Control of data rows Excel (write on a file of measure)

Hi all

Objective:

Get a bit of a live waveform of two pressure sensors, as well as calculate the differential pressure. The LabVIEW VI is intended for students for an exercise in module, in which data are exported to an excel file for the students to perform other calculations. Excel file must contain data from the beginning to the end of a race.

Problem:

Pressure sensors work well, waveform table works well, but when you stop the collection of data, the amount of lines in the file Excel output will reflect the number of samples per channel of the DAQmx Read Block (10 = 10 rows of data, 100 = 100 lines, etc.).

I would appreciate some advice on how to conduct the data collection in the part worksheet from start to finish, without this affecting the aesthetic experience of the student (by that I mean the number of channels of the > 10 sample will cause some lag in the waveform, jerky). I tried to resolve this issue with something in the sense of Tank1Solution.png without success. I've included a photo of the original block (Tank2Block.png) and so I worked the file VI.  Once more, any help would be much appreciated, I'm not well versed in LabVIEW and I do not know how to address this problem effectively.

Some guys are always doing things the hard way

Of course, you need a son to ai0 - ai2 and ai1 - ai9.  This linear scale DAQmx is of course very convenient! and hey, the TDMS files import beautifully into Excel! the addon is there then why not just open a session data?  TDMS is much more portable than xlsx.

A few additional remarks. (a) you can't stop this vi before you press Go-who needs a fix. (b) Create scale is likely to return an error as it is the name being illegal. I named it that to show the source of the scale and offset values.

  • filtering of the data sent to write to the file of measure

    Hi everyone, I was wondering how to implement a "filter" that prevents the data to write in the function "write into file measuments.  Say if the incoming data is a 0 (DBL), hwo to prevent it from being written?

    Use a box structure.  Put your writing to the file of the measure within a case structure, probably in the REAL case.

  • Write to the file of measurement with a loop For using the value of the dynamic data attributes

    I looked and looked, but couldn't find a solution for this.

    I currently have 15 points of different data that I try to write in an Excel file.  I have all combined in a table and lie with the function "write into a file position.  However, the column names are always "Untitled", "Untitled 1" etc.  I then used the function 'Set the Dynamic Data attributes'; but for this I have to do 15 different functions "set data dynamic attributes.  It was suggested to use a loop with the function 'Set the Dynamic Data attributes' inside of her, but I can't find how do.

    I have several arrays consisting of 15 different values for 'Signal Index' 'Name of Signal' and 'Unit', but also a unique 'get Date/Time In Seconds' related to 'Timestamp '.  The problem is that the error I get when I try to connect the output with Scripture at the entrance to measure file:

    The source type is dynamic data table 1 d.  The type of sink is Dynamic Data.

    How can I fix it?  I have attached a picture of my installation; Sorry if this is gross (I'm new on this!).  Thank you!

    It will get rid of the error, but it is not quite correct. What you need to do after that is to click on the output or the tunnel entry and select 'replace with the shift register. In addition, the array of values that you have wired to the Signal Index is wrong. Arrays are 0 based. Just wire the iteration Terminal here. And, finally, take the size of the table and this connection to the N terminal are stupid. Don't wire nothing to this.

    I'm writing a file format xlxs using writing to express vi measure, every time I have applied no file has not been created

    You try to deploy the express vi into your RT controller? You should try using the low level screw and you can use the shared variable to transfer the data to the host. The method that you try may work only when you have the card in your PC. Also, you will get only the latest data saved to your file as you write the last item coming out of the execution of the loop. Try to restructure your code and check examples of LabVIEW.

  • Write to the file of measure seconds (10)

    Hello everyone, if you display the VI attached, you can see that I'm running my average in a .tdm file. That's fine, but I want to document the average all ten or so seconds, instead of dry chaque.25 that she is currently recording. Any suggestions? As side note... is possible to stop the .tdm file to have stuff all that extra (Group, channels, description, wf_ *, etc.)?


  • Write to the file of accounts, data from customs (intersection POV) in the rules of HFM

    Hi all

    I'm trying to use scripture to deposit into the HFM rules. I am able to get the entity, scenario, year, time, and Timestamp to save to a file (see code below). Is it possible I can get accounts, customs and crossing of data also to write to a file and make the analysis of perfromance? Basically, how can I have the whole POV in a log file and test the rules.

    f.WriteLine txtStringToWrite & '-for:-"& HS. Entity.Member & "-" & HS. Scenario.Member & "-" & HS. Year.Member & "-" & HS. Period.Member & "" & Now()

    Thanks in advance. Looking forward to hear from you.

    Chavigny.

    The account, PKI and custom dimensions are not part of the point of view that the entity, period, year, scenario and value. The only way that you can write these dimensions in a file is to call them in a table, as HS. OpenDataUnit, or list any. It is the only way to get the context for intersections.

    If you try to write data to a file, you'll end up with a file that is at least as large as the database itself and could be a very slow process. If that is your intention, you would be better to simply analyze the database. Write to a file should be used only for debugging.

    It is the way it works. Note that the link layer refers to the data control by its ID not physical class name.

  • Read or write data in excel

    Hello

    I wanted to know if it is possible to read or write data in excel programmatically? And if possible how to do this?

    I searched a lot on this subject. All forums say how Sung some software. What I wanted to do is, I want to create an application in which I might be able to write data to excel and also read data from excel. Specifically, I can do Java using some jxl. Is there something similar to that?

    Please help me on this since it is a very urgent need for my client.

    Thanks in advance.

    There is no API to write files to Excel on the BB, and I think you will find that this jxl use J2SE functionality that is not supported on the BB, it will be difficult for this port.

    If you plan to be able to put an Excel worksheet on the SD card on the BlackBerry and directly using these data, there still, sorry this is not supported.

    I would investigate export Excel data to SQL and then using SQL on the BlackBerry.

  • How to save data to excel, word, etc.

    I want to use the entry in the spreadsheet, but the format of the saved data cannot be opened directly in excel or word. Can I still use write on the worksheet or that I have to use other buttons. In fact, I don't know how to choose the format of the recorded data. Thanks for responding.

    ADrexelDragon wrote:

    The format of the Vi called write in spreadsheet records directly in a xls file.

    Not exactly. It stores data in an ASCII ' Tab/return' file (assuming that you do not change the separator). Means that the file can be opened by any text editor. Including Word and Excel.

    If you want to open the file directly with Excel (or Word) with a simple double click, then simply add .xls (or .doc) as the file name extension.

    If you use the .txt extension, there are chances that your case will be opened by Notepad.

    Nothing complicated!

  • Speed up the transfer of data from Excel

    Hey!

    In my VI, I need the contents of 3 Excel files. The VI then takes in the filter criteria and uses them to filter all the data and produce graphs. Problem is that all 3 Excel files are more than 8000 lines deep and wide of 40 columns. She takes super long to get the data from one of these worksheets, nevermind 3.

    IM only starting this project, so I wanted to find the best way to address the issue.

    Is it possible to quickly transfer all the data from Excel to LabVIEW?

    If I read once and then writes it to a binary file for quick access, which would be better?

    First create an Excel CSV file - open Excel, choose delimited for save as type CSV comma and the name of the file to anything you want.

    It might be easier to suggest how to export data in high file if we could see your VI. You can follow the following steps to get two columns of data in Excel exported from labview.

    (1) create table to 2 dimensions for your y and x values by using the array build function.

    (2) wire the output of the array build at the entrance of meashrement vi writing 2d data. Thread at the entrance to the path to the CSV created as shown above.

    (3) wire the constant true to add to the entry of the file to write to measure vi.

    (4) make sure that it is not a broken arrow to run arrow and code is complete and all the required inputs are connected properly.

    She's. Run the vi that data should be exported to csv file that you created previously.
