New CiA 454 specifications

The CiA 454 set of documents specifies the CANopen application profile for energy management systems (EMS). It can be used to control energy sources and energy consumers. This includes light electric vehicles such as pedelecs and e-scooters. It is also suitable for stationary applications.

Part 3 (PDO communication) has been updated. Part 7 (drive control unit) is released for the first time as well as part 9 (human machine interfaces). All three documents are in DSP (draft specification proposal) status meaning they are only accessible for CiA members. Normally after one year, they are reviewed and published as draft specification (DS), which can be purchased also by non-members.

SIG electromagnetic compatibility (EMC)

The SIG EMC has started to develop the CiA 120 document, which specifies the EMC evaluation of CAN SIC and CAN XL SIC transceivers. It is intended to submit the related CiA document to IEC for international standardization in the IEC 62228 series. This SIG reports to the IG (interest group) lower layers.

Visiting CiA members and non-members online
