Abstract (en)
[origin: EP2022742A1] The system has a lift car (12) movable inside a lift shaft (11), and a decentralized control system including an evaluation unit (21) that is assigned to the lift car. The decentralized control system includes another evaluation unit (23) that is assigned to the lift shaft, where the two evaluation units are connected together by a bus connection (22). A signal transmission occurs over the bus connection under the utilization of a safety protocol such that a security-relevant data transmission is enabled between the evaluation units. Independent claims are also included for the following: (1) a method for controlling a lift system (2) a computer program with program code for performing a method for controlling a lift system.
