The demands on wiring installation in buildings are getting tougher all the time as the technology itself advances. Electricians need to keep abreast of these developments. KNX installation technology expands upon conventional wiring and blazes a new trail, creating a full building management system. In addition to the normal wiring, a bus system is also required to allow for communication between end devices. All these devices are possessed of their own intelligence programmed via a PC. The system is decentralised and the PC is only used for programming the equipment.
