CAN FD standards and recommendations
Since end of last year, the second edition of ISO 11898-1 is published. It standardizes the CAN FD protocol as well as the Classical CAN protocol. The standard contains what the chipmakers need to implement the protocols in silicon.
The transceiver chips qualified for bit-rates of 1 Mbit/s and higher are standardized in ISO 11898-2:2016. ISO will publish the document within the next months. Additionally, ISO will release conformance test plans for ISO 11898-1:2015 (ISO 16845-1) and for high-speed CAN transceivers (ISO 16845-2). Both test standards will be available by end of the year.
However, implementing CAN (FD) controller and CAN transceivers is just one part of the story. Device (ECU) and network design rules, recommendations, and specifications are needed to make life easier for CAN users. CiA develops the CiA 601 series providing recommendations for node and network designs. CiA 601-2, recommendation for CAN controller host interfaces, is close to be released. The CiA 603 document is intended to harmonize the time stamping of Classical CAN and CAN FD messages.
SAE has developed the J2284-4 and J2284-5 recommended practices for passenger cars. Part 4 specifies a CAN line topology for 500 kbit/s (arbitration) and 2 Mbit/s (dataphase). Part 5 is suitable for dataphase bit-rates up to 5 Mbit/s and a point-to-point communication. These documents are guidelines for OEMs and Tier 1 supplier.
CiA works on the CiA 602 series for commercial vehicles and off-highway vehicles. Part 2 specifies the mapping of J1939 parameter groups to CAN FD frames. The network design including the physical layer is not yet finalized.
In general, the CiA technical groups need to know the requirements for the desired CAN FD networks – from members and non-members. Please feel free to contact us by email service(at)can-cia.org.
In the June issue we focus on CANopen. There are two articles about small drives from Faulhaber and Maxon Motor as well as an article about using CANopen instead of analog signals. But there are also other topics such as CAN FD. We report about flexible diagnosis for it, the new dynamic parameters of this standard, and also about the last CAN FD plugfest where robustness has been tested. Two other articles describe enabling IoT connectivity for CAN and CAN security with hidden key generation. Downlaod the full magazine to discover all articles.
If you are looking for CAN-related products, you could visit the CAN Newsletter Online and the CiA Product Guide. Both publications provide brief product information. The product guides are structured according to a nomenclature in order to make it as easy as possible to find the desired product information. The online magazine reports recently launched CAN products.
