CEA, LonMark Announce Standards They Say Will Solve IoT Interoperability Issues
CEA and LonMark International announced two new standards available for home and building automation. The standards give multiple parties -- users, developers, vendors, integrators and specifiers of open building control systems -- a way to develop and deliver a higher…

level of device-to-device interoperability using any open control networking communication platform, said CEA. The intent of the standards is “to offer to the market a very proven, well adopted approach to solving the Internet of Things (IoT) interoperability issue,” said Ron Bernstein, chief ambassador, LonMark. “These profiles can be decoupled from the core ANSI/CEA-709.1 control network protocol and be implemented on any transport, providing a unique opportunity for other standards development bodies to jumpstart their interoperability efforts,” said Bernstein. CEA-709.5 Implementation Guidelines defines the application layer requirements for interoperable devices and how they share key information, status and data across an open control network, said CEA. The application elements, typically deployed on an ANSI/CEA-709.1 LonWorks protocol network, define how to interact with disparate devices from multiple vendors in the same system, improving installation time and integration by “defining units, range and resolution, configuration, and enumeration requirements along with device self-documentation information within the standard,” they said. The new standard enables other transports the option of adopting a common application layer element description library, they said. CEA-709.6 Application Elements built upon the .5 Implementation Guidelines by providing a catalog of more than 100 common device profiles, with more than 380 specific implementation options. The profiles define the mandatory and optional design requirements for standard data variables, standard configuration properties, enumeration types and standard interface file requirements, they said. The library of device profiles includes definitions for HVAC, lighting, security, access, metering, energy management, fire and smoke control, gateways, commercial and industrial I/O, gas detection, generators, room automation, renewable energy, utility, automated food service, semiconductor fabrication, transportation and home and appliances.
