CAN 2020 events

The future of CAN (FD) technology

CAN in Automation (Germany) has scheduled several CAN 2020 events. They all deal with the future of CAN FD, CANopen FD, J1939 on CAN FD, etc.

Among other things, the content of the CAN 2020 event covers basic technical information on CAN FD, the impact on higher-layer protocols including CANopen, J1939, etc. (Photo: CiA)

The CAN protocol was introduced in 1986, 30 years ago. The first cars using CAN networks were launched five years later: the legendary S-class model W140 by Mercedes. In 2016, CiA expects an annual installation of 1,8 billion CAN interfaces.

To inform its members and associated CAN fellows about CAN FD opportunities, the nonprofit association CiA organizes information events. They are called CAN 2020 because the first cars using the improved CAN protocol will be on the roads in 2020. In these events the CAN FD technology is described, further requirements are collected, and the next steps are discussed. Other topics include several middleware options (e.g. OPC UA) and to make CAN nodes a participant on the Internet (IoT).

CAN FD was officially introduced in 2012 at the 13th international CAN Conference (iCC) at the Hambach castle when the automotive industry required more bandwidth for CAN networks. Since then, several companies have developed CAN FD-capable semiconductors. Step-by-step CAN FD will replace Classical CAN. But there is no compulsion to use the increased speed: you can still run CAN FD with a single bit-rate up to 1 Mbit/s. Nevertheless, you can use longer frames with a payload up to 64 byte.

In the first CAN FD generation, the automotive industry will use data-phase bit-rates up to 2 Mbit/s in star-like or hybrid topologies (bus-lines with longer stubs). After gaining experiences, carmakers will increase the speed to 5 Mbit/s and may use dedicated ringing suppression circuitries. Non-automotive users might choose a linear topology with very short stubs, in order to reduce ringing on the bus-lines.

The participation for members is free-of-charge. Non-members have to pay a small fee to compensate for expenses. The events are dedicated for decision makers in device and system development, technical marketing, and sales. First events are scheduled in Nuremberg, Germany (May 10th), Birmingham, UK (May 13th), Tokyo, Japan (May 25th), Berlin, Germany (September 27th), Lyon, France (October 6th), Essen, Germany (October 27th), and Utrecht, Netherlands (November 8th). Other locations in China and India are planned, but not yet scheduled.
