KNX is a standardized (EN 50090, ISO/IEC 14543), OSI-based network communications protocol for intelligent buildings. 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). The KNX standard is administered by the KNX Association. ==KNX protocol== The standard is based on the communication stack of EIB but enlarged with the physical layers, configuration modes and application experience of BatiBUS and EHS. KNX defines several physical communication media: * Twisted pair wiring (inherited from the BatiBUS and EIB Instabus standards) * Powerline networking (inherited from EIB and EHS - similar to that used by X10) * Radio (KNX-RF) * Infrared * Ethernet (also known as EIBnet/IP or KNXnet/IP) KNX is designed to be independent of any particular hardware platform. A KNX Device Network can be controlled by anything from an 8-bit microcontroller to a PC, according to the needs of a particular implementation. The most common form of installation is over twisted pair medium. KNX is approved as an open standard to: * International standard (ISO/IEC 14543-3) * Canadian standard (CSA-ISO/IEC 14543-3) * European Standard (CENELEC EN 50090 and CEN EN 13321-1) * China Guo Biao (GB/T 20965)〔Knx.org: (What ist KNX? )〕 KNX Association, as of 1 March 2014, had 339 members/manufacturers from 37 countries.〔Knx.org: (KNX Association Members )〕 Japan's Fujitsu General was enlisted as member number 300.〔Press Release: (Fujitsu General joins as KNX member No. 300! ) PDF 2012-11-01〕 The complete list can be found here at (knx.org ) The KNX Association has partnership agreements with more than 30,000 installer companies in 100 countries and more than 60 technical universities as well as over 150 training centres. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「KNX (standard)」の詳細全文を読む スポンサード リンク
