Standards

ISO/IEC series of standards

LonWorks control networking technologies have been approved national standards in Europe (EN 14908), America (ANSI/CEA 709), and China (GB/Z 20177) for several years.  As a natural course of standards development, the standards were presented to ISO/IEC for inclusion in their standards portfolio.  The EN 14908 series of standards was submitted for international standardization to ISO and IEC’s Joint Technical Committee 1 (JTC 1) by the US InterNational Committee for Information Technology Standards (INCITS) in 2007.

What are the national standards?

The following are the national standards (USA, Europe, and China, respectively) for the protocol and various transfer media.
