Calculating Mean & SD in Test Stand Locals Array

Hi,
I have an array of data that I would like to process to extract the statistical info like mean, SD etc. Is there a ready made function available in Test Stand to do this without writing custom expressions?
Thanks

K_seeker,
Unfortunately, TestStand does not have built in expression functions for calculating statistical information. You can see a list of all of the expression functions here: http://zone.ni.com/reference/en-XX/help/370052H-01/tssuppref/infotopics/operators_function_expr/
The easiest way to get the information you want is to pass the array to a code module (LabVIEW VI, CVI .dll, .NET assembly, etc.), do the arithmetic there, and pass the final value back to TestStand.

Passing arrays with Test Stand to DIO 96

Does anyone know the easiest way of sending data arrays from Test Stand to a DIO 96 using a LabView dll? I have a Test Stand sequence where I will need to set bits and read bits from a DIO 96 and am going to make a LabView dll. I guess I will need to pass either arrays to and from each port or numeric data to and from each port to a dll and also figure out how the status of the bits in the DIO 96 will be remembered.
What is the best strategy for dealing with Test Stand and a DIO 96?
Has anyone any ideas or example code?

Hi Steve,
either approach is perfectly valid, and as you say, the activeX approach does remove some of the flexability of where you get the data from, however, what you've really described is two separate things, rather than two separate styles of approach.
ActiveX or direct passing are simply the means of getting data from and to your TestStand data space.
Step types are a convenient way of wrapping up particular layouts and functionalilty into a very easily re-usable TestStand development item. You would still need some sort of code module to put with a step type, so you're not necessarily limiting your developed code to the Teststand environment.
Making links through ActiveX allows you to make a solid definition on configuration type items, and allow for edit substeps. For example, the NumericLimitTest step type has step.limits.high and step.limits.low. Rather than pass those to the edit substep as a dll call (which is perfectly valid), passing the sequence context (which also allows you to run the termination monitor etc) allows for the fixed references to the fixed data layout of the step. Self containment like this works when the data sources are fixed as you get with a step type to use the edit substep, or the pre/post substeps.
Working on a dll call allows more re-use because then you concentrate on the data, rather than where it's come from, however, for large amounts of different sources, the dll prototype can become very complex and difficult to document. You end up having to pass lots of parameters and some of them you might not use.
The question you're ultimately trying to answer is "what does it do to my architecture?"
The holy grail of TestStand architectures is any step type can be used in any sequence in any sequence file with any process model under any operator interface. Now this isn't always practical, but the closer you get to it, the more flexibility your system as a whole contains, and the easier it becomes to add in or change the layout / functionality of the system
With this comes code re-use, but the extra development time it takes to make good re-usable maintainable code isn't re-couped until the 4th or 5th re-use.
If you want in this case your passing of the array to occur from many different places in your sequences, and you're building up lots of sequences to use them, then making a step type, and passing through the most convenient method you decide upon will make the implementation of the sequences easier to do.
If you only need it in a couple of ways, then you can do without the step type, and if it's not many different data sources, then pass by parameter to the dll through the function prototype directly, and use a regular DLL adapter to acheive it.
Mostly my 2-cents worth.

Using a local Array in a Business Rule

Newbie question here...
I am writing a business rule that applies a standard rate to a lot of different lines in a business rule. This rate only varies by year, so from a logical perspective I think of it as a 1 dimensional variable. However the rate is actually stored in my normal Essbase cube (8-dimensions) something like the following:
Dimension Dimension Member
Account: Rate
Dim2: No Dim2 Value (A dimension member called "No dim2 Value")
Dim3: No Dim 3 Value
Dim4: No Dim4 Value
Dim5: No Dim5 Value
Dim6: No Dim6 Value
Dim7: No Dim7 Value
Year: [varies by year]
So right now my formula to calculate things looks something like the following:
"Target Account 1" = "Driver Account 1" * Rate ->
"No Dim2 Value" ->
"No Dim3 Value" ->
"No Dim3 Value" ->
"No Dim5 Value" ->
"No Dim6 Value" ->
"No Dim7 Value"
But I have to do this for several "Target" and "Driver" Accounts in the rule, which means an ugly looking rule. What I would like to do is create a local array at the beginning of my business rule and populate it with the rate:
ARRAY _rate[Year]
and then set the value of the array equal to
Rate -> "No Dim2 Value" -> "No Dim3 Value" -> "No Dim3 Value" ->
"No Dim5 Value" -> "No Dim6 Value" -> "No Dim7 Value"
This will allow me to simplify my formula down to
"Target Account 1" = "Driver Account 1" * _rate
My first question is "can I do this?" I've been able to create an array and use it in the formula, but I can't figure out how to populate the values in the array from my main Essbase cube.
The second question is "does it make sense to do this?" In addition to making the code easier to read, my guess is that populating the array once and just using it within the scope of the rule would be a bit more efficient than referencing that big cross dim expression, but I really don't know.
Any advice anyone has would be appreciated.
Thanks
-Glenn

I am familiar with what you are trying to accomplish.
Having Essbase store a fixed rate over time to be used in calculations is possible. However formulas start to look complex depending on how many dimensions you have and what the desired outcome is.
There are alternate techniques to the one you mentioned.
You can create a new database for rates only and make it with fewer dimensions. Then use the @XREF function to retrieve it in your formulas.
If the rate doesn't change very often you can put the Rate inside of the formula as is.
For example Y2006_Rate = 5%.

Test Stand Shut Down with no reason

Hello ,
I'm using Test Stand 4.2 & LabWindows CVI 9.0 .
I'v created a program that checks 30 cards in Batch mode , using Test Stand as master that calls CVI functions from dll files i'v created .
In the program there are no error nor warnings But i have a strange problem for every 50 runs of the program I'm facing 1 Complete shut down of TS with no reason or warning .
TS simply shut down and not showing any message . This problem is very disturbing considering that full check for 30 cards using TS is Approximately 3.5 hours .
The shut down can occur at any part of the run with no repeated pattern , It can happen after 3 min or after 3 hours And by doing so the user need to restart the entire test from the start because TS
didn't produced any Report .
I'm not denying that the crash can be in the dll files written in CVI but thats in low possibility .
I'm under Win Xp and using intel core2duo L7400 and 4 MB of RAM .
Is there any option to avoid this problem ??
Thank You , Kobi .

Thank u Doug i will check it , for now i have pasted the at the bottom the event viewer application log maybe some as i suspected the problem is in the CVI DLL but i don't know what this Error means
Maybe You know ?

Integrate Vision Builder 2009 (VBAI), into Test Stand 4.2.1?

Does anyone know of an easy way to integrate Vision Builder 2009 (VBAI), into Test Stand 4.2.1?
earlier versions of Vision Builder seem to accomidate this very easily. But i have not found the same ease to make this work in the newest version. any ideas?
Thanks

Hi,
Thanks a lot for your support.
Well...yes I followed the instructions in the ReadMe.html file.
I have loaded the sequence "Vision Builder AI TestStand Examples.seq" into TestStand.
TestStand crashes after some delay when trying to select the first test step "Run Inspection once".
TestStand obviously has problems loading the Vision Builder API functions and the engine (whatever is necessary).
As I could not succeed testing VBAI 2010 from TestStand, I then tried the LabVIEW example which is also located
in the \examples folder.
I had no problems loading the "LabVIEW API Examples (Local).vi" into LabVIEW 2010 and execute it.
This example works without any problems with a simple USB Webcam.
I can test different "Inspections" and studied the API functions in this VI.
So the problem is only related to TestStand.
I am wondering whether TestStand has problems with the evaluation version of VBAI 2010.
When executing the LabVIEW example the VBAI engine asks me first if I want to evaluate the software (as it is not activated yet).
I never reach this point from TestStand. It crashes before.
Another point is that I am asking myself why the test step "Run Inspection Once" is the first test step the TestStand sequence.
Comparing the sequence of steps with the LabVIEW VI, you can see that there is a differnce in the initialisation sequence.
The LabVIEW VI launches "VBAI Interface - Launch VBAI Engine.vi" first before all other API VIs.
I could try to change the TestStand sequence and introduce additional initialisation steps before "Run Inspection Once".
I simply fear that TestStand crahses again before I have been able to change the sequence.
Ok...another thought...on your system it is working fine using the example TestStand sequence?
This means that the initialisation of the VBAI engine is automatically executed.
Which process is responsible to initialise the VBAI engine in TestStand?
Perhaps I have to configure something ...somewhere in TestStand.
Ok... that's it for now... i will try out a couple of things....
Thanks again for your support
Best regards,
Carsten

Test Stand 3.5 install problem

I'm having problems installing Test Stand 3.5 Development Edition on a WinXP SP1 machine - would anyone have any suggestions.
I'm performing a custom install and selecting all components other than "Device Drivers".
The install fails on "NI TestStand 3.5 Support Files. Part 1 of 1" with "Error 1335. The cabinet file 'Cabs.m6' required for this installation is corrupt and cannot be used. This could indicate a network error, an error reading from the CD-ROM, or a problem with this package".
If I select abort at this point the install of the support files is rolled back and the remaining components apper to install correctly. I can now run Test Stand but am missing the help files. If I rerun setup it attempts to install the support files but fails with the same error.
I have tried uninstalling and reinstalling & have copied the CD contents to the local hard disk (without any problems) and installing from there. All this is to no avail.
I've also uninstalled and reinstalled an installation on a second machine using the same install media. This install succedded with no issues.

What is the difference between the two machines - where you've had successful and unsuccessful installs?
Like you've said sometimes this is caused by a faulty read from the CD drive, or faulty media, but as you've managed the install with the same media on the machine - then its not the media, and you've already tried the copy to hard disk from the CD without any luck.
What OS is on this other (working) machine?
Do you have administrator privileges on the machine where you can't install the software? Is the .NET framework 1.1 installed (I think this is part of Windows XP SP 2) so this could be the issue - as TestStand requires the .NET framework 1.1
Also - I've attached the readme which includes information to consider before installation - and known issues with the installation - check this and see if any of these could be the issue with this machine.
I hope this helps

Is there any way I can convert a Test stand sequence and corresponding vi's to an executable?

I need some creative ideas on how I can convert a test stand sequence into an executable in the shortest possible time. I know that beats the entire purpose of using TestStand but I need to have a way to do this. Is there no other way i can accomplish this without writing a sequencer in LabVIEW and rewriting all of my code in LabVIEW??

There is no way i know or can think of to move all components from a TestStand application into a single EXE. Running TS in an application means that you should/must work highly unitized during developement and deployment.
In general:
-> Custom UI will become "The EXE" for the enduser. This involves the link for startup on desktop/start menu.
-> TS Engine, ActiveX Server, will be attached to the UI.EXE OS process when launched by the UI. Will never be part of the UI.EXE.
-> TS Compontens (e.g. process model, language files, ..). Will never be part of the UI.EXE.
-> Custom Components (e.g. modified process model components, reporting, ...). Very unlikely(never) to become part of the UI.EXE.
-> Custom Sequences. Will never be part of the UI.EXE, but extension can be changed to other than .seq.
-> Code modules called by custom sequences. Unlikely (but possible) to be part of the UI.EXE. Should be implemented and tested to run within the RTE (runtime engine) of the appropriate programming language. It is not par design, that the deployment system has the development environment of that programming language installed.
-> License information. TS requires at least the Base Deployment License installed and activated (requires NI License Manager software). RTE of modules might also include licensing and possibly activation fees.
Why is there the requirement to have a single, monolythic EXE (hard to handle!) at all? If it is about the deployment process, you know that you can provide a single MSI (Microsoft Installer) with all required components using the TestStand Deployment Utility?
hope this helps,

How can I get Test Stand to print failues only?

Rather than getting a large report file with hundreds of passes and only one failure, how do I configure Test Stand to only print the failures to the report?

Hi,
the engine callbacks are simply a sequence that gets called when a particular thing happens (i.e. Post Step).
There's three types
SequenceFile (for steps that execute in that sequence file whether it's a client sequence file or a process model)
ProcessModel (for steps that execute in the client sequence file run under this process model, but NOT the steps in the ProcessModel)
Station (for all steps on that installation - found in the StationCallbacks.seq sequencefile)
If the engine callback appears in more than one of the three places, then the lowest one (seq file->proc model->station listed lowest to highest)is used.
In your case, you could use any of them depending on your architecture.
Personally, r
emoving from the resultlist is easier than working out whether to add to it, but that gets tricky when you have steps which loop.
If you decide to make up your own add, then the PostStepFailure is the callback sequence to use (go to edit->sequencefilecallbacks). You'll have to add a new element to the resultlist, and start fleshing it out with the result container of the step (which you still have access to as a parameter) plus the TS container.
This would go into the Runstate.Caller.Locals.ResultList[x]
Also, don't forget to disable the result collection on all the steps in the test sequence, plus all the ones in your poststepfailure callback, since you're doing your own.
I'm attaching what I've done so far as an example - not quite finished, but it's done the TS container. Just now need to do the actual result container.
I'll keep working on it but for now you can see what I'm getting at.
Hope that gives you a kick start with the callbacks bit

Batch Sequence Shutdown Test Stand Randomly

Hi ,
I have a problem with Test Stand in one of my projects .
I'm using TS 4 & CVI 9.1 . TS is using CVI DLL .
The software is using parallel Device checking for 30 cards , at 25c , 75c and -15c ( temp ).
While checking 9-10 evrey thing works fine and well buy in 11 and so on TS crashes randomlly about 1 of 10 times at the crash the is no TS message only Windows not responding message .
My main idea was a Resource leaking at the CVI code but i checked it very carefully in addition i cant see the resource trekking in dll mode .
Is there any tool , even windows tool or some software i can use to track my memory while working with both programs !? or you have another idea ?
Thank you .

There are two possibilities for updating a local in one sequence from a subsequence which that sequence calls.
1) Pass the variable as a "By Reference" parameter to the subsequence. Then in the subsequence access it with the lookupstring Parameters.MyParameter. To add a parameter to a sequence, simply insert a variable under the Parameters group. Parameters are passed by reference by default (which is what you want). They can also be passed by value (i.e. a copy to which changes don't affect the original) by changing the setting by right-clicking on the variable and unchecking the by reference setting. Using parameters like this is very flexible and future proof. You can even call the same subsequence from multiple sequences and the subsequence doesn't have to worry about who's calling it. Also it doesn't matter what the name or location of the variable is in the caller, the subsequence just always accesses the variable as its parameter. When you specify the sequence call to call the subsequence you specify what to pass for the parameter.
1a) A variation of this which can help make your code easier to extend is to use a Custom Data Type as the type for your parameter. Make a Custom Data Type that's a container than contains the variables you want to pass. When you need to add a new parameter in the future you can just add it to your Custom Data Type and then you don't have to update any of the places where your subsequences are called to pass the new value. If you go this route I recommend storing the Custom Data Type in a type palette file and keeping it always backwards compatible as much as possible (only add variables, don't remove or change existing variables).
2) Another way which is less flexible is that you can use RunState.Caller.Locals.foo to access a local variable in the sequence which is calling the current sequence. This creates an interdependency between the two sequences though which can lead to code maintenance problems because someone could change the calling sequence's variables, not realizing a subsequence depended on the variables they are changing.
Hope this helps,
-Doug

Good NI Test Stand Examples For a Beginner (Using LabVIEW)

Hi everyone, I am new to using NI Test Stand. I have gone through the "Getting Started with NI Test Stand" and "Using LabVIEW with Test Stand" documents.
I know in the NI Test Stand Example folder there are many examples. Are there any examples that cater to new users to Test Stand?
Where can I find good examples (demos) for developing test sequences, local variables, parameters, etc...in Test Stand?
Thanks so much!

If you have the SSP you could access online training an do the exercises on the training.
but the examples is a good way to getting started. just play around with all the options you have.

Test Stand: TestStand Engine Process

I'm looking into an application (written by someone else of course) which calls a "Test Stand Engine" to execute a test.
First thing is what is this "Test Stand Engine" ?
I have been using Test Stand GUI (Test Stand Sequence Editor) to execute such test cases in the past so I never knew what do they mean by Test Stand Engine.
The problem i'm looking into is simple.
They say that Test Stand Engine is being executed as part of a thread and my task is to make it execute in a process.
But I Can't find the actual call to test stand engine itself.
I'm on Windows box and all I can see in Task Manager => Process is TSAUTO~1.EXE which is same whether I run GUI or my application with Test Stand Engine.
What should I look for in my application code to find the "Test Stand Engine"?
Any Help?
Nirvana

Hi,
just to clarify that - there's two approaches to making an operator interface with TestStand.
1) Use the TestStand UI controls and manager controls or 2) Go directly to the TestStand Engine.
Option 1 actually overwraps the calls to the TestStand Engine anyway to make it easier to implement an operator interface. That's not to say that going directly to the TestStand Engine ActiveX automation server is difficult, but you have to do certain things, like shutting down in a sepcific way.
Your best other resource is the TestStand help (rather than the bookshelf pdf's) and have a look at the topic about "Writing an application with the teststand engine"
As Dennis says - you might get more help on the TestStand forums rather than the LabVIEW ones though.
Thanks

Is there a way to create a database with Test Stand?

Anyone know of a way to have Test Stand create a database? My company standard MS Office suite is Microsoft Access 2010, and TestStand does not support the .accmdb extension type(format), so I have to create new databases using old formats. I'm worried about backwards compatability down the road since good ole Microsoft doesn't seem to care about legacy formats.
I'm still a beginner with databasing, so any suggestions would be greatly appreciated.

TestStand 2012 SP1, and we are using a modified Generic Recordset (NI). The problem we are having right now is that the Build SQL instructions are not creating the database tables the way we are configuring them from the "Statements" and "Column/Parameters" tabs under Database Options.
What is happening is when we validate the schema, and drop all schema tables, it empties all the database tables, but then when you build using the TestStand generated sql file, we get errors(shown below) we are not understanding, and we can no longer write to the database and LabVIEW throws a "Data type mismatch in criteria expression" error like this
"Possible reason(s):

How to bring a VI front panel to the front (of all open windows) when the parent VI calls a sub-VI in Test Stand.

In Test Stand when I call a sub-VI front panel, the pop-up window goes behind all the windows and the user just waits for the screen. I want the pop-up to come to the front so that the user can know what to do. I couldn't find any property that I can set which would make the called VI go to the front.

What version of TestStand are you using? Here are the TestStand palettes in LabVIEW for TestStand 2.0 and 3.1. You can also set a VI to be modal in VI Properties>Window Appearance. Select Dialog or go to Cutomize and change the Window Behavior.

I want to write a program in LabView then pass the test results to teststand to check if it pass or fail without displaying the test stand program,

I want to write a program in LabView and create an execute but I want to be able to pass test results to test stand to find it the unit pass ar fail the test then save the data to a database. How would i go about it.

What's confusing is your statement that you want to do this "without display the test stand program". You can minimize the TestStand UI to the task bar but if you don't want TestStand to be running, how can TestStand evaluate the result. Explain a little more please.
In the message body of your post, you just say you want to create a LabVIEW exe and pass the results to TestStand. What I would recomend is that instead of an exe, you create a dll and use TestStand's DLL adapter to call it and return the results. TestStand will evaluate it and do the logging.

Is there a max number of parameters that can be passed to a C function in test stand v. 1.0.1

I have had an issue with test stand version 1.0.1 (yes, I know; it's quite old) and calling a C function thru an action step. when I call this function with 18 parameters, it seems to hang. I have called a function with 16 and it seems to work. Is this a limit of the software? I am calling the function from a windows DLL that we've created. When I try to pull the function from the dll into test stand I also get a { error...but I get that in the other function's call and it seems to work fine. Any ideas?

ok, upon re-reading what I posted I can clearly see your confusion. haha. I think there are two separate issues.
1) Are there a maximum number of parameters one can use when calling a C function from a DLL? Yes, i'm trying to call a C function from test stand.
2) when I select the "module" tab, and select which DLL contains my function, the prototype has no information associated with it (by clicking the reload prototype button). I'm not sure why, as I'm using a declspec to send the function information out of the dll, but that's another topic. So I click on the source file tab and point the window to the .cpp of my function (within the DLL's project workspace) and when it begins to parse the file, I get an error about mis-matched curly brackets and if I wish to continue, and skip the rest of the parsing.
I click "OK" and when I go back to the module tab, I am able to see all my functions, along with the parameters in the drop down menu below. I fill in all the parameters and everything looks ok; no syntax errors, or anything else seemingly suspicious. I then run my test stand code and when I get to the step which calls this function, the system hangs and cannot proceed.
Any thoughts as to what might cause these issues?
