CiA updated the page "History of CAN technology". In February of 1986, Robert Bosch introduced the CAN serial bus system at the Society of Automotive Engineers (SAE) congress. It was the hour of birth for one of the most successful network protocols ever. Read more.
CAN lower- and higher-layer protocols
The knowledge pages provide technical information on the CAN data link layer protocols and several CAN physical layer options. CiA updated this page, take a look at it.
J1939 technology day
On April 29, a J1939 technology day in English language takes place. This CiA technology day presents status and future of J1939-based networking. This includes the standardization activities in SAE, ISO, and IEC. You can still register.

CiA seminars in March
The first CAN and CANopen seminars take place on March 23 and March 24. To increase attendee’s safety in times of the coronavirus, the CAN and CANopen seminars are still scheduled in a web-based format.
The problems are solved, not by giving new information, but by arranging what we have known since long.
CiA community
The CAN community is huge. More than two billion of CAN nodes are installed annually. And this figure is still growing. The number of CAN fellows organized in the nonprofit CiA users’ and manufacturers’ group is much smaller. Due to new CAN data link layer (CAN XL and CAN FD Light) and new CAN physical medium attachment developments (CAN SIC and CAN SIC XL), the membership is growing, too. There are also new members interested in CiA profile developed for new markets such as battery management, fire-fighting equipment, etc.
“We take the already existing ideas in communication technology as well as in human communication, arrange them newly, and new specifications and recommendations are born,” said Holger Zeltwanger, CiA Managing Director.
