How to record measured analog data on the PC?

Hello

I am a beginner in the real-time hardware. I have the cRIO-9024 controller and the cRIO-9112 chassis. I have a few questions:

(1) I can't see the examples because Labview 2009 shows that The NI Service Locator is not running. I just installed Labview 2009. How can I solve it?

(2) what is the best way to filter the measured analog data? There are hardware module filtering or I have to use Labview tools as filters pint? I would like to read data to the time step 1 Ms.

(3) how can I save measured analog data on the PC? I tried to use 'write to file measured', but he did my program slower and I couldn't get my 1 mS of a cycle. Can I use cRIO-9024 memory somehow and after when the programme is complete to save the files to the hard drive? Maybe it would be faster?

Thanks for any help and examples, whether it would be possible.

Hello Rodzynek,

If you do not have the FPGA module (or just for now) the solution you gave with the filter would be OK. Place a second loop for file IO (and possible your communication to the user Windows interface) would be a good idea. Do not forget that you are using on the function of file create the file path represents the drive of the controller cRIO (which is mostly a c drive). You can send via FTP to the RIO DC (using the IP address) and have a look at the files.

A suggestion to get this file programattically is that the cRIO controller sends the file name of the Windows user interface (after the closing of the record), with the Windows user interface, you can use the FTP functions in Labview to get the measures file.

Best regards

  • How to access a certain date in the date and time field SQL Server

    I have a field named job_date in a table in my database of the 8 SQL Server.

    The data type is datetime.

    Thus, the values for the fields as the 2013-03-11 15:55:52.000 look.

    How to query this field to include only the values of a certain date?

    For example

    < / cfquery >

    When I query the field now I get NO RECORDS.

    This is because as the fields like this 15:55:52.000 2013-03-11. instead of this March 12, 2013"

  • How to record entries of UI with the data measured in a TDM file?

    Hello

    I built a user interface to monitor and control a pump test bench, I use the USB-6212 in a Windows PC with the new SW and readers.

    Now I try to collect all the measured data and control values in the UI, permanently at 1 kHz and write it in a single file of CT.

    The problem is that only the measured signals get connected, but only a few values at the beginning of the file are saved in the user interface; then all empty.

    I have all tried, producing waveforms, synchronize them with measured data for the same stamps, aling & resample and blocks of collector of the Toolbox Signal Express, but there are still some missing data in the user interface.

    In my original configuration, indicated in the post, I set up the block of analog to read continuously at 1 kHz with 100 samples, while output and analog digital on-demand writing. I have included the file complete, just in case some block causes disruption.

    Your express DAQ screws will probably be reading/writing of multiple samples for each run, then wire you a single value for your set points. The use of the data type of dynamic signals hides this information from you (that's why nobody is using them once they become more familiar with LabVIEW).

    You need to take only the last value of dynamic data, or touch your set points so they are the same size as your dynamic data. If you write 100 samples at a time, then you will have your set points only once by 100 values. You must create a table/waveform of 100 points with the same value.

  • acquisition and recording of analog data with producer consumer model

    Someone on this forum, in a separate last week discussion, suggested that I use the producer model consumer data acq.  My ultimate goal is to acquire analog channels 1-4 continuous data, display graphical band style and save the data on the boot disk when the user presses the 'Start Saving' button (and will continue to display recorder cards).  Economy will stop when the user presses the button "Stop Saving" but strip map will continue to operate.

    My attempt to use the producer-consumer model is attached (LV 8.5 only).  It does not work.  I have not tried to implement for recording user controls - just trying to make simple continuous display and save (1 channel) at this stage, using this model.  VI runs, but the graphic Strip is never updated with the actual data, and the data file that is saved has zero byte inside.

    Thank you.

    WCR,

    Looked at your code, and you are right.  It won't work.

    Take a look at this example:

    http://decibel.NI.com/content/docs/doc-2431

    The VI of the acquisition must be inserted in the loop of the producer.  In addition, you must tell him how many samples for (otherwise, it will get 0).

  • How do MANUALLY enter you data into the application of health 10 IOS? There is no symbol and touch edit only gives you the option to delete existing data.

    I checked in the application of the health and read the Apple support page. They show the screen for 10 IOS on an iPhone, but their instructions don't work. There is not a Plus symbol to add data manually. It has only an editing tool that you can touch and only allows you to delete data.

    Hi, rmetzker!

    To manually enter the data points in the application of health, first go to the display of data on health as shown below.

    Then select category to which you want to enter data in (I'll use body measurements for example), then press on what data you enter (measurements > weight). In the upper right corner, it will be a plus + icon for you to manually enter your own data points.

    I hope this helps!

  • How to remove documents and data in the iphone app podcast 6

    I know how to remove each podcast, but how do I remove "documents and data" in the application of podcast?  I have more than 4 GB of data and documents.

    I think I found a thread that is useful for you: https://origin-discussions-us.apple.com/thread/6822791?start=60 & tstart = 0

    Sonny3301 answer worked for me, «...» "(The steps are: 1) download the Battery Doctor app on your iPhone (it's the first one that appears in the search) (2) hit the"Junk"icon on the bottom and tap 'Clear Cache'." (3) repeat until your space becomes available. The people that I learned this technique of some other bulletin board said it took 10-15 tries; It took me + 30 attempts. The memory savings start small at first, then it starts to hit hundreds of MB at a time. It sounds crazy, I know, but I went to have less than 200 MB of free space for 3.6 GB. Great thing, it was my podcast app had only been hogging to 1 GB of data, so the app battery doctor found 2.6 Go elsewhere. Good luck to you all and you are welcome. »

  • How to connect an expiration date in the ID and the password set cached?

    I have windows 2003 race. I would like to know if there is any kind of code and where it must be added have log vpn users in the local network before they user of the laptop to go on the web?

    In other words, how I plug in and the expiration date for the caching of id and password?

    I'm not sure that's what you want.  You can change your machine such as passwords are cached at all, but then a person could not connect to his laptop unless it is connected to your domain, when it connects (forget not to use your computer on a plane).  If you want to control access to the internet, many businesses use a Proxy Server with a password to regulate the internet connection.  See if these MS articles shall apply:

  • How to record what is happening by the sound card without using the microphone to avoid loss of quality.

    I tried, but there is no "Stereo mix" available options. There is only the (Conexant High Definition Audio) Microphone. It did not work. What I'll do is to buy a DVD for TV (tv Record program) burner and plug the hdmi cable from my computer to the DVD recorder and record what I want. After that, I just rip the audio from the file. I see no other option to do. I use windows vista Home premium.

    I would like to know how I can record the sound that is played by the soundcard using Vista without using the microphone as a source. Let's say the audio is played (audio stream) and I want to record this stream. There are many software that we can download that record what is happening in the microphone. The sound bounces off the speakers to the microphone. But when this happens, you lose a lot of the quality of the audio. So my question is if it is possible to record what is happening to the right of the sound card, before being sent to the sound card in order to avoid the loss of audio quality.

    ==============================
    Movie Maker has an option to record Narration...
    (Tools / tell the chronology). If you select stereo mix
    as the "Audio Input Source", you can save the
    Audio online. Your speakers and microphone are
    not required.
