• How to use the 'Get Shared Variable list' VI on a target RT?

  Hello

  I would like to browse all variables shared in a library hosted on my CompactRIO programmatically. I dropped the 'Get Shared Variable list' VI in my VI in real time, but when I tried deploying, LabVIEW says

  Deployment PRC_GetVarList.viPRC_GetVarList.vi loaded with errors on the target and was closed.
  LabVIEW: Unable to load the shared library dscProc.dll:ni_lvdsc_process_GetTagListEnd:C. ensure that the library is present on the target of RT. MAX allows you to install software from OR or FTP to transfer custom RT target libraries.
  LabVIEW: Unable to load the shared library dscProc.dll:ni_lvdsc_process_GetTagListBegin:C. ensure that the library is present on the target of RT. MAX allows you to install software from OR or FTP to transfer custom RT target libraries.

  I watched the wizard of the MAX software, but cannot find the DSC-based modules. Where should I look?

  Thank you!

  Hello

  The palette of DSC is not supported on the screws in real-time and will lead to errors when they are deployed.  Unfortunately, to have a successful build you will need to modify your application and remove the screws from the palette of DSC on your target of RT.

• cRIO, shared Variables & stand-alone application

  Hello!

  I developed an application very simple acquisition of analog (NI9215) and the activation/deactivation of outputs signals digital (NI9472) using a cRIO (9012). Data are transmitted to the host through shared variables program.

  I created an executable of the code to be run by the cRIO, set it to the "launch on startup" and it worked.

  I did the same thing with the hosting program and created an exe installer. As I use variables shared the result of acquisition of pipes, I have them placed in the support directory (data) when you generate the executable file (Distribution.exe).

  This executable works perfectly on my computer.

  I used the Setup program to install the program on another computer. This computer as its IP address in the same subnet as my computer. But shared variables ever offer data other than their default values so I guess there is a problem of communication...

  Can someone help me?

  Hi zyl7,

  Thanks for the post!

  This is a common problem - I think...

  The problem is that you need to deploy two seté variables shared by two of the llb. You need 'real' variables on the cRIO - and deploy manually (see link) and a second llb on the host pc, which are related to real variables on the cRIO. This is because the local computer get variables shared, which of course are not those with the cRIO data locally.

  Perhaps in clearer terms.

  When you make an exe of a project using shared variables, you must have a local copy of the variables on the deployment computer which are then related to the 'real' shared variables stored on the target - cRIO, in this case.

  This means that in the view of your project:

  (1) Create static variable in the normal Manor on the cRIO.

  (2) create variables shared on the host PC - llb under the Pc host in the project and then select the aliasing and how to link to YOUR PSP.

  Let me know how it works,

  Kind regards

• How to locate where the shared Variables are used in the project.

  I'm looking everywhere where a shared Variable is used in my project. Right-clicking does not provide a find. The display hierarchy does not help. In the Project Explorer, the appellants find displays only the names of the screw called, not the many places where the call is made.

  Does anyone know how to find the location where a shared Variable is used?

  Edit-> find and replace. For "Select object" click and access features-> Structures-> shared Variable.

• How can I create a shared variable to store the data of 2D image?

  I would like to store as a shared variable 2D image data, but there is no data type to do! How can I do?

  You will need to use the picture to Pixmap VI to get a set of image data that you use with a shared variable. Take a look at the other screw in the photo on the block diagram features palette.

• shared variable of mutual FUND not updated of DSC

  Hello world

  I have some problems with shared variables and the OPC Client IO server functionality in Labview 8.6.1. I have the DSC module installed as well.

  I use a lonworks OPC server a company called us. I am able to monitor my traffic lonworks successfully using this software. I set up a server of e/s of Client OPC called Lon server in my library. From there, I've added a shared variable called nvoUI [1] in a simple VI. When I run this VI, I get no errors or warnings, but I have also no output, either in the data field or the timestamp. I read a lot of documents on the forum and knowledge base, but I could not do this work.

  I have attached a picture of my setup project and in my opinion of OPC server, along with a photo of my diagram VI and the front panel. I hope someone can help.

  Thank you

  Just to wrap things:

  I realized that my problem was multi-party.

  (1) suggestion of the cancellation of the deployment of all of my libraries deployed Charlie was a good, I got a lot of active libraries which were all referencing the same variables on my OPC server, which may have caused problems. I knew not that libraries remained deployed, a bit silly, I assumed that they were cancelled when the associated project has been closed.

  (2) I didn't know at the time, but I had several copies of my OPC server on my local machine. A copy has been started automatically in the background when I started to labview. It does not appear in the taskbar or system tray. I only found it by looking in the Task Manager.

  By cancellation of the deployment of my unused libraries and a second instance of my OPC server won't start not, I could get my shared variables to work properly. Thanks for your help Charlie.

• How to deploy taskflow as shared library and register as a producer of portlet

  Dear all,
  
  
  I have a taskflow using some popup dialog boxes to get feedback from users.
  
  
  I noticed that when I have this deployment as a portlet and then I created a page and then unmold the portlet
  in this document, I note that the popup is only inside the iFrame portlet. Not sure but I think it's normal.
  
  Research on the forum, they say it is better to deploy as a library shared on the webcenter spaces so that
  the popup not be limited on the iFrame portlet but rather to be displayed in the window of webcenter together.
  
  But I don't know how can I deploy this taskflow as a shared library and then save it as a portlet on my groupspace producer?
  Googled around, but can't find a good resource on how to do it.
  
  Sorry for my newbie question...
  
  Thank you.

  To be clear, if you plan to use the ADF taskflows directly in spaces, you do not save a producer of portlet. You deploy the taskflow as a shared library and add the taskflow to the catalog of resources.

  Hi Laura, thanks for the link.
  Just one question though, if I deploy my example project as a shared library and then save it as a catalogue of resources. Can I automatically deposited as a portlet in my pages Webcenter spaces?

  Thank you

  Yes, you add the taskflow via the mode of the composer.

• How to deploy a VO Bind variable to get the value of user session...

  Hello everyone...
  A JSF Page has a table based on VO with two parameters. One of these parameters, I'll go through the ExecuteWithParams operation.
  but the other setting, I need to pass a value of user session.
  Is this possible? How would I do that? I m using jdev10.1.3
  Thank you...

  When you create a link to executeWithParams in your pageDef, binding action should have NamedData elements for each of the parameters. These would be allocated a variableIterator to the top values in the executables section. The parameter that gets its value from the user input should be left alone. For the parameter that gets its value from the session of the user, change the EL expression that defines its NDValue attribute so that it references the session information that you want to use. This may be a sessionScope variable that you defined earlier in the session, according to Frank, a property of a bean managed in session scope, or other variables.

• How to set permissions for sharing by computer/object and not by the user, share Mac and no Windows Pc

  I wonder if anyone knows how put share permissions on an object such as a Mac in my case instead of the windows user.

  We do not have our Macs in Active Directory, we seek to share an external hard drive only Mac and not the Windows PC on the network using active directory. I tried sharing the hard drive of a PC to anyone and both PC and Mac can access to this, but we do want Macs to see and access it and not everyone. There is no selection shares with the name of the computer in the share permissions, so the only way to do is share it to everyone. The Mac, accounts are local to the Mac and the PC on Active Directory, so what I do is have a way to share this folder with only Mac and all the Windows PC. All solutions, all ideas will help.

  Thank you

  One thing I can suggest is to share the hard drive of a Mac and make sure that the hard drive is formatted in HFS file system + and not NTFS. Windows does not recognize HFS +. In this way, Windows users will not be able to access the hard disk.

  Alternative methods may be available with Mac. Please contact Apple support in this regard.

• published RT cRIO-9030 with network-a project of shared variables cannot communicate with host VI when compiled and deployed as executable startup.

  I have a project including a VI RT running on a cRIO-9030 and a host VI running on a desktop computer.  The two programs communicate via shared variables that are hosted on the cRIO.  As shows, when I run the screw of the project, everything works as expected.  When I compile the RT VI in a start-up executable can deploy for the cRIO, as well as the libraries of shared variables (the record of support in the build specification-oriented), I am unable to connect to the executable running in real time.

  

  I have 'Disable Autodeploy Variables' checked on the cRIO target, if I no longer get the prompt to stop the currently running application to deploy the variables.  The host VI opens and appears to run, but has no connection with shared variables (data does not update).  Compilation of the host VI as an executable file and it works outside the project result in the same behavior.

  I read some relevant posts / knowledge base articles related to this problem, but still can't seem to find a way around it.  I note a number of articles on the series in double bond of variables, but this is in contradiction with my possible behavior for this system: I finally have a number of cRIO controllers identical all runnning the same executable RT and want to be able to have a single host VI which allows the user to select from a list of available controllers (using the screw system configuration) and extract the host name of the controller selected, that would be later used for programmatic addressing of the variables on the host of part VI.

  In any case, I want to start with the simple fact of being able to get that first controller running without an open connection to the RT VI project.  With the deployed executable start, I checked via programmed behavior of LED application of the RT and FPGA are running on the cRIO.  The problem, I think, has to do with shared variables, but I'm not sure where to go from here.  I want to connect to RT executable running from the VI to the host (in project) to verify that the compiled executable of RT works as expected and then the subsequently compile host VI in an executable that can be run from any desktop on the local subnet.

  Thoughts?

  It seems that the error has now been corrected.  There were three things, I changed: the file startup.aliases in the startup on the target directory (Home: / lvuser/natinst/bin) put in 'localhost' as an alias for the controller.  I changed it to the IP address of the controller.  Then, I got some features of IO files in my application RT relative paths using the path obtained by the 'current path VI' VI.  As this path changes according to the location / delivery system, I had to create a VI that has used the Application property: type with a case properly structure band / build railroads desired regardless of the runtime system data files.  This may have broke my RT request.  Finally, I got a property node in one of my RT SubVIs, who attempted to change an indicator in the Subvi, which is not taken care of in an RT compiled executable.  I can't do this for debugging purposes somewhere along the way, but in any case, I removed it, and after a recompilation and the deployment of the executable of RT, everything seems to work as expected today.  The host VI on the desktop can connect to the application of the RT project, and when it is compiled into an executable file, which also works.

• VBAI: How to read a shared variable?

  I'm doing my inspection to do things that depend on the value of shared Variables. How to set the VBAI Shared variables, it is obvious, but I didn't understand how to read them and then create some kind of a structure of MATTER using this variable.

  Any ideas on how to implement such an architecture?

  I create two different States and use the transitions that are based on the value of the shared variable. You can read the value of the variables or the previous measures in stages that allow this (not all stages, but most don't) or transitions. To create a new State, go to the state diagram (click on the 'toggle window view hand' so the State-transition diagram is in the main part of the window). Right click in an empty part of the state diagram and select "create a new State".

  To create a transition, right-click on a State and select 'Create a new Transition' and drag the transition to the new State.

  To change the transition, double click it and you will be able to select the shared variable as measurement, and comparison operations to make the decision. If this comparison is false, the default transition is taken instead.

  Select help > Show context Help if you change the schema of the State for more details on how to use it.

  Hope this helps,

• Sharing Variables economy on cRIO

  Hello

  I have a cRIO with a prog to RT. There are a few variables shared network that are hosted on the cRIO.

  I can update to a host application.

  If I reboot the cRIO, shared variables return what they have lately been defined.

  If RIO loses power, then is restarted, shared variables will come as soon as they were last record, not necessarily what they were the last updated also.

  Seems like a normal restart, shared variables are registered as part of the judgment, but on a sudden loss of power, they are not.

  Y at - there a command that I can send for the cRIO to force that he record it is common shared the values of the variables so that if she loses power it will restart with these values?

  Thank you

  Paul

  There is really no way to do what I know automatically.   The only reason SV persists between resets of RT is because SV resides in another

  process tagger.exe which continues to operate through a reset.  State of the SV is only saved in ram so it gets wiped out on a power cycle.   You will need to write code to read all of your OAS and then disk-based backup/restore.  As an alternative, I guess you could eventually save the State in the ownership of the initial value of the SV, which could then be saved-Flash and of course then would automatically restore as soon as voltage.

• CompactRIO RT (:-65589) error code: error or warning occurred when writing the following shared Variable)

  Hello

  is anyone know this error Code:-65589?

  This error says:

  Shared in environmental_logger.vi variable
  This error or warning occurred when writing the following shared Variable:
  CompactRIO Target\Mod2\DO1 \\RT
  \\localhost\Mod2\DO1

  My cRIO9073 has 3 modules:

  MOD1: 9203 HAVE,

  MOD2: 9472 DO,

  Mod3: 9265 AO.

  When I delete all States and run only the first "init" State where I put DO0 = true and DO1 = false, I get this error. What could be?

  I think we need more information about your project - you can take a screenshot of your project LabVIEW RT target and the location of the shared variables? What is the configuration of the shared variable? Do you use the cRIO Scan Engine or FPGA (or both?)? How you deploy your library of variables? You should also zip to the top of your project and join, if you can.

  Here are some articles about the possible causes:

• Can I combine global shared variables libraries?

  Whenever I add a Global Variable of shared, another library without title (lvlib) is added to my project.  I now have 11 of them!  These can be combined in a library?

  Yes.

  I don't know how you have created your shared variables.  I imagine that if you a higher level of the project, it creates a new library and a variable it contains.

  If you create a new variable by right-clicking on an existing library in the project, you will need to place the new variable within this library.

  If they are all "Untitled", this means that they have probably not yet saved.  You should be able to drag one library to another in the Project Explorer window.  Don't forget to save the final library.
