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.

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.

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.
