Export waveforms to the worksheet File.vi

Hi all

I try to use the waveform to export as a spreadsheet on a waveform that is added for the duration of a while loop with a registry to offset. The VI works fine and acquires all the appropriate data and the corresponding points however when I hit the stop button to exit the while loop is not fast or pop up asking me to save the excel file. The VI ends just after leaving the while loop.

Nothing else has this problem? I think that I am likely missing a step somewhere, but I based the block diagram of a video presentation to youtube (https://www.youtube.com/watch?v=GBhJk5Tnshc) and I can't seem to find my mistake.

Please find attached my diagram and the VI and apologies for the link text above, I'm not sure on the exact validation protocol here.

Any help would be appreciated!

Hi ofis.

you alluded to run your VI on a target of myRIO!

RIO platform usually has NO attached screen to display a UI to the user. When there is no interface user you cannot display a file on/in the user interface dialog box.

Just provide a constant filepath to the VI WriteWaveform - and don't forget to choose a path is available on the target of myRIO: you can not record directly on the hard disk of your PC!

On your VI:

Why are you warking with a waveform at all? I don't see any setting of rates specimen, so a waveform of construction seems foolish to me! Simply collect your data in a table and use the simple SaveSpreadsheetFile function to save this table on disk (myRIO)!

  • How to remove header, time and date of the Subvi "export waveforms to the spreadsheet file?

    I use 'Export waveforms for spreadsheet File.vi' in order to export the labview data into a file.

    However, the default format is the following:

  • When I export to HTML, the HTML file is not displayed

    Hi all

    I have a template that I modified. I've been recording and when I go to export it to HTML format, I can't find the HTML files. There are files CSS, image files, but not the HTML files.

    Is someone can you please tell me where I have gone wrong? I need to be able to export as HTML in order to show my boss files and send him everything so that he can see his computer via a browser without having to host them.

    Repeat the file > export as HTML in an empty folder.

    If you have manually deleted a file that was previously exported .html files to, Muse will think that they are still there and not re - export (assuming that you does not also remove the file muse_manifest.xml, where Muse keeps track of what is exported).

    Regardless, exporting to an empty folder will cause Muse of re - export all.

    How about if you uncheck use of bleeding doc and manually enter?

  • Problem with 'Write to the worksheet File.vi' in Labview 8.2

    Hello

    I wrote a vi to reduce the noise of my source of signal (voltage). When I wrote in the spreadsheet file, it saved only 10 rows of data. How can I continue to record the signal until I stop the vi.

    Thanks in advance,

    Michael

    How many samples you take with the DAQ Assistant? Is it ten?

    Please pay attention to the answers. You never want to save more than one iteration until correct you the entry in the spreadsheet file.

    Post your VI if you still have questions after the fixing of the VI.

  • error of cFP-2020 by using entry to the worksheet File.vi

    System: cFP-2220 running LabVIEW 8.5

    We are using Scripture in the File.vi worksheet to record data to our PSC and get a very strange error.  It will not accept the name of the file and gives us and error that the file name is empty or a parent.  The name of the file is built as "YYYY-MM-FichierJournal.txt" and the actual value is "c:\2010-01_LogFile.txt".  Thus, it is not relative and the correct name is fed to the vi.  This vi is polymorphic and I use DBL 2D data.  I changed the text data, but it did not help.  In addition, I changed the name of file/path to "c:\1.txt" where it was a matter of length of file name. Nothing has worked.

    All the suggestions and help is greatly appreciated...

    Hi FilterGeek

    Your PSC-2020 and your cFP-2220 run a different operating system.  The cFP-2020 is to use Phar Lap and the cFP-2220 uses VxWorks.

    The two operating system use different path conventions.  Your specific question is explained here.

    Please let me know if you have any problems of implementation of the workaround that is listed in the article.

  • Simulation read data file (*.) (DAT) by using the worksheet (file reading eror - zeros)

    Dear OR community,

    IM pretty new in LabVIEW, so I have a few broblems with reading the data.

    I take a screenshot and mark a problem like part - A and part b below:

    The description of the goal:

    I do a mathematical simulation, using the old software whitch exporting results as shown in 1... DAT file, as it shown in the picture (Notepad).

    First of all I need not read these data then I need to draw the graph XY.

    Description of the problem:

    I created a LabVIEW program and im using a funciont reading of spreadsheet per section B - but when im trying to read data im getting all zeros...

    so I can't identify my problem... What is the problem?

    I try different file to read its Case_test_working.txt and everything is good with this data but when im trying to read *. DAT file zeros is array...

    I tried to use seperator different symbols, also try to imort data to exel then export to *.scv, *.txt formats, but the performance was the same as that indicated in part-A.

    Whenever I get zeros, but not a results as in *. DAT or another file format exported with the same data.

    Please be respectifull and understand that im still newbie in labview but I think its excellent software of filtering of the analysis of data and calculations, so I want to master this software for my future use.

  • scenartist closed captions export results in the empty file of CCS

    I imported my legends like MRS. When I export via the menu media export I get:

    so no subtitles in it (it takes about 500 of them!).

    If I export in other formats such as stl spruce, it works.

  • How to cut a clip and export using the same file format

    I use CS6 on a Windows 7 system. I have a MB 304, 8 HR record from a workshop that I put on recently and I would like to extract the different sections of the workshop in their own files.

    Here's the info from the source file:

    Type: MPEG Movie

    File size: 304,0 MB

    Image size: 1920 x 1080

    Frame rate: 5.00

    Audio Format: 16000 Hz - compressed - Mono

    Project Audio Format: 32000 Hz - 32 bit floating point - Mono

    Total duration: 07; 35; 20; 25

    Pixel format: 1.0

    My ideal solution is to delimit work areas that cover the section I want to extract and then export it to the target file by using the same parameters as the source file.

    So far, the resulting files have been considerably larger than the source file, so I hope that there is a simple way that I'm missing.

    THX!

    So, can you go down to set rates manually? It's been a while since I used CS6, but I think that the option was there... and something you can do to help, is to say MediaInfo on your computer...

    Media Info: https://mediaarea.net/en/MediaInfo

    Drag & drop your clip on that, it will tell you the exact wrapper and the codec used, including the bitrates & such. You will know exactly what your current clip is this way. Build a preset to match.

  • reading of the worksheet does not all columns

    Dear users and moderator.

    I'm trying out a text delimited by tabs of the data file. I would like to transfer the data in a table 2D with VI 'Read the worksheet file', but it seems that only the first column is acquired.

    I checked and the delimiter is fine. I also tried to change the format, but without effect.

    Does anyone have an idea about the problem?

    Thank you very much and good luck.

    Andrea

    You must put the tab delimiter character correctly. Right-click on the delimiter string constant code and select display.  It will show \\t.  Remove one of the backslashes. Otherwise, simply replace it with the character of tab delimiter string.

  • Is there a way to export / print to a pdf file which is flat? That is like printing on paper and a new analysis?

    Is it possible (if not, there should be MAOIs) export / print to a pdf file which is flat? That is like printing on paper and a new analysis? (I do not want to use this last)

    I could list 100 reasons why it would be useful to be able to do this, then please none of the usual "why would you do that?' or ' is not the right way... blah blah blah" which is too often here.

    If you are Windows on a machine, you can print the file to the Adobe PDF printer, thus creating a new copy of it.

    If you want to convert the entire file of images, then you can export it to the image files (PNG, for example) and then create a new PDF from that.

    If you want to flatten the dynamic objects (such as form, comments, links, etc.) then you can use a simple script to do.

    There are many ways, your request may be interpreted... If you provide information on what you are trying to achieve it will be easier to help you do.
