About us

CAN in Automation (CiA) e. V. is the international users' and manufacturers' group for Controller Area Network (CAN). The non-profit association was founded in 1992 and is supported by about 630 members, CiA' members develop CAN-based higher- Iayer protocols, e.g. CANopen and device profiles. CiA representatives participate in international standardization bodies (IEC and ISO).

Products and services

CiA develops and publishes specifications, recommendations, guidelines, and application notes, e.g. CANopen specifications for drives and motion control. The CiA test center provides CANopen compliancy assessment services such as CANopen device conformance testing and CiA interoperability testing. In addition, CiA provides diverse seminars and conferences for development engineers, system designers, and technical decision-makers.

CANopen specifications

Since 22 years CiA publishes CANopen specifications, e.g. CiA 301 specifies the CANopen application layer. CiA 402 profile specifies the CANopen interface of power drive systems. CiA 601 series specifies and recommends the usage of CAN FD hardware implementations.

CiA seminars

CiA provides devise seminars for development engineers, system designers, and technical decision-makers. Attendees receive basic information on CAN/CAN FD or CANopen.

CiA test center

CANopen device conformance testing is used to determine whether CANopen devices comply with the requirements of CiA 301 "CANopen application layer and communication profile" specification. CANopen interoperability testing is a CANopen network compatibility testing to determine whether CANopen devices can be integrated into a CANopen network and perform their function without causing any communication problems.

News & Innovations

For IIoT and Industry 4.0 based on well-proven CANopen FD
CANopen FD is well-suited for adding embedded networks to IIoT applications. The high communication flexibility, thanks to the powerful Universal Service Data Object (USDO), enables a simple access from any CANopen FD device to any other CANopen FD device during run-time. Furthermore, the higher data throughput offered by CANopen FD supports comprehensive condition monitoring and big data applications. In order to integrate CANopen FD networks into Industry 4.0 environments, CiA specifies the mapping of CANopen FD services and profiles to OPC UA.
CAN FD - Internationally standardized in ISO 11898-1
The CAN FD data link protocol overcomes the limitations of the Classical CAN protocol. CAN FD allows in the data-phase part of the data frame a transmission rate higher than 1 Mbit/s. The automotive industry will use 5 Mbit/s for software download using linear topologies, and 2 Mbit/s for star and hybrid networks. Possibly, up to 8 Mbit/s can be achieved in linear networks. Additionally, the data-field has been enlarged to up to 64 byte. The Classical CAN is limited to 8 byte. Both improvements lead to significant higher throughputs.
