WA Read from File VI

Owning Palette: Utilities VIs

Installed With: Advanced Signal Processing Toolkit

Reads data from a spreadsheet text file that contains a 1D array, a 2D array, a byte stream file of single-precision numbers, a byte stream file of 16-bit signed integers, a file created with the Write Waveforms to File VI, a WAV file, a JPG file, or a BMP file.

file type specifies the type of the source data file.
0Spreadsheet Text File (default)
1Byte Stream File of SGL
2Byte Stream File of I16
3Waveforms Data File
4WAV File
5JPG File
6BMP File
sampling rate specifies the sampling rate in hertz. The default is 1 kHz.
error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
1D signal returns the 1D signal.
2D signal returns the 2D signal.
filename returns the name of the data file.
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error.
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
