Event Structure Support in LabVIEW Real-Time

Issue Details

Is the Event Structure supported in LabVIEW Real-Time?

Solution

Event Structure support in LabVIEW Real-Time is target-dependent. The differentiating factor is if a target has or does not have Embedded UI functionality:
  • For targets with Embedded UI functionality, the Event Structure supports both UI events and user events. Here, UI events are defined as events associated with Front Panel objects.
  • For targets without Embedded UI functionality, the Event Structure does not support UI events. Because Front Panels are not transferred to these real-time targets, any events based on a control or indicator will not work. However, the event structure does support user events.

Additional Information

Please see the Related Links section for documentation on the Event Structure, Event Functions, and Creating Custom Events. A VI snippet for creating a user event in real-time example is shown below.


Note: Although programmatic, the Value (Signaling) property is not available on LabVIEW Real-Time on devices without Embedded UI and will not be able to fire an event.
