• 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

• Pass parameter value between c# and TestStand

  Hello

  I'm currently futured, customize the User Interface complete

  I Test.seq master who has all the tests and I need to run only the selected test user in the user interface.

  so I thought to transmit the selected user code c# UserInterface test form to master Test.seq.

  How can I pass the value of the parameter or is there another way I can share data between USerINterce and seq file?

  Thanks in advance

• How can I pass data between DIAdem and LabVIEW?

  Hello community,

  in fact I use a LabVIEW application to control a test system, collect data and store it in a file.

  DIAdem is executed (using ITOCommand) and then create a report (PDF).

  This works already.

  But also, I would like to receive a return value of tiara, a real number, as for example the register R1.

  No idea how can be achieved?

  Thank you!

  Declare records, variables in the script of tiara that store the calculated result. Read records in labview

• 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 ".

  Hello Dominique and everyone!

  I have exactly the same problem as the creator of this thread: audio only plays the default device and my system does not switch whenever I say - / my headset.

  I had this problem before, but fixed it somehow. He appeared once again, recently, I think that after installing the latest nVidia drivers, where I forgot to uncheck installing the audio drivers.

  (Steps of Pranav one) through e) unfortunately did not turn.

  Here's a description of my system:

  • I use the Realtek card my motherboard ASRock Z87 Extreme4 Board
  • I use the speakers built-in monitor, connected on the rear plug of the PC with a 3.5 mm jack plug
  • The monitor is connected via Displayport
  • I connect my helmet on the front panel, also with a 3.5 mm jack plug

  Realtek HD Audio Manager detects connections:

  

  Currently, the headphones play audio, since they are selected as audio device by default:

  

  Now, when I disconnect the headset, I want my monitor to continue playback automatically.

  And when I plug the headphones in, I want to play again. I know that it is possible to configure the system like that, since I already had on before. I don't know how to go back again!

  Can someone help me with this? Would be really great, because I'm crazy about this since I'm regularly pass the monitor with headphones. :)

  Here are some more screenshots to illustrate:

  Here the tab advanced discussed:

  

  Completion, the recording devices, since some other forums suggest to change the settings, but nothing helped for me:

  

  And, as an option in the Realtek HD Audio Manager software. Unfortunately, this change also did not help, I think:

  

  Oh, and I just noticed that the display device is actually connected via"digital HDMI" via the Displayport cable, I guess that:

  

  Really don't know what to do with all this... Help, please! :)

  Any help is greatly appreciated and even if you do not answer, thank you for your interest!

• Best way to pass an array between TestStand, CVI

  Hello

  I was not able to judge or to find the best practice to pass arrays between TestStand and CVI. I'd preferably done in pass pointer to array. For example, if I have a function written in CVI DLLs:

  int GetAverage (double* aBuffer, double aSize, double* aAverage)
  

  TS I have an aBuffer double array [100]:

  -I can't simply pass

  GetAverage (aBuffer, 100, &aAverage)
  

  - or, I can go:

  GetAverage (&aBuffer[0], 100, &aAverage)
  

  -The only thing that is TestStand accepts:

  GetAverage (aBuffer[100], 100, &aAverage)
  

  I don't think not good because the size is just repeated.

  I had no problem if I could write

  GetAverage (aBuffer[100], &aAverage)
  

  but the problem is in this case there is no possibility fo CVI to determine the size of the table, like sizeof (aBuffer) just return, sizeof (double).

  Can you provide me with advice for best programming practices in this case?

  Concerning

  RB

  Hello

  Just in addition:

  Is there another way to access the tables.

  Often, I use for this task, the TS-API. The only parameter you need is in this context of the sequence.

  Maybe you should also visit this example:

• Connect the large number of parameters and variables between Verstand and model of Labview

  We have an installer of dyno with a chassis PXI-E running Veristand 2014 and 2014, inertia. In order to strengthen the capabilities and timing of the Veristand, I would use models of Labview to perform tasks is not possible by Veristand and inertia. An example of this is to determine the maximum amount of a large number of thermocouples. VeriStand has a comparison function, but it compares two values at once. This makes long and rigid emissions. LabVIEW, on the other hand, has a function which words one to get the maximum items in a table in one step. I need to use Labview to 'send' the thermocouples of 50 or more to the Labview model. In addition to the variables that must be communicated between Veristand and Labview, I also need to present Labview with the threshold and setting parameters. Forums and user manuaIs understand that you must use the connector pane in Labview Veristand System Explorer mapping to expose the inports and isolated villages. The problem is that the part of Labview connector is limited to 27 I/O. How to overcome this limitation?

  BTW. I'm relatively new to Labview and Versitand.

  Thank you.

  Richard

  You can work around this limitation by putting your orders and clusters indicators. Then set the cluster to be required or recommended to indicate whether contained controls are entered or parameters, just normal.

  

• Localhost UDP connection between FCR and Matlab

  Hi all

  I have a question about the connection between Matlab and FCR UDP. My idea is to Exchange data between Matlab and Labview on the same computer.

  So I found the 'UDP Simple' of the FCR 2.0 sample project where periodically a datasample is generated randomly and sent to the remoteport 61557 local host. In the project a 'fractional number of string for transmission' is used for the transmission of data. The receiver of the sample project reads from the same port to receive the datasample.

  Now, I'm interested to read this simple stream from Matlab (just at first), however, it does not work and I'm not sure why. What I do in Matlab is the following (code Matlab)

  delete variables;
  u = udp ('127.0.0.1', 61557); % Of installation UDP Object
  fopen (u); open reading port %
  A = fread (u, 1);  % read an element
  fclose (u);

  With this code, however, I get a timeout by saying: "' WARNING: unsuccessful reading: the amount of data specified has not been returned within the time limit." "

  I'm not sure why this happens, maybe you could help me out here? I guess that the formet serving to VCF is not the same as in Matlab? Maybe the Terminators are not the same?

  See you soon,.

  Hey

  So, regarding the problem actually, I found the solution today. It was not the firewall, but a simple configuration in Matlab seting the UDP port. So the side of Matlab, to change the definition of udp object according to

  u = udp ('127.0.0.1', 'Thelocalport', 61557);

  If you have

  u = udp ('127.0.0.1', 'Thelocalport', 61557);
  fopen (u);

  A = fread (u)

  fclose (u);
  Delete (u);

  Who does the trick and you can read from the port. Then of course you say Matlab that you read from the "LocalPort" x, which I wasn't aware of.

  On the transmitter side, you simply:

  u = udp ('127.0.0.1', 61557);

  fopen (u);

  fwrite (u, '1');

  fclose (u);
  Delete (u);

  Here, you set just the port of transmiting.

  About the format of the data: I used the simple UDP protocol streaming Comms project where a random number is generated as a double, transformed into a string (ASCII values) and transmitted. At the level of the receiver, you get as much the UDP packet with the ASCII values that you must turn if you want to find the number.

  I hope this helps anyone having the same problem.

  See you soon

• 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.

• trying to get my messages text passed between my iPhone and iPad

  I try to get my messages text passed between my iPhone and iPad.  The phone asking me to enter the 'code' shown on my iPad.  Howeve, no code appears.  How should I proceed?  Very frustrating!

  Both devices must be signed with the same identifier Apple and the devices must be unlocked for the code appear. After checking both are true I suggest you try a reset (two aircraft): press and hold the sleep/wake button and the Home button at the same time for at least 10 seconds, until the Apple logo appears. -Note: no data will be lost.

• Interruption USB Raw: flow of data between USB Raw Device and Labview!

  I do the USB communication between device (Microcontroller) Labview and USB RAW. I did all the things like the raw driver OR USB and I am able to get the 8 bytes using getusbinterrupt.vi, but my application requires continuous data transfer between pc and microcontroller, inorder to achieve that I put continuous loop in the microcontroller, so it transfers the data of continuos on pc, (in this case e.g.0 to 255 and again from 0 to 255 and so on.) , but I'm not able to get increment of 1 as written in my program, instead of that I'm getting increment of 5 to 10... is it because Microcintroller is very fast as my pc? If so how can I get continuous data without breaks...

  I enclose... graphic instant with output vi this jump of the variable data... I run my vi continuously on mode...

  Like, I would also like to write to the device with labview, can you also suggest for this also? I read messages like:

  Run a quick code continuous mode is completely unnecessary.

  You can't copy + paste between versions of LabVIEW.

  You will need to save for the previous version and open in the LabVIEW version that you want to paste to.

• 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.
