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 specifications, 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 technical specification may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
specification when
the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
IEC 60870-6-602, which is a technical specification, has been prepared by IEC technical
committee 57: Power system control and associated communications.
The text of this technical specification is based on the following documents:
Enquiry draft Report on voting
57/466/CDV 57/502/RVC
Full information on the voting for the approval of this technical specification 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 3.

The committee has decided that the contents of this publication will remain unchanged until
2004. At this date, the publication will be
• transformed into an International Standard;
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

Part 6-602: Telecontrol protocols compatible with ISO standards
and ITU-T recommendations – TASE transport profiles
1 Scope
This part of IEC 60870, which is a technical specification, describes the transport profiles for
the IEC 60870-6 series over WAN with reference to international standardized profiles (ISPs)
used by distributed SCADA/EMS applications in control centres, power plants and
substations. The transport profiles use virtually any standard or de facto standard (including
TCP/IP) connection-mode and connectionless-mode network services over any type of
transmission media.
These profiles are part of the telecontrol communication architecture (TCA).
2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this technical specification. For dated references, subsequent
amendments to, or revisions of, any of these publications do not apply. However, parties to
agreements based on this technical specification are encouraged to investigate the possibility
of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of IEC
and ISO maintain registers of currently valid International Standards.
