Bridges, routers, and gateways
Devices that provide a connection between CAN-based networks and other wired or wireless communication systems are distinguished as bridges, routers, and gateways, depending on their functionality.

Routers interconnect networks at the network layer, and gateways link networks with different application layers.
Routers and gateways that comply to the appropriate CANopen specifications are easy to integrate into CANopen networks. Some of these profiles are already published:
