Wait On Asynchronous Call Node

Owning Palette: Application Control VIs and Functions

Requires: Base Development System

Waits for an asynchronous call to a target VI to finish executing and then returns the outputs of the target VI. To use the Wait On Asynchronous Call node on a reference, you must include the 0x100 option flag as part of the options input of the Open VI Reference function when you open the reference. You also must call the target VI with the Start Asynchronous Call node.

reference is a reference to a target VI that you want to call asynchronously. The reference must meet the following criteria:
  • Strictly typed
  • Prepared for asynchronous execution by the Open VI Reference function with the 0x100 option flag. You can combine other option flags with this option.
  • Called by a Start Asynchronous Call node elsewhere in the calling VI
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.
