Abstract: According to an aspect, there is provided a method for determining a sequence of bus nodes in a multi-drop communication bus. The method includes for each bus node: sending a request to the bus node using an bus node physical identifier to set the bus node to a loopback mode; transmitting at least one signal to the bus node via the multi-drop communication bus; receiving from the bus node a loopback signal caused by the at least one signal; and measuring a roundtrip delay between the at least one signal and the loopback response signal. The method further includes solving the physical order of the bus nodes in the multi-drop communication bus based on the roundtrip delays.

Abstract: Elevator components can be equipped with an electronic information plate. The electronic information plates are associated with a particular electronic information plate that can store different properties of the associated component. The content of each electronic information plate is read manually or automatically and transmitted to a controller. The controller analyzes the received content and launches a predetermined action if the content indicates a need for maintenance.

Abstract: The invention relates to a method for verifying speed data of an elevator car for overspeed monitoring of the elevator car. The method comprising obtaining at least one continuous speed data of the elevator car at two channels; obtaining a zone speed data of the elevator car within at least one zone of an elevator shaft at two channels, generating a two-channel verified speed information by comparing the said at least one continuous speed data to the zone speed data at least at one channel; generating a control signal, if the comparison indicates a mismatch at least at one channel; and if the comparison indicates a match at each of the at least one channel in which the comparison is provided; the method further comprising comparing the verified speed information at each channel between each other; and generating the control signal, if the reciprocal comparison indicates a mismatch. The invention also relates to a safety control unit and an elevator system performing at least partly the method.
