标准摘要
[中文适用范围]: IEC 61804 的这一部分指定了电子设备描述语言 (EDDL) 技术,该技术可以使用工程生命周期的工具集成真实的产品细节。 IEC 61804 的这一部分将 EDDL 指定为描述自动化系统组件属性的通用语言。 EDDL能够描述设备参数及其依赖关系;设备功能,例如模拟模式、校准;图形表示,例如菜单;与控制设备的交互;图形表示;增强的用户界面;绘图系统;持久数据存储。 EDDL 用于创建电子设备描述 (EDD),例如具体设备、常见可用配置文件或库。该 EDD 与适当的工具一起使用,生成解释性代码,以支持自动化系统组件(例如远程 I/O、控制器、传感器和可编程控制器)的参数处理、操作和监控。工具实现超出了本标准的范围。 IEC 61804 的这一部分以与语法无关的方式指定语义和词汇结构。附件A中定义了特定的语法,但是也可以使用具有不同语法的语义模型。 [外文原描述]: IEC 61804-3:2015 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. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: Builtins and their profiles removed and relocated into IEC 61804-5. The following extensions are integrated in the EDDL specification to meet FDI requirements: - new contructs BLOB, PLUGIN; - component construct for communication server requirements (additional attributes); - extension of the class attribute; - new attributes PRIVATE, VISIBILITY, WRITE_MODE.
