Hmm. The diagram could (=should) be a lot clearer. Have you tried the
automatic diagram cleaner? Kudo's for the comments though.
Also, you say you reverse the array in the end, but in fact you rotate it
with the number of samples. This doesn't effect the array at all! Instead,
you should use the "reverse array" function.

Producing test software using labview ...

Hi friends,
For those of you who produce test software using LabVIEW,
TestStand, and C/C++, what are your biggest development problems? (By
the way, this can be hardware or software.)
George

Ravens Fan pretty much sums it up. I suppose you can add onto it being forced to deal in a specific platform due to customer requirements when you know it would be orders of magnitude easier with another platform.
Out of curiousity, what is the purpose of the question?

TestStand Full Featured Labview OI - Documentation?

Can anyone point me to any documentation/examples out there for the TestStand Full-Featured Labview OI? I have tried looking just about everywhere and can't seem to find any good documentation/explainers on how the OI works and how to customize it. I am new to TestStand OIs and am trying to create an OI that allows me to run up to 6 different UUTs independently at the same time. I can't figure out how to wire in each individual Execution Entry point and am looking for examples and/or documentation. I also need some help with Progress bars and test status indicator LEDs.

Below is an example front panel of what I am trying to accomplish. Most of the controls are not connected of course :-). I am trying to have one window with 6 different executions shown within it. Each execution would be seperate from one another and you would be able to view each just by clicking on the tab for that particular test fixture. The only thing that would be common is that each execution would be running the same sequence file. The individual test fixtures could be at different points in the test sequence and could have different start and stop times for each. For instance....test fixture #1 could be loaded with a UUT and started into test then while it is running test fixture #5 could be loaded with a UUT and started into test. In the meantime when test fixture #1 has finished testing I could load another UUT into test fixture #1 while test fixture #5 is still running. etc etc

In the Full Featured LabVIEW example, what makes the entry point button reappear?

My question is this: What piece of LV code or invoke node for the TS engine makes the Entry Point button reappear when a sequence file is loaded?
Background:
I've inherited a modified version of the Full Featured LabVIEW UI, which has been moderately modified (Enough so that restarting isn't really an option, but it's still similar enough to use them as comparisons for behaviors). Also, this code was started in LV2012/TS2012, and I'm migrating to LV2013/TS2013, but this behavior was consistent in both versions.
Here's what I've tried:
I found that when the Connect Command executes (See attachment), the button, which is a TSUI.IButton control, is gets greyed out or hidden. In the unmodified example UI that's provided with TestStand, the button reappears when a sequence file is loaded. The problem is that when I load a sequence file in my code, and click on it ahead of running, the button does not reappear. In my code, I can run the sequence successfully by right clicking on the sequence file and selecting Run, so I don't believe the sequence has an error, nor the process model.
Thanks in advance,
Seth

Seth,
The "options" input of the ConnectCommand function controls this. On the Help page for this input, you can see that there are options for "ignore enable" and "ignore visible". Either of these could impact the functionality of the entry point button. You might try making the options for both buttons 0 and see if this resolves the issue. If not, please let us know.

How to get the value of the global variable of test stand in labview User interface?

Hi.
Can anyone Please share examples and tell me to how access the test stand global variable using labview user interface.
Solved!
Go to Solution.

I'm not surprised that what you are doing doesn't work. The Start Execution UI Message is triggered when the user clicks a button to start an execution. Realize that most executions go through a process model. So you could be looking at the sequence context of the process model and not your client sequence file.
I recommend reading that link I posted above. UI Messages are your best bet but you cannot just piggy back on an existing UI Message like this. They may not be getting sent at the time you need them to be. The only way to ensure you get what you want is to trigger one yourself at the right time.

Trying to run Accutest 1000 manufactured by Physical Testing Equipment with Labview

We have an Accutest 1000 which is manufactured by Physical Testing Equipment and we would like to run the equipment and gather data thru Labview.
Does Labview support this type of activity? Is there a 3rd party that would contract to set-up this configuration?
Thanks

National Instruments doesn't officially support interacting with this board. Do you have more information about it? Can it communicate via serial? If so, you could try to use NI-VISA to communicate with the board.

Unit Test Framework Crashing LabVIEW Project

[Cross posted to LAVA]
OS: Windows 7
LabVIEW 2009, LabVIEW 2009 SP1.
Howdy
If I create a project and add a VI and a unit test to it and save it, then delete the unit test, everything works.
If I do the above but put the unit test in a virtual folder then delete it, the project hangs and LabVIEW crashes.
I have tried this on multiple computers and get the same effect.
If it is an issue I thought this may have been fixed in 2009 SP1, but it is not.
I do not remember this happening in 8.6.1 but I was using VISTA at the time (if that is related?)
I get the same problem if I open an existing project with unit tests in it.
Additionally I have noticed that the files from the unit test in Windows 7 have no "logo/icon" associated with them. I thought in VISTA they had the same icon as what is shown in the project - the green plus sign (but this was a while ago).
Is this a known issue / can anyone else confirm this?
Cheers
-JG

Hi Kyle
Thank you for your quick reply.
I am having this problem on my work PC, home PC and a colleague's PC all running Windows 7 and 2009 SP1.
I have found the problem occurs if I create a new unit test OR drag and drop an existing unit test into the project.
Attached is a (jing) video of what is happening every time.
You will see that at the root level of the project (My Computer), I can remove the unit test with no problems at all.
But if it goes into a virtual folder and I try to remove it - then LabVIEW crashes.
The attachment is in LV2009.SP1 and is the sane project as used in the video.
I look forward to your feedback on resolving this issue I am having.
Cheers

Test coverage in LabView Unit Test Framework

Hi,
can somebody from NI confirm the following two statements about the Unit Test Framework:
1. The framework does not support "recursive coverage metrics", where the coverage considers sub-VIs that are executed in the VI under test.
2. 100% coverage means something weaker that common "branch coverage". For example, an "if" VI is a branch in the program but it is not considered as a branch by LabView's test coverage metrics.
Thanks,
Peter

Hello Johannes,
I'm interested in branch coverage of a VI under test.
Imagine a VI A that calls another VI B. If A is tested and LV's unit test framework reports 100% test coverage for A, it is possible that the test cases didn't visit all frames (branches) in B.
Now my question is: is it possible that LV thinks of A as "flattened" so that all code in B is considered as code of A?

Labview 8.2 close or crashes when opening up Test Exec. from labview 5.1

Why would Labview 8.2 close or crashes when opening up Test Exec. from 5.1? Labview 8.2 begins to load the Test Executive VI, then, stops and closes labview altogether. I remember getting it to load before but do not know what could be causing this? I am tasked with updating the old code from Labview 5.1 to Labview 8.2.1; actually Labview 8.5, since it is the latest.
Thanks, Mike

Dennis,
Thanks for the response. The odd thing is that I am able to open some of the subvi's. And I've opened the test executive before. Now, during the initial loading of the Test Executive, there are some drivers that are not executable by Labview 8.2.1 (i.e. ni-daq cards.... for MIO and DIO boards). Could that be it? I would expect the program to load but not run. I have gotten the program to load before, so I am confused by it not loading now. Thanks for the tip on Labview 8.5 as I was ultimately going to that version, too!
My ideal situation would be to load all drivers ( including Traditional Ni-daq and Ni-VXI 3.3.1, etc) and run this program using Labview 8.5 or 8.2.1 on an XP platform. This original program was created in Labview 5.1 and Windows NT. Any help and suggestions would be appreciated.
Thanks for your help,
Michael

Configure Event Callbacks in test stand using labview

Hi,
I was going through Full OI - Configure Event Callbacks.vi in the test stand example. Can you please explain me how the vi works and what is techniwue behind it?
When i open the individual VI's in the reference, I could see more that 1 control in the front panel. But Only the user parameter is wired in the vi? Why is it so?
Regards
Gopal

Hi Gopal,
When the TestStand Engine fires events, this VI specifies how your Operator Interface will respond. For example, let's examine the first event callback registered in Full OI - Configure Event Callbacks.vi , Exit Application. When the TestStand Engine receives the message to shutdown, and then finishes its neccessary shutdown procedures, it will send a message to the Operator Interface. For the Operator Interface to receive this message, it must "listen" for it. In LabVIEW, this is done by Registering an Event Callback. See the links below for details on how to implement this.
The answer to your specific question is in step 7 of the first link below. When TestStand sends the message to LabVIEW, there is information that is always passed. The other input controls contain this information. To create a VI that always includes these controls, right-click on the VI Ref input to the Reg Event Callback Property Node, and then select Create Callback VI.
Here are two references that talk about handling ActiveX callbacks in LabVIEW in general:
Registering and Handling .NET and ActiveX Events
Register Event Callback (Not in Base Package)

How to automate testing of features that require user interaction?

I am currently evaluating a test automation tool (RIATest) for my Flex app. In my app, the user uploads/downloads several files from the server. When I try to create an automation script for the process, I get error #2176 (also copied in the end of the post).
Now, my question is that is there anyway to prevent this from happening? Is there some config file that could be modified to set up an isolated test environment without these security restrictions?
My app uses some features that are only available with Flash 10, so using Flash 9 is not an option (I have understood that these security settings came with Flash 10).
Thanks.
Error: Error #2176: Certain actions,
       such as those that display a pop-up window,
       may only be invoked upon user interaction,
       for example by a mouse click or button press.

Well, if player version is the problem, you can restrict the minimum version required and if the user's version is lower, he will get asked to update.
Thanks for the reply.
I need some features that are only present in FP10, so I need to compile against that version.
Actually, I installed FP9 to my browser and compiled the app against version 9. Everything went well so far, maybe I'm getting confused with my own software already
Anyway, that got me one step forward. When uploading a file, the user is presented the file browse dialog, which in my knowledge is the operating system specified component. At least RIATest doesn't seem to be able to control this. If someone knows how to handle such case with any test automation tool, please let me know.
Edit: Just found this discussion on the same matter on RIATest forum http://www.riatest.com/forums.html?func=view&id=246&catid=9#246
