LonMark International has announced that its product catalogue has reached the 500 certified product milestone, reflecting an increased demand for open, interoperable devices and systems. When a product carries the LonMark logo, the product has been designed and tested to interoperate over a LonWorks® network.

Since its inception in 1994, and after the announcement of a new corporate structure in 2003, LonMark International has been a driving force in the establishment of interoperable guidelines for building, industrial and utility automation. LonMark membership is open to any manufacturer or end-user committed to the development and use of open products using ANSI/EIA 709 and related standards.
