Currently, NI-CAN and NI-DNET cannot be installed on the same machine at the same time, regardless of the number of cards that are installed in the machine.
However, with some work, it is theoretically possible to install only NI-CAN, implement the CAN interface as normal, then, since the DNET protocol is built on CAN, use NI-CAN to implement DeviceNet functionality on another card.
