Abstract: A safety system for a building-related passenger transport system includes a safety unit for receiving safety-relevant signals from components of the passenger transport system and for triggering a safety measure, and an updating unit for receiving updated software via an external interface and for transmitting the updated software to the safety unit via an internal interface.

Abstract: A method for operating an elevator system includes a trusted device that creates an authentication data packet having a unique, periodically changing code based on the current time. A mobile device sends a mobile request message to a server including the request for the operation of the elevator system and the authentication data packet. A server verifies the authenticity of the mobile request message based on the authentication data packet included in the mobile request message and, after the authentication data packet has been verified, sends an instruction message to the elevator controller.

Abstract: An aligning device for aligning a guide rail of an elevator system has lower and upper rail bracket parts and at least two movement elements. The lower rail bracket part is fixed to an elevator shaft wall and the upper rail bracket part holds a guide rail. The lower and upper rail bracket parts each have a connecting region for fixing to one another. The movement elements move the lower rail bracket part relative to the upper rail bracket part. Each of the movement elements interacts with both of the connecting regions of the rail bracket parts. Each of the movement elements is rotatable about an axis of rotation and interacts, eccentrically with respect to the axis of rotation, with at least one of the rail bracket parts so as to abut laterally opposite contact surfaces of this rail bracket part.

Abstract: A method and a data network for communicating data content, particularly useful in an elevator system, includes a master unit and a plurality of slave units that are connected to one another via data communication paths to exchange data telegrams having a large number of bits between one another. The master unit and the slave units are connected in series to form a chain via the data communication paths wherein a data telegram is transmitted from the master unit to a last slave unit on an outward data path. The last slave unit initiates a data return path by returning the data telegram to the master unit. The data telegram is modified by the slave units exclusively during the data return path and at least one slave unit begins to compile information requested by the master unit immediately after receiving and evaluating the data telegram.

Abstract: A control system for an elevator is separated into a first assembly allocated outside and a second assembly allocated inside an elevator shaft. The first assembly includes a power switch for turning on/off the control system, a light switch for switching a light inside the shaft, a safety unit for protecting electrical safety of the control system, a communication unit for data communication with the elevator and/or an external communication device, and a bypass device for bypassing a safety chain of the elevator. The second assembly includes a power supply system for driving the elevator and/or for the safety chain, a monitoring system for monitoring the safety chain, a drive control unit for a drive motor, and a processor for data processing of the control system. The first assembly and the second assembly can communicate with each other and be connected respectively as segments into the safety chain.

Abstract: A method for checking the status of field devices of a building-associated installation for transporting people includes the steps of: sending a command block of a status telegram from a monitoring unit via a series bus to a plurality of field devices; supplementing the status telegram by the field devices that are addressed by the command block; receiving the data block supplemented by the addressed field devices by the monitoring unit; and evaluating the status values in the supplemented data block by the monitoring unit.

Abstract: A method for communication in a network, in particular for communication in an electrical low voltage network, transmits a status check from a master to a plurality of slaves in several network paths. A slave that cannot be directly accessed by the master, such as an additionally installed salve, is included in the network with the help of a neighboring slave. The neighboring slave is used as a router slave for the slave that cannot be directly accessed. For this purpose, a network management software for the master is provided with a software module for assigning at least one router slave to each slave. Each slave is assigned a corresponding software module to identify a neighboring slave as a potential router slave. A network for communication is also provided.
