Event Structure Does Not Capture the "Signaling Value Change" on myRIO

Issue Details

I want to move data from one loop on my myRIO Real-Time to another loop. I understand that programmatically changing a front panel object doesn't generate an event unless you use the Val(Sgnl) property node, but why isn't the Event Structure picking anything up even with one?


​Event Structures do not fully work on Real-Time targets like the myRIO. This is because the Front Panel is executed on the host system while the Block Diagram itself is executed on the Real-Time system.

The myRIO is meant to run stand-alone and has no monitor connector (it is "headless"). Therefore it does not support Front Panels in full. The Val(Sgnl) Property Node will not create an event. Use Queues or User Events to pass your data between loops instead.
