I'm trying to work up a document on our cRIO 9076 for the lab, and I'd like to include a schematic/block diagram of its overall internal structure...something like what PC motherboard makers give (example below). The internals of the RT controller are pretty easy to guess at, but I'm a little fuzzy on the connections between that and the FPGA, and between the FPGA and the chassis modules. Any pointers on where I should be looking (not in the manual, by the way)?
I haven't seen any internal block diagrams for the cRIO similiar to the one that you've posted. The closest I could find is the first figure seen in this article. There are block diagrams for our R-series cards however. You can find them in the manual here starting at page 2-1. They won't be exactly the same but leads to and from the FPGA will be similiar.
which specifies the controller-fpga connection as PCI, meaning much of the details are probably obvious with a better understanding of PCI busses. In any case, I've managed to start a diagram of my own that will suit my needs just fine.
