AMENDMENT 1
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

Amendment 1 to IEC 61850-5:2013 has been prepared by IEC technical committee 57: Power

systems management and associated information exchange.

INTRODUCTION

Delete the existing fourth paragraph of the Introduction. Replace the existing text of the fifth

paragraph of the Introduction with the following new text:

The IEC 61850 series shall be long living but allow following the fast changes in communication

technology by both its technical approach and its document structure. The IEC 61850 series

has been organized so that at least minor changes to one part do not require a significant

rewriting of another part. For example, the derived data models in subsequent parts

(IEC 61850-7-x) and mappings to dedicated stacks (IEC 61850-8-x and IEC 61850-9-x) based

on the communication requirements in IEC 61850-5 will not change the requirements defined

in IEC 61850-5. In addition, the general parts, the requirement specification and the modelling

parts are independent from any implementation. The implementation needed for the use of the

standard is defined in some few dedicated parts referring to main stream communication means

thus supporting the long living of the standard and its potential for later technical changes.

Replace the existing text of the sixth paragraph of the Introduction with the following new text:

This consolidated version of IEC 61850-5:2013 and its Amendment 1 defines the

communication requirements for functions and device models for power utility automation

systems.

Replace the existing text of the seventh paragraph and the Note of the Introduction with the

following new text:

The modelling of communication requires the definition of objects (e.g., data objects, data sets,

report control, log control) and services accessing the objects (e.g., get, set, report, create,

delete). This is defined in IEC 61850-7 with a clear interface to implementation. To use the

benefits of communication technology, in this standard no new protocol stacks are defined but

a standardized mapping on existing stacks is given in IEC 61850-8 and IEC 61850-9. A System

configuration language (IEC 61850-6) for strong formal description of the system usable for

software tools and a standardized conformance testing (IEC 61850-10) complement the

standard.

NOTE 1 To keep the layered approach of the standard not mixing application and implementation requirements,

terms like client, server, data objects, etc. are normally not used in IEC 61850-5 (requirements). In IEC 61850-7

(modelling), -8 and -9 (specific communication service mapping) terms belonging to application requirements like

PICOM are normally not used.

NOTE 2 Specific requirements concerning extensions of part 8 are covered in separate technical reports, e.g.

IEC TR 61850-80-3.

1 Scope
Replace the existing text of Clause 1 by the following new text:

The specifications of this document refer to general, respectively core, communication

requirements of the application functions in all domains of power utility automation systems.

Dedicated communication requirements and most examples of application functions in this

document are from the domain substation automation but may be reused in or extended to other

domains within power utility automation systems. Note that sometimes instead of the term

substation automation domain the term substation domain is used, especially if both the

switchyard devices (primary system) and the automation system (secondary system) are

regarded.

The description of the application functions is not used to standardize these functions, but to

identify communication requirements between Intelligent Electronic Devices (IEDs) hosting

these functions within plants and substations in the power system, between such stations (e.g.

between substation for line protection) and between the plant or substation and higher-level

remote operating places (e.g. network control centres) and maintenance places. In addition

interfaces to remote technical services (e.g. maintenance centres) are considered. The general

scope is the communication requirements for power utility automation systems. The basic goal

is interoperability for all interactions providing a seamless communication system for the overall

power system management. Another prerequisite for interoperability is a commonly defined

method for time synchronization.

Standardizing application functions and their implementation is completely outside the scope of

this document. Therefore, it cannot be assumed a single philosophy of allocating application

functions to devices. To support the resulting request for free allocation of these functions, a

proper breakdown of these functions into parts relevant for communication is defined. The

exchanged data and their required performance are defined.

The same or similar IEDs from substations like protective and control devices are found in other

domains like power plants also. Using this document for such devices in these plants facilitates

the system integration e.g. between the power plant control and the related substation

automation system. For some of such other application domains like wind power plants, hydro

power plants and distributed energy resources specific standard parts according to the

IEC 61850 series have been already defined and published.
2 Normative references
Replace the existing text of Clause 2 by the following new text:

The following documents, in whole or in part, are normatively referenced in this document and

are indispensable for its application. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments)

applies.

3 Terms and definitions

Replace the existing text of the first two paragraphs of Clause 3 by the following new text:

For the purposes of this document, the terms and definitions given in IEC TS 61850-2, as well

as the following apply.

ISO and IEC maintain terminological databases for use in standardization at the following

addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
3.1 General

Replace the existing text of terms and definitions 3.1.1 to 3.1.4 with the following new text:

3.1.1
application function
task which is performed in or by power utility automation systems

Note 1 to entry: Generally, an application function consists of subparts which may be distributed to different IEDs,

which exchange data with each other. More precisely these sub-functions implemented in the IEDs exchange data.

Also, between different functions data are exchanged. The exchanged data exposed to the communication system

shall be standardized based on the semantic content to be understandable by the receiving function. For this purpose,

the standard groups the exchanged data in objects called Logical Nodes which refer to the name of the allocated

functions by their mnemonic name.
3.1.2
local function
application function which is performed by sub-functions in one physical device

Note 1 to entry: If the performance of the functions is not depending on functions in other devices no standardized

link is needed. Sometimes, functions with a weak dependency only from other ones are also called local functions.

The loss of such links should not result in blocking these functions but in worst case to some graceful degradation.

3.1.3
distributed function

application function which is performed by sub-functions in two or more different physical

devices

Note 1 to entry: The exchanged data is contained in Logical Nodes having a common semantic reference to the

distributed function. Since all functions communicate in some way, the definition of a local or a distributed function

is not unique but depends on the definition of the functional steps to be performed until the function is defined as

complete. In case of losing the data of one Logical Node or losing one included communication link the function may

be blocked completely or show a graceful degradation if applicable.
3.1.4
system
set of interacting entities which perform a common functionality
Note 1 to entry: The backbone of the system is the data exchange.
3.1.16
logical node (LN)
Replace the existing text of term 3.1.16 with the following new text:
3.1.16
Logical Node (LN)

– 10 – IEC 61850-5:2013/AMD1:2022
 IEC 2022
3.2 Connections
3.2.1
logical connection
Replace the existing text of definition 3.2.1 by the following new text:
communication link between application functions represented by Logical Nodes
3.2.2
physical connection
Replace the existing text of definition 3.2.2 by the following new text:

communication link between intelligent electronic devices (IEDs) and is providing all logical

connections for the implemented application functions represented by Logical Nodes

3.2.4
hidden connection
Replace the existing text of the note to 3.2.4 by the following new text:

Note 1 to entry: This data exchange is not visible and cannot be used by other IEDs therefore not requesting

interoperability. It should be noted that by distributing combined application functions in one IED to more than one

IED hidden connections may get exposed ones which shall be standardized.
3.5 Power utility automation functions at different levels
3.5.2
station level functions

Replace the existing text (not including the note) of definition 3.5.2 with the following new text:

power system application functions referring to the substation or plant as whole
3.5.3
bay level functions
Replace the existing text of definition 3.5.3 with the following new text:

application functions using mainly the data of one bay and acting mainly on the primary

equipment of one bay
3.5.4
process level functions

Replace the existing text of definition 3.5.4 and Note 1 with the following new text:

application functions interfacing to the process, i.e. basically binary and analogue I/O functions

like data acquisition (including sampling) and issuing of commands related to one primary object

(e.g. circuit breaker)

Note 1 to entry: These functions communicate via the logical interfaces IF4 and IF5 to the bay level. The process

level functions may be implemented in the bay level IEDs together with the bay level functions if no process bus is

applied. If a process bus is applied the process level functions are implemented in process level IEDs.

3.5.5
process related station level functions
Replace the existing text of definition 3.5.5 and
...
