Write to measure file by default to 'save to a file.

I am using the 'write to Measurment queue' to do a series of files - but as soon as I hit ok it is default to 'save to a file. Even without running the VI he defines simply himself back. I have attached files what it looks like before you hit OK, the settings, and what happens when I close.

Maybe it's a bug?

Also, if you can see, I don't want the file to be called testdata__, but there is no way to change the prefix of the file because the area is grayed out. Any way to change this either?

What version of LabVIEW are you using?

LV2009 has a few bugs with writing custom file Express VI.

  • How to set a record time of a capture or write in measurement file

    Hello

    I worked on it for longer I should have without asking for help.

    I am tiring to save a capture 10 to 15 sec of my contact information to a write to a file of measures.

    The work of capture, but I have no idea how to attach a timer to stop capturing after 10 to 15 seconds.

    Ideals would help considerably.

    I have amp using labview 8.6 and a card entry with an entry of the SCB-68 interface PCI-6220.

    Hi Richard,

    I would like to make use of the express VI of elapsed time, the code might look like the attached VI.

  • write to measure file vi bug?

    Hello.

    Looks like I might not be the first with this.  I suspect...

    http://forums.NI.com/NI/board/message?board.ID=170&message.ID=234485&query.ID=1018110#M234485

    I still after that I don't know how many hours days etc., failed to do this work.   I had to go and do a 'real' job, as it is called here for a few days or so, don't play no not with the software, however, is that asked me to do.

    This is all about 'Writing as Data File' express VI comes with LV 2009.   Used as Cree in the document "Getting started with LabView" infamous.   Running on XP Pro, perfectly (until tomorrow "Patch Tuesday" maybe.)

    Writing on a data file Express VI:

    It works the first time, no mistake, a lot of data, the first time entry to activate is made true, even if I leave it is true, thankfully, it creates several KB of the planned just as data file.   Do activation enter False, writing to the file STOPS, again just as expected.

    New do right and produces an error (the chemin\nom of the input etc file is still there and equally valid that it has always been) and no data is written in the file, despite no changes to the inputs of the VI (with the exception of the data of unique signal value)

    However, if give you him a new one (same file path\new) file name, and then he would write in the new file every time.  It's without blocking the program as a whole.

    I can navigate between two files just fine.   But it just will not write to a file first, that it is "Re" active after a deactivation is used.  Re entering the same path\filename is not a solution.  It must be another to wake up the thing.

    As it is, it's worse that useless for any serious application, and as the other party, I can't imagine how he got through the mill of QA.   As the other party, it is sold on the fact that it is supposed to be easy to plant items/icons on the comic and join the dots to make things work.  While largely true and there are a lot of good stuff here, there are a lot of things that exist for travel upward and confuse him.   The help is too small.  I get the phone call and email to other types of NOR, but no solution to the problem.

    If you want a copy of the VI program all the so-called fine, just someone tell me what and how to download it on this forum (very strange).  I can upload images, but I can't find a way to "attach" files, etc.  Or to work through the Getting Started document (as I have now three times!) and you will find the problem.

    Oh, and I seem to have lost the indicator as to how much
    days of "evaluation" I left.  I can't find a switch to make it appear that
    Gray more splash screen.

    I think that there is certainly a bug.  I can see where it is going, but I don't know why he got that way.  This VI shows the bug in LV 8.6 also?

    Right click on the entry to measurement file Express VI.  Inside that is a Subvi, called ex_subFileWrite.vi.  It is a clone of a reentrant VI, so it is quite difficult to follow execution through it.

    Somehow the first time through she builds and checks the file name based on what comes into it.  She that stores into a shift register.  If you clear the writing to a file, the shift register is stored which is not a constant of path.  Later, when writing is reactivated, it uses just the path (not a path) from the shift register, rather than back in the name of the input file.

    Exactly where this is really out there, I'm not sure, because express VI makes such a spaghetti with inter twisted code for managing all types of files and in writing the conditions and a lot of manipulation of file file path.

    I think the reason that edit the path and even change back works is that there is an initial control if the path is the same and if it is different, it works with the new file name, if it isn't, then it works with what was stored in the shift register.

    A person of OR should look deeper into this substantive code of the Express VI and try debugging.  I think that there is a bug.

    But here's a work around.  Use a select statement to send the correct file name if the writing is enabled, or a file path empty if it is not enabled.

  • write the measurement file

    Hi all

    In fact, I'm writing a file of measures. I'll have a waveform from the oscilloscope and I want to record it after every 15 seconds.

    In the attached VI, I simulated signals (the driver that I use for data acquisition also got the while loop) and performed an analysis on it. As shown in the attached screenshot, I use the write action 1 file to connect the data as soon as starts the acquisition and then I use writing as filemarked 2 to get the data after every 15 seconds.

    I thought that this arrangement should work, but it does not work

    Could you please guide me in this regard? I want to write data to a file of measure for every 15 seconds.

    Looking forward to your response.

    Best regards

    Hernu

    The use of the timed loop is unjustified at all, IMHO. Simply place a time elapsed in the main loop function and it wire to an instruction box with the writing inside function. Or use an architecture of consumers/producers (file > open...).

    The way you wrote that the displayed example shows that you don't understand really LabVIEW and data flow. Always take the tutorials. ?

  • Added a timeout for a write to measure file operation?

    Hello

    I have a question that I think will produce a very simple and direct answer, but I do not know how to approach it.  I write data to a file of measures LabVIEW and am allowing writing custom Subvi file with a simple Boolean button (i.e. when we click the button data are saved and vice versa).  Instead of having to click the button a second time to stop recording data, I would like that it resets automatically after a certain period of time so that all my files end up being the same size and scale.  I'd like to think that all I have to do is use one of the time functions (functions-> programming-> Timing), but I don't know which.  Any help will be appreciated.

    Thank you

    That's where.  That's what the button labeled 'Save' does.  You just need your file write code in the structure of matter as well.

  • prompt user with write to measure file VI

    Hello

    I have a Labview VI who is writing data to a file, currently the file name (path) is written in the section "Filename" of writing on a file measure VI.
    Is it possible that a user can be prompetd for a file name?

    As in,.

    time each time I run the VI a diaglog box appears, which allows the user to type a specific file name (say Run1 or Run 2, etc...). The user types the name of the file must match the name of the file where the data is written (using writing to the file as VI)

    I enclose my vi of the trial.

  • Write continuously measure file problems

    I'm a new user of labview, so forgive me if it's simple, and do your best to not to judge my program because it is a work in progress. I tried to create an acquisition of data using a controlled box of activex and the complexity of a single loop slowed down so much that it doesn't work properly. I changed a loop of consumers/producers now, but when I try to start logging, it connects everything first and will not continue record all instances more unless I keep the enqueue switch. I do something wrong or is there a better way to do it?

    Your VI shows that you need the "enqueue element" button lit in order to the data in the queue to your consumer loop.  It is set to 'switch' action instead of "closure", which means it will remain lit once pressed until what you press it again to turn if off.

    But I think the problem you encounter, it's that you have a structure of the event in the same loop that has no timeout on it.  Event structure is sitting there waiting until that event occurs, then it lets you iterate, the loop can come back to wait on the structure of the event.  Events that are recorded in the event structure are stop, change the value;  Start logging, change the value; and the change in the value of several of your digital controls.  So unless one of these events occurs, your producer loop will keep a break.  I would recommend either a value of timeout on the structure of the event, or displacement of the structure of the event out of the loop and put in its own loop 'user interface '.

  • In palette I can find 'Write to worksheet File.vi' in 2015 of Labview?

    I get the signal from a sensor in DAQ hardware. After this treatment, I have three columns. Signal time - average - standard deviation

    I have trouble writing in an excel file. I used "Write to measure file.vi" but I don't know how to add columns inside and there is no place for labelling (give a title for the column). Also when I open my excel file, the time is as #.

    John

    I wouldn't really call it a workaround solution. This is the expected behavior.

    Build and write like a table and your waveform will be saved correctly.

    If you are going to write a point at a time, all you have to do is to keep track of what you want to use when you build your unique point to t0 and wiring waveform.

    EDIT: Is the column name 'Untitled' bug your client at all? It would have upset me. You can fix it by set the attribute of waveform for "NI_ChannelName."

  • write the size of measurement files

    Hello

    I save a lot of data in my controller and you want to write to a file measure tdms format.

    the problem is that the files are very large, if I use the "write to file measure" - on purpose - vi.

    If I use the 'writing TDMS' - function instead, the files are much smaller, with almost the same parameters.

    Is it possible to use the Express VI with the same efficiency, if I used the "writing TDMS" - function?

    Why are large files if I have the express vi?

    In general, avoid using express screws they tend to be just something you can put down and quickly have something that will work.  They also tend to be inefficient.  In the case of write it to a file as it opens and closes the file whenever you call.  With PDM, which causes a lot of overhead in the file.  If you were doing a Defrag TDMS on each of your two files, it should come out pretty much the same size.

  • Quickie: Write to the file measure VI, how to create the new file?

    I use the writing on measurement file express VI in my code and I plugged into it a control that sets the location where to save the file of measure

    The only problem is that the file of measure must exist first! I cant for example, from the Control Panel, click the directory to browse box, navigate to a folder and type a name for the file. It just says: file not found! It's like the control file directory opens a file to save in, rather than creating a new file to this location

  • 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.
