How to use NI 9264 and NI 9205 with cRIO-9151 and NI PXI-7813R

[sharter1]

Hi everybody

I am currently working on a real-time application with NI PXI-7813R (FPGA Card) and NI PXI-8184 (Embedded Controller). They are all in a NI PXI-1031 chassis.

I need to generate/receive analog signals.

I have already managed to use the SCB-68 with my NI PXI-7813R (FPGA Card) to deal with digital signals. (Connector 0)

On Connector 1 and 3 of my FPGA I have respectively cRIO-9151 with NI 9264 for the analog output, and cRIO-9151 with NI 9205 for the analog input.

• with NI 9264, I have on all the 16 output channels -10,5V (!!! Isn't it supposed to stay between -10 and 10V???), whether the vi is running or not. (But not when my PXI is turned out...)
• with NI 9205, I always get -32767 when the VI is running, whichever voltage I apply. (I tested AI0 and AI10)

Maybe is my material not configured properly? I made the configuration automatically, when I started the project, Labview detected the plugged devices.

Unfortunately, MAX does not seem to be useful because the inputs/outputs are on the FPGA...

Any Idea?

Thanks

PS: The VI on the FPGA is really basic, only read/write controls.

Hi

Back with the solution...

My modules were switched! Each of them was plugged in the wrong cRIO-9151.

This must have happened after the first configuration.

I noticed it when I right-clicked on my fpga device > RIO Device Setup. I wanted to recheck the peripherals, but Labview crashed.

I could also have seen "connector [number]" (automatically added by Labview) and the Hardware reference number (NI 9205 or 9264) in the project, and check if it was really what I had.

Hope my mistake will help somebody in the future...
