Safe and low-cost operation of infrastructures in large, but also in small, buildings nowadays requires that the most important operational functions such as system control, air-conditioning, and lighting are running automatically. However, this also makes higher demands on the functions of the building installation, which can usually be met by conventional technology only with large expenditures. This is why building automation is increasingly using Ethernet-compatible bus systems, which execute the transmission of information between sensors and actuators, switches, and higher-ranking control systems.
