This is an excellent presentation and congratulations to the EPS team for this substantial achievement!

A few questions come to mind:

1. What was the hardware platform that they ended up using for the commercial product? Was it a sbRIO/GPIC based solution or was it a cRIO platform as implied in the presentation. Any chance they can share which cRIO or sbRIO model was utilized?

2. Two very interesting slides were the System Overview slides, pages 14 and 15. At what rate were they able to run Vdc control loops on the RT? Also, is there a sample NI code that utilizes the DMA and interrupt style programming?
