• AutoStart VeriStand using LabView project

  Hi all
  I want to manage through selection LabView and deployment of projects on my PXI system.

  In order to know which project is running that only, I founded the solution to create an ad-hoc ALIAS that appears at the top of the list. Is there anyone who knows a smarter way?
  Attached is my example .VI
  Thank you very much for your answers

  You can watch the NI VeriStand - Get function System State.vi located in the NIVS palette. Notably, she returns the path to the definition file deployed where he is already running a (and you can use Connect to System.vi to run a definition instead of a project file). It is perhaps more convenient than your alias workaround solution!

• CAN PXI-8461 with VeriStand using

  I have two cards CAN in my chassis: 8512 and a 8461.  The chassis has the latest NI-CAN driver installed and XI-NET 1.0.0.  I can see/access the 8512 without any problem.  I cannot see/do not know how to configure the 8461 for use with VeriStand.  Under MAX, XI-NET does not list the 8461, but I see it in PXI - 1 chassis system.  It don't will not, however, let me do something with it from there.  Any help is appreciated.

  The 8461 is map of series 2, which cannot be used with the NI-CAN driver (OR-XNET has no effect at this point).

  To begin, start in MAX the NI-CAN by accessing tools configuration tool-> NI - CAN-> RT Hardware Configuration.

  Once you have configured the flow rate in bauds, termination, etc etc etc go to System Explorer (SE), add a CAN Port and specify the baud rate according to the settings you selected in MAX. Then import the incoming and outgoing images and you're good to go...

• API in LabVIEW VeriStand using for graphics

  Hello

  I was wondering if anyone has experience reproducing graphics that accompany the VeriStand workspace in LabVIEW via the API. For example, should I use the block to get the value of channel to power a LabVIEW graph or is there another suggested method? Thank you.

  You can start by this example:

  \examples\Execution API\UDP Streaming\UDP Example.vi streaming

  It shows you how to request data in continuous high-speed gateway VeriStand and treat it. It does not show another specific feature of the graph VeriStand workspace, as the locking button, but it's a start.

• Is it possible to start the gateway of 2014 VeriStand using LabVIEW 2014 programmatically?

  Hello

  There is a reload of the Is-there-a-possibility-to-start-the-VeriStand-2011-SP1-Gateway because what worked in 2011 SP1 is no more in 2014.

  I've worn the code in the previous topic, do the same thing (calling "__cdecl Int32 StartVeriStandGateway (excluding handle Int32)" in "C:\Program Files (x 86) \National 2014\Data\NationalInstruments.VeriStand.Gateway.dll".)

  Do this from a .NET (console process or windows) program or directly from a node DLLS in LabVIEW 2014 seems to have no effect, knowing the .NET code worked in 2011 even when it is called from a Windows service.

  Is there a new way to do it?

  Moreover, the "NationalInstruments.VeriStand.WindowsRegistry.GetInstallationDirectory ()" method disappeared from assemblies.

  Best regards

  I remember before I saw this. There was a problem where the dll cannot run in the UI thread, but has no way to specify any thread, but the LabVIEW user interface thread. So, the solution was to put DLLS in a sub - VI, value than Subvi to run in the 'standard' thread and calls the value of the call to the DLL to run in any thread. See attachment.

• Mode of scanning/FPGA for a CRIO by Veristand

  Hello!

  I have a small error using my CRIO 9081 use with CAN communication, here's what I did:

  1. I use the CRIO with scan mode and customized it "Scan engine" and Ethercat for show my analog modules under VeriStand, it's ok

  2. I use the CRIO with FPGA Scan interface (together under Labview) to detect my modules CAN, also ok

  3 - then I wanted to see the CAN and analog modules, so I use this page:

  http://digital.NI.com/public.nsf/allkb/0DB7FEF37C26AF85862575C400531690

  And here's my problem:

  with this method I am able to see the two modules with the custom device 'analytical engine and ethercat", which is really nice, BUT, impossible project VeriStand, the error message asking me to turn the chassis using FPGA, but then I lost the analog module...

  So is it possible to run a project Veristand using both Scan and FPGA interface mode?

  Thank you very much

  Hi Vincent,.

  When you tried to implement, you use the procedure described in the following document in the section use of Scan Engine and EtherCAT with NI 986 x custom device modules XNET ?

  From what I remember, because you use a cRIO-9081, you will need to compile an empty bitfile for your target and place the controller in Mode FPGA hybrid mode on your chassis.

  Could you post a screenshot of the error of deployment, you see?

• Open different files to workspace with VeriStand API

  Hello, I have a question about the API VeriStand using LabVIEW. LabView is able to open a specific project of VS; now, I mean VS to open the same project file with a file from another workspace (.nivsscreen) similar like the box below, but with the API:

  

  I want to do this is because I want to open different files, workspace according to the connected equipment.

  Is there an API function to do this?

  Thank you, Michael

  There is not an API to directly modify the screen workspace or ask running workspace to load a particular screen.

  I think going that you can accomplish what you want, leaving to know the definition of deployed system but by program by selecting different workspaces to display via the API. It is a small roundabout and there are a few quirks of cosmetics that I mention below, but it's probably worth a look. I am attaching an example below, you can play.

  The main idea is to create a system definition file, and then create several separate project VeriStand files which all related to the same system definition. You can do this in the dialog box create a new project by selecting the tab system definition to use a definition from existing system rather than create a new one. For each project you create, modify the file to corresponding workspace screens for some display you like.

  Once you have done this, use execution > Workspace screws to deploy by programming the system definition file. It is important that do you rather than deploy the system through the project definition file, as I'll explain below. Then, you can take advantage of the project API screw for programmically load and close projects, as well as launch and close the workspace for this project. To view a particular workspace, just close the current project (if it is open) and load the project associated with this workspace. Then ask this project to open his window to the workspace.

  The key thing to note here is that if a project load and it detects that VeriStand bridge is already linked to its definition of linked system, it will just adopt that opens the connection. In addition, if the project is closed, it will NOT cancel the deployment of this system gateway definition connection, because it doesn't have to deploy it in the first place.

  See the example below. Just unzip all the files in the same folder and open the Automator.vi workspace. Make sure VeriStand is open before you run this VI.

  Known issues: when you switch workspaces in this example, you are in fact a project of closing and opening another. Therefore, the window began to do can do appear briefly.

• Read the story of calibration veriStand Vi file

  I need to update the scale and offset for channels to HAVE it. I'm looking for an easy way to read the stored scale and offset values from the file history of Calibration and apply them to the user channels that will be used in calculated channels.

  Is there a way to read the file Ni Veristand using LabView calibration history?

  I wrote a small tool for that earlier. Give it a try and see if it fits your needs.

• Download Bitfile to Flash on FPGA in VeriStand

  Hello

  I was wondering how to download a FPGA bitfile for flash memory on a FPGA using VeriStand. I use a PXI chassis and a FPGA PXI R series.

  I hope that the answer is

  (1) configure the FPGA VI to run when loading on FPGA

  (2) open the VeriStand System Explorer, set the initialization of the system to run a system to reboot definition.

  (3) deployment.

  Or is the bitfile stored on the hard drive to the chassis and then imported on the FPGA whenever the chassis is started?

  If I cancel the deployment of the system definition file I guess the flash on the FPGA is deleted, is it true?

  Thank you

  Brent

  Hi Brent,

  I heard R & d today. VeriStand uses the open FPGA VI reference, which means that the bitfile will not be replaced if it detects the correct bitfile already running.

  "(Par défaut pour certaines cibles FPGA, cette fonction s'ouvre et exécute le VI FPGA compilé sur la cible FPGA si le VI FPGA n'est pas déjà en cours d'exécution)." - 2012 help FPGA open Reference VI.

  When the system definition is canceled the FPGA is reset to zero, which is the default behavior of the close FPGA VI reference.

  "Farm the reference to the FPGA VI and resets the VI if no other references to the VI is open. Reset of the VI returns VI orders and States flags by default defines global variables uninitialized shift registers default values and clears FIFOs. "- 2012 Help close FPGA VI Reference.

• Simulink Inport/Outport data types

  I searched for a while and I am unable to find documentation about what types of data I need to use the inports, outport, settings and in my Simulink models.

  Is there some specific types of data that are, or are not supported?  How VeriStand to determine how to coerce data to send the model?  Also, I was under heard VeriStand uses doubles for everything but then I saw a post that says he uses of I64.

  Any clarification would be much appreciated.

  VeriStand 2013 SP1 (probably upgraded to 2016 in next year if it's relevant)

  MATLAB 2010 b and MATLAB 2012 b (currently)

  > Are there types of specific data that are, or are not supported?

  I don't remember there being any limitation of types beyond what is stated in the considerations help document.

  Considerations relating to the integration of The MathWorks, Inc. Simulink® software models (model Interface T...

  The big hiccup I remember wasn't mainly with types of configurations and data bus.

  IIRC, you can choose any numeric type desired in Simulink. The structure of the model interface that uses VeriStand will handle any type and convert it to double so that it can be consumed by the VeriStand engine.

  > How VeriStand to determine how to coerce data to send the model?

  I think the way it works is that when VeriStand interacts with the Simulink model, it gets a list and information (pointer, data type) of inports, remote villages and settings. Thus, it can capture data from the model (because it has the pointer), and it can cast its data type (because he knows the type) duplicate. If you look at the example model model interface on line 212 it might help to make things more clear on how this could work.

  C:\VeriStand\2016\ModelInterface\custom\examples\template.c

  Double USER_GetValueByDataType (void * ptr, int32_t subindex, int32_t type)
  
  {
  
  	switch (type)
  
  	{
  
  		case 0:
  
  		{
  
  			/ * double * /.
  
  			(double) return (((double *) ptr) [subindex]);
  
  		}
  
  		case 1:
  
  		{
  
  			/ * only * /.
  
  			(double) return (((float *) ptr) [subindex]);
  
  		}
  
    	}
  
  / * return NaN, ok for vxworks and pharlap * /.
  
  	uint32_t nan [2] = {0xFFFFFFFF, 0xFFFFFFFF};
  
  	return *(double*) nan;
  
  }

  I'm guessing that the full implementation of which uses VeriStand is much more complex, but I think that the idea is the same.

  > Also, I was under heard VeriStand uses doubles for everything but then I saw a post that says he uses of I64.

  VeriStand engine uses indeed of all double rooms.

  You happen to remember this post and you can share the link? I'd be curious to see where this is said and in what context.

• is it possible to deploy log status of the API?

  Hello

  I made a deployment utility that allows someone to just deploy a sysdef file without using the GUI veristand. They can select IP addresses for each target, the calibration files (optional), and click on deploy. Works very well. But see all I have is a curor occupied during deployment. Is it possible to get the text, thanks to an API, by using the graphical user interface veristand would normally show?

  Thank you!

  Yes, absolutely. VeriStand uses this exact event to fill its state information. I don't remember what it's called, but if wire you a reference IWorkspace2 in a register for event reminder node, you should be able to find it quickly. Something like GatewayNotification or status.

• Units in the Stimulus Data Logger profile editor

  I have an active Veristand application that uses the data logger built in Stimulus profile editor. Recording data works fine but it does not display the channel units. This becomes a big problem with our client.

  I suggested to change the channel names so that they have units in them. Before we go on changing over 100 names of channel and dealing with the associated benefits of doing this, I would like to know if there is a way to get the units of the string to display in the data logger.

  Before, it was suggested, I already use the recording custom device of embedded data and I hammered him to the gills.

  Has anyone concerned with that? Don't know a good workaround solution?

  Thank you!

  We have a patch for this NI VeriStand 2011 SP1 if you have access to this version. The problem is that VeriStand using incorrect property name for the property units. Channels are registered with a property named 'Units', then it should be "unit_string" so that the other products like the tiara to interpret it correctly.

  You can apply an INI token to change this behavior in 2011 sp1. Add the token following in the file below.

  Win7:
  C:\ProgramData\National Instruments\NI 2011\NI VeriStand.ini VeriStand

  WinXP:
  C:\Documents and Settings\All Users\Application Data\National Instruments\NI VeriStand 2011\NI VeriStand.ini

  [NOR VeriStand]
  LogUnitsPropertyName = unit_string

• Using Simulink in Veristand for Dummies

  I'm still new to Veristand and even recent Matlab/Simulink...at less their latest incarnations.  Does anyone know a good resource "Simulink for Dummies" online?  Especially suitable for someone who is going to need to generate the code in such a manner to Veristand can make use.  I hesitate to ask for example of code, that I frown on that, but I'm really just interested in the methodology, not the code itself.

  Dan M.

  Hi Dan,.

  For information began, you will find very useful information in aid of NI VeriStand here and here. The time when we see the biggest problems is a function S faces she who calls in custom code that can run on a system in real-time (usually a DLL dependency problem) of NOR. There are times that you can use an add-in you is a model that will enable mapping to 3rd party hardware. In this case, you want to replace the input/output with VeriStand In and Out blocks so that you can use VeriStand to map material (e.g. CAN).

• Use of custom in Veristand files

  Hi all

  Have not been able to find a lot of documentation related to the use of "Personal files" in Veristand.  I would like to know some examples of the types of files users have set up.  Specifically, I would like to know if you can "call" some types of models or devices personalized (i.e. for databases or configuration settings).

  Thank you very much

  GSinMN

  Hi GSinMN,

  It has custom there some documentation in the help of VeriStand, which deals specifically with files.

  Adding custom files

  http://zone.NI.com/reference/en-XX/help/372846D-01/VeriStand/add_custom_files/

  Although aid is not quite fully reveal the capabilities of this feature. There are two distinct use cases that I could identify for the custom in VeriStand files option. I'm going to the list of people the more detail and show you an example.

  Make easily accessible to the driver files in the development environment.

  When a file is added in the custom files in the project section, it will have its own icon in the project and is included in the project dependencies. Having the file to display in the project is useful if there is a picture of troubleshooting or a specific document (calibration sheet, how to run a test, etc.) that you would like as your operator to have access to. For example, in the sample project, I realized, there is an added file called "TestA1_PreTestSetup.txt". Of the project (on the toolbar), the operator has the option "Open a file" (to view) or "export...". "to investigate his path on the computer of the operator.

  

  Please note that the file is now added to the dependencies of the project.

  If you start to investigate the project file and lets say you do a right click on it and notice that there is a Properties option. You may notice that the Description of this file is empty. In fact, it can be filled by modifying the XML source of the .nivsproj. It also leads in the second case of the use of custom files.

  Transferring files to the aim of RT which can be used by the VeriStand engine.

  If you were to investigate the .nivsproj XML, you could first find the section of the custom files, then the tags of the element that you configured.

  

  Here are the relevant tags and a jump down,

  -It points to the source of the custom file. In this case, I added the file in the directory "C:\Users\Public\Documents\National Instruments\NI VeriStand 2011\Test procédures". He is able to solve the first component 'In common Doc Dir' because it's the common directory for VeriStand, and he added then the folder of the test procedures and the name of the file that I created.

  -Fill this tag gives us the opportunity to complete the description information that occurs when we right click on the file in the project.

  -Fill this tag gives you the ability to also send the file to the target deployment. Your VeriStand engine can then access this file during the operation. With respect to the types of files that you want to use, the link in the post above should help guide only.

  Please Note: change the XML of the project offers more customization and functionality of your project, but these changes should not be made whole. An incorrect change tags in the XML file can lead to results and poor execution. Then move forward with caution and only make minor changes at the same time.

  I hope this helps. Have a nice day, GSinMN

• Deploy and use the shared library in VeriStand for several VCD

  Hello world

  I'm using LabVIEW 2011 SP1 and VeriStand 2011 SP1.

  We have developed many custom features that use a shared code (C++ and LabVIEW code).

  For now, there is a copy of the C++ shared in each custom device dll.

  The problem is when we change the C++ dll and we forget to copy a new one to each custom devices, the oldest one that can be used by each custom devices.

  We would like to do is not to have only a single dll shared in a specific folder.

  My questions are how we can deploy this dll to a specific shared folder in VeriStand?

  Is there a specific folder that we can use to do this?

  Is it possible to deploy using the measurement and Automation Explorer?

  If someone has an idea, you are welcome!

  Best regards

  You can display this question in another forum that I don't think there's anything directly to do with NI VeriStand.
