Digital signal transmission system for building systems engineering

摘要

The invention relates to a digital signal transmission system for use in building systems engineering for information messages. User devices with function types such as actuator and/or sensor and/or evaluation can be connected to a bus (2) using coupling elements (1) with interfaces. According to the invention, the coupling element (1) is provided with a number of permanent functions for user devices, such as switching, and designated connecting points (8) for devices with operating surfaces. The coupling element is also provided with a number of connecting points (9) for connecting modules (10) with function types for user devices, these modules (10) being provided with an actuator function and/or sensor function and/or evaluation function, telephone function or television function and/or configured for connecting devices with certain function types. The coupling element (1) carries and distributes energy for the user devices or user functions and information, and is configured for individually defining functions in user devices and/or modules (10) for user devices using bus-end information messages.
