What ist KNX?
We can give a quick and easy answer, as this is a technology that is supported by more than 265 manufacturing companies worldwide, with an expertise in building automations and with more than 30,000 certified members around the world, a palette of devices composed by more than 7000 product groups, a technological tool that breaks any previous technological limitations.
If someone tried to design a response on the basis of some keywods, he could write words like:
Safety, Comfort, Functionality, Energy Management, Communications, Networking, Full control of Electromechanical Installations, Scalability, Flexibility, Manufacturer Independence, Open Communication Protocol, long-life buildings and many other.
So KNX is a system with electrical installations and mechanical installations so they can coexist in one building. Here are devices from more than 265 manufacturers which can communicate with each other, just using one technology! All systems are in full cooperation with each other in one project!
If it is so, it looks like some kind of building ecosystem, a holistic approach to building more as a living entity that exists, lives, breathes, a unifying design philosophy of all systems that exist in one building and much more...
1 KNX STANDARD
1.1 KNX – A brief outline
Very high demands placed on flexibility, security and convenience of electrical installations led to building automation systems. Whether in a single-family house or in an commercial building, the demand for comfort and versatility in the management of lighting, shutters, air-conditioning and access control systems was and is still growing. At the same time, the efficient use of energy is very important for all segments.
More convenience and safety coupled with lower energy consumption can however only be achieved by intelligent control and monitoring of all products involved. This however implies more wiring, running from the sensors and actuators to the control and monitoring centers. Such a mass of wiring in turn means higher design and installation effort, increased fire risk and soaring costs. More convenience, more safety, higher energy savings can deliver only building management systems and one of them is KNX system.
KNX is the world's only open standard for home & building automations. While the KNX market is still dominated by EIB, twisted pair with PC configuration, the KNX standard currently offers a wide variety of media and configuration modes. KNX now covers the full range of in-house communication options, including twisted pair, powerline, radio frequency and even Ethernet media. Especially the combination of various media has made it possible to implement new solutions for building powerful networks. For example, radio frequency and twisted pair or twisted pair and IP can be incorporated in a single installation. If you add RS-232 and other interfaces that you know that sky is your limit in this integration.
1.2 KNX – the beginning
Chapter – TP1 Cable Lengths
