My thesis titled A Study of the DeviceNet Conformance Test and the Definition of the DeviceNeX protocol.

In summary it extends the existing DeviceNet protocol that uses 11-bit CAN identifier to 29-bit, making full use of the extra 18 bits. One of the great advantages of this protocol is that it allows the transfer of up to 10 bytes of I/O data, and reduce the interrupt rate to the slave devices since both source and destination addresses are placed at the identifier field - filtering can be applied.
