IEC 61987-1:20 24 RLV包含官方IEC国际标准及其红线版本。Redline版本仅提供英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 61987-1:20 24定义了一种通用结构，其中应布置工业过程测量装置的产品特征，以便在产品描述从一方转移到另一方时便于理解。它适用于此类设备制造商提供的目录的生产，并帮助用户制定他们的要求。本文件也将作为所有与过程测量设备相关的未来标准的参考文件。此外，该文件还提供了用于产生列出过程控制设备特性的进一步标准的基本结构，例如用于致动器和基础设施设备。 与上一版相比，此版本包括以下重大技术变更: a)在条款5中增加子条款“数字通信”，以便更全面地描述这种接口的特性； b)如引言中所述，将条款标题与IEC CDD的标题一致。

IEC 61987-1:2024 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

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.
