An automation network interconnects various devices within a building or plant on a local level. Usually, the automation network is designed as a physically wired network, for example as an Ethernet. However, it can also be a wireless or virtual network. The network connects devices, sensors and systems to enable automated processes in a building or within a plant. The goal of automation is to optimize processes. Data from monitoring is processed by the automation network to make data-based decisions and automate them in the next step. Thanks to the possibility of remote access, operators can conveniently control the systems at any time and from any location.A well-implemented automation network contributes to improved energy efficiency, comfort and safety for building users. It enables networked, intelligent building control and is an important basis for building automation.
