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.

The ISO/IEC standards

The Standards are available through ISO’s standards catalogue at the following links:

  • ISO/IEC 14908-1 (Protocol): Information technology — Control network protocol — Part 1: Protocol stack
  • ISO/IEC 14908-2 (Twisted-pair media): Information technology — Control network protocol — Part 2: Twisted pair communication
  • ISO/IEC 14908-3 (Powerline media): Information technology — Control network protocol — Part 3: Power line channel specification
  • ISO/IEC 14908-4 (IP Tunnelling of the protocol): Information technology — Control network protocol — Part 4: IP communication

What are the national standards?
