How to get the timestamp of data DAQmx Read

Hello

I have to read 4 analog channels using DAQmx AI read in LabVIEW 2012. I am using screws DAQmx.

Acquisition rate is 4000 samples per second, and the number of samples per channel is 200.

I use only one task DAQmx to read the data. I get 4 data tables for 4 channels each table length is 200, every time, DAQmx Read happens.

But I want to get the seal of these 200 samples per channel. How to get the seal of these samples, made me know.

Thank you

You have not indicated your code. If you choose to read the waveform data, the cluster includes t0 and dt. That's all the information you need.

    Date1 - date2 is the exact number of days is after date2 date1. (It is as accurate as possible, given that the DATEs do not have fractions of a second).

    and one entire display i mean positive integer
    Select round ((sysdate) - to_date (date_start)), date_start days of per_periods_of_service

    You want to probably get the exact number of days first, then ROUND this number:

    SELECT  ROUND (SYSDATE - TO_DATE (date_start, ...))   AS days
    FROM    per_periods_of_service; 
    

    Always pass arguments at least 2 to TO_DATE:
    (1) the string to be converted, and
    (2) a saying string how (1) is formatted

    This gives negative also result

    Right; If date1 is before date2 then date1 - date2 returns a negative number.
    If you want to never get a negative value, use ABS (date2 - date1). If it returns 4, then you know that one of the DATEs was 4 days before the other, but you won't know who was earlier.

    I hope that answers your question.

  • How to get the timestamp to start at zero hours?

    Hello.

    I build software that records the values to Excel.

    The user can specify how long the test should run for, and the elapsed time should be defined as a string in hh: mm [:]

    The only problem is that the timestamp begins at 01:00 (calibrated 1904-number I guess). How can I get the count from 00:00:00, or perhaps to subtract the time at the beginning then it starts at zero.

    If you run the VI, you will understand what I mean.

  • How to get the timestamp to install official application?

    Is it possible to get the runtime the timestamp to install official application or datetime?
    I not looking for third-party solutions or workaround, but just the bb: official package.

    It seems that it's not accessible, I looked at those:
    BB::application
    BB::Cascades:application
    BB::ApplicationInfo
    BB: PackageInfo

    And none has the information you're looking for.

    Of course, it is quite easy to do it yourself with QSettings:

    settings.setValue ("installDate", QDateTime::currentDateTime());)

    Hello

    I guess you have a binding method as the first activity in your stubborn workflow. Open your workflow in preview mode, right-click on your connection method and say «Go to the PageDef» This will create a definition file page for the binding of your method. You can use this to put the iterator binding that you want to access from your init method.

  • How to get the "Sign" option to display; Reader XI on Win 7

    Lately I am unable to get the option "Sign" to view the XI player.

    Reader XI, Win 7.

    I found this statement but could not do this job:

    If the icon of the sign is not in the toolbar, right-click the toolbar, and then choose file > Add text or Signature.

    I have a right-click just to the left of the "Tools" command, but the file > showed an option to "Add Signature text.  What is displayed for file > 'Documents', 'convert', 'create a PDF file", etc.  Not sure I'm in the right place.

    The document being interest is one that I scanned.  I checked the properties of the Document, and it says "filling of form fields: permit."

    This feature of 'Sign' existed before, and I don't know what has changed.

    Help.
