Recieving Error 2513 when exporting TDMS

[mcarroll45]

Hi,

I'm relatively new to labview and have been writing a program to graph pressure and RPM and export a TDMS of the data. When the program only had to export time and pressure in the TDMS it worked without error. Then I added one more array to the program (being RPM). When I ran the program everything seemed to work fine but when I went to export the TDMS it gave me the following:

"Error -2513 occurred at TDMS Set Properties in Function.gvi

LabVIEW: (Hex 0xFFFFF62F) LabVIEW does not support properties of the specified data type."

It still prints out the TDMS fine, but I can't figure out where the error is occurring.

Thanks in advance

Hi mcarroll45,

That error was being thrown at the TDMS Set Properties function. You were passing in a Variant Array to the property values input. You can input a string array with your properties instead using Number to Decimal String instead of To Variant. 

I would also recommending looking at the TDMS shipping examples for best practices for writing/reading TDMS files , such "TDMS Write Time Domain Data.lvproject" in Examples > Programming Basics > File I/O.

Thanks,
Frank
