At wich moment a RT controller deploys network Variables?

Hi all

I want to know when the shared variables are accessible on a RT PXI controller?

During the system startup PXI to my request for RT (defined as auto-start) first wants to write the default values for variables.

Here, I get the error:-1950679035

This means that the variable is not deployed jet.

I understand that it takes more of 5 seconds until the variables are really ready to read or write.

For the moment, I use a work around:

A network variable 'RT_System_Ready' is played repeatedly until the error has disappeared. This loop takes more than 5seconds.

After the loop starts the main application and I no longer get the error...

I think the boot sequence for the RT controller should only start the user application when all libraries are deployed and variables are accessible.

Greetings,

Henning

Hey, Henning.

No, the bootsequence cares variables, drivers or anything else to be ready, that is used in the application.

Interrogation of a flag or until the error is gone or waiting for a - and - time is the only way to get that everythings ready!

  • network variables

    Greetings,

    I wrote an application that uses c# VS2005 and Measurement Studio 8.5 to control a test Chamber.

    I would like to monitor some settings on a network or the Internet with network variables

    on a remote computer. I have to install Measurement Studio on the remote computer for this

    to work? Or just install some assemblies with a msi installation file?

    Thank you

    SThompson.

    Hi SThompson,

    As the network variables are not a component of measurement studio, you won't have to have it installed on the remote computer unless you plan to debug and recompile an application developed in Measurement Studio.  To deploy the network variables, simply enter the correct merge your installer module:

    Once you create the Setup project, simply add the MStudioNetworkVariable.2005.msm merge module located in the program directory Files\Fichiers communs\Merge Modules for the project. Add this merge module also adds necessary additional dependencies. This step is necessary in order to collect and deploy all the dll and files for the underlying network variable.

  • How to use network variables to transfer data structure C?

    I found a CNVStruct in CNVDataType.

    When calling "CNVCreateScalarDataValue" I always get a message error "the data type is incorrect.

    Hey Vincent.

    You can send some types of structure, but must be in place.  Because your structure contains arrays, you have a building yet more to do.  It should look like this:

  • Sharing network Variable not in Distributed System Manager

    I have experience with LocalHost.   I have 2 computers A, B.  A, I can read a created/static SNV of B.  However, I need to use a SNV on A to A (I don't know why, I inherited this project and it is not at all commented).  So I create and I see it on my drive D:\\.  However, when I go to NI DIstributed System Manager, there are no library under localhost.  So I write in a VI and call it in another, and I get "DataSocketRead in VI" with the code 56.  Don't know why I can't have it is the Manager.

    I have attached ahev the library in case something wrong here.

    Have you deployed and right click the shared variable library?

    If it's an executable in the bulder properties you should check to deploy shared variables.

    I have worked with Kellis Application Engineering and she determined that the shared variable engine had not begun on the CFP.  She had me reformat the CFP, reconfigure and reload the software of the PSC.  After that, I was able to deploy my variable library shared to the CFP.

  • Network Variables custom control Option Disabled

    Hi all

    I am creating a network variable in a cRIO project using a predefined custom control... I've done this hundreds of times before in other projects... For some reason any "custom control" option at the bottom of the drop-down list data type is disabled...!

    I'm sure it's something very simple, but I'm well and truly stuck now... I'm not still connected to my RIO? I have not activated the network connection again...

  • Published the network Variables not accessible by other computers on the network

    I am trying to create a system where a computer will display network variables that can see any computer on the network, this includes a person bringing in a laptop computer and the connection for a short period.  So I was looking through a large number of forums to find an answer and tried many solutions and nothing has worked.

    This is where I am.  On a single computer if I update a variable network it appears on the DSM NOR (Distributed System Manager) under which the name of the computer and I use this variable and it is updated.  Any other computer connected to the network also appears on the DSM.  On the other computer, he sees the first computer in the DSM, but cannot see any one of the variables.  I also register the IP address of the computer, but it does not help.  If anyone has had this problem and know how to fix?  I had the same problem using my code for the project and the example code in the shared Variable Comms between Executables.Ivproj.

    Thank you for your time

  • Network Variable string array

    Hi all

    I'm working on a project that would require one program to talk to another (same computer) program, where the use of the network variable.

    Now say that I have a list or a table of names that the changes in a single program, what I would do is to take parts of the list that is in a single program and transfer parts of the list to another program.

    The list must be transferred at least 40 unique names of different sizes with letters.

    I have data tables ready I just need to understand the part of the transfer.

    I tried the 3D.sim, but it seems to be a problem when I'm with strings, especially when the strings are of different lengths.

    Also when using the CNVCreateArrarDataValue errors on table place being small on the size of the array?

    String array lists are usually 2D (line and size) does that factor in?

    Assume the network variable is declared

    code exp just to get the idea...

    int i = 0, numItems = 10;

    Data CNVData = 0, NVlist [120]= {0};

    size_t dim= {0};

    size_t dim2 = {0};

    for (i = 0; i<>

    {

    char name [20] list = "0" / "."

    GetTabelCellValue (Panel, PANEL_LIST, MakePoint(2,i), name of the list);

    Dim [0] = strlen (listName);       I tried size_of but definalty did the Sun big

    CNVCreateArrayDataValue (& NVList [i], CNVString, name of the list, 1, Sun) ///i get questions of size table here

    dim2 ++;

    }

    CNVCreateStructDataValue (& data, NVList, dim2) ///here is another problem with dimensions

    CNVPutDataInBuffer (handle, data, 2000);

    I also tried

    for (i = 0; i<>

    {

    char name [20] list = "0" / "."

    GetTabelCellValue (table, list, MakePoint(2,i), name of the list);

    Dim [0] = strlen (listName);

    CNVCreateDataValue (& NVList [i], CNVString, name of the list)

    dim2 ++;

    }

    CNVCreateStructDataValue (& data, NVList, dim2) transfers of value of string ///one

    CNVPutDataInBuffer (handle, data, 2000);

    I think I'm close, but just can't get the right sequence

    Thanks

    lriddick,

    You can write an array of strings easily, but it must be an array of strings. It cannot be a two-dimensional character array, which is not the same thing. For example, the following code should work (I replaced your table with a table called "table", but the rest should be the same). Note that I have create only a single CVNData, not a picture of CNVData:

    char * array [] = {'one', 'two', ' three', 'four', 'five', "six", "seven", "eight", "nine", "ten"};
    char * name [10] list;
    CNVData = 0, NVList data;
    size_t dim [] = {10};
    for (i = 0; i<>
    {
    name of list [i] = malloc (strlen (table [i]) + 1);
    strcpy (name of list [i] table [i]);
    }
    CNVCreateArrayDataValue (& NVList, CNVString, listName, 1, Sun);
    for (i = 0; i<>
    free (listName [i]);

    CNVPutDataInBuffer (handle, NVList, CNVWaitForever);

  • network variable will not work with VBAI 2010 and windows 7

    Hello

    In fact, I have a problem with 2 EVS-1464 (windows 7) and VBAI 2010.

    I have to use network variables to allow the communication between two electric vehicles, but I can't use it. My network is ok (I can ping between the two facilities) but I can't (t access the network variable.

    I did a test with VBAI2011 EVS / VBAI2010 PC windows XP--> it works. (but I don't want to use VBAI 2011).

    You have solutions to solve my problem?

    Hello

    Here are several documents that might be useful for you:

    Using the LabVIEW shared Variable

    Troubleshooting network-published static Variables

    How can I use shared Variables to transfer data from Vision Builder for Automated Inspection (VBAI)...

    You can also try something. To do this, you must go to the EXE VBAI here:

    For 32-bit machines:
    C:\Program NIUninstaller Instruments\Vision 20XX\ VBAI

    For 64-bit machines:
    C:\Program Files (x 86) \National Instruments\Vision VBAI 20XX\

    Right-click on "Vision Builder.exe", and then select Properties.  Make sure "run this program as an administrator" is checked.

    Click OK, and then try to rerun VBAI. You may need to redeploy the variables in the variable Manager until they work properly.

    Kind regards

  • reconnect the stall network of shared network variables

    I have a cRIO unit communicates with a laptop using shared network Variables, one of them being a table of 21 index which is buffered.

    The system connects and communicates very well, but sometimes the wireless laptop card is to lose the signal from the WAP, attached to the cRIO.

    In this case the network never shared Variables "reconnect" and start to receive values still once the wireless link is restored.  Is this expected behavior?

    When I tried to use other WAP industry instead of the card laptop wireless, I get no abandonment.

    Hello Ryan,

    Please contact National Instruments!  I looked into the problem you are having and I wanted to ask you a few questions more.  First of all, you have a period of time which allows the reconnection?  I believe that the Shared Variables should find the connection after a short period, but it may not be a very quick process.  It may take a few minutes to the Variables shared to reconnect.

    The other thing that could happen is if you have error son being passed by shared Variables, it is possible that the error is not be deleted, and so he will always see the error and not a so never reconnect.  In this case, you will need to filter this error and then clear the error in order to use again shared variables.

    If you have more specific information about your program that can help us to determine the reason for this behavior.  As a screenshot of your code would be useful.  Please let me know if you have any other questions and I'll be happy to help you.  I hope this helps!
