Requires: Base Development System. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Waveform File I/O VIs to write waveform data to and read waveform data from files.
The VIs on this palette can return waveform error codes.
| Palette Object | Description |
|---|---|
| Export Waveforms to Spreadsheet File | Converts a waveform to a text string and writes the string to a new byte stream file or appends the string to an existing file. Wire data to the waveforms input to determine the polymorphic instance to use or manually select the instance. |
| Read Waveforms from File | 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. |
| Write Waveforms to File | Creates a new file or appends to an existing file, writes the specified number of records to the file, then closes the file and checks for errors. Each record is an array of waveforms. Wire data to the Waveform input to determine the polymorphic instance to use or manually select the instance.
