CAN/CSA-ISO/IEC 18012-1:05 (R2010)

1 Scope This part of ISO/IEC 18012 specifies requirements for product interoperability in the area of home and building automation systems. It specifies layers six and seven of the OSI reference model (see ISO/IEC 7498-1) with sufficient detail needed to design interoperable home electronic system products, while layers one to five are only specified to the point needed to check whether devices will be able to interoperate with one another. ISO/IEC 18012-1 is applicable to • stand-alone local/home networks, connected devices and applications, • mixed local/home networks, connected devices and applications, • automatically configured devices, • installer configured devices, • installer configured groups/clusters of devices. ISO/IEC 18012-1 specifies interoperability for system set-up, operation and management applied to devices connected to a single home control system or to different home control systems. Although a single uniform home control system would simplify operations, this standard recognises that multiple different networks may co-exist in the same house. This standard specifies requirements to assure that devices from multiple manufacturers work together to provide a specific application. Also, a specific device could be used for multiple applications. ISO/IEC 18012-1 specifies interoperability requirements with respect to • safety, • addressing, • applications, • transport of information, • set-up of devices/elements within home networks – static and/or dynamic binding between objects, • management. This document does not specify how two home control systems share a common resource or how to ensure that two home control systems used within the same premises do not interfere with each other. However, this document requires that two home control systems may share a common resource, and that they do not interfere with one another.
