Scan mode and FPGA

[sampriti]

I want to utilize some of my modules in Scan mode and some in the FPGA mode. Although I could create a hybrid project, I am unable to make a VI implementing both of them. I get an error as in the block diagram I have attached. I want to to read the analog inputs through NI 9239 using scan interface mode and put out the output through 9269 using fpga mode.Is that possible? I am a bit new to this.

Thanks in advance!

You certainly can't do what you were trying there.  You will need at least two VIs for this application.  You will need a VI running under the FPGA target that can read and write the purple nodes (FPGA IO nodes).  You will need a VI running under the RT controller that can read and write the variables, like the yellow node in your picture.  To talk between the two VIs, use the FPGA Interface pallette to read and write controls and indicators on your FPGA VI from your RT VI. 

Does that information get you a little unstuck for now?
