工业过程测量和控制 过程设备目录中的数据结构和元素 第1部分：测量设备的通用结构

[中文适用范围]： 本部分IEC 61987定义了工业过程测量设备产品特性的通用结构，以便于在各方之间传递产品描述时的理解。它适用于此类设备制造商提供的目录制作，并帮助用户制定其要求。 本文件还将作为所有未来涉及过程测量设备标准的参考文件。 此外，本文件还为制定进一步的标准提供了基本结构，以列出过程控制设备的属性，例如执行器和基础设施设备。 [外文原描述]： IEC 61987-1:2024 defines a generic structure in which product features of industrial process measurement devices shall be arranged, in order to facilitate the understanding of product descriptions when they are transferred from one party to another. It applies to the production of catalogues supplied by the manufacturer of such devices and helps the user to formulate their requirements. This document will also serve as a reference document for all future standards which are concerned with process measuring equipment. In addition, this document also provides a basic structure for the production of further standards listing the properties of process control equipment, for example, for actuators and infrastructure devices. This edition includes the following significant technical changes with respect to the previous edition: a) Addition of a subclause “Digital communication” in Clause 5, in order to allow a more comprehensive description of the properties of such an interface; b) Alignment of clause headings, as described in the introduction, to correspond with those of the IEC CDD.
