• How to send a variable for Labview TestStand?

  Hello

  32-bit Teststand 2014

  32-bit Labview 2015

  Not sure if a matter of Labview and Teststand.

  I created a simple labview VI that has an indicator of success/failure.

  I created a simple teststand when having a success/failure of test with the labview VI as the file.

  I have a labview GUI that runs the teststand sequence and indicates if the sequence whole success or failure as a popup message.

  I have disabled reporting teststand.

  On the labview GUI, how can I show an indicator that my test pass/fail success or failure after the step of the sequence is over?

  If this can be done during the execution of the sequence, then how to display an indicator that my test pass/fail success or failure after the entire sequence ends?

  For example,.

  If I run two digital tests in my sequence. 24VDC testing and other tests of 3.3Vdc. After the execution of my order, I invite myself just at the end if the two tests either success or failure. However, if a test fails I will not be able to know the man who. I want to be able to tell which test failed with an indicator on my labview GUI and not a teststand generate report.

  I'm not sure if it's something to teststand I need installation with local variables or elsewhere in labview. I don't have a whole test report, I want to just the user to see an indicator that a particular functionality test adopted during the teststand sequence.

  Any help would be greatly appreciated.

  Thank you

  
  

• Convert a name cluster Labview Teststand container name

  Hi all

  I realized that day that there is no way to convert a Labview

  cluster in a container of Teststand and vice versa. So I'm currently

  work on a cluster/container recursive parser that would be

  rebuild the structure of mirroring in variant/PropertyObject

  tree. For this I use the following table:

  http://zone.NI.com/reference/en-XX/help/370052N-01/tsref/infotopics/labview_data_types/

  The problam I am now facing is to convert the name of each

  ELEMENT by its name to stay compatible with the

  the structure of mirroring. That's why no space or special characters

  to follow the naming convention Teststand. You can

  See what happens when you create a custom data Teststand

  Type a connector for Labview.

  So, is there a VI that do the trick, or am I still pruposed to do

  Everything by hand? Thanks for your comments. Even the one who

  will not make me happy.

• Entry value change when he went from teststand for labview.

  Hi all

  I try to spend my labview VI value hexadecimal teststand. When I run the VI independently giving the value as 00000010 I get the expected results of the VI.  But even when value is passed through local variable teststand, when it reached VI of entry it was conerted to 000000 A 0 and so I'm getting wrong output.

  I am not able to understand how the value goes to the value of the input parameter when she went from teststand for labview.

  Any ideas?

  I discovered the error.  I was entering the value in the wrong format in teststand... instead of 0 x 10 I've entered only 010 and was therefore is converted to A.

• Implement the Std::Vector < < Point2i > > Std::Vector in dll wrapper for LabVIEW

  Hi, I'm writing a wrapper dll that using OpenCV function. I had been sucessfully implement Std::Vector by referring to "An array of clusters to a dll C sending".

  And now, I want to implement the Std::Vector<>> who is a lot like table 2D but each line items may be different.

  In LabVIEW, I attribute a range of cluster of the dashboard cluster of 2 I32 elements, structure which is shown below:

  

  I think it has the same functionality as Std::Vector<>> in C++.

  So I plug this data on the "Call library function node" structure and generate C code that indicated below:

  /* Call Library source file */
  
  #include "extcode.h"
  
  /* lv_prolog.h and lv_epilog.h set up the correct alignment for LabVIEW data. */
  #include "lv_prolog.h"
  
  /* Typedefs */
  
  typedef struct {
      int32_t elt1;
      int32_t elt2;
      } TD4;
  
  typedef struct {
      int32_t dimSize;
      TD4 elt[1];
      } TD3;
  typedef TD3 **TD3Hdl;
  
  typedef struct {
      TD3Hdl elt1;
      } TD2;
  
  typedef struct {
      int32_t dimSize;
      TD2 elt[1];
      } TD1;
  typedef TD1 **TD1Hdl;
  
  #include "lv_epilog.h"
  
  void funcName(TD1Hdl arg1);
  
  void funcName(TD1Hdl arg1)
  {
  
      /* Insert code here */
  
  }
  

  Then, I write this code show below in dll wrapper:

  void funcName(TD1Hdl Blobs)
  {
      vector < vector > blobs;
  
      // Distribute contents of blobs to Blobs from LabVIEW
      MgErr err = mgNoErr;
      size_t arraySizeInBytes = Offset(TD1, elt1) + sizeof(TD2)*blobs.size();     // Determine row size
      err = DSSetHSzClr(Blobs, arraySizeInBytes);
  
      if (err != mgNoErr)
          return;
  
      (*Blobs)->dimSize = blobs.size();
  
      for (size_t i = 0; i < blobs.size(); i++) {
          arraySizeInBytes = Offset(TD3, elt) + sizeof(TD4)*blobs[i].size();  // Determine col size of each row
          err = DSSetHSzClr((*Blobs)->elt[i].elt1, arraySizeInBytes);
  
          if (err != mgNoErr)
              return;
  
                  /*......................*/
          }
  }
  

  When I call LabVIEW dll, the program get interuption(i.e shutdown) on line where I want to determine the size of each row.

  Could someone give me some suggestions on this subject or promote another application of this requirement?
  Thank you very much.

  MgErr funcName(TD1Hdl Blobs)
  {
      vector < vector > blobs;
  
          Labeling(image_binary, blobs);         // the prototype of this function is: Labeling(Mat &binary, Vector> &blobs)
  
      // Distribute contents of blobs to Blobs from LabVIEW
      MgErr err = mgNoErr;
      size_t arraySizeInBytes = Offset(TD1, elt) + sizeof(TD2)*blobs.size();      // Determine row size
  
          if (contours == NULL)        {                Blobs = (TD1Hdl)DSNewHClr(arraySizeInBytes);                if (Blobs == NULL)                         err = mFullErr;        }        else                err = DSSetHSzClr(Blobs, arraySizeInBytes);
          if (err != mgNoErr)                return err;    for (size_t i = 0; err == mgNoEerr && i < blobs.size(); i++) {
          arraySizeInBytes = Offset(TD3, elt) + sizeof(TD4)*blobs[i].size();  // Determine col size of each row
  
                  if ((*Blobs)->elt[i].elt1 == NULL)                {                        (*Blobs)->elt[i].elt1 = (TD3Hdl)DSNewHClr(arraySizeInBytes);                        if ((*Blobs)->elt[i].elt1 == NULL)                                    err = mFullErr;                }                else               err = DSSetHSzClr((*Blobs)->elt[i].elt1, arraySizeInBytes);
                  if (err == mgNoErr)                {                        (*((*Blobs)->elt[i].elt1))->dimSize = blobs[i].size();
  
                          /*......................*/
  
                  }
          }
          (*Blobs)->dimSize = i;        return err;}
  

  Personaally I've usually done like this. Already, the tar of DSSetHSzClr() indicates if there was something wrong and that the handle cannot really become NULL to call this function.

  To be entirely correct and safety integrated, you must do more than that. But as long as you assume that the incoming picture is always smaller that the outgoing Board will be (usually it be 0 items when you enter this function, but if you reuse sort table in the diagram, by storing it in a registry change for example, this may not be true more) this will be enough.

• What is the best way to open close, then send instrument labview teststand model handles parallel?

  I have a number of test systems that use a parallel model with labview. We have a number of instruments (PXI).

  What is the preferred method to open, close and passing instrument handles with labview teststand?

  Hello

  A few ways

  1 package return the session as a U32 handle, there are a few VI TestStand i of the palette of TestStand that you can use to make conversation.

  2 through a LabVIEWIOControl. TestStand handles these.

  3 do something fance as the use of LVGOOP and leave the handle as an object property and leave in memory. for example, do not pass it back at all.

  One thing, you'll have to monitor multiple executions trying to talk to the same instrument, use some lock/unlock or synchronization to avoid thi.

• 2651 a conversion of TSP Script for LabVIEW

  Hello

  I have a problem on the conversion of all TSP scripts that contain functions and appeal for the end loops. I'm new to the TSP with models of trigger scripts. I used the Script Builder (TSB) Test tool and am able to run any TSP and generate raw data, but I don't seem able to convert most of the codes in the command of LabVIEW VISA or loader LV TSP TSP and run it to generate data... I can't find any tutorial or examples how to do it.

  Let's say that... Use the example of KE2651A_Fast_ADC_Usage.tsp (pulse) and I'll just focus on the portion of function CapturePulseV (pulseWidth, pulseLimit, pulseLevel, numPulses). I have seen a few examples of LV that says loadscript myscript and close on endscript.  I did a lot of different approaches, and I kept getting errors in particular the print function that I am not able to generate data through LV by to read the data in the buffer to inside the instrument. Some approaches, I have had no errors but no data... Some approaches, I got error-285.

  The part of the code TSP pulse that works in TSB is here (I'm not including loadscript and endscript) and what is the RIGHT way to modify the code for LabVIEW and run it and obtain data? Thank you:

      end
  end
  

  I finally solved it myself! I first create support shell, according to the documents, but the problem was with functions of scripts but I solved by introducing VISA separate, feature writing and THEN retrieve the data from the instrument directly by VISA buffer read more. I did TSP_Function Script Loader that allows simply copy/paste codes teaspoon (any * .tsp) of: TSB program or incorporated into this type of function and loader.vi, name (parameters), defined by its own pasted script then it will generate RAW files directly in the array of strings that can be broken into pieces or restructured into what you want as for the graphics, etc..

  That's all I really need to do, I can do codes of tsp in LV and get the data off of it easily via the function defined. Now, this Loader.VI behaves in the same way that TSB keithley-made program I use.

  Here I add Loader.vi Script TSP_Function (in LV 2011 +).

• From the telnet session between calls of LabVIEW, TestStand

  TestStand, I'll call telnet.llb VI.

  In a step TestStand am opening a telnet session to IP address and the collection of the telnet (U32) connection. In the next step of TestStand, I pass the telnet connection to a telnet writing VI, but this error occurs.

  "Dequeue item to acquire Semaphore.vi:1-> Write.vi:1-> Telnet Write.vi.ProxyCaller Telnet"

  The telnet open, write, read and close the excellent work if I get the number of telnet in the same VI session. But I need to keep the session open between TestStand calls because a huge VI is not possible.

  Thank you

  Josh

  Verify that your adapter for LabVIEW has reserved the execution. If it is already, I don't know, you may need to create a parallel thread that keeps the session active.

• Data for LabView - Motorolla RAZR dashboard

  When view LabView, the Android Market data dashboard tells me, 'your device is not compatible with this item."

  I have a Motorola RAZR.  Any suggestions?

  Hello duane,.

  At that time, dashboard of data for LabVIEW is available on shelves.  In addition to the Apple iPad and iPad 2, Android tablets only under 2.3 or later are supported.  To support the Tablet 7 '' Android, we had to make some design changes.  It should be even more changes due to the small size of a phone.  We might consider a version for phones based on the popularity of the application on each platform and the information received in return.  For more information, see the product page or the LabVIEW Web Interface Builder and data dashboard discussion forum.

• Support for LabVIEW 2016

  Can someone tell me what VirtualBench drivers will be available for LabVIEW 2016?

  Release date is... right now! NOR-VirtualBench 16.0, with the help of LabVIEW 2016, is available here:

  • Driver 16.0.0 and NOR-VirtualBench Application

  (My apologies for yesterday, does not but it takes a little while to download pages to go live.)

• Support of NOR-DNET for LabVIEW 2013

  We currently use OR DNET 1.6.6 with LabVIEW 2011. I installed LabVIEW 2013 now also on my computer and tried to synchronize all of the drivers with my installation of LabVIEW 2011.

  Well, it seems that NEITHER-DNET does not support LabVIEW 2013, at least officially. compatibility of Version of LabVIEW and NOR-DNET indicates that NEITHER-DNET 1.6.6 supports 2011 NOR-DNET 1.6.7 2012 LabVIEW and LabVIEW.

  The list NOR system driver November 2013 set OR DNET 1.6.7 defined pilot. When I try to install it, there is no support for LabVIEW 2013.

  My question is, if there is a plan to include support OR DNET for LabVIEW 2013 or later in the game to pilot?

  I copied the directories vi.lib\DeviceNet and vi.lib\nidnet of LabVIEW 2011-2013 and I can load my programs without any problems. I always did not build an executable and does not run on the test set-up, but projects can be loaded in LabVIEW 2013 without any screws of brocken. should I expect any problems running LabVIEW 2013 with the NOR-DNET to 1.6.6 and 1.6.7 driver?

  Nick

  There should not be problems but it is a former pilot, we will not be updated for the future version of labview.

• How to convert the file with VI for LabView .lib to CVI?

  Hello

  I have the .lib file for my lock in the amplifier. The lib file is written for labView and already contains a visual interface (like ActiveX). The point is that I need this file for programming in CVI (8.5). How can I convert a LabView ICB .lib?

  Thank you.

  Denis.

  You said that you had a .lib file and in fact you have an llb file. There is a huge difference between an "i" (eye) and a 'l' (ell).

  There is a LabVIEW Instrument Driver Export Wizard but it's only for new pilots of project lifestyle and you need LabVIEW. There is no other way to convert a LabVIEW driver to a driver of the CVI. If the LabVIEW driver uses methods and properties of the ActiveX, you will need to write the same thing in CVI.

• What type of support for labview usb protocols?

  Hello guys I want to connect a device to your pc via a usb port and I want to use labview to analyze the data.

  But first of all, I would like to know what usb protocols support for labview.

  USB, USB CDC and other TMC?

  I ve read labview recognizes a raw device to the usb, but what is? Is it VI to read and send data, or I have to do? If these VI exists, they do the handshake? flow control?

  Thank you.

  Please read the chips and have a look at the USB specification (it is linked to in the nuggets).

  TMC, CDC, MAss Storage are all built on the basic USB protocols.

  LabVIEW has no built-in support for one of these classes of devices except Test and measurement.
