该标准将现场总线网络的网关、用于存档和开发数据共享平台的数据存储以及应用单元确定为开发数字社区的重要系统组件，即建设规模和城市范围内无处不在的设施网络基础设施。该标准定义了一个数据交换协议，该协议在基于IPv4/v6的网络上概括和互连这些组件（网关、存储、应用单元）。这使得多个设施、数据存储、应用服务（如中央管理、节能、环境监测和报警通知系统）能够集成。

The standard identifies gateways for field-bus networks, data storage for archiving and developing data sharing platforms, and application units as important system components for developing digital communities, i.e., building-scale and city-wide ubiquitous facility networking infrastructure. The standard defines a data exchange protocol that generalizes and interconnects these components (gateways, storage, application units) over the IPv4/v6-based networks. This enables integration of multiple facilities, data storage, application services such as central management, energy saving, environmental monitoring, and alarm notification systems.
