You can use the UFF58 File I/O VIs to read both binary and ASCII UFF58 files. To read a UFF58 file, you first must use the SVT UFF58 Open File VI and the SVT UFF58 Get Function References VI, as shown in the following figure:

In the figure above, the SVT UFF58 Open File VI opens a UFF58 file. The SVT UFF58 Get Function References VI then gets all time waveform function refnums from the UFF58 file. The VI then passes the array of function refnums to the SVT UFF58 Read VI through a For Loop so that each element of the array gets passed in turn to the SVT UFF58 Read VI. After this VI reads all the time waveform data, the SVT UFF58 Close File VI closes the UFF58 file.

Use the UFF58 Advanced VIs to read specific records within a UFF58 file.

You also can use the Load from UFF58 Express VI to read both binary and ASCII UFF58 files. You do not need to use separate VIs to open the file, get references, and close the file if you use the Load from UFF58 Express VI.

Refer to the following VIs for examples of reading UFF58 files:

• SVXMPL_Read from UFF58 File (Time Waveforms With Records) VI: labview\examples\Sound and Vibration\UFF58\SVXMPL_Read from UFF58 File (Time Waveforms With Records).vi

• SVXMPL_Read from UFF58 File (Time Waveforms) VI: labview\examples\Sound and Vibration\UFF58\SVXMPL_Read from UFF58 File (Time Waveforms).vi
