DIN EN 13321-1:2012-12

This European Standard specifies for Home or Building Electronic Systems (HBES) as well as for the domain of Building Automation and Control System Application (BACS) and Building Management common rules for a class of multi-application bus systems where the functions are decentralised and linked through a common communication process. This European Standard specifies the basic requirements for products and systems. The requirements may also apply to the decentralized functions of any equipment connected in a home or building control system if no specific standard exists for this equipment or system. Due to its reference to the EN 50090 series, this European Standard sets requirements for the BACS area in relation to Architecture and Hardware and Application and Communication of systems based on HBES, in which, amongst other areas, the basic requirements for interoperability (between products and systems) are specified. This document (EN 13321-1:2012) has been prepared by Technical Committee CEN/TC 247 "Building Automation, Controls and Building Management", the secretariat of which is held by SNV (Switzerland). Working Committee NA 041-03-68 AA "Gebäudeautomation und -kommunikation (SpA CEN/TC 247/WG 4)" ("Building automation and communication (Mirror committee CEN/TC 247/WG 4)") of the Heating and Ventilation Standards Committee (NHRS) is responsible for the German collaboration at DIN.
