Le protocole KNX est un protocole à logique répartie. Contrairement à d'autres protocoles d'automatismes, celui-ci ne fonctionne pas en mode maître/esclave, chaque automate étant indépendant des autres.
KNX is a standardized (EN 50090, ISO/IEC 14543), OSI-based network communications protocol for building automation. KNX is the successor to, and convergence of, three previous standards: the European Home Systems Protocol (EHS), BatiBUS, and the European Installation Bus (EIB or Instabus).

It's an international protocol to link between the electric parts and automation modules like modebus ,canbus , smart but RS385
KNX is a network communication protocol that is used to put the intelligence into intelligent buildings. It enables the integration and programming of a range of products from a range of manufacturers using a single software tool called ETS. This standard is based upon more than years of experience in the market, amongst others with predecessor systems to KNX: EIB, EHS and BatiBUS. Via the KNX medium to which all KNX products/bus devices are connected (twisted pair, radio frequency, power line or IP/Ethernet), they are able to exchange information. Bus devices can either be sensors or actuators needed for the control of building management equipment such as: lighting, blinds / shutters, security systems, energy management, heating, ventilation and air-conditioning systems, signalling and monitoring systems, interfaces to service and building control systems, remote control, metering, audio / video control, white goods, etc. All these functions can be controlled, monitored and signalled via a uniform system without the need for extra control centres.
