CANopen in rolling stock

The IEC 61375-3-3 standard provides the general requirements for classic CANopen networks in train consists.

Additionally, CiA has specified and released CiA-internally several CANopen application profiles for locomotives and coaches. This includes specifications for controlling diesel engines, doors, lighting, etc. They are based on UIC leaflets. These profiles need to be updated regarding new application features. Additionally, CANopen FD can be suitable for some rolling stock applications. CAN XL can also be of interest.

This is why CiA has scheduled several meetings to initiate discussions about the usage of CAN networks in rail vehicles. For those parties, who like to get an overview of what has been developed so far, there is the CiA webinar scheduled on September 8. It provides basic information on possible CiA specification improvements. If you would like to discuss these topics personally, you can meet CiA staff on the Innotrans trade show at the CiA booth in Berlin, at the end of September. CiA has also scheduled an online workshop on September 30. The participation is limited to members and invited guests. This workshop is intended to discuss in detail the work plans of the Special Interest Group (SIG) rail vehicles, which is currently in dormant state. This includes the identification of new feature requests and improvement of existing technical CiA documents. Interested parties may contact the CiA office.
