No. 12 - August 22, 2025

A word from the CiA Managing Director

In November, CiA organizes three one-day technology days in Beijing, Shanghai, and Shenzhen. Several CiA members provide presentations about CAN XL data link and physical layers as well as about the CAN XL ecosystem, including tools and add-on functions such as security and functional safety. The detailed program will be available soon on the CiA website. Simultaneous translations into Chinese language are planned.

These three CiA technology days address mainly the automotive industry, but engineers from other application fields are welcome, too. CAN XL with data field length of up to 2024 byte is suitable for low-end backbone networking and can be used as a reliable and robust lower OSI (Open Systems Interconnection) layer approach running higher Ethernet-based protocols.

Because the number of seats is limited, I recommend to register as early as possible. These Chinese technology days are a unique possibility to meet many of the European and American CAN XL parents and early adopters.

Currently, the CANsec specification (CiA 613 series) is under development. I expect a technical mature CiA first work draft within the next two months. The updated ISO 11898-2 standard – includes the CAN SIC XL physical medium attachment specification – has been submitted for balloting. The ISO conformance test plans for the CAN XL data link layer and the CAN SIC XL physical layer are in preparation. They have been partly predeveloped in CiA technical groups.

The CAN XL ecosystem with first CAN XL protocol controllers and CAN SIC XL transceiver chips is growing. It also covers interface and evaluation boards as well as development and diagnostic tools. Several oscilloscope vendors support CAN XL. A list of vendors and suppliers is available on the CiA website.

Review of CiA 102 and CiA 103

CiA 102 (CAN physical layer for industrial applications) and CiA 103 (Intrinsically-safe CAN device interface) technical documents are in revision. Therefore, CiA calls for comments by August 30, 2025. The CiA 102 document is intended to be released as a technical report. It provides recommendations for designing CAN CC (classic) networks using CAN HS (high-speed) transceivers as specified in ISO 11898-2. The CiA 103 document is to be published as a technical report, too. It provides guidelines to develop an intrinsically-safe device interface, to be used, for example, in explosive environments. CiA technical reports are downloadable free of charge from the CiA website. Normally, they contain recommendations and permissions, but no requirements.

CiA 443 version 4.1.0 released

The CANopen profile for SIIS level-2 devices (CiA 443) has been revised and released as a draft specification proposal (DSP), version 4.1.0. It specifies so-called subsea (Christmas) trees comprising a host controller as well as sensors, meters, batteries, and actuators (valves/drives). The main technical change is the introduction of electric actuators (object 6520h). Additionally, editorial improvements have been made.

CiA glossary updated

CiA has revised and updated its glossary of term definitions used in CiA technical documents. Especially, new terms related to CAN XL have been introduced. Terms related to CAN CC (classic), CAN FD, and CAN FD light were updated.

DIS ballot on ISO 11898-2 in progress

ISO calls for comments and votes on the 4th edition of ISO 11898-2 (High-speed physical medium access sublayer). The current 3rd edition from 2024 contains some inconsistencies and editorial weaknesses, which needs to be fixed. The standard covers CAN HS, the CAN FD, CAN SIC, and CAN SIC-XL transceivers. It also specifies low-power modes and selective wake-up functionalities. ISO P-members are invited to submit comments and to vote. Ballot period terminates end of October, depending on deadlines given by national standardization bodies. The deadline for DIN experts is October 30, 2025.

CAN Newsletter magazine


As usual, this issue contains technical in-depth articles, product news, and reports. One of the reports informs about the increasing acceptance of CANopen Safety in construction machinery and other off-road vehicles.
