TestStand and LabVIEW treat differently polymorphics with instances with bodies of private classes.

I have a class of LabVIEW and the class contains a method that is a polymorphic VI, and that polymorphic instances has. If I put the scope of Private, and the polymorphic bodies access to the public, then I can force developers who use the class to use the polymorphic VI (and not to call directly the instances). It's great. I like that.

but...

I have build a TestStand API that uses a polymorphic and instances as described above. I create a time of LabVIEW, with a type of call class member, and I target my class. TestStand does not support polymorphic VIs, meaning that polymorphs or its instances appear in the name of the Member list.

This means that, to support my LabVIEW users and my TestStand users, I need to create two separate APIs, which is not a place of happiness to be. No matter who encounter this and found a solution? Or I'm looking at this wrong?

It dawned on me later that we could actually change TS to be a static link to a particular instance VI via the polyVI. After all, you can manually select an instance specific polyVI. It would be just a way to declare in TS "link to this particular instance of the polyVI." Allowing the TS to say "I'm going through a public interface to join a private function."

So instead of linking "A.i" you could bind to ' PolyVI.vi: A.i ".

  • Parameter passing between TestStand and Labview

    Hello world

    I'm trying to pass a value of LabVIEW 8.5 to 4.0 TestStand.  After reading some of the posts, it seems that I must have terminals coming from the icon and that these can be edited in the "connection" pane

    I spent a long period of time to search for the "connection" pane and is an instance of unedittable in the class browser.  I have attached my simple VI below.  I want him to give me the ability to change the value of output in TestStand string when I load the module.

    Anyone know how I can place on my VI terminals?

    TIA

  • Variable between TestStand and Labview

    Hi all

    I'm looking to get a tutorial giving an example of use of TestStand Toolbox in Labview to communicate with TestStand.

    I'm just new to that sort of programming and even after having made the tutorial OR "in aid of TestStand.pdf', I don't how can exchange data.

    Thank you

    Vincent

    Hello

    In the pane adapter module, you must file a local TestSTand variable (or expression) in the colum value. Uncheck the box to check by default and remove attributes and it should work perfectly.

    Kind regards

  • Compatibility of boards of daughter BasicTx and BasicRx with USRP2920 and LabView

    I want to know that girls BasicTx and Rx cards Ettus research base are compatible with USRP2920 and Labview or not.

    These cards also supports variable gain or not? Please confirm

    Thank you

    JK

    They will work, but you must use property nodes to configure them. No is no LO so ther is no center frequency setting. I and Q are separate channels so you must separate them and treat them as such. There are no gain as the boards primarily provide access to the ADC.

    While it is for 2011, I doubt that they decided to remove 64-bit compatibility as they went forward as 64-bit has become more rather than less demand.  In this document,notes LabVIEW Simulation Interface Toolkit does not support 64 bit versions of MATLAB application software."

    The extent of the compatiblitly for 32 - bit, I'd take a peek at: http://digital.ni.com/public.nsf/allkb/D174674A91E5536286257428005C2426

    The OP's question was SIT support 64 - bit version of LabVIEW and 64-bit version of the MATLAB/Simulink itself, not the operating system software.

    Document in your second link is on a completely different topic to have API for LabVIEW and MATLAB/Simulink/RTW (well, mostly Simulink & RTW). Here is the relevant link for the 32-bit compatibility: http://digital.ni.com/public.nsf/allkb/049295038FF0EE2A86257A06006B2DAD is no SIT 64-bit.

    Other underlying issues is that Pharlap does not have a 64-bit version. Finally, simulations are better performed on some RTOS (embedded PXI) for a deterministic execution rather than PC operating systems.

  • a problem with one of the files in the TestStand\AdapterSupport\LabVIEW directory

    When looking at the module a LabVIEW VI called for TestStand, I get the following message:

    A problem with one of the files in the TestStand\AdapterSupport\LabVIEW directory.  Please reinstall or repair.

    I made the mistake of cleaning C: in my computer.  Clean the C:\National Instruments downloads

    Why would someone put bits of applications or modules, etc. in such a directory?

    I'm not too crazy about restoring 11FR in this folder.  It's just crazy!

    If anyone has encountered this before?  No "easy"? outside re - install TS...

    Side note: I do not touch anything in the \Program files. National Instruments\TestStand\AdapterSupport\LabVIEW

    What version of LabVIEW and TestStand do you use?

    In 2012, TestStand, this directory is mapped to:

    C:\Documents and Settings\All Users\Documents\National Instruments\TestStand 2012\AdapterSupport\LabVIEW

    Have you tried mass compiling the screws in this folder?

    I had to create a new 'TestStand - default values XX.llb"file, where XX is the last version of LabVIEW you use, but I have not seen this message before.

    Good luck

  • How to open and close an electronic shutter with LabView 8.5.1 using an NI USB-6009 case?

    Also, I need to set up a timer so that the shutter is open for 15 minutes and closed for 30 minutes.  It has to do 500 times.

    The USB-6009 case is a relatively new device, and LabVIEW 8.5.1 is a fairly old software. You should check to be sure that you have the corresponding to your version of LabVIEW (DAQmx) drivers that support of this material. It sounds as if you put it in place to MAX and control the output manually, which is a good sign. I don't have access to the version 8.5.1 and I do not exactly remember which functions he supported, but the attached picture shows a simple diagram in a new version of LabVIEW that would do what you want. Of course, you should test with shorter and less iterations because it takes more than 2 weeks to complete! Add any controls, indicators and the error checking you want.

  • How to get the string (specified by row and column) of txt file with labview

    Hello world

    How to get the string (specified by row and column) of txt file with labview

    THX

    As far as I know, a text file has no column.  Be more specific.  Do you mean something like the 5th word on line 4, where the words are separated by a space, and lines are separated by a newline character?  You can read from the spreadsheet String function and set the delimiter to a space.  This will produce a 2D channels table.  Then use the table to index and give the line number and column number.

  • I have a problem with the simulation in Matlab 6.5 and LabVIEW for PID controllers

    I have a problem with the simulation in Matlab 6.5 and LabVIEW. I have a few methods for granting regulators PID in MATLAB to go but not of LabVIEW. Degree of international teams of two transfer but when I passed to the fourth degree is no longer working. We have changed the formula to calculate the parameters for the fourth year and gave me some good values for assignment of Matlab, but when I put on LabVIEW are not resolved. the formulas are available in PDF format and are. Please help me and me someone if possible. Thank you
    Lim.4 generation in comparison methods and the MATLAB program settings are for the service of transfer to the second degree.

    Hello Lascarica,

    I noticed that you are using the screw of PID. Gains on these screws are based on TIME instead of GAIN. You should be able to build a PID regulator and vary the gains and then compare the results.

  • ButtonField who works for normal click and also occurs a different action with a key down and click on

    I have a bunch of buttons on my main screen. They currently do something when you click on it. I want to make them do something different when ALT-clicked. I built them as:

    ButtonField mycoolbuttonname = new ButtonField("Awesome",ButtonField.CONSUME_CLICK);
    

    Then I assigns each a ChangeListener which then redirects this specific to a specific code listener.

    How can I run an ALT + click on a different code of FieldChangeListener?

    I think somehow with: KeyDown API

    I have several buttons on a screen. All work now with: 1. click on Trackpad 2. Touch-click 3. Enter-click

    I want each button to be able to do two things:

    1. a thing with an ALT-activate(by any of the three ways as seen above)

    2. a normal else activate (by one of three ways as seen above)

    Dominant Navigation click would not however to ALT-Enter and Alt-Touch(The way I want it is that these two do #1 from above too). Correct or not?

    In the simplest possible terms:

    Each button will make a specific thing turn on and another thing different specific on ALT-putting into service.

    Right now, they work absolutely fine to do a thing. But I'll try to find a way to make them also to do something else on ALT-putting into service.

    I think if I can somehow make a way to get the true/false if ALT is pressed during a change of field and then do an if/then based on this information in each fieldChanged method so I should be good.

    Update: well, I got the errors go away with your code above. At least press Alt-Trackpad works. I'm going with it. Thank you!

    Im trying to open the tutorial of 23 minutes on how to use different tools in photoshop and it continues to come with unable to resolve the DNS servers worked fine yesterday? Ive had creative cloud on my laptop for a week and not yet able to get past the basics make me very frustrated.

    I guess you meant the links when you open photoshop CC. I tested all four videos of the 23 min tutorial and they all played fine. If something between you and adobe does not work correctly.

    • Check that your firewall is blocking the net. Try to access youtube videos and see if they play very well
    • Go to the adobe tv site and try to play one of the videos here. Adobe TV
    • If youtube plays very well and adobe tv does not work, next is to check if you have flash installed. Some videos require flash, others are html 5. Sorry that I could not confirm what player has been used for this tutorial. I think that html 5 but not sure.
    • Next is to look at the properties of your browser and check multimedia settings are not disabled if it y in a. (this is totally dependent on the browser)

    Thank you guys!

    Please use SQL for SQL command Append KM... You can delete the unnecessary steps in the KM.E.g. fi you won't create I$ table, control flow etc, then you can remove related steps.

    Please try with that.
