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.
Pattern Pattern is a binary value that contains the current port data.
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.
ADAC 5600 Config
The ADAC 5600 DIO Config VI allocates and configures a device's digital input port
(DIN 0-1) or DOT digital output port (DOT 0-3) subsystem returning a Device Handle to
be used in subsequent VI calls. This VI is only used with ADAC 5600 Series boards.
If the error in cluster contains an error from a previous VI call this VI does nothing and
returns the error in cluster unmodified in the error out. In the event of a previous error the
Device Handle is set to -1.
