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 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 60870-6-802 has been prepared by IEC technical committee 57:
Power system control and associated communications.
This second edition cancels and replaces the first edition published in 1997 and constitutes a
technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
57/575/FDIS 57/583/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.
Annex A is for information only.
The committee has decided that the contents of this publication will remain unchanged
until 2004. At this date, the publication will be:
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

INTRODUCTION
The primary purpose of Telecontrol Application Service Element (TASE.2) is to transfer data
between control systems and to initiate control actions. Data is represented by object
instances. This part of IEC 60870 proposes object models from which to define object
instances. The object models represent objects for transfer. The local system may not maintain
a copy of every attribute of an object instance.
The object models presented herein are specific to "control centre" or "utility" operations and
applications; objects required to implement the TASE.2 protocol and services are found in
IEC 60870-6-503. Since needs will vary, the object models presented here provide only a base;
extensions or additional models may be necessary for two systems to exchange data not
defined within this standard.
It is by definition that the attribute values (i.e. data) are managed by the owner (i.e. source) of
an object instance. The method of acquiring the values are implementation dependent;
therefore accuracy is a local matter.
The notation of the object modelling used for the objects specified in clause 5 is defined in
IEC 60870-6-503. It should be noted that this part of IEC 60870 is based on the TASE.2
services and protocol. To understand the modelling and semantics of this standard, some basic
knowledge of IEC 60870-6-503 is recommended.
Clause 5 describes the control centre-specific object models and their application. They are
intended to provide information to explain the function of the data.
Clause 6 defines a set of MMS type descriptions for use in exchanging the values of instances
of the defined object models. It is important to note that not all attributes of the object models
are mapped to types. Some attributes are described simply to define the processing required
by the owner of the data and are never exchanged between control centres. Other attributes
are used to determine the specific types of MMS variables used for the mapping, and therefore
do not appear as exchanged values themselves. A single object model may also be mapped
onto several distinct MMS variables, based on the type of access and the TASE.2 services
required.
Clause 7 describes the mapping of instances of each object type MMS variables and named
variable lists for implementing the exchange.
Clause 8 describes device-specific codes and semantics to be used with the general objects.
An informative annex is included which describes some typical interchange scheduling
scenarios, along with the use of TASE.2 objects to implement the schedule exchange.

5 Object models
Object models are required for various functions within a system. This clause delineates
abstract object models based on functionality. Object models within one functional area may be
used in another functional area.
5.1 Supervisory Control and Data Acquisition
The object models in this clause are derived from the historical perspective of Supervisory
Control and Data Acquisition (SCADA) systems. The following text presents the context within
which the object models are defined.
Fundamental to SCADA systems are two key functions: control and indication. The control
function is associated with the output of data whereas the indication function is associated with
the input of data. A more recent concept that is finding usage is the control and indication
function where data output may also be input (i.e. bi-directional).
The previous identified functions within SCADA systems are mapped to point equipment
(point). The primary attribute of a point is the data value. SCADA systems define three types of
data for points: analog, digital and state.
The association of one or more points together is used to represent devices. For example, a
breaker device may be represented by a control point and an indication point. The control point
represents the new state that one desires for the breaker device. The indication point
represents the current state of the breaker device. For SCADA to SCADA data exchange (e.g.
control centre to control centre, control centre to SCADA master, etc.), additional data is often
associated with point data. Quality of point data is often exchanged to defined whether the data
is valid or not. In addition, for data that may be updated from alternate sources, quality often
identifies the alternate source. Select-Before-Operate control is associated with Control Points
for momentary inhibiting access except from one source. Two other informative data values
are: time stamp and change of value counter. The time stamp, when available, details when a
data value last changed. The change of value counter, when available, details the number of
changes to the value.
From the context presented, the primary object models required are: Indication Point, and
Control Point. The attributes Point Value, Quality, Select-Before-Operate, Time Stamp, and
Change of Value Counter are required to meet the desired functionality for data exchange. The
Indication Point and Control Point models may be logically combined to a single model to
represent a device which implements a control function with a status indication as to its
success/failure. The combined logical model will result in the same logical attributes, and map
onto the same MMS types as the independent models.

PointName
The PointName attribute uniquely identifies the object.
PointType
The PointType attribute identifies the type of input point, and must be one of the following:
REAL, STATE, DISCRETE.
PointRealValue
The current value of the IndicationPoint, if the PointType attribute is REAL.
PointStateValue
The current value of the IndicationPoint, if the PointType attribute is STATE.
PointDiscreteValue
The current value of the IndicationPoint, if the PointType attribute is DISCRETE.
QualityClass
The QualityClass has the value QUALITY if the object instance has any of the quality attributes
(Validity, CurrentSource, or NormalValue), and takes the value NOQUALITY if none of the
attributes are present.
Validity
The Validity attribute specifies the validity or quality of the PointValue data it is associated with.
These are based on the source system's interpretation as follows:
Validity Description
VALID Data value is valid
HELD Previous data value has been held over. Interpretation is local
SUSPECT Data value is questionable. Interpretation is local
NOTVALID Data value is not valid
