Chapter 2 Digital I/O VIs
ADAC LabVIEW VI 76
Clear Acquisition (true) Clear acquisition determines whether the VI releases the device
after reading the specified number of samples. The VI should pass a TRUE to this
parameter when reading the last set of samples for a given acquisition. The default is
TRUE, which means that the VI reads data only once if this input remains unwired. You
typically wire this input to the terminating condition of a loop, so that when the loop
finishes the device is released.
error in (no error) Error in describes error conditions occurring before this VI executes.
This cluster defaults to no error.
Device Handle Device Handle is a numeric value that identifies the board's DIO
subsystem to be acted upon in subsequent VI subsystem calls.
error out Error out contains error information. If the error in cluster indicated an error,
the error out cluster contains the same information. Otherwise, error out describes the
error status of this VI.
