Issue Details

Is the Event Structure supported in LabVIEW Real-Time?


Event Structure support in LabVIEW Real-Time is target-dependent where the differentiating factor is targets with and without 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 downloaded to these real-time targets, any events based on a control or indicator will not work.  However, the event structure does support user events. 
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 and will not be able to execute an event.
