Hi, I am trying to create an exe file that uses I/O with a cRIO. I have successfully created the Main Vi that uses the fpga open function and my I/O works great for about 10 seconds when all of a sudden all of my front panel boolean LEDs flash and then none of my I/O works anymore unless I close the EXE and reopen it. I am not really sure what is going on whether coms become lost or if the code is overflowing or something. There are no error messages when this happens so there's not much debugging I can do with it I suppose. I'll share my Main Vi and the Vi with all my fpga logic. It's quite messy I am sure but bear with me. RunBench is the Main. PS the Main does indeed have a while loop around everything except the message part in the beginning, I took it out in hopes it would fix the failing part. Also I am going to add a close button going to the loop stop condition once I get it working as desired.

It looks like you are opening the FPGA repeatedly inside the loop, but only closing it once after the loop. I believe that will cause a memory leak. Move the FPGA Open BEFORE the while loop.

Shouldn't you also open the reference before the loop? (Instead of with every iteration?) Can you add an indicator to the various error wires inside the loop. What do they say? Where do you define the loop rate?

EXE Program Failing After Few Seconds

Solved!

I was using a 6 position terminal block as a ground point with jumpers going from each pad; one of the screws for the jumper was not tight so there was a 7V drop from one end to the other.
