how to playback tdms files

[ygupta]

Hi, I have recorded data in multiple tdms files using the write measurement file express vi.now I want to add this option to playback the data collected as it was acquired. I have tried to do this by using the read measurement file express vi. But I got this error, Error -2525 occurred at TDMS Read in Read TDMS File.vi

possible reason(s) Labview:TDMS file data could no/t be converted into specified data type.

I would really appreciate any help on how to do this.

Thanks,

How you "playback" the tdms file? Is that in LabVIEW, you made some VI code to read the data back? It seems the data type you used to read is not the same to the original data type in the file or convertible.

Hi YongqingYe,

Yes its a vi I am trying to design which can read back the tdms data files recorded earlier (using another vi) and displaying it on a graph as it was acquired. I am trying to get something similar to the playback feature in signal express 2009.

I tried to read in a tdms file using the read measurement file express vi. and I selected the tdms option in the express vi's settings.  have i made a mistake in setting up the express vi?

Thanks,

I recommend you use TDMS nodes instead of Read from Measurement file for your application. The nodes are in Programming->File I/O-> TDM Streaming, hope it can help!
