SAN JOSE, Calif. - LonMark International has announced the release of Version 3.4 of the LonMark Interoperability Guidelines, designed to make it easier to install open, interoperable devices. The guidelines include support for self-installed devices and networks, further extending the reach of LonMark certification into consumer products, industrial automation, and other machine-to-machine (M2M) applications. Further enhancements have been made to improve device installation with network tools, making it easier for installers and integrators to create networks of open devices and systems, says the organization.

The LonMark Interoperability Guidelines provide manufacturers with details on how to design open, interoperable products based on the LonWorks® networking platform. Nearly 700 products have been tested and certified as compliant to the LonMark Interoperability Guidelines.

Recognizing the need for small, simple networks to self-install without the use of installation tools, Version 3.4 includes a newly developed Interoperable Self-Installation (ISI) protocol. Devices using the optional ISI protocol install themselves - either automatically or with the use of a pushbutton. Products tested to conform to the ISI protocol will be eligible to carry the new LonMark ISI logo to help users distinguish products certified to the LonWorks protocol.

Simplifying development, installation, and maintenance of certified products has been a priority for LonMark International since its inception, says the organization. Version 3.4 includes additional compliance requirements for device-response timing so that each certified device's performance will be consistent for a greater range of network management tools.

"The release of Version 3.4 of the Interoperability Guidelines brings us one step closer to the world of plug-and-play connectivity," said Barry Haaser, executive director of LonMark International. "As the world's leading open system standard for open device networking and M2M, the new LonMark guidelines will give manufacturers the essential tools they need to deliver a new generation of easy-to-use products for homes, buildings, factories, transportation systems, and other environments."
