标准范围

IEC 61804-2:20 18规定了FB（功能块）？通过使用关于几个要素的协调工作的结果。a)定义IEC组件的设备模型？符合61804-2的器械。b)用于测量、驱动和处理的FBs的概念规范。这包括支持控制的基本特征的一般规则，同时避免阻止不同工业部门的创新和专业化的细节。c)电子设备描述(EDD)技术，该技术能够使用工程生命周期的工具集成真实的产品细节。这第三版取消和取代了2006年出版的第二版，并整合了IEC的部分内容？61804-1于2013年1月撤回。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)在条款8中增加了命令通信映射；b)从IEC中移动并重新措辞兼容性级别定义？新附件B的62804-1以及术语和定义；c)在新的附件C中增加了代理概念。

IEC 61804-2:2018 specifies FB (function blocks)？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.
This third edition cancels and replaces the second edition published in 2006 and integrates parts of IEC？61804-1 which was withdrawn in January 2013. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) added command communication mapping in Clause 8;
b) moved and reword compatibility level definition from IEC？62804-1 to new Annex B and terms and definitions;
c) added proxy concept in new Annex C.
