Foreword
The text of document 57/1065/FDIS, future edition 2 of IEC 61850-7-2, prepared by IEC TC 57, Power
systems management and associated information exchange, was submitted to the IEC-CENELEC
parallel vote and was approved by CENELEC as EN 61850-7-2 on 2010-10-01.
This European Standard supersedes EN 61850-7-2:2003.
The major technical changes with regard to EN 61850-7-2:2003 are as follows:
– class diagrams have been updated;
– data types not required have been removed;
– errors and typos haven been corrected;
– substitution model has been moved to EN 61850-7-3;
– service tracking for control blocks have been added;
– the view concept will be according to the new work on role bases access (RBA);
– security issues are solved by the IEC 62351 series; and
– several terms have been harmonized with those in the other parts.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
In this document, the following print types are used:
– bold is used to highlight defined terms;
– Tahoma is used where the difference between a capital i (I) and a small L (l) is important to see.
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) 2011-07-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2013-10-01
Annex ZA has been added by CENELEC.
