A BUS or also bus system is a transmission line via which data is transmitted between different devices and components. The BUS communication standard defines the rules, protocols and technical specifications for transmission via the BUS. It thus defines parameters such as the coding, reception and interpretation of the data. This makes it possible to send status information and commands.In building operation, the BUS communication standard is a specific standard that allows the different trades to communicate with each other. Examples of such standards are KNX, LonWorks, Modbus or DALI, all of which have different characteristics and areas of application. Thanks to the common communication via the BUS, it is possible, for example, to control lighting, ventilation, air conditioning, security systems and other processes across systems. Automation is almost unthinkable without a BUS communication standard. The standard also simplifies the integration of new components into an existing control system.
