Hi, I've been trying out DCAF, and I am having trouble getting the FPGA module to work. I compiled a simple FPGA program that allow me to turn on/off the FPGA LED, as well as setting four voltage outputs to an analog output module. The FPGA by itself runs fine, and the bitfile been flashed into memory. I decided to only have one engine on the cRIO in my DCAF editor, which contains an FPGA Module configuration and a UI Reference configuration. My main vi for the cRIO is similar to the "cRIO Main.vi" in the Temperature controller example, and I used the editor to generate my includes.vi. My user interface is called "Test UI.vi" I added the *.pcfg file to the cRIO at /home/lvuser/natinst/bin/TestSystem.pcfg When I run the main vi, I get an error: Error 7 occurred at NISE_error generator.viPossible reason(s):LabVIEW: File not found. The file might be in a different location or deleted. Use the command prompt or the file explorer to verify that the path is correct.=========================NI-488: Nonexistent GPIB interface./TestBench_FPGATarget_FPGATest_a8r3rSxImxM.lvbitx I don't understand what the error means, as I am not using the GPIB interface, but I do recognize the bitfile name used in the FPGA. What am I doing wrong? Regards, Linus

Thank you Jacobson for your help. Now it works. I learned we have to: set under the cRIO Configuration: "home:\lvuser\main.lvbitx" (even if it doesn't look correct) set under the cRIO Configuration: "RIO0 Not sure if it is necessary, but I've also used RIO0 instead of "rio://10.0.0.99/RIO0" under FPGA Module Configuration->Rio Device:

Solved!

Thank you, my program works now. I had to put "RIO0" as my RIO Device in the FPGA Module Configuration.
