This European Standard was approved by CENELEC on 2011-08-19. 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 CEN-CENELEC Management Centre 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 CEN-CENELEC Management Centre 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,
Spain, Sweden, Switzerland and the United Kingdom.

Foreword
The text of document 57/1121/FDIS, future edition 2 of IEC 61850-7-1, prepared by IEC TC 57, Power
systems management and associated information exchange, was submitted to the IEC-CENELEC
parallel vote and approved by CENELEC as EN 61850-7-1:2011.

This document supersedes EN 61850-7-1:2003.

Compared to EN 61850-7-1:2003, EN 61850-7-1:2011 introduces:
• the model for statistical and historical statistical data,
• the concepts of proxies, gateways, LD hierarchy and LN inputs,
• the model for time synchronisation,
• the concepts behind different testing facilities,
• the extended logging function.

• the use of numbers for data extension,
• the use of name spaces,
• the mode and behaviour of a logical node,
• the use of range and deadbanded values,
• the access to control actions and others.

The following dates are fixed:
– latest date by which the document has to be implemented at (dop) 2012-05-19
national level by publication of an identical national
standard or by endorsement
– latest date by which the national standards conflicting with the (dow) 2014-08-19
document have to be withdrawn
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent
rights.
