Opens a file created with the Write Waveforms to File VI and reads one record of the file. Each record might contain one or more separate waveforms. To retrieve all records in the file, call this VI in a loop until the end of the file is reached.

This VI returns an end-of-file error in the error out output.

Inputs/Outputs

  • cpath.png file path (dialog if empty) —

    file path specifies the file where the waveform is located. If you do not wire this input, LabVIEW displays a non-native file dialog box instead of a native file dialog box.

  • ci32.png offset (records:0) —

    offset specifies in records which record to read from the file. The first record is 0. The default is 0.

  • cerrcodeclst.png error in (no error) —

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

  • ipath.png new file path (Not A Path if cancelled) —

    new file path returns the path to the file.

  • imsdt.png first waveform in record —

    first waveform in record returns the data of the first waveform in the record.

  • i1dmsdt.png all waveforms in record —

    all waveforms in record returns the data from all waveforms in the record. If there is only one waveform in the record, this output is identical to first waveform in record.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
