CiA and international standardization

CiA is committed to support international standardization within ISO (International Standardisation Organization) and IEC (International Electrical Committee) as well as the European standardization bodies (CEN and CENELEC). In some ISO standardization groups, CiA is an official liaison partner. CiA also accompanies national standardization on request.

Additionally, CiA co-operates with other nonprofit associations in the development of CAN-based specifications, recommendations, and guidelines. This includes reviewing and commenting of documents published by those organizations

CiA representatives participate in many of the CAN-related standardization activities by the above-mentioned international standardization bodies. CiA is also committed to submit on request its documents to them. CiA staff attends also CAN-related committees and task forces by SAE International.

CiA cooperates

CiA is open to develop CAN-based solutions with other nonprofit organizations. With Profibus International (PI) the CANopen interface profile for Profinet-I/O has been released (CiA 309-4). The CiA 420 series of CANopen profiles for extruder downstream devices jointly developed with Euromap has been published since many years. In cooperation with the EnergyBus association, CiA members have specified the CiA 454 profile also suitable for light electric vehicles including pedelecs and e-bikes.

Additionally, CiA and JasPar   cooperate in the development of CAN FD design recommendations for devices and networks. Regarding CAN-related specifications, CiA and Autosar have joined forces. Another partner is Open Alliance, coordinating data link layer security solutions. CiA also supports the AEF association in respect to CAN-based specifications for agriculture machinery.
