SIST EN 61804-3:2007

Function blocks (FB) for process control -- Part 3: Electronic Device Description Language (EDDL)

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 - enhanced user interface - 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.
