• Viewer files TDMS file not found

  The VI I use currently is a slight modification of the example ContAcq & GraphVolt.  I've recently updated to LabVIEW 2009, and my Viewer TDMS open more TDMS files I record.  The files are there and I can open them using the example of ReadTDMS VI, but the viewer in my block diagram gives me 7 error: file not found.  There is a caveat, however.  If I save on a file that I had previously created, the file is located in the Viewer.  So if I save the file test1.tdms, the first time, it displays an error found the file, but the second time I save the viewer test1.tdms the file is located.  Any ideas as to why this is happening?

  Since my VI is close enough to the ContAcq & GraphVolt example (which does not work at the moment), this VI troubleshooting to solve my problem.

  
  

• TDMS defragment function blocks for labview

  Hello community,

  I have a few problems with the function of defrag TDMS in LabVIEW 2015 on a Windows 10 machine.

  My Viewer TDMS is crushed during the defragmentation of the tdms file I was trying to open (fragmented 700 MB text file). So I made a simple VI to use as test

  

  and it always breaks LabVIEW. Then, I tried a smaller file (70 MB) and it went well. Then a 120 MB... Hang again.

  Sometimes, the VI closes just, other times I get this:

  EIP = 0x35023DD4 access violation (0xC0000005)

  I was wondering, if anyone of you have had similar problems with function to defragment TDMS crashing?

  BTW, had no problems to open the same file with LabVIEW 2014 on a Win7 machine

  I also tried to run as administrator.

  See you soon,.

• Finish by mistake CSV

  I get all the values under the handle 'calc G level' in the csv file attached as a value when loading in a table view to rounding tiara.

  Kindly help with this problem.

  The CSV loader tries to guess the data type of column you. So in your case he leans on the front lines and guess int.

  in more recent versions of DIAdem, this was changed to guess that double instead of int.

  For DIadem 11.1 use ight be a solution.

  If you have a large number of these files, you can use a use to access. In it, you can switch the type of channel to double, and it would work out. If I remember well 11.1 already had the use wizard that facilitates the generation dataplugins.

  I hope this helps a little

• Write the spectrum of power + other tables to PDM

  Hello world!

  I am building a project of data acquisition, using compactDAQ to measure and record data from an accelerometer.

  The main objective is to save the data of acceleration, speed, displacement and frequency in a PDM spectrum, but I'm having some trouble it.

  As you can see in the attached file I had coveted, data of the wizard Express in a waveform to unbundle + build using waveform, after that I wired this waveform of a generation a table with data ACC, of speed and movement.

  The problem arises with the viewer TDMS data reading because the plot of the frequency band is not the x-axis with the right values, instead display the data of frequency it indicates the date and time that does not correspond with the PC, but the fact is that I need the frequency values.

  Is it possible to change and enter the correct values in the TMDS file?

  Thanks in advance,

  Omar

  The TDMS Viewer included with LabVIEW is not going to meet the needs of each.  And this is a case where it is inadequate.  Your data is stored correctly (at least the image looks right.  Also next time code postal no pictures.  Attach a VI or a code snippet.

  When you read your data PDM Regularisez using a DDHN reading him indicate you the type of data to expect, and there you can provide an analog waveform.  Then when you read back you will have the same dT and T0 he wrote with.  The problem with the Viewer is probably does not know it is a waveform and is simply read data from amplitude and then confuse around the X axis.

  You can write your own code to read the file, make a copy of the existing Viewer, then change it. Or my favorite is try Scout by Signal.X.  They took the standard TDMS Viewer and gave it an overhaul.  You might get lucky and open the data normally here.

• Life-long wrote only 20 s

  I'm trying to change the example Acq Cont & chart voltage so that it shows two analog channels and wrote both of these strings in a file.  I was able to do so and record for at least 1 minute two days ago, but yesterday when I tried to run the vi, it would only write 20 seconds no matter how long I let him to save.  I went back to the example originial vi this morning to try to run that one, and he writes too only 20 years.  It will show the space for the number of seconds during which I left it to save on the time axis in the PDM Viewer, but there is no data plotted.  Is this due to a setting I can I unconsciously changed in LabVIEW, a framework to the viewer TDMS itself, or something else entirely?  I've only been recording noise so far to test my vi, but I can post one of my TDMS files if this will help.

  After playing with other ways to read the files, I found that the viewer TDMS was simply not read all samples in the file more.  Fortunately, I managed to find my own solution (very simple)!

• Tiara taking much time to load the TDMS 700 MB to the data portal

  I'm trying to load a file of 700 MB TDMS in DIAdem, sampling frequency of 4 channels 10 Hz for 4 days. When I drag the file in the data portal, tiara freezes, its on a 2GB machine, a file that is located on the desktop, not running other programs and it is went 50 minutes without being able to load before I did leave. seems to work fine, although on smaller files. I was wondering if this sounds normal and if anyone knows a way around him.

  Yin

  Hi Yin,

  You can defragment the TDMS file loading in DIAdem programtically:

  TDMSFileName Sun: TDMSFileName = "C:\Dokumente und Einstellungen\GrRomaiS\Eigene Dateien\LabVIEW Data\ttt.tdms.
  Call DataFileLoad ("" & TDMSFileName & "","TDMS","" ")

  Please note that in this case, you will need to replace at least"<" and="" "&"="" in="" your="" filename="" (not="" contained="" in="" example="" code="">

  In addition, we have incorporated a fix in DIAdem 2010 SP1 that will speed up loading files TDMS (for example containing explicit time strings). We hope to see DIAdem SP1 this year...

• See the tiara reduced data in VIEW?

  Hello

  I installed the evaluation version 15.0 tiara

  Then I found my data on a SQL Server and load in data manager (Datenportal): (see photo)

  Now, I want to view my data in the VIEW tab and have a problem:

  This table includes data for several PP (PP means place of tests and has values whole 1.16).

  Question: can I display data in the VIEW tab only when e.g. PP = 3?

  I tried to write a script, but it's too slow (there is 6892777 lines in this table).

  Adding the line directly to the DISPLAY is fast, so it is also possible to add lines where PP = 3?

  Thanks in advance

• TDMS files viewer used in a dialog box

  I would use the viewer of TDMS files within a VI dialog box. The problem occurs if I change the properties of the VI - appearance of window - window modal behavior (it should be modal).

  When I click the button and run the viewer of TDMS files become two modal windows (my Viewer file VI and PDM) and 'lock' to the other: I can't control any of them.

  Is it possible to use the viewer of TDMS files as a dialog box?

  Thanks in advance,

  Ljubo.

  We remember, made you changes to a copy of the TDMS files viewer and not on that of VI.lib. With a upgrade/reinstall of LabVIEW, you will forget this small change, and you're back to square one.

• TDMS files viewer and view the contents of the DDHN does not give the same answers.

  I am hoping that there is a simple explanation for this problem.  If I use the PDM File Viewer, it can successfully open my data files large experiment.  The contents are listed without any problem.  Now, if I use the VI of PDM list content, I expect to see the names of groups and channels without data in an indicator.  Instead, I get only 1 group and its associated channels.  Why this discrepancy? Thank you.

  

  *.Tdms_index always write protected files? Could you try to delete the index files and open the files without them tdms (LabVIEW will generate new files to index if you do that)?

• TDMS Viewer and excel display different data

  Hello

  I have a problem of reading/viewing my PDM file. My file contains 37 channels and about 7 000 samples per channel. (Just this file... Later, I have to develop on many more ~ 150 k samples per channel)

  Now my problem is: if I open the PDM file with VI TDMS files Viewer, it starts to change the channel after ~ 1000 samples (Channel 29-37(MM1-MM9) should always be-32768, but after 1000 samples, the channel passes their place

  My analysis of switching: after ~ 1000 channels 29-37(MM1-MM9) is the 11-19 after ~ 2000 on 30-1 after ~ 3000 on 12-20, etc...

  Besides the switching channel there is a block of lines ~ 30 only filled every 0 ~ 1000 samples

  But if I open the file in Excel with the PDM-Addin is to show the correct data. Why is this and how to fix the Viewer?

  Hope you understand what I'm trying to say

  I have a my TDMS attached as a ZIP file, could not fix a PDM directly.

  It must be a bug of PDM, not the file viewer component. We will go is studying the issue. Workaround for you call the node "PDM defragment" to defragment this file, then it might appear correctly in the Viewer.

  According to your file, I found that the file has been created by TDMS Advanced knots. You define 10000 samples for an interlaced channel, but you write only 499 samples for a channel in writing. I suggest setting the sample counts exactly acrrording how are going to write.

• Store tabular data in file TDM tiara.

  Hello

  Is it possible to store tables in CT files?

  After processing the data, my results are a list of values that is in table form. And normally save us only the TOC file (and not the file TDR), in this case if I want to save the table, that I have prepared what method could be used?

  I hope that the issue is clearly else let me know.

  Thanks in advance.

  Kind regards

  fazshah.

  Hi fazshah,

  Once you calculate the scalar measure to display your table list in the text field, first save this metric as a property attached to the root, or a group or a channel in the data portal:

  Data.Root.Properties.Add 'PropName', varValeurProp
  
  '----------------- or -------------------------
  
  Set Group = Data.Root.ChannelGroups ("GroupName")
  
  Group.Properties.Add 'PropName', varValeurProp
  
  '----------------- or -------------------------
  
  Adjust the strings = Group.Channels ("ChannelName")
  
  Channel.Properties.Add 'PropName', varValeurProp

  You can add the formula to the list of text field that displays this property you just write:

  PropName = @Data.Root.Properties ("PropName"). Value @.
  
  PropName = @Data.Root.ChannelGroups ("GroupName"). Properties ("propName"). Value @.
  
  PropName = @Data.Root.ChannelGroups ("GroupName"). Channels ("ChannelName"). Properties ("propName"). Value @.

  You can also reference groups and channels by digital instead of the name index, if you prefer.

• TDMS.dll error loading file in tiara

  I'm trying to load a TDMS file written in LabVIEW 2010 in DIAdem 2010, but the error attached indicating an ACCESS VIOLATION in tdms.dll.

  I have several machines that this file loads into DIAdem 2010 of course, but of course on what I need to work was the only one that it does not work on.

  The machine in question is a 'new' installation of Windows XPSP3 with one minimum of other stuff installed (it's a Dell Optiplex GX620, if this themes).  As mentioned, the file load fine on several other machines with DIAdem 2010 on it.  It works very well on the machines run Windows XPSP3, XPSP4 and Win7 (all Dell machines).  I have attached a list of applications installed on the PC in question.

  Anyone have any ideas?  There are programs that are not compatible with DIAdem?  Are there any installers that DIAdem (or tdms.dll in particular) that depend on must be installed also?

  I copied the newer DLL on the machine that did not work, and that seems to have solved the problem.

  2010f2 LabVIEW installs a newer version of the DLL that DIAdem 2010 don't?

• Simultaneously view several TDMS files?

  We store the data of 2 channels into 2 separate TDMS files, but I need advice / analyze the togther.  How can I open two or more TDMS files at the same time?

  Why don't you write just a VI that reads files, extracts the data of interest, and then displays the parts you want to see together?

  There is also a plugin Excel for PDM.  I guess you could open two instances of Excel and to compare the data in this way, even if I never tried.

  Also nicht etwa completely frei. :-(

  for example id = "usi.seq.MSN17.Time" muss ubergehen nach "usi1" usw.

  DAS hat seinen Grund in der der Geschwindigkeit tables of choice.
