BS EN IEC 61804-2:2018适用于过程控制功能块（FB）。本文件通过使用协调工作的结果来指定FB 元素。a） 定义符合IEC 61804-2标准的设备组件的设备模型。b） FBs测量、驱动和处理的概念规范。这 包括基本功能的一般规则，以支持控制，同时避免细节 这会阻止不同行业的创新和专业化。c） 电子设备描述（EDD）技术，该技术能够集成真实的 使用工程生命周期工具的产品细节。FB的标准化工作是通过协调对 现有技术。它产生了一个抽象级别，允许定义公共 独特的功能。 这个抽象的愿景在这里被称为“概念FB规范” 并由 工业团体。交叉引用:IEC 61499-1:2012ISO/IEC 7498-1IEC 61158（所有部分）IEC 61131-3IEC 61804-5ISO 9899IEC 61804（所有部分）ISO/IEC 10646ISO/IEC 2022ISO/IEC 19501IEC 60584-1ISO 15745-1IEC 61804-3IEC 60050-351:1998替换BS EN 61804-2:2007（目前仍然有效）购买本文件时可提供的所有当前修订均包含在购买本文件中。

BS EN IEC 61804-2:2018 is applicable to function blocks (FB) for process control.This document specifies FB by using the result of a harmonization work as regards several elements.a) The device model which defines the components of an IEC 61804-2 conformant device.b) Conceptual specifications of FBs for measurement, actuation and processing. This includes general rules for the essential features to support control, whilst avoiding details which stop innovation as well as specialization for different industrial sectors.c) The electronic device description (EDD) technology, which enables the integration of real product details using the tools of the engineering life cycle.The standardization work for FB was carried out by harmonizing the description of concepts of existing technologies. It results in an abstract level that allowed the definition of the common features in a unique way. This abstract vision is called here the "conceptual FB specification" and is mapped to specific communication systems and their accompanying definitions by the industrial groups.Cross References:IEC 61499-1:2012ISO/IEC 7498-1IEC 61158 (all parts)IEC 61131-3IEC 61804-5ISO 9899IEC 61804 (all parts)ISO/IEC 10646ISO/IEC 2022ISO/IEC 19501IEC 60584-1ISO 15745-1IEC 61804-3IEC 60050-351:1998Replaces BS EN 61804-2:2007 which remains currentAll current amendments available at time of purchase are included with the purchase of this document.
