LonMark

LonMark is a global organization that aims to promote and standardize the use of Lon protocol, a device networking protocol used in the building automation and control industries. Founded in 1989 by David G. Stein, LonMark is an independent, non-profit trade association that represents over 200 member companies worldwide.

LonMark's primary goal is to provide a set of open, multi-vendor standards for the Lon protocol, allowing for interoperability and compatibility among devices from different manufacturers. The organization develops and publishes technical documents, such as the LonMark Interoperability Guidelines, which outline the rules and procedures for implementing the Lon protocol in a way that ensures seamless integration and operation.

LonMark's standards are based on the Lonworks SETP (Standardized Engineered Transmission Protocol) technology, which allows devices to communicate with each other using a standardized language. This enables devices from different manufacturers to talk to each other and exchange data, regardless of their brand or type.

LonMark also provides training and education programs for industry professionals, architects, engineers, and contractors, to help them understand the benefits and applications of the Lon protocol in building automation and control systems. The organization works closely with other industry organizations and standards bodies to promote the adoption of the Lon protocol and ensure its continued relevance and innovation.

Today, LonMark is a recognized leader in the building automation and control industries, with a global presence and a long history of successful participation in industry forums and standards development efforts.
