IEC 61804-3:2015

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. This bilingual version, published in 2011-07, corresponds to the English version.

IEC 61804-3:2020 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 document 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 used to create electronic device description (EDD) for e.g. concrete devices, common usable profiles or libraries. This EDD is used with appropriate tools to generate an 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 document. This document 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. IEC 61804-4 specifies EDD interpretation for EDD applications and EDDs to support EDD interoperability. IEC 61804-5 specifies the EDDL builtin library and provides the profiles of the various fieldbuses. This fourth edition cancels and replaces the third edition published in 2015. This edition constitutes a technical revision. This edition was developed by merging material from multiple variants of existing EDDL specifications including those from FieldComm Group (FOUNDATION? Fieldbus , HART® ), PROFIBUS? Nutzerorganisation e.V. (PNO), and ISA100_Wireless? Compliance Institute (ISA100 WCI). Any places where there may be a profile deviation are now indicated in the context where the related deviation is found. As a result, the formatting and numbering of this edition may be different from any of the individual specifications from which this edition was derived. This edition includes the following significant technical changes with respect to the previous edition: ? Communication profiles ISA100 and GPE were added. ? EDD Identification Information has a new LAYOUT_TYPE attribute. ? New construct SEMANTIC_MAP was added. ? CLASS attribute values LOCAL_A and LOCAL_B were added. ? Extended LIST functionality to support device managed lists.
