per array
Hello !
I am quite new to Teststand and I get stuck with an issue of which the solution should not be that intricate ... (I think ...).
I would like to use a "Numeric Limit Test" vi (LabVIEW module). This vi returns 3 arrays and I would like to define 1 "min/max" set for each array.
i.e. :
ARRAY1 => each element compared to min1 & max1
ARRAY2 => each element compared to min2 & max2
ARRAY3 => each element compared to min3 & max3
For 1 array, I found this solution : I write Locals.ARRAY1[RunState.LoopIndex] in "DataSource" and all the elements of the array are compared to the limits I have chosen. Of course, when I add 2 arrays, the same limits are compared to those new arrays but I would like to allocate 1 limits set to 1 array.
Does anyone have an idea of an easy solution ?
My Teststand code and the little vi are here below if it might help.
Thank you in advance !
Solved!

Hi,
I am generating a html report and I have a scenarios as follows:
I want to have a numeric limit test such a way that when the value is within the limits the status of the report should have a status with background color as "Green", if the value is at the limits the color should be "Yellow" and when it fails the test the color should be "Red".
By default TestStand provides me the colors for "Green", and "Red" for "Passed" & "Failed". How to get the color code of "Yellow" in my report for the values read which are at limits.
Pl help me.Hi,
The TestStand Message Popup Step Type dialog is nothing more than a configurable CVI dll that generates a dialog window; therefore, it cannot be modified to use different colors or fonts. However, you can always make a custom step type that displays a dialog with the exact dialog style that you want by modifying the existing step type source or by making a new dialog from scratch.
You can refer http://digital.ni.com/public.nsf/allkb/3C52BF61E257D8FC86256D1D0070FFFD?OpenDocument for the same.
