FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60870-5-103 has been prepared by IEC technical committee 57:
Power system control and associated communications.
The text of this standard is based on the following documents:
FDIS Report on voting
57/327/FDIS 57/333/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
Annexes A and B are for information only.

Part 5-103: Transmission protocols –
Companion standard for the informative interface
of protection equipment
1 Scope and object
This section of IEC 60870-5 applies to protection equipment with coded bit serial data transmission for
exchanging information with control systems. It defines a companion standard that enables
interoperability between protection equipment and devices of a control system in a substation. The
defined companion standard utilizes standards of the IEC 60870-5 series.
This section of IEC 60870-5 presents specifications for the informative interface of protection
equipment. This standard does not necessarily apply to equipment that combines protection and
control functions in the same device sharing a single communication port.
This section of IEC 60870-5 describes two methods of information exchange: the first is based on
PPLICATION ERVICE ATA NITS
explicitly specified A S D U (ASDUs) and application procedures for
transmission of ‘standardized’ messages, and the second uses generic services for transmission of
nearly all possible information. The ‘standardized’ messages do not cover all possible protection
functions, and furthermore a protection device may support only a subset of the messages specified in
this standard. For interoperability purposes, in specific applications, this subset has to be specified in
clause 8.
The use of predefined messages and application procedures is mandatory, if applicable. In other cases
generic services shall be used. The ‘private ranges’ defined in this standard are maintained for
compatibility reasons; however, their use is not recommended for future applications.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute
provisions of this section of IEC 60870-5. At the time of publication, the editions indicated were valid.
All normative documents are subject to revision, and parties to agreements based on this section of
IEC 60870-5 are encouraged to investigate the possibility of applying the most recent editions of the
normative documents indicated below. Members of IEC and ISO maintain registers of currently valid
International Standards.

3 Definitions
For the purpose of this section of IEC 60870-5, the following definitions apply.
3.1
companion standard
a companion standard adds semantics to the definitions of the basic standard or a functional profile.
This may be expressed by defining particular uses for information objects or by defining additional
information objects, service procedures and parameters of the basic standard
NOTE – Companion standards do not alter the standards to which they refer, but make explicit the relationship between those
used together for a specific domain of activity.
3.2
enhanced performance architecture (EPA)
a protocol reference model that provides, compared with the full seven layer architecture according to
the basic reference model of ISO/IEC 7498-1, a three layer architecture for obtaining faster response
times for the critical information but with service limitations
3.3
control direction
direction of transmission from the control system to the protection equipment
3.4
monitor direction
direction of transmission from the protection equipment to the control system
3.5
control system
used for the master of the communication link, i.e. the primary station according to IEC 60870-5-2
