CiA® 315: CANopen generic frame for wireless tunneling of CAN messages and for transfer of diagnostic data

The specification CiA 315 specifies a generic frame for tunneling CAN messages via a wireless transmission media. This is relevant for use cases, where parts of the application cannot be connected via cable, e.g. because of parts being motion. The objective of this specification is to allow bridging of two CAN networks via a wireless transmission media, as illustrated in Figure 1. CANopen devices providing a certain gateway capability between CAN and a wireless transmission medium (WTM), have to extract the essential parts of a CAframe, and have to transfer them via the WTM. As receiving device, they have to generate the original CAN frame again, at the receiver’s CAN interface.
