KNX system description The KNX system is a flexible, upwardly compatible installation bus system (formerly EIB = European Installation Bus) for use in building system technology. It is specially tailored to special requirements in terms of comfort, the possibility of flexible use of space, the combination of central and decentralized control, the intelligent linking of trades and systems, communication options, environmental compatibility, energy and operating cost minimization as well as the display, reporting and operation functions , monitoring and detecting. Due to its decentralized structure, it enables building-specific operational management in residential and functional buildings, regardless of the system size. The use of commercially available circuit distributors and installation boxes is particularly advantageous. All bus users are connected via a bus line (e.g. JY(St)Y 2x2x0.8) that conforms to the KNX guidelines (Konnex Association). Since the bus line, according to DIN VDE 0100, can be laid directly next to high-voltage lines, the line routing is greatly simplified. Compared to public telecommunications systems, the bus system with all its components should be treated like a high-voltage system. As with the high-voltage installation, the cable routing may be star-shaped or tree-shaped. A combination of the different cable routings is generally permitted. Wiring is done using two-wire technology, with the cores colored red (for +) and black (for -) representing the preferred cores. The cores with the colors white and yellow serve as reserve. The participants are supplied with the bus voltage (safety extra-low voltage SELV 30 V DC) via the bus cable. At the same time, it serves to transmit the information that is exchanged between the bus participants. A terminating resistor is not required for the bus line. The smallest unit in the KNX system is a participant. Each participant consists of an application module (AM) and a bus coupler (BA). AM and BA are connected to each other via the user interface (AST). Up to 64 participants can be connected to one line. Twelve lines can be connected to each other via line couplers and thus combined into one area. Up to 15 of these areas can be connected to each other via area couplers. Configuration, parameterization, commissioning and diagnostics are carried out with the ETS (EIB tool software). The system documentation is also created with the ETS. A unique physical address is assigned to each participant as part of the configuration. This consists of the number of the area, the line and the subscriber within the line. During commissioning, this physical address is first loaded into the BA. To do this, the PC is connected to the bus at any point in the system via a data interface (USB). The programming of all BA of a KNX system with the assigned applications from the manufacturer database is based on the physical addresses. Each BA contains an EEPROM in which the physical address and the application are stored. In this way, the KNX system is protected against data loss in the event of a power failure. The following conditions apply to the installation of the KNX system: - The total length of all cables laid in a bus line must not exceed a length of 1000 m! - The maximum length between two bus devices is 700 m! - The maximum cable length between the power supply (including choke) and each bus participant must not exceed 350 m! - In order to avoid EMC interference caused by overvoltage, make sure that the bus line does not form a closed loop at any point in the system! - The project planning and parameterization as well as the commissioning and diagnostics of a KNX bus system requires precise product knowledge in relation to the functionality of the system. For this reason, all of the above work may only be carried out by trained persons.
