对于楼宇自动化与控制系统应用和楼宇管理（BACS）领域的家用或楼宇电子系统（HBES），本文件规定了一类多应用总线系统的通用规则，其中功能分散并通过通用通信过程连接。本文件规定了产品和系统的基本要求。这些要求也可适用于家庭或楼宇控制系统中连接的任何设备的分布式功能，如果该设备或系统没有特定的标准。 由于参考了EN 50090系列，本文件确定了BACS领域与架构、硬件、基于HBES的系统应用和通信以及其他领域相关的要求，并规定了互操作性（产品和系统之间）的基本要求。

This document specifies, as for Home or Building Electronic Systems (HBES) for the domain of Building Automation and Control System Application and Building Management (BACS), common rules for a class of multi-application bus systems where the functions are decentralised and linked through a common communication process. This document specifies the basic requirements for products and systems. The requirements can also apply to the distributed 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 document establishes requirements for the BACS area in relation to Architecture and Hardware and Application and Communication of systems based on HBES amongst other areas, and specifies the basic requirements for interoperability (between products and systems).
