Nuremberg, Germany, 2026-04-02. The four-part CiA 417 application profile specification for lift control systems has been revised. CiA has released a new version, which introduces a power supply unit. Other units have been functionally extended, adding new parameters and specifying additional PDOs (process data objects). All four parts of the CANopen Lift specification have been editorially improved. This includes clarifications, improvements regarding understandability, and restructuring of subclauses.
CANopen Lift is a widely used application profile by the nonprofit CiA (CAN in Automation) association with more than 700 members. It specifies control functions as well as CANopen interfaces for sensors (e.g., input panels) and actuators (e.g., car drives and door units) used in elevators, including freight lifts. The first version was released in 2003, and the version 2.0.0 was published in 2011 (can be downloaded free of charge from the CiA website). The currently updated draft specification proposals (DSPs version 2.4.0) are available only for CiA members.
“CANopen Lift is an application profile, which enables the development of interoperable products,” explained Holger Zeltwanger, CiA Managing Director. “This unburdens the system developer from complex programming and configuration tasks; some configuration is required for optional functions.” CANopen Lift devices are offered by more than 60 CiA member companies.
