indicate the end of the loop to the Subvi state information user

I hope that I can adequately describe this as an example would take time.

I have a test that implements a chip by using a scheme of control in series. This takes place in a Subvi. When the control bits that all entered the chip, a flag is asserted. I want this indicator to display on the front of the parent company of VI. The parent VI runs the Subvi iteratively until all the test cases are covered. A user dialog box interrupts this main loop to give time for the user to physically move a probe. I would like to indicate to the user that the test conducted in the Subvi is over and he can move the probe to the next test point.

If I do a link with the flag in the Sub - VI the indicator on the main façade follows the status of the indicator in the Subvi through the first iteration, but then stays like that, even if the flag is disabled in the Subvi at the beginning of the iteration.

How can I get an indicator in the main VI to display the status of the indicator in the Subvi?

As Dennis said, it's a matter of data flow.  The Boolean value is passed out of the Subvi that once completed the Subvi.  At this point, your GUI indicator is defined with the value coming from the Sub - VI.  What I suggest is to erase this GUI indicator just before running the Subvi.  I does not affect the Subvi at all, only the indicator is on your main façade.

    DDL is not available in PL/SQL. You do not normally run DDL in PL/SQL, but if it is justified, use you dynamic SQL:

    When I opened the window "save the Page under", the drop-down box file name indicates the files that have been saved a long time ago. It is not cleared by a function 'clear history' that I can find. How can I erase this?

    Hello.

    I think this is a related issue of Windows, because it is the Manager to save the windows file that we are talking about here (right?). You should contact Microsoft for help with this one, I think. You expect to be able to delete entries simply by touching delete on your keyboard when they are concentrated (that is how it goes for the removal of the form entries specific autocomplete in Firefox), but I have not tried.

  • Re: Satellite L555 11 L: BIOS indicates the drive HARD is not installed, BOOT Manager said HDD

    Hello!

    I had problems with my Toshiba laptop.

    When I tried to boot my system after a regular stop it does not recognize the HARD drive more.
    BIOS indicates the drive HARD is not installed, the said BOOT Disk Manager failed.

    Tried the HARD drive to a desktop computer and it works fine. This is not a new HDD SATA is recognized.
    However, the boot sequence itself and other functions seem to be ok.

    Who is wrong?
    The laptop is 1.5 years old and didn't have any problems before.

    Any help is appreciated ;)

    Hello

    It seems that the HARD drive is damaged.
    In your case the drive HARD test would be recommended.

    Download the software called Drive Fitness Test. It the free tool that can be used for the test of HARD drive.
    If the HARD drive is not detected or you will get errors, then it means that you HARD drive needs to be replaced and OS need to be installed again.

  • A generated within a loop in a subvi output data can be transferred to the main program for each iteration of the loop?

    Hi LV users,.

    I have a very basic question, I have not succeeded to asnwer using basic considerations.

    I made a sub - vi that performs a scan of current-voltage using a unit of measurement-source Keithley and a loop FOR.

    The subvi outputs 2 tables with my data (essentially an array of voltage and the corresponding current table). I also defined a Terminal at the exit of a group of these 2 tables in order to plot a graph XY - output. Specifically, I indexed this cluster to update after each iteration of the loop FOR, in my sub - vi (the indicator is placed outside the loop, of course).

    My problem is that I want my main program to display the XY-graph in real time, with an update after each iteration of the loop FOR which is in my sub - vi.

    I have a problem because my sub - vi output terminals are available for the main program concluded as soon as the sub - vi has completed its own execution (which is what we expect of sub - vi to do).

    How can I use a sub - vi (because it's handy) and get in the main program in the course of its performance data that are generated from the loops of sub - vi?

    Thanks in advance for your help,

    Yoyo87

    Elements of the queue in the Subvi them put your main VI where you want to display the data and the.

    It is similar to the architecture of producer/consumer. There are examples of it in LabVIEW. The examples work with 2 parallel loops, in your case a loop (the producer) will be in the Subvi.

  • graph of data from inside a loop of a Subvi from the mainVI

    Hi all

    I have a Subvi in one mainVI, among others. In my Subvi, I have a loop For 20 iterations and I acquire 2 signals at each iteration, which I draw in a XY Chart.

    What I want to achieve is to visualize two signals above in the mainVI at each iteration the Subvi and not when it is finished. Is this feasible?

    Then I set a very simplified example of this case. I can also attach a copy of my specific VI but there are a lot of sub - VI is there.

    I'd appreciate any help!

    Best,

    Dimitris

    Hi Dimitris,

    Thanks for the post and I hope that your well today.

    You can do this by using a reference to the chart of the main VI, pass it to the Subvi vi and use a property node to update the value of graphs.

    I have attached a modification of your code to show this, labVIEW 8.6.

  • How a detector of fuel level on the USB/serial port to indicate the level of the interface?

    Hello!
    Im working on a project that contains a fuel level (capacitive sensor) sensor. My task is to connect the sensor to a PC and indicate the level of fuel on a chart. The instrument works with 1-wire communication, but Ive built a USB converter for it. So I want to plug it into the USB port on the computer and use Labview to access the fuel level. Its important, I need indicate level constantly, because the probe will build in a bus to see his level of fuel. I've never used instrument in LV control, that is why now wrote im.

    Please can someone help me build a VI to do this?

    Thank you very much
    Regarding.

    When Outlook Express 6 detects emails from a name in the right column indicates the folder in which it is in. How can you tell which folder this folder is located in?

    OE does not have the capacity to tell you where the folder is located in the folder hierarchy.  You can select different trees under local folders to find what subfolder is and what kind of tree it is under.  Unless folders.dbx is corrupted (which happens a bit), then OE will not create folders for you.  If folders.dbx is corrupt or not, I would suggest that you backup the files and the registry (see www.oehelp.com/OETips.aspx#6) before things become corrupt, because you seem to have a complex organization from your e-mail folders.
