CANopen FD faster and with improved functionality

CAN in Automation (CiA) has released the CiA 1301 CANopen FD application layer and communication profile specification.

CANopen FD makes use of the CAN FD data link layer providing higher bit-rates (currently transceiver chips are qualified for up to 5 Mbit/s) and larger payloads (up to 64 byte per data frame). Compared with the classic CANopen application layer, the most significant difference is the introduction of the USDO (Universal Service Data Object). This service supports broad- and unicast communication as well as access to CANopen FD nodes in other network segments (routing functionality).

“CANopen FD meets the performance requirements of industrial embedded networking,” stated Holger Zeltwanger, CiA’s managing director. “It is optimized for front-end control providing sufficient bandwidth for more than 80 percent of commercial control applications.” The price for the CAN FD hardware is as reasonable as for Classical CAN.
