• Browse the contents of the hard disk of the target in real time

  Hello

  Is there an easy way to browse the content of the hard drive on a real-time target by using the file path control (or another type of control)?

  What I have in my application is a PC real-time desktop (running on PharLap) who has a Main.vi running on it. There are a few configuration files (for this VI) I want to be able to read and record to that would be stored on the hard drive of the target in real time. However, when the application runs and I hit the Browse button, it displays the contents of the Windows machine and not the machine in real time. Is there something I'm missing?

  Please note that I can send via FTP on the Windows computer to the target in real time and can interact with the drive of the target in real time without any problem.

  Thank you.

• Dialog box to open the file on the target in real time

  It is possible to load data from a file on a local PC to a VI runs on an RT target? I have a RIO OR the VI running on. From the front panel, I want to be able to click a button and have a dialog pop up where I can choose a local file to load data from. The problem is that when I try to use the spreadsheet VI load data it returns an error indicating that the dialogue has been canceled. If I use the express VI from file dialog, the VI will always return true to cancel. The dialog box never appears. It is not possible to open a local file to a VI runs on a real-time target?

  This function will not work in time real (RT).  Please see the bulletin 2S9D21OH knowledge base: creation of a dialog box file for use with LabVIEW Real-time for more information on this.  However, it only locates the files on the target of RT.  If you try to communicate with a file on your host computer, you can be forced to transfer this document to the target of RT, or implement a different architecture for this task.  I would also add that given the user to define the source of the file manually create non-determinisme within your system.  Again, it is perhaps another reason to implement a different architecture.

• How to read the text from a DOS window in real time?

  I call an executable file that downloads a file to flash memory.  This program displays status information in real time as the percentage of completion in one window BACK.   It also makes account of the CRC of the file as it downloads.  I am currently redirect the output of the DOS window in a text log file.  This works fine for obtaining of the CRC when the file is actually downloading but the operator loses the visibility of the State in the percentage of download.  Is there a way to read text information in a DOS window with my request of LabWindows/CVI real-time?

  Hi Brent,

  If redirect you the output from the first application in a log file, you would be able to read the contents of the file streaming to your second request, and whenever the content changes (such as the download value percentage), couldn't display you this information immediately with the second request in one window DOS or some other GUI?

• Photo of Pixmap vi on the target in real time

  I need to shoot some simple pictures in real time and display by PXI. The image is drawn with the functions of images in the palette of the graphics and sounds. To view through PXI, I found the RT IMAQ video output in the NOR-VISION package. So I need to convert the type of type picture IMAQ. I searched online and it seems these conversions all requires the 'Photo to Pixmap' vi, which I cannot find on the aim of RT.

  Is there another way to convert the picture in picture IMAQ without using this VI?

  AuZn,

  The picture to Pixmap VI is not supported on real-time targets. The only other method I can find to get the pixmap cluster is to use Image 'Get' invoke node. However, if you plan to build this application into an executable, invoke node won't work anymore, as façade elements are removed in executable RT.

• Register the event on the target in real time using LabVIEW 2012

  Hi all,

  It seems that LabVIEW 2012 RT does not support user events. Screws are not in the range of function and the help of LabVIEW says that it is not supported. In LabVIEW 2010, everything seems fine.

  That's happened? We need this feature.

  Thanks in advance.

  Hello

  Thank you very much. We will use this workaround, which is not a lot of work if you know what to do. Develop a VI on workstation and the execution of switching left target to the low edge also implements the correct block as well as feature diagram objects.

  This can be fixed in the next patch-Patch because a lot of users could by irritated by this behavior?

  Thank you

• Slow down the host Communication target in real time

  I start with Labview RT.

  I wish that tor gave reading a thermocouple signal, then sending to host VI. It works, but to slow down.

  I tried to look at CPU, memory usage, but it's my second problem. The DSM does'nt contain functions should be.

  Am I missing a special configuration?

  

  

  Published network shared Variables are slow, especially in a high-traffic network.  I recommend that you use a network stream and set up your own communication scheme capable of handling the output rate higher.

• Need help recovering data of the target in real time. Using NI 9233

  I have a cRio-9012 with 9233 module. I have recently setup of the software for the computer and the target. I have also gone through and set up the "NI 9233 start-up scan mode" to use on my controller. However I couldn't really get the execution of vis data. Could I have missed?

  The VI is executed, but it reads zero while I use an accelerometer (Wilcoxon research model 797-33).

  You should consider the specific\ni of Labview\examples\compactrio\module 9233\ examples.

• How to overlap the 2 images of data acquired in real-time?

  Hi all

  I'm now a measure of the FRET in the laboratory. 2-channel data are acquired and shown in 2D images separately analysis by using Labview. They are at the same scale and pixel. Now what I want to do is to put them into a single image, but the signals are shown in two different colors.  Or in another word, cover them in the same image. How this could be done? BTW, I now work with LabVIEW 6.1 (I know this is a pretty old version, but since the work earlier are to do with that, I have to stay with this version). Thanks in advance.

  Dear Franceing,

  I have studied your request, but I'm not convinced that you need to stay with the old version of LabVIEW. You can upgrade to the latest version of LabVIEW, but in this case you need to upgrade your nationalities created in version 6.1 Traoré. This could be quite a big job (if you use a lot of 'old' vi), but will give you the latest features and ease of use of LabVIEW 2009 in return.

  For your question, you might think using the function "IMAQ And.vi" (if it is available in your version). This function works as a logical AND (or NAND) VI and merges the two images together.

  I hope this will help you develop your application!

  Best regards

• where the daqmx on real-time target files are stored?

  Hello

  I'm working on an application that is embedded in a desktop RT target.  To make the system easier to maintain in the future, I would like to be able to generate a DAQmx task programmatically to the *.ini file exported from MAX.  In this way, users don't know what my code does to recalibrate the sensors or manage new material; they only know how to use MAX and where to store the files in config on the target.

  Where are the task daqmx, channel, and scale information stored on an RT target?  I have been through the files on the target you are looking for something that contains my task data but have found nothing, while dropping a node of system property in a VI running on the target will give a correct list of the tasks that I set up.  (The project that contains the aforementioned VI has no tasks in it IE: I do not import into the project.)

  Is there a utility that runs on the RT target that can generate a task at the time of the *.ini files exported?

  Thank you

  Exahustive keyword search led me to an answer on the forums.  I'll post here a brief summary in case someone else uses the same key words I.

  1 export the MAX configuration file

  2. write a VI that uses tools in the system palette to load the configuration on the target in real time.

  3 profit.

  In my case, the VI I wrote to download the config DAQmx also generates the configuration files for the screw on the side host and target, so everyone knows what is called tasks.

• monitor thread on the system in real time

  I have a SMU-8101 controller in my PXI system. I have it running with a system of operating in real time. I inherited some software WHICH has been used on a program of LabWindows used on a PC with a Windows 7 operating system. The SOFTWARE seems to work OK. My problem is when I leave the program I get an ERROR of EXECUTION NOT DEADLY

  "

  Source position thread ID unknown 0x000000EC

  Your CVI program ended on the target in real time. However, there still on the target in real time, the threads that are running or have already run the CVI code.

  Please check that your application cleans all its threads. Son left running after that your application can crash the target in real time when your application is unloaded.

  As I said I got the code and there is a lot of it. I am looking for a smart way to track down these threads. I was wondering if there are tools available that could help with this? Or any other suggestions on how to run these lines down?

  Hi DPearce,

  This article knowledge base has some information on why CmtDiscardThreadPool causes your program hang and gives some recommendations for fixing it.

• Programmatically determine if micro sd card encryption is enabled

  I create the code that needs to require that the micro sd card has encryption enabled on it.

  I so need programmatically determine that it is activated and if it is not my application must then leave.

  (1) is there a way to tell?

  It would be better if there was a way to tell which of the 3 types of encryption is enabled.

  (2) if it is not a way, so is there a way to make sure that the BES has set a strategy which tells the BlackBerry this micro sd card encryption must be activated?

  Thank you

  Unfortunately, there is no mechanism in place today to allow you to determine if the contents of the SD card is encrypted or you can determine if a policy is in place to force encryption of the SD card on the device.

  That said, the encryption on the SD card is intended to ensure the content of the SD card when removed from the unit.  The user would have full access to all content on the SD card and would be able to copy the files from the SD via USB Mass Storage without encryption.

  It is for this reason that we simply put in place encryption in the API itself (JSR-75) rather than expose APIs for what he.  If you consider your content to the need for additional security, I encourage you to encrypt the content yourself based on the Crypto API on the device.

• Programmatically determine the PCI device ID

  Hello again all you lovers forum useful!

  I am writing an application for exit to and read entry from ARINC PCI card, specifically the ICAN-530 of GE Intelligent Platforms.  Now their LabVIEW drivers and the documentation is pretty good, but one of the things that I have a problem with is how to determine the ID of the Board of Directors.

  The documentation on this Board ID is marked "for PCI devices, this Council number must match the device ID assigned when the installation of the API and the corresponding device has been installed."  I'm sure that I have discovered this using MAX, but what I really want is to determine if the laptop running my application has this card special in it ARINC and if so what is its device ID, by any program without the user to select or install MAX, etc.

  I hope it's doable, but I failed to find the right screw looking through this forum and in the pallets of LabVIEW.  If someone could point me in the right direction (or definitely state that it can be done programmatically), I would be very grateful.  :-)

  Thanks in advance!

  -Joe

  Just in case where someone else finds this useful thread in the future, I got the following response from GE Intelligent Platforms (who I bought the card), that indicates there will be a relatively simple way to reach my goal by using the LabVIEW drivers.  I have not tried so I can't guarantee its effectiveness, but it sounds good.  :-)

  If the only GE avionics installed is the ICAN-530, he would have no problem invoking AR_Board_Init until you encounter a status of passage; However, if there are other cards installed AND the distribution of the CIS - x 30 - SW is installed on this host, there is a mechanism to check room types.

  The AR_Query_Device of VI VI provided in CIS - LV Version 4.10 (latest version and probably the one would have received you if purchased with the ICAN-530), can be used in the following sequence to check such allocation device number on your system without actually opening a session and during the initialization of the Council.

  (1) call AR_LoadDLL.vi with the set control system Type to be 'CIS - x 30'.

  (2) call AR_Query_Device.vi in a loop (BoardIDIn control incrementing from 0 to 15) until the indicator of Type of card is returned in 26 (type for ICAN-530) AND the errorOut.code '1 '.  The BoardIDOut indicator will be the Deviceid for the ICAN-530.  Council for the VI types are described in the online documentation and printed for CIS - LV live.

  (3) If you will be running your application, you can just go forward on the basis of the VI AR_LoadSlv and waive AR_Board_Init (as AR_Board_Init is just a combination of AR_LoadDLL and AR_LoadSlv).

  (4) If you plan on using it to work with any other type of Council other than a CIS - x 30 Board, you must call AR_UnloadDll.vi to remove the library API CIS - x 30 memory.

  If you want the correct folder, the number of bit OS will not really help you. What to do if windows is installed to X:\Program files id... » ??

  Take a look at "get system directory". In particular, use the entry "application files. See if it meets your needs.
