This part of IEC 61804 specifies the Electronic Device Description Language (EDDL) technology@ which enables the integration of real product details using the tools of the engineering life cycle. This standard specifies EDDL as a generic language for describing the properties of automation system components. EDDL is capable of describing ? device parameters and their dependencies; ? device functions@ for example@ simulation mode@ calibration; ? graphical representations@ for example@ menus; ? interactions with control devices ? graphical representations ?C enhanced user interface ?C graphing system ? persistent data store. EDDL is to be used to create Electronic Device Description (EDD). This EDD is used with appropriate tools to generate interpretative code to support parameter handling@ operation@ and monitoring of automation system components such as remote I/Os@ controllers@ sensors@ and programmable controllers. Tool implementation is outside the scope of this standard. This standard 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. NOTE 1 The EDDL may also be used for the description of product properties in other domains. The EDDL and the device-related EDD is applicable to industrial automation. NOTE 2 Industrial automation may include devices such as generic digital and analog input/output modules@ motion controllers@ human machine interfaces@ sensors@ closed-loop controllers@ encoders@ hydraulic valves@ and programmable controllers. This International Standard satisfies the requirements of Clause 9 of IEC 61804-1.
