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.

INTRODUCTION
This part of IEC 60870-5 specifies methods and procedures for conformance testing of
Telecontrol equipment or systems using IEC 60870-5 standard(s).
This part of IEC 60870-5 contains general subjects and guidelines for the test environment.
Detailed test cases, mandatory and optional mandatory test cases for the companion
standards will become available as technical specifications (IEC 60870-5-60x).
Tests according to EMC requirements or related to environmental and organisational
conditions are beyond the scope of this part of IEC 60870-5. This part of IEC 60870-5 only
focuses on the protocol implementation and the related system functionality necessary to
validate the protocol implementation.

TELECONTROL EQUIPMENT AND SYSTEMS –
Part 5-6: Guidelines for conformance testing for
the IEC 60870-5 companion standards
1 Scope
This part of the IEC 60870-5 series specifies methods for conformance testing of telecontrol
equipment, amongst Substation Automation Systems (SAS) and telecontrol systems, including
front-end functions of SCADA.
The use of this part of IEC 60870-5 facilitates interoperability by providing a standard method
of testing protocol implementations, but it does not guarantee interoperability of devices. It is
expected that using this part of IEC 60870-5 during testing will minimize the risk of non-
interoperability.
The goal of this part of IEC 60870-5 is to enable unambiguous and standardised evaluation of
IEC 60870-5 companion standard protocol implementations. The guidelines and conditions for
the testing environment are described in this part of IEC 60870-5. The detailed test cases per
companion standard, containing among others mandatory and optional mandatory test cases
per Basic Application Function, ASDU and transmission procedure, will become available as
technical specifications (IEC 60870-5-60x). Other functionalities may need test cases, but this
is beyond the scope of this part of IEC 60870-5.
This part of IEC 60870-5 deals mainly with communication conformance testing; therefore
other requirements, such as safety or EMC are not covered. These requirements are covered
by other standards (if applicable) and the proof of compliance for these topics should be done
according to those standards.

3 Terms and definitions
For the purposes of this part of IEC 60870-5, the following terms and definitions apply.
3.1
configuration (of a system or device)
step in system design: selecting functional units, assigning their locations and defining their
interconnections
3.2
configuration list
supplies an overview of all compatible hardware and software versions of components of
controlled/controlling stations including the software versions of relevant supporting tools
3.3
address config
address config is the configuration file containing the ASDU-addressing including the
information object addresses necessary to test all the functionality defined as in the PID
3.4
conformance test
verification process of the protocol implementation in a device by executing tests according to
the applicable test plan, which contain mandatory and possibly mandatory optional test cases,
so as to be able to answer the following question:
“Does the protocol implementation in device xxx of supplier yyy conform to the
IEC 60870-5-10x standard and the applicable Protocol Implementation Document (PID)?”
NOTE A supplier-independent party that is allowed to issue a Conformance Statement can carry out a
conformance test.
3.5
device
mechanism or piece of equipment designed to serve a purpose or perform a function
[IEEE STD 100-1996, IEEE Dictionary of Electrical and Electronic Terms]
3.6
direction
communication direction in which the device exchanges the data
NOTE IEC 60870-5 companion standards describe functions and ASDU’s in the monitor direction (from the
controlled to the controlling station) and control direction (from controlling to controlled station) as Normal direction
(N). For some purposes, the functions or ASDU’s can be used also in the Reverse direction (R) or in Both
directions (B). The way they are used should be indicated in the PICS. If reversed direction is enabled, by using R
or B, the functionality is used in the reverse direction, the applicable test cases in the normal direction are
applicable for the reversed functionality.
3.7
error
behaviour, which does not conform to the standard and/or the applicable test cases as
described in this part of IEC 60870-5
3.8

– 8 – 60870-5-6 © IEC:2006(E)
3.9
function
tasks performed by the telecontrol equipment
NOTE Generally, functions will exchange data with each other.
3.10
hold point
H
point, defined in the appropriate document beyond which an activity should not proceed
without the approval of the initiator of the conformance test. If necessary, the test facility
could provide a written notice to the initiator at an agreed time prior to the hold point. The
initiator or his representative is obliged to verify the hold point and approve the proceeding of
the activity
3.11
quality program
quality program for the IEC 60870-5 series as described in Figure 3
3.12
initiator of conformance test
party initiating a conformance test that may be executed by a test facility
3.13
interface
shared boundary between two functional units, defined by functional characteristics, signal
characteristics, or other characteristics as appropriate
3.14
interoperability
ability of two or more telecontrol devices from the same vendor, or different vendors, to
exchange information and use that information for correct co-operation
3.15
interoperability test
verification of the information exchange of two or more devices from the same vendor or
different vendors.
In case of an open protocol, the test shall give an answer to the following question:
“Are the devices under test (DUT) able to communicate correctly according to the
IEC 60870-5-10x standard and the Protocol Implementation Document (PID)?”
The interoperability test can be carried by a supplier-independent party that may result in an
interoperability statement. A basic condition for this interoperability test is a passed
conformance test of both devices
NOTE Interoperability does not necessarily mean that both systems are communicating according a specific
protocol, but that both those devices are able to communicate and this might be an open protocol. Interoperability
is not interchangability.
3.16
interchangability
ability to replace a device from the same vendor, or from different vendors, using the same
communication interface and as a minimum, with the same functionality, and with no impact
on the rest of the system

items regarding the requirements in 5.6.3.
NOTE Applicable tolerances may be part of the PIXIT.
3.23
Protocol Implementation eXtra Information for Testing
PIXIT
the PIXIT document contains system specific information regarding the capabilities of the
system to be tested and specifies which items are optional, in the applicable Companion
Standard or outside the scope of the 60870-5 series. The PIXIT is not subject to
standardisation, but 5.5.1.4 describes guidelines and recommendations for setting up a PIXIT
NOTE It is recommended is to integrate the PIXIT and the PICS into one document, which is the PID.
3.24
positive test
test to ensure the correct implementation of the system capabilities as defined by the
supplier. A positive test has a described and defined response
