LCN was developed to achieve the following goals:
  • To simplify the design and planing of building control and automation processes
  • To simplify installation and expansion procedures
  • To enable the system to use only standard wiring materials and methods
  • To enable ordinary trained electricians to easily program the system
  • To make the system cost effective and maintenance free
Design with LCN is simple. Going off from the number of lighting fixtures and electrical devices in a building and how they should be controled, the number of intelligent LCN modules are calculated based on their outputs capacity. The only limitation that should be kept in mind is the max number 250 modules that can be directly connected on a single bus segment. In large installations, bus segments can be connected together using bus couplers. A max number of 120 segments can be directly connected together, thus allowing 30,000 modules to communicate with each other in one single installation. In reality, 250 modules in a bus segment is such a large number that is almost never be needed. Usually a good topology layout in a large installation will assign a segment to a physical area such as one floor in a multi-story building or the landscaped area. In a single family house, typically fewer than 10 modules in whole installation would provide sufficient basic automation functionalities.
Installation can also be centralized by using rail-mount modules such as LCN-SH which can then be supplemented with relais block LCN-R8H to drive high load devices.

The followings are only a few characteristics of LCN technology that allow effective design of a building control and automation system:

  • Designers get a large combination of possibilities resulting from a small set of sensors and actors, allowing lot of flexibility to reach to goal of the building design.
  • Only a small set of easy rules that designers need to follow to construct a LCN network.
  • It is easy to design a network topology that is well structured.
  • The resulting network is cost effective and maintenance free.
  • The technology enables a high performance network that can handle complex critical functions in even largest installation in real-time. Designers can be confident that network operations are reliable. No central control unit means that failure of a module can affect only a small area and can be easily identified and contained.
  • The technology allows the network to easily grow over the time to either accomodate new physical space or more complex functionality
