Counterpart to a sensor. Converts electrical signals of a control into (mostly) mechanical action such as pressure and flow, for example.

Internationally standardized, non-proprietary standard for data communication in building automation systems (ISO 16484-5).

Unit of speed for serial data transfer. Example: 9600 Baud = 9600 bit/s.

Smallest information unit, recognises only two statuses: Zero (0) or One (1); see also Byte

Pipeline system for the exchange of data between several hardware components.

Information unit, comprised of 8 bits

Serial bus system originally developed for the automobile industry, which, in the meantime, is used frequently in automation technology.

Extension of the CAN standard to include application-related definitions, electronic data sheet files and profiles. Makes system integration easier and was developed by the CAN in Automation (CiA) association.

Integrated consideration of buildings, real estate and operational sequences, with the objective of sustainably lowering the operating and administrative costs, to make the fixed costs more flexible, to secure the technical availability of the systems and to retain the value of the buildings and systems long-term.

Device which converts the protocols of different bus systems, thereby making it possible to connect different networks. Data to be transmitted must be defined individually for each application (see also: router).
