KNX National Group – India Association, had a KNX Training Workshop in Mumbai on the 16 & 17th Of September 2016, for which we were invited by Mr. Bhavesh Doshi, who is the Secretary of the KNX National Group – India.  Mr. Christian Stahn, Marketing – KNX(Beligium) was at hand to give us an introduction via slide shows of what KNX is all about and how it can be used by system integrators to get the best results for running applications for home and building controls. This was followed by a presentation given by Mr. Bhavesh Doshi, Secretary of the KNX National Group – India, of how he was part of the group who undertook the lighting controls and monitoring systems set-up of the Delhi International Airport Limited (DIAL), which at that point of time was the 5th largest lighting control systems in the world.

What was extremely noteworthy was that with KNX being part of the home and building control, one has the ability to ensure energy savings of between 40 to 60 percent for shutter, single room, lighting and ventilation control!

KNX National Group – India Association also conducted a lucky draw for system integrator’s attending the workshop, to win some of the KNX software tools.

Some more info on KNX:

KNX Association is the creator and owner of the KNX technology – the worldwide STANDARD for all applications in home and building control, ranging from lighting and shutter control to various security systems, heating, ventilation, air conditioning, monitoring, alarming, water control, energy management, metering as well as household appliances, audio and lots more. The technology can be used in new as well as in existing home and buildings. For members of the KNX Association the system is royalty-free, moreover can be implemented on any processor platform. All products bearing the KNX logo are certified in order to guarantee system compatibility, interworking and interoperability.

KNX is the only global standard for home and building control with –

A single, manufacturer independent design and commissioning tool (ETS).

A complete set of supported communication media (TP, PL, RF and IP).

A complete set of supported configuration modes (system and easy mode).

KNX is approved as European Standard (CENELEC EN 50090 and CEN EN 13321-1). International Standard (ISO/IEC 14543-3). Chinese Standard (GB/T 20965). US Standard (ANSI/ASHRAE 135).

This standard is based upon more than 24 years of experience in the market including its predecessors, EIB, EHS and BatiBUS.

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). The KNX standard is administered by the KNX Association. 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.

All the devices for a KNX installation are connected together by a two wire bus (the most common form of installation), thus allowing them to exchange data. The function of the individual bus devices is determined by their project planning, which can be changed and adapted at any time.

Sensors (e.g. push buttons, wind-, temperature-, movement-sensors)

Actuators (dimming units, electrical heating valves, displays)

System devices and components (e.g. Line-Couplers, Backbone-Couplers)

Sensors are the starting point for every action, because they gather information and send it on the bus as a data telegram. This can be information about room temperatures, movements, wind measurements or manually input instructions (Push buttons). Sensors are selected depending on the required application. Actuators receive data telegrams which are then converted into actions. This can include controlling blinds, dimming lights or controlling heating and air conditioning systems. Actuators are also selected depending on the required application and consist of a bus coupler and an application module with the corresponding application program. The application program is loaded into the devices together with the project design and commissioning software via a system component called interface (either serial or USB interface) connected to the PC and the bus. The two-wire installation bus is routed in parallel to the 230 V electrical power supply connects all devices and systems of the household technology together, and transmits all the control signals. It looks the same as the DALI protocol bus.
