Elevator system

A method for setting up an elevator safety system, the elevator safety system comprising an elevator system component, an actuator for causing a change in a status of the elevator system component, a data bus, a safety controller configured to communicate via the data bus, a sensor configured to indicate the change in the status of the elevator system component, and an elevator system node associated with the sensor and configured to communicate via the data bus, wherein the elevator system node is configured to communicate the change in the status of the elevator system component to the safety controller via the data bus, the method comprising:

• causing, by the actuator, the change in the status of the elevator system component,
• detecting, with the sensor, the change in the status of the elevator system component, the detecting including generating, at the sensor, information indicating the change in the status of the elevator system component,
• communicating, with the elevator system node, the information indicating the change in the status of the elevator system component to the safety controller via the data bus, and
• linking, in a memory of the safety controller and subsequently to the communicating the information indicating the change in the status of the elevator system component to the safety controller, an address associated with the elevator system node with an identifier of the elevator system component.
