Start Asynchronous Call Node

Owning Palette: Application Control VIs and Functions

Requires: Base Development System

Starts an asynchronous call to the VI indicated by the reference input. Depending on how you prepare reference for asynchronous execution with the Open VI Reference function, you can either ignore the VI after calling it or collect its outputs at a later time with the Wait On Asynchronous Call node.

Details  Examples

 Add to the block diagram  Find on the palette
reference is a reference to a target VI that you want to call asynchronously. The reference must meet the following criteria:
  • Be strictly typed
  • Be prepared for asynchronous execution by the Open VI Reference function using either the 0x80 or 0x100 option flag. You can combine other option flags with these asynchronous options.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
reference out returns reference unchanged.
error out contains error information. This output provides standard error out functionality.
