TDM Measuerment File

[mimran]

Hi

I am using write to measurement file function to log my real time values in TDM file. I am having roblem in naming the Channel names because TDM function ignore my Channel names and use the Untitled keyword overthere. 

 Thanks

Hi mimran,

We can specify channel name in the configuration dialog as well as other properties.

If it doesn't work for you, would you please let us know which LabVIEW version you were using?

Thanks,

Mavis

Hi Mavis

I have got Labview 2009. And do you know how to convert TDMS file to XLS?

Thanks

Hi mimran,

You can try the TDM Excel Add-in to convert TDM or TDMS file to XLS.

Hi

Infact I did managed to put names for different signals using "Set Dynamic Data properties" Function.  Now I am getting output like

Time(Pressure)                                  Time*                            Pressure                             Time (Flow)                            Flow

04/21/2010 09:02:05                        0                                      -3.4                        04/21/2010 09:02:05                -3000    

04/21/2010 09:02:06                        1                                      -3.4                        04/21/2010 09:02:06                -3000    

04/21/2010 09:02:07                        2                                      -3.4                        04/21/2010 09:02:07                -3020    

04/21/2010 09:02:08                        3                                      -3.4                        04/21/2010 09:02:08                -3000    

Now I want to have  this type of output

Time(Pressure)                                                             Pressure                                      Flow

04/21/2010 09:02:05                                                              -3.4                              -3000    

04/21/2010 09:02:06                                                             -3.4                               -3000    

04/21/2010 09:02:07                                                             -3.4                               -3020    

04/21/2010 09:02:08                                                              -3.4                               -3000    

Thanks

Hi mimran,

Are you using TDM Excel-AddIn to import the TDMS file into Excel?

If you'd like display some of your channels instead of all of them, maybe you have to delete the channels from the TDMS file.

Currently the TDM Excel-AddIn shows all of the channels in the TDMS file. If you have request to display part of them, we could consider doing that in the future versions.

Thanks.

Hi

At the moment, I am using TDM Excel Addon for viewing the logged data.  But I am thinking to change the saved file to Excel format programatically. I know this is possible but have no idea how to do it.

I am using Write to Measurement File  function for creating a log file. So can you tell me how I can delete specified columns/Channels from TDMS saved file.

Thanks

Hi mimran,

Currently in TDMS, we don't support deleting a channel directly. You may use a walk-around in LabVIEW:

1. Read out all the groups and channels expert the channel you want to delete.

2. Write these groups and channels to a new file

3. Replace the old file with the new file.
