Inputs/Outputs

  • c1du8.png byte array or file path —

    byte array or file path specifies the byte array or file path from which to create a .tdms file in memory. The byte order of the byte array or file on disk, if specified, determines the byte order of the .tdms file in memory this function creates.

    If you do not specify byte array or file path, this function creates an empty .tdms file in memory that uses the byte order of the host computer.
  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • ignrn.png tdms file out —

    tdms file out returns a TDMS file reference to the .tdms file on which you performed the operation.
