Event Structures Are Not Working on my CompactRIO (cRIO) Hardware in LabVIEW

Issue Details

I'm creating a VI on my cRIO and when I run it on highlight execution mode, I can see the event structure is not responding. Should this structure work on Real-Time based targets?


In general, Real-Time targets support only Event Structure with dynamic events, currently the only exceptions are cRIO-903X and 904X that run NI Linux Real-Time and also have display port or USB-C port (with display support) on them.

To work with Event Structures on those, you should first enable their Embedded UI on MAX.


Additional Information

Keep the following considerations in mind when using each Real-Time Operating System that comes with NI hardware.
