An event case is handling an event that another case in that Event structure is already configured to handle. In the following example, two cases in the Event structure are configured to handle the Timeout event. You must reconfigure one of these cases to not handle the Timeout event.

You can correct this error in the following ways:

  • Delete the duplicate event case by right-clicking the duplicate event case and selecting Delete This Event Case from the shortcut menu.
  • Edit the event handled by the event case by right-clicking the Event structure and selecting Edit Events Handled by This Case from the shortcut menu to display the Edit Events dialog box. Edit the event case to handle an event not already specified by this Event structure.

Before you configure events for the Event structure to handle, review the caveats and recommendations for using events in LabVIEW.
