This European Standard was approved by CENELEC on 2011-01-03. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus,
the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,

Foreword
The text of document 65E/162/FDIS, future edition 2 of IEC 61804-3, prepared by SC 65E, Devices and
integration in enterprise systems, of IEC TC 65, Industrial-process measurement, control and automation,
was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61804-3 on
2011-01-03.
This European Standard supersedes EN 61804-3:2007.
1)
The main changes with respect to EN 61804-3:2007 are listed below .
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;
– Clearification on file behaviour, see 7.36.10;
– Add in Table A.5 the new key-words;
– Add the formal EDDL syntax in A.6.
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 nonperfect 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 “”.

1)
The historical background to the EDDL specification is given in Annex E.

- 3 - EN 61804-3:2011
– 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.
– Clearification 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.
– Clearification on SCALING_FACTOR behaviour, see Table 165.
– Deleted EDDL operators from EDDL keyword list, see Table A.5.
– Clarification on TIME_VALUE coding providing the absolute basis, see Table D.16 and Table D.17.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2011-10-03
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-01-03
Annex ZA has been added by CENELEC.
