CiA 461 series updated
CiA has released version 2.0.0 for CANopen load cells, scales, and HMI (human machine interface) devices. The four documents are published as draft specification proposals. They introduce functional safety capability compliant with CANopen Safety.
History of CAN technology
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.

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. Close to two billion of CAN nodes are installed annually. And this is still growing. Compared with these figures, the number of CAN fellows organized in the nonprofit CiA users’ and manufacturers’ group is very small. Several have left the CiA community in the last years. Some of them are coming back due to the CAN FD development. And there are many things still to do.
We take the already existing ideas in communication technology as well as in human communication, arrange them newly, and new specifications and products are born.
