CiA 417: CANopen application profile for lift control systems

The CiA 417 CANopen application profile describes virtual lift control devices as well as a default communication behavior with pre-defined PDO linking supporting broadcast and peer-to-peer communication. It supports multiple lift control system. The specification describes the default PDO communication of a control system for up to eight lifts with up to 254 floors each. The default communication can be changed by means of configuration.

All virtual devices implement mandatory functions as well as optional behavior. The virtual device concept allows the introduction of user-transparent gateways. The gateway may implement up to 254 virtual devices on each side and represent them to the other interface.
