• Open the reference vi from Labview Labview 2014 6 conversion

  Is it possible that someone can help me to convert this VI written in Labview 6.1 so that I can work in EXE in 2014 of Labview.

  I have to open this vi of 6.1 until 2014, but it does not run. The reference open vi that those do not work in program exe. Anyone know how I can replace this function...

  Thank you!

  Error 7 is file not found.  So your dynamically called VI isn't in your executable.

  In to build for your project executable specification, there is a "Source files" section.  On options for the screw is always 'include '.

• LabVIEW 8.6.1 project causes the slow open VI reference

  I have a strange problem with 'Open VI Reference.vi'.

  Case 1.

  • Open a project in LabVIEW that contains "Main.vi".
  • Open 'Main.vi '.
  • Run "Main.vi".
  • Execution of "Open VI Reference.vi" take about 2, 000ms

  Case 2.

  • Open "Main.vi" - open LabVIEW No. project
  • Run "Main.vi".
  • Execution of "Open VI Reference.vi" take about 100ms

  I converted the project to 8.5 and the problem goes away. I have not all machines with 8.6.0 to test if there is a problem with 8.6.1 only.

  Has anyone else seen anything like this?

  
  

• Open FPGA references change to no. target when compiled with executable in time real start

  Hello again you useful forum fans!  I have a problem that I hope someone can give me a hand with.

  I have a project that has a Windows component and a component of the target in real time, that are running on a hypervisor type NI PXI-8110 system.  Communication both sides between them using shared variables.

  On the real-time side, I have four FPGA targets who are reading and writing various analog and discrete inputs and outputs.  I several periods loops which opens a reference to one of the FPGA targets during the first call, then pass this reference in several subVIs that read and write to panels prior to the FPGA.  The loops the FPGA reference thus made available and reuse it in the next iteration through the shift registers.  Each FPGA target has only a single reference open to him.  One of the loops is using the FPGA reference directly and does not pass it in any subVIs.

  It all works very well in the development environment, I can read and control inputs and outputs FPGAS via the front panel of the application of the side Windows.  It also works very well if I start the game real time in the development environment, and run the code of windows as a stand-alone executable file.

  However, when I compile the code in real-time in an executable startup and deploy it to the target, it does not work.  I enabled debugging on the executable, and when I connect to it via the operation-> debug executable in the menu, I see an arrow broken at execution.  Further investigation shows that each of the four open screw reference FPGA is now empty, the text under them is "no target" and the thread for reference on their part to my first Subvi is broken.  I need your help to understand how to operate as it does in the development environment.

  I followed the instructions of these two knowledge base articles to compile and download the bitfiles FPGA on the FPGA target and execute on start or restart:

  Open FPGA reference screw are configured for the FPGA to build specifications that I created for each target in the LabVIEW FPGA project.

  I called technical support, NO phone, and yet were able to determine this one out, so additional "brownie" points if you do!  I would offer you the same no detailed screenshot that I have (I can't give more detailed code out because its owner, unfortunately), but apparently the forum doesn't like my image file, as I can't seem to load.

  Please let me know if you have any ideas regarding what is happening!  I appreciate it.

  Jon,

  I'm always up for the challenge.  Have you tryied recompile the FPGA VI that accesses the RT VI?  I also suggest to try and open the bitfile instead of the FPGA VI.  You run in dynamic mode (this is not a suggestion, it's just a question)? There is no difference if you try to open the FPGA VI reference outside the while loop, then past the reference to use inside the while loop without shift registers, then close the reference to the FPGA VI outside the while loop?

  Let me know if these suggestions makes no difference.

• It is possible to pass arguments to a VI uses "Open VI reference.

  I am modifying pre-existing code. (I say this, because there are many other ways to work around this problem, but I'm stuck with what I have)

  I have a large project that is compiled into an EXE file.

  Within this project, it uses the 'Open VI reference' in VI that is bundled in the compiled exe file.

  All good, no?

  Well, here's the question:

  Is it possible to include arguments of open type of command line with a "reference VI"?

  Where I can say "Something.vi / Option: Foo".

  

  I tried many variants such as

  ' Something.vi-/ Option: Foo ".

  even tried variations such as

  "C:\MyLVProgram.exe\Something.vi Option:Foo".

  (Interestingly, quite there no error when you do "C:\MyLVProgram.exe\Something.vi" when executing the VI reference opened.)

  This exe is deployed in a system that has only installed the runtime.

  My current environment is LV 8.6.1. (I know it's old)

  It seems that the antiderivative of LabVIEW recognizes only the paths, and in all other cases, I get an error

  Error 1026 to invoke the node in Something.vi-> MakeSomething.vi

  Possible reasons:

  LabVIEW: VI Reference is not valid.

  Any ideas?

  You can only send command line arguments to an executable with the system Exec.  If you want to pass data in VI, then use the asynchronous call with run.

• Client server of executable activex LabVIEW project with excel vba

  Hi all

  I submitted a ticket to support nor on this problem, but my deadline for this project is very close, so I would like to ask the community to see if someone has encountered this problem before (I hope it's ok that I'm doing this!). I did a fair amount of forum-scouring, and I didn't know this even discussed problem.

  I built a labView project which is essentially in the material data and
  preforms various visualizations and transformations on the data. A bit of the
  Screws in this project are available by VBA Excel as a Server ActiveX with LabView and
  Excel as the customer - and it works! I recently discovered I would need to do a
  executable version of my project, so I'm now trying to figure out how to do the same thing
  with my executable file as the server instead of LabView. Here's a simplified version are
  My VBA code:

  Void Button1_Click()
  Dim lvapp As MyServer.Application
  Dim vi MyServer.VirtualInstrument

  Set lvapp = CreateObject ("MyServer.Application")
      
  VI the value is lvapp. GetVIReference ("Main.vi", "", True)
      
  Sheet1.cells (1, 1) = vi. GetControlValue ("Path")
      
  lvapp. Quit smoking
  End Sub

  I replaced LabView here with the name of my server. The code
  failure of the CreateObject method with the following error:

  Run-time error '13':
  Type mismatch

  Things, I'm pretty sure I'm doing it correctly:
  -L'application is configured as an ActiveX server in the build options
  -J' ran the VI once and close/re-open it just after each build before trying the
  worksheet
  -In excel, VBA method is configured to reference the type library of the server.
  -J' have LabView itself closed when I run the .exe

  Thank you

  My versions and such:
  Software of NEITHER: LabVIEW version 2012
  OS: Windows 7

  It's interesting - I'll have to look into the issue. In the meantime, I found a solution.

  It's quite mysterious, but it seems that all I had to do was make sure you only the type library of the server executable has been referenced in VBA (no LabView or OLE type library) and declare the variable app as object, rather than MyServerName.Application. Honestly, I have no idea why this works, but it does. Also, I learned that you need to use the executable file paths, which are a little different than the paths of project files.

  Thank you

• Custom LabVIEW projects

  I'm trying to create a new template to be used with LabVIEW 2013 Create Project wizard. I followed the tutorial "using examples and custom models of projects to develop LabVIEW projects" but always seem to have questions.

  I'm sure it's something really simple that I'm doing wrong, but can't seem to find the problem.

  I placed the template project in the xml code in metadata/ProjectsTemplates-LabVIEW and LabVIEW/ProjectTemplates data sources data.

  When I create a new project using the wizard, the project is created and works perfectly the first time.

  Then when I open it again, there's a load of conflicts that exist all of a sudden where some of the vi are linked to the model project.

  I can go and solve all conflicts and the project works, but there must be something I am doing wrong.

  I'll be grateful for any help getting this sort. I have attached the conflicts and my xml file (I changed the extension of the xml file to attach it).

  Thank you

  Hi Larry,

  Thanks for the help.

  I had a look at my model and noticed that I had records value auto fill. I who took off in the model, and it seems to work now.

• "Open Vi reference" error 7

  Hello

  I get "Error 7" of the vi 'Reference open VI', the name of vi is wired vi entrance road. The "error 7" means that the vi is not found. I went to "Tools ===> Options ===> paths" and changed the path so that Labview can find it. But for reasons, I do not understand the vi I want to get a reference to the was not found. So it leads me to believe that the 'open vi reference' does not use the option of path to find a vi. Any ideas what's happening?

  You use a relative path. As stated in help for the Open VI VI of reference:

  If the path is relative, the VI interprets the path as compared to appellant VI or the directory of the application, if the appellant VI is not registered.

  The search path is not used for this function. If the VI isn't in the location "in relation to appellant VI", you must provide a full path.

• iMovie on El Capitan 10.11.2 crashes when opening, indicating the download of a project.

  iMovie on El Capitan 10.11.2 crashes when opening, indicating the download of a project. You have to force quit.

  It is possible that you have a corrupted project which will cause iMovie hang when it tries to load it.

  Hold down the Alt (option) key when you launch iMovie.  This will prevent that he tries to load all projects immediately and ask for a library to open it.

• Max OR simulated PXI devices that are not present in the Labview project

  I added a map of e/s digital NOR-PXI-6527 simulated to my MAX NI PXI's, but it does not seem possible to access this IO card simulated in a Labview project.

  Is this normal?

  Have sorted it.

  It turns out that on my desk and PXI data acquisition driver wasn't the same version.

  Updated PXI, and then it worked.

  See you soon

• Is there a way to determine the equivalent ANSI C code of a Labview project?

  I'm a complete newbie to Labview.  I have this quite complex Labview project that was used to create a DLL that matlab may call to order my card PCI-6534 without having to know NIDAQmx calls.

  I am trying to find how to make these calls directly from Matlab NIDAQmx, but I do not get the same results when I call this DLL mentioned above, so I thought I would try to give a sense Labview projects live I begins to make sense of the general economy of the screw, but I would like to be able to run the project , step through it and perhaps see NIDAQmx orders (or something equivalent, so I can determine how to call NIDAQmx commands in Matlab).

  Is this possible to do?

  Thank you

  Jason

  Yes. The toolbar allows you to turn on highlighting so that you can run the VI and see the content of the son. You can put sensors on the wires. You can single-step through the code. This is explained in the help of LabVIEW under Fundamantals-> running and debugging screw-> Concepts-> Debugging Techniques.

  In what the question implied in the title of your message, don't you can directly convert LabVIEW C code in the development environment. Yes, there are tools to convert LabVIEW in C, but which is intended for microprocessors.

• Open the csv file in labview

  Hello

  its difficult for me to open the .csv file in labview. If someone you suggest program labview or suspicion for bellows file attached?

  its really a challenge to open it in Labview.

  So free then try to solve this problem.

  Thank you

  Use the worksheet in reading file.  You can then use the table to Index to get the first colum and search for an empty string.  This will give you the break between the header data and the actual data.  Take all the data after this line and convert it to a number (String number floating/Exp).

• There is a possibility to run Labview projects or to set them off from a batch file or if the exist and the ability to control labview or run it from an external application?

  Hi, I m a bit new in LabVIEW and I'd like to ask a few questions...

  -There is a possibility to run Labview projects or to set them off from a batch file or if the exist and the ability to control labview or run it from an external application?

  -One API PI or raspberry beaglebone exists for LabVIEW?

  -Power supply Wich can recommend you control with LabVIEW? (some chip solution witn 0 - 30v / 0 - 3A DC)

  Thank you very much for your advice!

  Best regards

  Elena

  Elena,

  I know raspberry, so no comment on that.

  For the rest:

  -Do you want to create tools for developers? If so, we must look in the API of project VI and VI server. If this isn't the case, please compile your application LV as executable and call this one using a batch file.

  -LV prefer specific supplies. LV is a programming language. There are several power supply providers (including OR) which provide directly the LV API for their power supplies. So, essentially, the approach is:

  1. choose food that serves your needs.

  2. check if the power supply has a standard interface for programming (such as Ethernet, GPIB, or if the power supply is PXI, is already providing a programming interface!)

  3. check if the LV API (so-called "instrument driver") is available for the device. In the case of a PXI system, get you a device driver (for example NI DCPower).

  4. check if the LV samples are available (for example in the Finder for example LV once you have installed the driver).
