• What computer affects the timestamp of a shared variable?

  What computer affects the timestamp of a shared variable? The computer that hosts the variable or the computer writes the variable?

  (This is important when the system clocks are different).

  Greetings,

  Hey,.

  The time stamp has the value of the variable that writes.

• "Not a valid error code" when you create a shared variable of data type custom

  I am trying to create a shared variable with a data type of a 2d double table. I created a custom control that contains a table with a numeric type for this 2d. Manager of distributed system v12 I select 'add a variable', then select 'of the custom control. Once select my control I get the following error: "invalid data type. You want to choose a different data type. Any advice as to why it doesn't work? Thank you.

  This seems to be recorded in the CAR #405941.  All this is a bit strange, but I'll try better possible workaround solutions I can.  I tested a large number of these myself, and here is what I found.

  1. make sure that the custom control you did was created in 2012 of LabVIEW or you save it in an earlier version.  If you save on an earlier version, you may also open the .ctl in LabVIEW 2012 and resave it (I needed to do).  I tried to create my own control in 2012, as well as save the control to a previous version, the two worked, but I don't end up with the same result (I don't understand this, but I wanted to mention it so that you know).

  2. it seems that you are able to make the variable shared by program by modifying the example of the community to adapt to your needs.  If you do not need to create many variables it may be the best option if it works for you.

  I would also try adding the variable of the LabVIEW project, you are working on that.  It wasn't a direct troubleshooting step but there are several ways of doing things in LabVIEW and, sometimes, one of them is working while the other does not.

  Edit: Example of community is here https://decibel.ni.com/content/docs/DOC-16863

• Variant in the variant of a shared variable

  Hello

  I'm re-reading some tags in a PLC Siemens S7 - 1200 OPC server of NOR. I can read them NOR-DSM (Distributed System Manager). However, I can't read or write in Labview. I generated a shared variable event loop that runs when the variable changes. I always get variant variant as a value that is not correct I want to convert to a data type. (See attached image)

  How can I fix it?

  It's okay, it works:

  IO errors are indicative of a bad drive.   It is possible, if you reformat - losing all data, you can extend the life.  If under warranty return it with a copy of your terminal error.

• All printing errors in the queue for a shared printer

  I have a HP6110 connected to an XP machine.  It is shared and the printer is installed on a computer vista laptop.  I could print however now each job is in the queue and then goes into an error state.  The only way I can remove the task from the queue is to restart the print spooler.

  How can I fix once and for all?

  Well, I never aspired to be certified MCSE on NT than a few computers existing except in places like Bletchley Park to crack the enigma code messages .

  Deleting the files in the folder is at the heart of the fixing of the problem if my hypothesis about your problem is correct. The problem is one of the frequently reported printer problems.

• Publish a queue using the shared variable

  I have a 2D table queue and I would like to publish (the reference) in a shared variable, so that I can pay the items in the queue in an another vi. I tried to create a queue control and used the custom of the shared variable control option, but it gives me an error "invalid data type.

  You try to read from the queue to another computer? Passing the reference to the queue on the network to a another computer will not allow the application to read data from the queue. The queue data is stored only locally.

  I honestly don't know why you get an error trying, however. Other options to access a queue in the world on the same machine are to use a Global Variable, rather than a shared Variable, or to get your reference queue by using a well-known name who know the other parties of the request.

• 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!

• VI refuses to run when the published network shared variable is not available

  I have a VI of logging data on my PC that gathers data from several sources, including several shared variable published network hosted on an RT target.

  The problem I have is that the data logger VI refuses to start if the target RT is disabled and the VI is abandoned if the network connection is interrupted.

  Is there an easy way to detect when running, be published these variable network are available and use a placeholder value, if they are not rather than the current behavior of refusing to work?

  I saw many people using data sockets, but I try to avoid the overhead of setting up and testing a loop of treatment relatively complex network on both ends when the network has published shared variables are so simple to use and works perfectly as this abnormal behavior.

  You can replace them with programmatic access (shared variable aperture and friends) and the dummy data placeholders if the variable is not accessible.

• 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.

• What is the blue thing in the shared variable?

  I'm going thorough a code that has the huge set of shared variables and in some nodes, I find a blue color of brand/thing left bottom just worldwide as shown below.  What this indicates?

  

  Thank you

  I found the answers of my team member.  The blue mark indicates in fact a point and a slash ". ------"which means relative sharing Variable target."  If the shared Variable is absolute, this indication does not appear.  To learn more about the difference between shared variable absolute and Relative target, check it out here.  A Shared variable node can be established between absolute and relative assistance

• How to make a shared variable, which is an update on the host channel?

  Hi all

  I'm relatively new to LabVIEW, so I apologize in advance.  I'm working on a vision for research application and I'm trying to convey an image of the smart camera target to the host.  I flattened the IMAQ image to a string and pass the string to a shared variable.  On the end of the host, I unflatten image and try to post to see if I don't really get the image data on the host.  However, it only displays the first image and after that the image is not updated.  In addition, the shared variable itself is not up-to-date.  I have a loop timed on the target and a loop of simulation on the host.  Help or direction would be appreciated.

  Thank you very much.

  I thought about it and will post here just in case it might help someone else.  For some reason, the IMAQ flatten channel gives a format that did not like the unflatten of the chain.  When I have no flat chain, it didn't recognize it as an image.  Instead, I just used the generic flatten the string on the target and then block when I have not flattened image on the host computer, I had to only give the guy I got to report the allocation of memory IMAQ.  Maybe I'm just slow, but if this helps someone else, fine.  Thanks again.

• shared variables does not

  Hello, I'm writing because I'm having a problem with the use of shared variables. I am doing a project for College and I use the DSC for his shared variable function. The problem im having is that shared variables do connect it no more. I followed a document "Getting started with LabVIEW Datalogging and supervisory Control Module" and managed to build an IOServer and shared variables in accordance with the document to deploy successfully. It was a few days ago. Today when I opened the project file even shared variables would not connect. IM also having the same problem with other projects that I made over the weekend that worked, but do not work now.

  Does anyone else have this problem?

  Hi Justin,

  I am pleased to see that you are able to work with your LabVIEW installation now. 0x0000002A error message reported only in what concerns the communication between the shared variable engine and part mutual FUND of the DSC module is blocked.  This was usually resolved by inspecting the security settings Windows for the firewall, as discussed earlier.

  As for your second question, it might be better to start a new post.  However, please specify what files you want to move and what wisely win. Where would you like the directory that is to be held and for what benefits?  If you are hoping to achieve a gain of performance or similar, there may be different approaches other than moving files.

  Kind regards

• Embedded FPGA vi - network shared variable not updated

  Hello

  I work with an ethernet RIO 9149 of data acquisition. I use a hybrid programming mode.

  I have a very simple FPGA VI that I downloaded on the flash memory. I used the indicator led to show my VI runs once the power of the RIO. Everything is fine, except that my shared network variables are not updated in the DSM ("no known values" displayed). However when I run the FPGA VI of my laptop, only once then stop and close (with 'interactive execution'), then my shared variables are updated in the DSM.

  Any ideas why is this and how do I get the RIO update automatically shared variables without having to run the VI once?

  Thank you very much.

  Hello

  I did a few tests and research and discovered that it doesn't seem to be possible. It is important to note the difference between Network-Published static (NSPV) and Variables of e/s of Network-Published.

  The other are "user defined variable I/O" to communicate between FPGA and RT (RT absent on chassis Ethernet as the NI 9149) host. If these variables are checked to be published-network (in properties). They are accessible by VI running on the hosts of the same LabVIEW project, so you need to run a VI to access, as you mention. This is explained on the next page, Variable IO data custom FPGA of e/s (real-time Module or Module FPGA):

  https://zone.NI.com/reference/en-XX/help/371361H-01/lvioscanhelp/io_vars/#user_IOV

  I did find a way without a host (host RT or Windows PC) running a VI. If you have a cRIO with RT and NPSV host in the RT VI it is possible.

• Shared variables, analysis engine and multiple targets

  I'm looking for some general tips on my LabVIEW project structure.

  The project consists of a laptop with LabVIEW, a connected joystick and a CompactRIO connected via ethernet. I ran the cRIO mode Interface FPGA, but a change in some things causes the project to have be moved to scan mode.

  From now on, the code on the portable computer updates the shared variables on the cRIO and bed from the variables shared on the cRIO for surveillance. I want to shared variables on the cRIO because he will also need to work without the connected laptop. Before moving the cRIO for scan mode, I found that I had to first run the code of the laptop and then run the code cRIO, or shared variables would not release properly. Now that I spent to scan mode, I have to run the code cRIO first, and even then the shared vars do not properly communicate for more than a few seconds and are well laggier.

  My ideal project solution is a system that can operate with or without the connected laptop and obviously do not have these questions shared variable. I would like the autostart code on the cRIO and ask the user to execute the code of the computer laptop, if necessary, but in the past, it doesn't seem to work with shared variables.

  I'm really confused about why this is happening. I hope I explained my problem well enough. I really don't want to display the entire project here, but I can email to people if they are willing to take a look. Thank you for taking the time to read this.

  I'm under LabVIEW 2010 SP1 with FPGA, DSC modules and robotic in real time. I have the updated Feb 11 driver and NOR-RIO 3.6.0 installed and completed all updated on my RT cRIO.

  I do this kind of thing all the time...

  Move all your NSV libraries on the cRIO.  Of the project, you must deploy on the cRIO and then they are persistent until you reformat.

  Your windows GUI application, you can set static NSV tags on the block schema or use the API SV dynamic R / w.  Also you can bind GUI controls and

  indicators directly to the NSV cRIO (it's what I do) also I create a library of 'mirror' in the PC HMI that is linked to the library of cRIO.  This library has DSC Citadel

  data record enable and automatically records the historical traces of all my important data - very nice.  Libraries hosted PC can be set to autodeploy in the version of the app.

  the project also has an option of autodeploy to the development environment that normally, I turned off.  If you have a PC at the cRIO binding configuration so be careful

  on any kind of autodeployment because this will eventually force the cRIO app stop when you deploy.  To work around this problem, you can use the PSP (IP address rather than project binding

  process name) and use of the DSC deploy library s vi in your HMI application.  Once you use the scan engine, you can use the app DSM (Distributed System Manager) to view, DIF and

  each of you IOV and NSV graphic on your network.
