IEC 61804-3:20 10规定了电子设备描述语言（EDDL）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。它将EDDL指定为描述自动化系统组件属性的通用语言。它以独立于语法的方式指定语义和词汇结构。附录A中定义了特定的语法，但是也可以将语义模型与不同的语法一起使用。这第二版取消并取代了2006年出版的第一版。本版构成技术修订版。与上一版相比的主要变化是: 1.增加: -支持模块化设备的语言元素，参见7.9、7.10、7.36.1、7.36.2、7.36.3、7.36.13和7.36.15； -支持离线配置的语言元素，7。31; -UTF-8的使用，见A.2.3.； -各种内置； -BLOCK_A引用。支持访问多个块的更新，请参见7.4.1、7.38.18至7.38.26。； -向各种词汇结构添加有效性属性； -支持多语言图像，参见7.18.2.1； -在7.23.1中删除了菜单项列表的限制； -7.23.2.1中对条件句的语法限制，以限制菜单布局； -7.23.2.1中菜单项的Add LIST和delete VARIABLE_LIST； -方法类型的附加返回值数据类型，见7.24.2.3； -用表170中的上下文特定规范替换引用； -关键点行为的说明，见7.35.2.4； -在词法结构中加入透明，使属性列表一致，见7.36.11； -关于文件行为的说明，见7。36.10; -在表A.5中加入新的关键词； -在A.6中添加正式的EDDL语法； 2.更正: -在A.6中使用辅助._listR删除所有不需要的构造。这些是由一个不完美的语法检查工具创建的。 -在A.6中删除所有不需要的“stmt1:”和“stmt2:”。这些是由一个不完美的语法检查工具创建的。 -通过以一致的方式修改冒号，使A.6在术语末尾使用冒号的问题上保持一致。 -删除未使用的引用。 -删除了几个词汇结构中的括号和“”。 -删除了词法结构中不可能使用条件表达式的“[]”。 -在指定高度的子句中，将属性WIDTH替换为HEIGHT。 -拼写错误，如GUAGE改为GAUGE。 -对动作中条件句的句法限制（例如参见7。14.2.3和7.14.2.4）仅在方法中支持条件句。 -澄清7.15中的文件行为。 -将网格和图像添加到属性列表中，参见7.19。 -删除了7.23.2.1中重复的元素列表。 -使用参数和返回值定义和调用方法，参见7.24。 -对方法类的限制，见7.24.2.2。 -关于SCALING_F ACTOR行为的说明，见表165。 -从EDDL关键字列表中删除了EDDL运算符，见表A.5。 -关于提供绝对基础的时间值编码的澄清，见表D.16和表D.17。 这个双语版本于2011-07年出版，与英文版相对应。

IEC 61804-3:2010 specifies the Electronic Device Description Language (EDDL) technology, which enables the integration of real product details using the tools of the engineering life cycle. It specifies EDDL as a generic language for describing the properties of automation system components. It specifies the semantic and lexical structure in a syntax-independent manner. A specific syntax is defined in Annex A, but it is possible to use the semantic model also with different syntaxes. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. The main changes with respect to the previous edition are:
1.Additions:
- Language elements to support modular devices, see, 7.9, 7.10, 7.36.1, 7.36.2, 7.36.3, 7.36.13, and 7.36.15;
- Language elements to support offline configuration, 7.31;
- Usage of UTF-8, see A.2.3.;
- Various BuiltIns;
- BLOCK_A referencing. Updates to support access to multiple blocks, see 7.4.1, 7.38.18 up to 7.38.26.;
- Add VALIDITY attribute to various lexical structures;
- Support of multi-language images, see 7.18.2.1;
- In 7.23.1 deleted the restriction of the MENU item list;
- Syntactical limitation on conditionals in 7.23.2.1 to restrict the MENU layout;
- Add LIST and delete VARIABLE_LIST of the MENU items in 7.23.2.1;
- Additional return value data types for METHOD TYPE, see 7.24.2.3;
- Replace reference by a context specific specification in Table 170;
- Clarification on KEY_POINTS behaviour, see 7.35.2.4;
- Add TRANSPARENT to the lexical structure to make the list of attributes consistent, see 7.36.11;
- Clarification on file behaviour, see 7.36.10;
- Add in Table A.5 the new key-words;
- Add the formal EDDL syntax in A.6;
2.Corrections:
- Deleted in A.6 all non-needed constructs using the auxiliary._listR. These were created by a non-perfect syntax-checking tool.
- Deleted in A.6 all non-needed "stmt1:" and "stmt2:". These were created by a non-perfect syntax-checking tool.
- Made A.6 consistent about using a colon at the end of a term by amending colons in a consistent way.
- Deleted not used references.
- Deleted in several lexical structures the brackets and "".
- Deleted in lexical structures the "[ ]" where the conditional expression was not possible.
- Exchanged the attribute WIDTH by HEIGHT in the subclause specifying HEIGHT.
- Spelling errors like GUAGE exchanged to GAUGE.
- Syntactical limitation on conditionals in ACTIONS (for example see 7.14.2.3 and 7.14.2.4) to support conditionals only in the METHODs.
- Clarification on file behaviour in 7.15.
- Add GRID and IMAGES to the attribute list, see 7.19.
- Deleted a duplication of element list in 7.23.2.1.
- Defining and calling METHODs with parameter and return value, see 7.24.
- Restriction on METHOD CLASS, see 7.24.2.2.
- Clarification on SCALING_F ACTOR behaviour, see Table 165.
- Deleted EDDL operators from EDDL keyword list, see Table A.5.
- Clarification on TIME_VALUE coding prov iding the absolute basis, see Table D.16 and Table D.17.
