IEC 63345:2023规定了一种数据模型，用于将计量世界抽象为简单的外部消费者显示器。通过本文件中包含的功能块描述的数据模型，规定了可通过简单的外部消费者显示器访问的计量数据的格式。该数据接口通常是仪表通信功能的一部分，并可由简单的外部消费者显示器通过显示器和仪表通信功能之间的CEN/CLC/ETSI TR 50572的H1接口访问。

IEC 63345:2023 specifies a data model to abstract the metering world towards a simple external consumer display. The data model, as described by means of functional blocks contained in this document, lays down the format of metering data accessible by a simple external consumer display. This data interface would be typically part of the meter communication functions and be accessed by a simple external consumer display via the H1 interface of CEN/CLC/ETSI TR 50572 between the display and the meter communication functions.
