• How to turn Pix timestamp of the log messages in the buffer

  How can I activate the timestamp of the log 'stamped' PIX messages? I activated the "record timestamp" command that generates timestamps for 'syslogd' messages but my messages saved in the buffer do not have a timestamp on them.

  I'm running ver 6.2 (2) 'warnings of logging in buffered memory ".

  Unfortunately you don't have. As you have seen, the "horodateurs log" command the timestamps on the syslog messages, but still put on the console messages.

  There is a bug already open about it, CSCdu18237. No word on when it will be resolved, however.

• Failed to export the log to Excel file. Continuous time?

  Hello

  I used Signal Express to record some Bio signals for my project, but I forgot to save it as I will, so was all the data in the log file. When I tried to export the file to Excel, he says that I can not export the log in excel, the system does not support non-continuous time... and I can not convert ASCII or... What should I do? Thank you

  Hello Tingaling,

  To display your .tdms file in Excel, you can use the TDM Excel Add-In for Microsoft Excel (see the link below on how to download/install add it in). Once the Add-In is installed, launch MS Excel, select Add-Ins in the menu bar and click on importing TDM icon (to select a .tdms file). In addition, I was able to launch the SignalExpress and import your files .tdms (file"importing" logged signals from TDMS files...) and correctly convert the text to display files in Notepad and Excel (expand the journal tree and right-click on the log file' convert to text, and then select a location to store the file .txt.) Then, launch Notepad or Excel to open/view the file). I hope this helps!

• Get "... a file and invalid format." (Error no. 11) "when you import the .tdms file in DIAdem 11

  I developed a script to process the .tdms file in DIAdem 11.1, now I deploy the script on the same PXI system that created the .tdms file.  This system had DIAdem 11.0, but when I try to open (DataFileLoadSel) the file tdms in my script, I get the error message:

  "D:\MyFileName.tdms" has a format invalid gall.  (Error no. 11)

  Tdms files are created by a LabView application.

  If I delete the index correspondin .tdms file, I get a little further, it loads the first two of the four groups, using DataFileLoadSel on the first group and DataFileLoadRed on the 2nd group, the third group, another DataFileLoadRed, I get the following error:

  Error in (line: x,: y):

  Unable to load the 'D:\MyFileName.tdms' file with the charger "TDMS.

  Additional information:

  Cannot open the file 'D:\MyFileName.tdms '.

  Is there a difference between DIAdem 11.0 and 11.1 affecting the .tdms file import, if I can get around it?

  Thank you

  Hello eberg,.

  Before we get into more detailed error recovery, could you please try to install the format TDMS 2.0 on the computer of DIAdem 11.0 (DIAdem 11.1 and LabVIEW 2009 come with TDMS already installed 2.0 stuff).

  Hesitate not to download it here: http://zone.ni.com/devzone/cda/tut/p/id/9995

  Once installed, please try to run the Scripts (in DIAdem 11.0) and let us know if that fixes the issue. He could not help to install this, but it's a quick thing to try before dig us more deeply into the question.

  Best regards

• Set the format digital u32 when writing of TDMS files

  We use two meters of a PCI-6251, with two counters in the mode of angular position, to measure the angular positions of the two optical encoders 1000 per second for intervals of 10 to 20 hours.  We are writing to write files using PDM.  The files are very large, about 800 MB, but it is acceptable.  Convert us the TDMS files in .txt files, and then the data from .txt files are analyzed in Mathematica.

  My question is: How does one control the digital format of the data that is written in TDMS write?  At this moment we have two counters of the value of the product N = 10000 numbers U32 samples are then transmitted continuously to a TDMS file every 10 seconds.  The counters are using units of ticks (integers) and we would like to see whole in our data files.  We are convinced that the counters are producing U32 to the format number, since we see the correct U32 integers in the indicators on the front panel and we see labels on the value axis on our waveform graphs are integers, not real numbers.

  But it is also clear that Scripture TDMS puts double-precision (64-bit) numbers floating point in the PDM file, not numbers of U32.  The double-precision floating-point numbers cause our .txt files to be twice as big as they should be - these .txt files are half full with useless zeros and decimal points.  In addition, when you convert the U32 to double-precision real numbers, it seems to be a loss of precision as a result of writing of PDM, which is not acceptable.

  Our experience produces pairs of integers: U32 (or I32) format.  We could even get away with numbers I16.  Is it possible to get our data to stay in U32 (or same I16) format when they are written to the TDMS file?  What controls the digital numbers written to tdms?  Do all the numbers written in a PDM file end up being written as floating-point numbers double-precision?

  We use LabVIEW 8.2 on a PC running windows XP.

  If associate you TDMS write U32 data, data in the file will be U32. Floating-point conversion probably occurs when you read data from the file back. You can change this by plugging in a U32 empty table at the entrance of 'data type' reading PDM.

  You can check the data type in the file by examining the channel properties in the viewer of TDMS files. If NI_DataType is 7, given in the file are U32. If it is 10, data are floating point.

  Hope that helps,

• Transfer TDMS file cRIO 9076 PC locally using Labview code problem

  Dear all

  I use LabVIEW 2013 with cRIO 9076 for datalogging PDM.

  I try to transfer the logging queue (.tdms) cRIO to the computer via the LabVIEW FTP software. The transfer is OK but computer I can't open the file-68007 error.

  It's ok when I copy the cRIO on computer file ( ftp://192.168.2.102 and manually copy the file)

  How can I fix the ploblem and LabVIEW FTP allows us to trnasfer file.tdms?

  Thanks and greetings

• TDMS file corruption when using FTP

  I use FTP to transfer files a cRIO to computer TDMS.  The transfer looks like it works; However, when I try to open the crowd using TDMS files Viewer, I get an error indicating that the file in not a PDM standards.  That being said, I use Windows to FTP the same file to compare.  I use the PDM viewer to open this file very well... no problems.  Have any ideas?

  Did you find the difference between the size of the TDMS files before and after the transfer? If so, maybe it's quite possible that the "transfer mode" software FTP questions, maybe you can try to use "binary" instead of "text" for fashion?

• 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.

• Display the results in corrupted file?

  Hi team, support

  I have a long clip of 2 h in PP I send to return to the preset in 1080 p H.264 Youtube. The clip should take about 6 hours to render, and the file size should be about 13 GB in the end.

  I tried three times to make the video and while it will run for six hours in the SOUL, the resulting file will be approximately 64 k and corrupt.  I tried to export the clip directly from PP and while it takes the same amount of time to make, I noticed it will save video and audio clips (.mkv and .aac or similar?), once it reaches 100% it deletes the audio and video files and the resulting .mp4 has the same corrupt problem.

  I was able to export successfully to the clips in the past, including this, but one of an earlier version. I try to export my product over, but to no avail now. I tried to export the file to the PC and mac environments. Any ideas? Thank you.

  What version of Media Encoder do you use?  When your finished encoding, you see an error or warning in the status column?  You can view a log (file > see the log) and errors (file > show errors).  You see everything related to failure?

  In addition, make sure that your destination drive has enough space.  In order to generate a 13 GB file, it must be at least 26 GB of space for a treatment of file (13 GB for final output and another 13 GB for temporary treatment file). After all the processes are carried out, a temporary file is deleted.

• Remove the log during recovery, but everything is ok

  Hello
  
  I delete the log during recovery file, insert a value in a table and commit, it is committed and no error in the alert.log file
  I turn on logfile, it switches, once again no error
  
  What is the reason?

  But when I commit, where do the Oracle stores data?

  First of all in the log buffer which is empty on commit to the CURRENT redo log in the redo log writer.

  As stated previously the writer newspaper most likely open the file before you delete - so he acquired a file descriptor and is still able to write to this file, even if you subsequently deleted. The journal writer retains the redo log permanently open at least until the file becomes inactive (I think even the file handles are never closed for performance reasons; but this should be verified).

• Card data scope of device to the TDMS file buffer

  How transfer brought data card device buffer to TDMS file directly bye passing buffers LabVIEW and Windows. In the same way as DAQmx configure logging (VI) do we have any function scope?

  The API OR-SCOPE doesn't have the ability to record data acquired directly on the disc like the DAQmx API offers.  All data must be retrieved from the on-board memory, which makes data transfer OR-SCOPE kernel driver via DMA, and a copy must then happen to transfer data from the space of the kernel in user space (LabVIEW), how it can be manipulated.

  The main reason for this flow is because the calibration scale occurs in the NOR-SCOPE driver and not the material.  So if you were to save data directly to the disk as DAQmx, he stock raw ADC codes, without correction calibrated.  The API OR-SCOPE allows to recover the coefficients of scale if you want to apply them at a later date after extraction of the data from the hardware.  To optimize flow of data applications, it is recommended.

  The only exception to the logging directly on the disk would be the Oscilloscope Reconfigurable SMU-5171R.  It is being implemented with LabVIEW FPGA firmware using the design of Instrument libraries, code is open for editing.  With the open nature of this software stack, it is possible to implement "direct to TDMS" functionality with LabVIEW FPGA Read region node.

  I hope this helps!

• DAQmx PDM, add the external value to the log file

  Hello

  I would like to know if it is possible to permanently add an external double value to the TDMS file that is created by the DAQmx Configure logging (PDM) VI?

  Thus, for example, I collect double data of 8 channels, DAQmx, speed of 1 Hz (analog double, 1 d). I'll get these 8 values with corresponding time stamps in the TDMS file created. Is there a way to "tunnel" a double value external to the same TDMS file?

  If there is no such option, I will configure just the TDMS logging explicitly not through the DAQmx driver.

  Thank you!

  with any possibility of foor loop iteration time zero will give you a default value of reference if your reference will not be valid in this case.

• The decisive TDMS file size when running.

  I have a request where the .tdms file can grow very quickly, due to the amount of stored data - 7 channels of data acquisition in 50 000 samples dry.

  I want to determine when the file has reached about 2 GB and close the .tdms file and create a new one with a different/timestamp name.  I want to break these files due to portability problems.

  It is, how to determine the size of the .tdms file?  When I try to give the Sub - VI "to get the size of the file" the .tdms, a GPIB controller file path must be in error of the charge occurs.  Also, the refnum of the tdms file is not the same as the file refnums, so the Subvi "get file pointer" will not accept the PDM refnums.

  I could probably calculate somehow what is happening in the PDM file, but that seems to be a workaround and will not exact due to the header information.

  You can't get the size directly from the refnum file, but you can probably still get the size another way. Use the file/directory information of the pallet of Advanced File i/o. It takes a path as input, not a refnum. This should give a specific semi file size value, although it will be possible that there is data to cache that has not yet been emptied to the file. Yet, when you talk about the file sizes in the range of 2 GB, it should be close.

  It is roughly the same thing that I look in Windows Explorer as the TDMS file size expands as it is written.
