First CANopen FD devices were exhibited at the SPS IPC Drives 2018. CiA made some progress in CANopen FD specifications, which will continue next year. CiA has made a video explaining briefly the benefits of CANopen FD.
DIN 4630 – More than just the link to “clouds”
This CAN network approach specified in DIN 4630 covers also the control of commercial vehicle bodies. This includes applications such as cranes, tail-lifts, refrigerators, etc. For more information, please contact CiA office.
Next generation CAN data link layer
CiA will establish a new SIG specifying the next generation CAN data link layer as proposed by VW. This approach will provide payloads up to 4 KiB. The SIG will be inaugurated in December. For more information, please contact CiA office.
Re-organized Interest Groups
The CiA Technical Committee has established new Interest Groups (IG) and renamed some already existing groups. The IGs are described briefly here.
CiA 401 for CANopen FD
CiA office prepares a CiA 401 PDO mapping for CANopen FD. First members like to show at SPS IPC Drives prototype implementations. The document CiA 401-2 is intended to be released beginning of next year.
SAE J1939-22
SAE develops the J1939-22 document, which specifies an application layer for CAN FD. CiA has submitted its multi-PDU approach (CiA 602-2) to be integrated into the SAE document.
CANopen FD meeting
The CANopen SIG application layer has scheduled a two-day meeting (2018-10-22/23) to harmonize additional CANopen FD related specifications (EDS, test plan, and LSS). All members are invited to participate in this meeting.
CiA 447 updated
The CANopen specification for open networks in passenger cars has been improved. CiA 447-2 and CiA 447-3 version 2.1.3 introduces some new parameter for the virtual devices information signaler and switch keypad.
SAE J1939DA updated
As usual, the SAE J1939 committee has updated the digital annex. Since the beginning of August, the J1939DA is available by SAE. It contains PG (parameter group) and SP (suspect parameter) specifications, for example.
ISO 16845-2:2018 released
ISO has released the test plan for the high-speed MAU compliant to ISO 11898-2:2016. The dynamic test cases include functions specified in ISO 11898-1:2015 for implementations with partial wake-up functions.
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 one 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.
