Communication networks and systems in substations -- Part 9-2: Specific Communication Service Mapping (SCSM) - Sampled values over ISO/IEC 8802-3

Defines the Specific Communication Service Mapping for the transmission of sampled values according to the abstract specification in EN 61850-7-2. The mapping is that of the abstract model on a mixed stack using direct access to an ISO/EN 8802-3 link for the transmission of the samples in combination with EN 61850-8-1.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61850-9-2 has been prepared by IEC technical committee 57:
Power systems management and associated information exchange.
The text of this standard is based on the following documents:

INTRODUCTION
This part of IEC 61850 defines the SCSM for sampled values over ISO/IEC 8802-3. The intent
of this SCSM definition is to supplement IEC 61850-9-1 to include the complete mapping of the
sampled value model.
This part of IEC 61850 applies to electronic current and voltage transformers (ECT and EVT
having a digital output), merging units, and intelligent electronic devices for example protection
units, bay controllers and meters.
Process bus communication structures can be arranged in different ways as described in
Annex B and IEC 61850-1. In addition to the transmission of sampled value data sets, which
are directly connected to ISO/IEC 8802-3, a selection of IEC 61850-8-1 services are necessary
to support the access to the SV control block. References to the relevant IEC 61850-8-1
services are provided in this SCSM. For less complex devices (for example merging units) the
sampled value control block can be pre-configured, in which case there is no need to
implement IEC 61850-8-1 services based on the MMS-Stack.
This document defines the mapping of sampled value class model (IEC 61850-7-2) to
ISO/IEC 8802-3. This SCSM, in combination with IEC 61850-7 and IEC 61850-6, allows
interoperability between devices from different manufacturers.
This standard does not specify individual implementations or products, nor does it constrain the
implementation of entities and interfaces within a computer system. This standard specifies the
externally visible functionality of implementations together with conformance requirements for
such functionalities.
Reading Guide
• This document is an extended mapping specification of IEC 61850-9-1 and IEC 61850-8-1
to cover sampled value transmission over ISO/IEC 8802-3.
• This document can best be understood if the reader is thoroughly familiar with IEC 61850-
7-1, IEC 61850-7-2, IEC 61850-7-3 and IEC 61850-7-4.
• The ACSI services defined in IEC 61850-7-2 are not explained in this part of the standard.

COMMUNICATION NETWORKS AND SYSTEMS IN SUBSTATIONS –
Part 9-2: Specific Communication Service Mapping (SCSM) –
Sampled values over ISO/IEC 8802-3
1 Scope
This part of IEC 61850 defines the Specific Communication Service Mapping (SCSM) for the
transmission of sampled values according to the abstract specification in IEC 61850-7-2. The
mapping is that of the abstract model on a mixed stack using direct access to an
ISO/IEC 8802-3 link for the transmission of the samples in combination with IEC 61850-8-1.
Each SCSM consists of three parts:
– a specification of the communication stack being used,
– the mapping of the abstract specifications of IEC 61850-7 on the real elements of the stack
being used, and
– the implementation specification of functionality, that is not covered by the stack being
used.
