Good Morning,
I am extending a LabVIEW 2014.1 application, written by others, that runs on a NI 9067 cRIO. When I took it over, it used IRQs 0, 1 and 2 to coordinate events between the FPGA code and the RT. I'm a multi-decade software engineer, but have been working with LabVIEW only since last September.
I have added IRQs 3 and 4, but they don't seem ever to be received by the RT side.
Here is the RT loop that catches most of the IRQs -- you can see I've added 3 and 4 to it. It continues to receive 0 and 2, but 3 and 4 seem never to arrive. I'm pretty sure they're being sent, with Wait Until Cleared? set to FALSE.
My reading of the NI docs suggests that the 9067 cRIO is capable of supporting 32 IRQs. Is there a configuration setting somewhere that I've missed, that might be limiting them to 0, 1 and 2? Any other suggestions?
Thanks for your help!

Hmm. The IRQ just started showing up. Looks like this was reported in error.
