About us

The aim of the 1992 established nonprofit organization is to promote CANís image and to provide a path for future developments of the CAN technology. An important part of the organizationís effort is spent to develop and maintain the CANopen and the CANopen FD specifications as well as the support of all other internationally standardized CAN-based higher-layer protocols (e.g. SAE J1939, ISO 11783 series).

The association owns the CiA GmbH company offering services such as seminars, in-house seminars and conferences as well as publications (e.g. CAN Newsletter) and periodical emails (CiAís Weekly Telegraph and the monthly CAN Info News). Additional services include conformance testing of CANopen devices and general consultancy support (but no product developments).

More than 600 companies joined CiA. Each member may participate in any technical and marketing group. The CiA General Assembly elects the Board of Directors yearly and decides on the annual budgets.

Product groups


CAN FD design recommendations
CAN with flexible data rate (FD), standardized in ISO 11898-1:2015, supports an enhanced data throughput by keeping the robustness and simplicity of Classical CAN. CAN in Automation and its members develop and maintain CAN FD recommendations for device and system design. The documents of the CiA 600+ specification series are available here:
CANopen and CANopen FD specifications
CAN in Automation maintains the CAN-based higher-layer protocol CANopen. CANopen, standardized in EN 50325-4, unburdens the developer from dealing with CAN hardware-specific details such as bit timing. It provides standardized communication objects (COB) for time-critical processes, configuration as well as network management data. Further information is provided here: CANopen FD is the improved successor of CANopen. It is based on CAN FD and adds new features to CANopen, such as the very flexible USDO service or an enhanced diagnostic memory. CANopen FD was released in September 2017, in the document CiA 1301, by CAN in Automation. Additional information is provided here:
