FOREWORD
The IEC (International Electrotechnical Commission) is a world-wide organization for standardization
1)
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation 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, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
They have the form of recommendations for international use published in the form of standards, technical
3)
reports or guides and they are accepted by the National Committees in that sense.
In order to promote international unification, IEC National Committees undertake to apply IEC International
4)
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.
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 report of one of the following types:
type 1, when the required support cannot be obtained for the publication of an
•
International Standard, despite repeated efforts;
type 2, when the subject is still under technical development or where for any other
•
reason there is the future but not immediate possibility of an agreement on an
International Standard;
type 3, when a technical committee has collected data of a different kind from that
•
which is normally published as an International Standard, for example "state of the art".
Technical reports of types 1 and 2 are subject to review within three years of publication to
decide whether they can be transfomed into International Standards. Technical reports of
type 3 do not necessarily have to be reviewed until the data they provide are considered to
be no longer valid or useful.

INTRODUCTION
In the area of process control, especially in the area of telecontrol and SCADA systems,
there is an increasing demand for real-time data transmission. Inherent in this type of
application are requirements with respect to data integrity and guaranteed transmission
time.
The applicability of a particular type of communication network with its associated
protocols depends upon its ability to fulfil these requirements. This is a function of a
number of factors, including:
– bandwidth;
– traffic load (normal and avalanche conditions);
– transmission quality;
– coding and encryption schemes;
– computing power of communication front-ends and nodes.
Each candidate system should be evaluated in the light of all of these factors.
In particular, approaches to telecontrol data communication based on the OSI (open-
system interconnection) family of protocols (which were conceived originally for application
to inter-computer communication and not for telecontrol) should be examined very carefully
from this point of view.
IEC 1085 deals with the totality of telecommunications as applied to the administration and
operation of electric power systems. It does not go into detail on the specific needs of
telecontrol.
IEC 870-1-1 describes the general principles of the layout and the functions of telecontrol
systems. Clause 6 of that publication gives already some overviews on the transmission of
telecontrol data, but both the complexity of the data transmission systems, as well as their
numerous applications need a closer look. Due to this fact, a large number of different
publications dealing with standardization of telecontrol protocols will be published.
Therefore, it is necessary to give an overview in this report relating to the basic aspects of
telecontrol data transmission.

TELECONTROL EQUIPMENT AND SYSTEMS –
Part 1: General considerations –
Section 4: Basic aspects of telecontrol data transmission
and organization of standards IEC 870-5 and IEC 870-6
1 Scope and object
This technical report applies to telecontrol equipment and systems with coded bit serial
data transmission for monitoring and control of geographically widespread processes.
This report is intended as a brief tutorial on transmission techniques, equipment and
protocols in view of their use in telecontrol systems. It is thus intended as a guide to orient
those using the standards defined in the series of IEC 870-5 and IEC 870-6. More
precisely, it gives a frame of reference for evaluating solutions as well as defining and
describing the key technical terms. Terms that are defined in IEC 50(371) and in
IEC 870-1-3 are complemented by further definitions in clause 3 of this repo rt .
It further provides:
– descriptions of applicable basic communication technologies;
– basic rules as to how different system layers (see clause 3) can be used together
(i.e. which combinations of standards in different layers are technically coherent and
which are not).
It is not intended to recommend or impose solutions, this being the role of IEC 870-5 and
IEC 870-6.
