Issue Details

I have a cRIO-9074 and an ethernet RIO NI-9149. I would like to run an FPGA VI on the NI-9149 from a host VI on the cRIO-9074. Previously, this worked when using LabVIEW 2015 SP1 f10, LabVIEW FPGA Module 15.0.1, LabVIEW Real-Time 15.0.1, and the CompactRIO Device Drivers 15.5. 

I recently updated all of our LabVIEW software to the latest versions (LabVIEW 2017 f2, LabVIEW FPGA Module 17.0.0, LabVIEW Real-Time 17.0.0, CompactRIO Device Drivers 17.6). Now, when I try to open an FPGA reference to the remote NI-9149, I get error -63193 ("The requested feature is not supported.") and cannot run the FPGA VI.


Currently there is a bug between the 9149 and cRIOs that run VxWorks as their Real-Time operating system.. To workaround:
  • Downgrade your versions of software back to the original 15.5 system.
  • Use a different cRIO controller¬†that does not have VxWorks as the OS on the system.
