Abstract (en)
[origin: WO2020056701A1] A first safety control unit (20a) of a safety network of an elevator system, the first safety control unit (20a) is configured to determine a first plurality of safety input states of a plurality of the safety inputs (202a, 204a), receive a second plurality of safety input states via a digital communication module from a second safety control unit (20b; 20c) of the safety network, and determine a safety output state of at least one safety output (212a) in dependence on the first plurality of safety input states and in dependence on the second plurality of safety input states. The number of inputs and connection points towards an elevator controller system can be heavily reduced, which saves system wiring time and makes it easier to conduct maintenance of the system, so costs can be significantly reduced.
