A word from the CiA Managing Director

CiA presented on its Embedded World booth in Nuremberg three CAN FD light demonstrators. The demonstrator by Bosch showed a network connecting responder nodes based on the company’s CAN FD light IP cores running at 8 Mbit/s. The nodes used CAN SIC transceivers. STMicroelectronics demonstrated a rear light application based on the company’s L99DLH32 and L99LDLL16 LED driver chips. The third demonstrator by Vector showcased the configuration of CAN FD light networks by means of tools.
Originally, the CAN FD light specification has been developed within CiA. In the meantime, the related CiA 604-1 document has been submitted to ISO and is now the base of an ISO 11898-1:2024 annex. The corresponding CiA document has been withdrawn.
Since some time, CiA develops a CAN FD light system design recommendation (CiA 604-3). A work draft is already available for CiA members. Recently, CiA has started a CAN FD light high bit-rate specification. Additionally, CiA is working on ISO 11898-1:2024 clarifications regarding CAN FD light. They will be introduced into the next edition of ISO 11898-1. The ISO 16845-1 conformance test plan will reference some of these clarifications. The conformance test plan of the CAN FD light high bit rate approach will be specified in CiA 604-11, which will be submitted later to ISO.
The improved CAN FD light approach enables bit rates up to 8 Mbit/s, when using CAN SIC transceivers as standardized in ISO 11898-2:2024. The high bit rate approach has also some impacts on the CAN FD light commander nodes, which are also covered by the CiA documents.

Bauma 2025
The CiA joint booth with nine sub-exhibitors was well visited. Among the main topics discussed were functional safety and cybersecurity. Therefore, the migration to CAN FD, CANopen FD, and SAE J1939-22 was a topic, as well. As a follow-up, CiA has scheduled a four-hour online technology day (CAN in mobile machines) end of April. The 4-h event was recorded and will be available on CiA’s YouTube channel (see link in the footer of this email), soon.
CiA online in-house seminars
Agendas of CiA online in-house seminars are customized. The experienced CiA trainers hold the seminars in English or German language. The seminar can be split into parts, if desired. CiA recommends a minimum length of two hours and a maximum length of four hours (including breaks). CiA does not provide hands-on trainings, because the seminar contents are product- and company-independent. The in-house seminars can address development engineers, decision makers, sales and marketing staff as well as service technicians.
CAN Newsletter magazine
The March issue reported about radar sensors with CAN interfaces by Pepperl+Fuchs and Turck. In the meantime, CiA has called for experts to develop a generic profile for radar sensors and parameter mappings to CANopen and J1939. Standardized profiles simplify system integration. The inaugural meeting of the CiA SIG radar sensors was held a few days ago. A detailed report will be published in the June issue of the CAN Newsletter magazine.
CiA 601-2: CAN FD protocol controller interface
IG (interest group) CAN lower layers has withdrawn the CiA 601-2 specification. The content was described in a way that misunderstandings and misinterpretations were possible. This means, this CiA document needs to be revised. Because of the mentioned reasons, it is not more available. The IG decided not to maintain the document, anymore.
Embedded World China: Restructured and postponed
The trade show Embedded World China has been originally scheduled to take place in Shanghai (China) on June 11 to 13, 2025. Now, it has been restructured and postponed to October 16 to 17, 2025. The organizer has decided to restructure the event into a more focused format – the Embedded World China Conference. For further event details, please visit the official organizer website.
CiA is not able to participate in the conference, because the Interlift trade show is scheduled on the same time.
