Chapter 2 Miscellaneous VIs
ADAC LabVIEW VI 80
ADAC Occurrence Config
This VI creates a DAQ Event Occurrence. The output occurrence is wired to a wait on
occurrence primitive which is used to provide asynchronous DAQ.
Device Handle (0) Device Handle is a numeric value that is used to identify the device
subsystem. The default Device Handle is 0.
error in (no error) Error in describes error conditions occurring before this VI executes.
This cluster defaults to no error.
Device Handle out Device Handle out contains the value of Device Handle in.
Occurrence occurrence is the occurrence value created. Wire this output to a wait on
occurrence primitive. Wire the output of the primitive to the part of your diagram you
wish to execute when the DAQ event happens and the occurrence is set. If LabVIEW is
unable to create an occurrence, the occurrence value is set to the Not a Refnum file I/O
constant.
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 Enum(erate) Boards
The ADAC Enum Boards VI reads in the ADAC-LVi.con file that contains the board
names and ID numbers used to represent the DAQ boards. The information containing
each board description is located in the ADAC-LVi.con configuration file located in your
main Windows directory.
