TDMS Write - Append to file

[bonestruca]

Hi,

is it possible tu append data to a TDMS file like you can when you use the Write to Spreadsheet VI ?

Storage -> Write Data can only save values as double. I need single.

Thank you for your help.

If you open an existing file with the Vi "TDMS Open" and specify as Operation "Open"  you should be able to append data with the vi "TDMS Write".

Moreover, concerning the data type, the help about the function "TDMS Write" states you can use SGL:

data is the data to write to the .tdms file. This input accepts the following data types:

• Waveform or a 1D array of waveforms
• Digital table
• Dynamic data
• 1D or 2D array of:
• • Signed or unsigned integers
  • Single, double, or extended precision numerics
  • Alphanumeric strings that do not contain null characters
  • Timestamps
  • Booleans
