LonWorks

LonWorks is not just a protocol or physical layer for communication but an exclusively designed networking technology platform to install, maintain, monitor and sense various automation and control applications. Essentially LonWorks was established for a range of automation functions within buildings such as lighting and HVAC. Invented by Echelon Corporation, the fundamental communications platform, twisted pair signaling technology, power line signaling technology, and IP tunneling method constitutes a global standard documented ISO/IEC 14908.                      
                     

LonWorks Protocol

A set of services is offered by the LonWorks Protocol that enables all devices in the network to transmit and receive messages to and from other devices via their application program— requiring no acquaintances with network topology or the other devices' names, addresses, or functions. Besides, LonWorks Protocol can be made to deliver authentic, high priority messages within delimited transaction times. Moreover Network management services allow remote network management tool’s interaction with devices over the network; making them capable to reconfigure network addresses and parameters, download application programs, report network problems and Start/stop/reset device application programs. Consequently it’s relatively easy to employ LonWorks network over any medium, including power line, twisted pair, radio frequency (RF), infrared (IR), coaxial cable, and fiber optics.
