ISO/IEC standardization for LonWorksR Control Networks

San Jose, CA, U.S.A. — (METERING.COM) — December 8, 2008 – The technologies underlying Echelon Corporation’s LonWorks platform have been approved as a global control standard by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), the company has announced.

Tens of millions of LonWorks based devices have been installed in a wide variety of applications, including buildings, factories, trains, electric utilities, coal mines, and homes around the world.  

ISO/IEC standardization represents the highest level of standardization attainable and reflects the market support and adoption of the LonWorks platform by thousands of companies worldwide. The acceptance of the protocol and key signaling technologies underlying LonWorks networks as ISO/IEC standards helps assure continued adoption of the platform, especially in the growing market for energy demand management in commercial buildings and homes.

Ken Oshman, Echelon’s CEO and chairman said, "Many of us are unaware that we experience LonWorks control applications every day, as they are largely invisible. They provide improved safety, convenience, and comfort while improving energy efficiency."

Some of the world’s most notable energy and control applications are built using the LonWorks platform including Enel’s AMI  system in Italy, the City of Oslo’s managed street lighting system that reduces lighting energy use by 40%, and Duke Energy’s "Utility of the Future" AMI pilot.

The ISO/IEC standards for the LonWorks platform are formally known as:

  • ISO/IEC 14908-1: Communication protocol
  • ISO/IEC 14908-2: Power line signaling technology
  • ISO/IEC 14908-3: Twisted pair wire signaling technology
  • ISO/IEC 14908-4: IP compatibility (tunneling) technology

Previously these technologies were standardized in Europe as EN 14908-1, 2, 3, and 4, in China as GB/T 20299.4-2006 and GB/Z 20177.1, 2, 3, 4-2006, and in the United States as ANSI/CEA 709.1, .2, and .3 and ANSI/CEA-852.

Since 1999, the underlying protocol, twisted pair, and power line signaling technology for the LonWorks control networking platform have been known collectively as the ANSI/CEA 709 family of standards. Subsequently, ANSI/CEA-852 was ratified to add the use of the Internet Protocol (IP) as a transport medium for the LonWorks platform.
