Part 2: End to end quality codes for supervisory control

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 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 62361-2 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:
FDIS Report on voting
57/1374/FDIS 57/1390/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.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

INTRODUCTION
The scope of IEC 62361-2 is to create a common list of SCADA quality codes for reference by
other standards to avoid embedding quality code lists in other standards.

Part 2: End to end quality codes for supervisory control
and data acquisition (SCADA)



1 Scope
This part of IEC 62361 documents the quality codes used by existing IEC standards related to
supervisory control and data acquisition (SCADA) in the field of power systems management.
Meter reading quality coding is not considered to be in the scope of this version of the
document. It determines and documents mapping between these standards. Eventual loss of
quality information that might occur in mapping is documented. A cohesive and common list of
quality codes with semantics is defined. The identified standards to be dealt with in this
document are: IEC 60870-5, IEC 60870-6 TASE.2, IEC 61850, IEC 61970, DAIS DA, OPC DA
and OPC UA.
Data covered by this part of IEC 62361 is measurements provided by the following links,
applications or interfaces:
• RTU, 61850 or OPC DA links to SCADA
• Validation added by state estimation
• TASE.2 (ICCP) or TASE.1 (ELCOM) links between control centers
• Servers, e.g. SCADA, that provide OPC or DAIS DA-data.

Figure 1 provides an overview of the IEC power systems information exchange standards.
Refer to IEC/TR 62357-1 (Power systems management and associated information exchange
– Part 1: Reference architecture) for further information.
When data is transmitted using a telecommunications protocol, the quality of the data must be
preserved, and have a common meaning on both side of the transmission.
To facilitate harmonization and simplify maintenance of the standards, all IEC standards in
the field of power systems management and associated information exchange should refer to
this standard regarding quality codes. Specifications for quality codes should not be
developed in the other standards. Upcoming revisions of this document can then work to
harmonize quality codes across several standards.
5 Quality code flow diagram from substation to control center
IEC power systems information exchange standards for substation communication, control
center communication and communication standards intended for exchange of information
between applications at the control center level do have their own quality codes.
The quality codes flow through this chain of hierarchical systems from the IED to the control
center. The quality codes need to be mapped between these standards. As different
standards do not today support the same quality codes and semantics definitions for quality
codes are not
