Conspire in real-time

Hello

I'm working on a project of tension. I have read the data using the OPC. My variable is double wall to an address of mutual FUNDS. I want to plot these data to 10ms resolution. Is this possible?

I have download a code sample, I tried to solve this problem. but is is not accurate and does not.

You have an idea to plot the data in real time with a resolution of 10 ms?

Hi beginner,

you really need to redraw your project!

(1) not the OPC data source really provides new data with sampling frequencies of > 100 Hz?

(2) do you really need to draw the new data with a frequency of 100 Hz? You can't look at the graph that fast!

If 1) applies: make a separate loop to collect data at the necessary pace in a registry to offset (or any other method to store the data). If 1) does not apply: lower the rate to which you are trying to read new data!

(2) applies (no alternative): update your table with a rate of (say) 5 Hz. It's always fast enough when your field visualization and a lot less CPU consuming.

You need to separate the task of gathering data from the task of their display!

Your last question:

Any multitasking (standard) OS will involve a big Jig in your loop times. With a RT - OS this jitter is much smaller, but still different from zero. See the plug...

  • problem while conspiring waveform of the signal in real-time

    Dear Sir

    I use LabVIEW8.2 and USB1208FS for data acquisition. I have configured hardware with LabVIEW and data in real time using the Universal Library VI AInScBg.vi. When I draw my signal on the waveform (amplitude vs. frequency) then on axis x frequency ranges from 0 ~ 0.49 hz. I have change the sampling rate of 1000 Hz to 4000 Hz, but on the x-axis without frequency change occurs and it is set at 0.49 hz. Can you please guide me how can I get the frequency of my own interest on the x-axis.

    I enclose you daughter of LabVIEW for reference.

    Simply change the text label of the x-axis of frequency does not automatically the correct calculation. You do not pass in the sample information in the service spectrum, so you get no frequency information. You can see the strain on the entry point. The function expects a data type of waveform as input. Without it, the dt will default to 1. Then, use the function create a waveform and add information from dt to it as well as your table of Y.

  • Get strange errors 'real time' in the browser console, what do mean?

    I noticed recently that since yesterday is the day prior to that, I get a strange 'real-time' error messages in my browser console log. I get them for more or less the same sites, and I have attached a screenshot of some of the most common mistakes for example. I see these errors very frequently in the browser console log.

    Hello

    Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • Click the menu button

      click Help

      then select restart with disabled modules.

    If Firefox does not work, you can start Firefox in Mode safe as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac: Hold the option key during the startup of Firefox.
    • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
      (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. This might help others with the same problem.

  • Satellite Pro M30 - real time clock shows wrong time

    Hello!

    most of the time I am using my Toshiba satellite pro m30 without the battery with the energy of the power system. the battery is stored somewhere outside of the computer for a month the real time clock shows a bad time if the computer is started after a period of time.

    I think my cmos battery is going to die soon.

    someone has an idea, how this cmos battery can be changed by myself?

    Thank you
    Reinhard

    Hello Reinhard

    I agree with you. It is time to replace the CMOS battery. It is not easy and the machine must be dismantled. If you are not familiar with the procedure for disassembly, it can be dangerous. A small mistake can result with damaging material.

    If you want to do it alone, you do so at your own risk. Be sure to use the right battery. Maybe you won't believe, but if you use a battery hurt it could cause battery explosion, or other damage.

    I'm not 100% sure, but the RTC battery must be placed on the left side near the touch pad. If you want to only please be very gently. The laptop parts are very sensitive.

    Hello!

    Unfortunately, this feature is only available with the GoPro cameras.

    And Yes, if all cables already existing for these purposes, it would be kind of a pain to take pictures and do not shake the camera accidentally. Maybe, VSCO camera makers will make such feature in some time in the future. This idea is excellent and innovative. Maybe even Apple will listen to users and make their new iOS 10.

  • Debugging on a real-time target - deployment issues

    Dear community,

    After RT my 9651 sbRIO module wiring code, I do tests to check the intended functionality. For this I start my main VI who deploys the code on my SoM and I can happily move forward with my debugging session.

    Sometimes, however, while in the process of deployment, I get an error saying:

    [VI - name] .vi loaded with errors on the target and was closed

    When I open the VI it has no errors and the VI should work a fine might think.

    My solution was so far of the VI, just open move the wires and terminals round, re - save the VI and this is the deployment works.

    This trick worked for a while, because deployment error ca occur arbitrarily on different VI making debugging quite cumbersome.

    I then went ahead and just run the wrong VI in RT mode by moving terminals and structures around to get the VI runs in mode debugging, but it is very time consuming.

    Given that 3 people working on this project and we use git-subversioning I also do not want to "touch" each time just screws for the debugging session will without actually modifying the feature.

    Has anyone encountered a similar experience or perhaps found a magical setting to avoid this subject a lot of time?

    If solutions already present Spex does not do the trick for you, clearing the cache of the compiled object can help.

  • Real-time execution trace toolkit to optimize the Labwindows/CVI code

    Hello

    I am trying to optimize a code in real-time in LabWindows/CVI by minimizing the time of each section of the code is taking and find bottlenecks in the code. I check this time using the real-time execution trace toolkit.

    However, I just found it seems to be a constant error when you use the tool of real-time execution trace.

    When I put the traceviewer 'start' and 'stop' right after the other, I get around shift schedule 9us. It seems that the CPU will in some "idle" after the start of the trace mode, or maybe it's the time of communication or something.

    I'd appreciate it if someone could give me an idea of why this is happening. The time of real-time application window is very limited and I'm trying to minimize the time as much as possible. Even the United States 9 error is difficult to resell.

    I used the following code:

    TraceConfigure (1, 1, 0, 25000, NULL);
    TraceStart ();
    TraceStopAndSend (HOST_ADDRESS);

    and there is a photo in the toolkit of real-time execution trace.

    Thank you.

    Generally, you might be better off picking off the clock at the beginning and end of what you want to track. RTETT my introduce overhead that becomes difficult to quantify... Which is what you probably already see. The debug mode will also implement a ton of overhead. Then... Destemming of the clock in release mode will probably give you you the best estimate.

  • OR PCI-5640R serving of real-time Spectrum Analyzer

    Hello r,.

    Since you have not mentioned I guess that you do not have NI 5600. Therefore, to make this example work, you will need NEITHER 5600 buck frequency converter and driver of DAMA. NEITHER 5640R serves only as a digitizer in this case.  Also note that the 5600 is the resource name hardcoded in the program, so if you have OR 5600, you can either rename in 5600 Max or change the name of the resource in code for matching a max. You also need re 5600 NOR as a DAA, so so right click on 5600 OR in select Properties MAX and select external under scanner. All should be good as long as you recomplie the project to create a new file of ILO.

    Thank you

    I don't know another software in the software other than what is currently installed real time Wizard.

    Software shown MAX:

    Any help is appreciated!

    Thank you.

    Wow, Fieldpoint 6.0.1 was released in 2008 - which has been in the LabVIEW 8.5.1 / 8.6 times.  If you want to use LabVIEW 2010RT, you really need to upgrade.

    Try to download and use Fieldpoint 6.0.11: http://joule.ni.com/nidu/cds/view/p/id/3073/lang/en

    LabVIEW Real-time is not "natively" delivered with Fieldpoint or cRIO supported, these happened as part of the RIO or Fieldpoint support modules (so that the most recent versions of RIO or Fieldpoint update your support).

    Who give a shot!

  • The PSC-2000 is programmable with LabVIEW 2010 SP1 / Real Time 10.0.1?

  • "Support for LabVIEW Real-time 8.5.1 and earlier" and "Support for Windows Vista and earlier versions.  It means that I can not use the latest version of LabVIEW (2010 SP1) with time real (version 10.0.1) running on a Windows 7 computer?  If not, what version of LabVIEW, real-time and operating system do I need?
  • When I tried to add a new target under LabVIEW 2010 SP1, the PSC-2000 was not among the choices.

    As the support NOR documents indicate, you need LV version 8.5.1 or earlier to program the cFP-20xx devices family.  Version 8.5.1 of LabVIEW does not work under Win7.  You will need Windows Vista or something earlier like XP.
