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
The purpose of this International Standard is to provide a framework within which IEC product
committees can define profiles for devices within their scope.
NOTE This framework follows the principles given in IEC/TR 62390, the “Common automation device – Profile
guideline”, and refers to ISO 15745, “Industrial automation systems and integration – Open systems application
integration framework”.
Profiles define a common set of functionality (data and behaviour) for a class of devices in a
given industrial domain, thus allowing system designers, system integrators and maintenance
staff to handle profile-based devices without special tool configuration. Profiles also provide
consistent structuring and semantics of device functionality.
This part of IEC 61915 (Part 1) defines general rules for the development of device profiles
for networked industrial devices, including recommendations of general interest and
application, for example a documentation template and a profile exchange language. This will
allow uniformity of profile structure throughout the different device types.
IEC product committees may define “root device profiles” for their devices, in which they will
specify the amount of information which their products should make available through any
network, using the general rules defined in this part of IEC 61915. This will facilitate
uniformity of profiles throughout the corresponding family of devices. These root device
profiles will be published in subsequent parts of the IEC 61915 series.
This International Standard also gives manufacturers or other organizations a common
framework to represent their network capable devices.
Manufacturers or other organizations may use the root device profiles specified by the IEC
product committees for various device types as a basis for developing device profiles
corresponding to their products, using the general rules defined in this part of IEC 61915 to
add the required manufacturer-specific extensions. Alternatively, they may develop their own
device profiles using only the general rules. These manufacturer’s device profiles will typically
be published within the product documentation.
This International Standard facilitates the writing of network independent application software.

DEVICE PROFILES FOR NETWORKED INDUSTRIAL DEVICES –

Part 1: General rules for the development of device profiles

1 Scope
The IEC 61915 series is intended to improve interoperability of devices, network tools and
application software.
This part of IEC 61915 defines a framework for common representation of networked
industrial devices and provides a template for documenting such a representation,
independent of the network used. This framework follows the principles given in
IEC/TR 62390, the “Common automation device – Profile guideline”, and refers to ISO 15745,
“Industrial automation systems and integration – Open systems application integration
framework”.
NOTE 1 The device profile format specified in this part of IEC 61915 is compatible with devices connected to both
bit- and byte-oriented networks.
This part of IEC 61915 applies to root device profiles, generic device profiles, and specific
device profiles. The root device profiles will be published in subsequent parts of the
IEC 61915 series.
NOTE 2 This International Standard is specifically intended for products covered by the IEC 60947 series.
NOTE 3 Organisations such as consortia are encouraged to use the rules defined in this part of IEC 61915 to
develop generic device profiles for use within their own organisations.
Users (product manufacturers and other organizations) should use the root device profiles
together with the rules defined in this part of IEC 61915. This part of IEC 61915 allows users
to make extensions to the root device profiles and/or generic device profiles. Where no
suitable root device profile exists, the user may develop generic or specific device profiles
using the rules defined in this part of IEC 61915.
This part of IEC 61915 recommends the use of a profile exchange language for representation
of the device profile information in order to facilitate the profile’s use by network tools and
application software.
NOTE 4 The types of devices may vary from simple devices, such as pilot lights, push-buttons and limit switches,
to more complex devices with many bytes of information, such as motor controllers, semiconductor motor starters,
etc.

4 Device profiles
4.1 General
A device profile consists of the data (parameters, parameter assemblies and parameter
groups) and behaviour (functional elements, state model and services) provided by the
device. This device profile is used to represent the device independently of the network, e.g.
when designing an industrial automation application.
A device profile shall define the format and content of any control and management
information (see Annex E) that is received and/or sent by the device. Annex A defines the
template for the device profile. The entire template is used as a basis for both root device
profiles and manufacturer’s device profiles. Unless otherwise instructed in this part of
IEC 61915, unused fields shall remain empty.
NOTE 1 If some main template sections are completely empty (e.g. the manufacturer’s header for a root device
profile), these sections may be omitted in the profile.
Each profile shall stand alone without reference to other profiles, i.e. profiles shall not contain
other profiles embedded within them (see Annex C for profile creation guidelines). Simpler
device profiles should be subsets of the parameter lists, parameter assemblies, parameter
groups, state models and services of more complex device profiles, rather than redefining this
information.
Values of the parameters defined by the specific device profile will be transmitted on the
network. The application uses the profile information to interpret the parameter values
exchanged with the device.
NOTE 2 A device profile exists either on paper or in an electronic format.
NOTE 3 A device may store parts or all of the profile information; in this case, this information may also be read
through the network from the device. Format of these exchanges is not covered by this standard.
Parameter assemblies and parameter groups shall only include parameters that are defined in
the device profile.
61915-1 © IEC:2007 – 13 –
Parameter names and device state names shall use the terminology utilised in the
corresponding product standards.
NOTE 4 Annex D gives a recommended syntax for the documentation and transfer of device profiles when using
XML.
4.2 Root device profile
A root device profile is created by the relevant IEC product committee for each device type
(see Note 3 of Clause 1 for use by other organizations).
When defining root device profiles, IEC product committees shall apply the following rules,
unless there is a substantial technical justification.
a) The same parameters shall be used for the root device profiles of all the devices within
a product family.
b) The meaning assigned to the value of each parameter shall be the same throughout
the family, e.g. for a start/stop bit (Boolean) parameter, the value 1 should always
mean start.
c) Similarly, for assemblies the bit and byte order shall be consistent with assemblies in
other root device profiles belonging to the same product family, e.g. in a motor starter
control assembly, the start bit should be in the same position for each type of motor
starter.
A root device profile shall specify which parts of the profile (e.g. parameters) are mandatory,
i.e. required for all devices claiming compliance with this specific root device profile, and
which parts are optional, i.e. need not be used by all devices using this specific root device
profile.
The root device profile shall not include information which is network-specific.
Two practical examples of root device profiles are given in Clause B.2. Figure B.1 provides an
example for a photoelectric switch and Figure B.2 provides an example for a motor starter.
EXAMPLE 1 The photoelectric switch root device profile is an example of a presence sensor device that can be
configured over the network to detect the presence of an object either by the presence of light or the absence of
light, and to transmit a value of 1 over the network for the Presence parameter, indicating the object's presence.
The device can also be put in either configuration or automatic mode and normal or test states by sending the
device appropriate parameters values over the network. The mandatory requirement of the Device and Operate
mode parameters gives the device description “Photoelectric switch with mode control”. A manufacturer’s device
profile could use this root profile to create a device with a profile that only includes the parameters Presence,
Device mode and Operate mode. The device manufacturer’s description could be the same as the root profile. O
