CANopen is an open communication standard which is also employed for different lift components. The uniform application profile allows, for example, the combination of appropriate controller systems with fixtures and their components as well as with further components of the lift.
In comparison to conventional wiring, with CANopen only a few lines are needed. Further positive aspects are the individual configuration, the easy upgrading of the system as well as the simple diagnostics and troubleshooting in case of failure. In every fixture, the so called nodes serve as interface between the components and the terminal box respectively controller.
