Owning Palette: TDM Streaming VIs and Functions
Requires: Base Package (ETS, VxWorks, Windows)
|file format version specifies the file format version for the .tdms file. Refer to the NI Developer Zone for more information about the file format of .tdms files.
|file path is the full path to the file you want to open. If you use this function to create a new file, the file extension of the filename you specify in file path must be .tdms. Otherwise, this function automatically appends .tdms to the filename you specify. If you use this function to open or update an existing file, you do not have to ensure that the file extension is .tdms.|
|operation specifies the operation to perform.
|byte order specifies the byte order, or endian format, of the data in the .tdms file. Byte order specifies whether LabVIEW represents integers in memory from most significant byte to least significant byte or vice versa.
|error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.|
|disable buffering (Windows) specifies whether LabVIEW opens, creates, or replaces a .tdms file without system buffering. The default is TRUE, which means you disable system buffering. Disable system buffering can speed up data transfers in certain situations. If you have a small amount of data to transfer, you might not notice a difference if you disable buffering. To read or write a data file to a Redundant Array of Independent Disks (RAID), consider opening the file without buffering to speed up data transfers. To read the same set of data repeatedly from the computer, consider enabling buffering.|
|tdms file out generates a TDMS file reference to the .tdms file on which you performed the operation.|
|error out contains error information. This output provides standard error out functionality.|
Refer to the following VIs for examples of using the TDMS Open function:
