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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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.
International Standard IEC 61915-2 has been prepared by the subcommittee 17B:
Low-voltage switchgear and controlgear, of the IEC technical committee 17: Switchgear and
controlgear.

INTRODUCTION
This International Standard follows the rules and uses the framework of IEC 61915-1,
Low-voltage switchgear and controlgear – Device profiles for networked industrial devices –
Part 1: General rules for the development of device profiles. This International Standard is to
define the common set of functionality (data and behaviour) for motor starters and similar
devices thereby allowing system designers, system integrators and maintenance personnel to
handle profile-based devices without a special tool configuration.
This International Standard gives manufacturers and other organizations the common set of
functionality to represent their network capable devices. Manufacturers or other organizations
may use the root device profiles specified to add their manufacturer-specific extensions.

0="NOT READY"
The controller is not able to control the device because at least one
condition is not fulfilled.
NOTE 1 The manufacturer/application of the device will determine the
conditions that have to be fulfilled.
EXAMPLE The conditions which have to be fulfilled may include:
- communication to host established,
- remote control selected,

NOTE 2 Remote monitoring may be possible even if the device is
"NOT READY". For example the parameter “Motor current” may be
transmitted while the device is being operated under local control.

On BOOL na na na na R O 1="ON"
For an electromechanical switching device, the main circuit contacts are
closed.
For a semiconductor switching device, the switches are in the conducting
state.
0="OFF"
For an electromechanical switching device, the main circuit contacts are
open.
For a semiconductor switching device, the switches are in non-conducting
state.
NOTE 1 “ON” doesn’t imply that the motor is running. In simple devices,
such as certain direct-on-line starters, the assumption may be made that
when the starter is "ON", power is available at the incoming connections and
the motor is running. In more complex devices, monitoring of parameters like
"Current" can indicate that the motor is properly running.
NOTE 2 In semiconductor starters, "ON" implies that current is flowing to
the motor.
NOTE 3 ”On” parameter is used for motor starter.
Off BOOL na na na na R O 1="OFF"
For an electromechanical switching device, the main circuit contacts are
open.
For a semiconductor switching device, the switches are in non-conducting
state.
0="ON"
For an electromechanical switching device, the main circuit contacts are
closed. The motor may run forward or run reverse.
For a semiconductor switching device, the switches are in the conducting
state.
NOTE 1 When changing the motion direction of the motor a short
interruption of “ON” may occur.
NOTE 2 ”Off” parameter is used for motor management starter.

In bi-directional systems, energy is being supplied to the motor so that its
direction of rotation is forward. Running forward and running reverse shall
be considered together:
running forward=0 and running reverse =0 “OFF”
running forward=1 and running reverse =0 “RUNNING FORWARD”
running forward=0 and running reverse =1 “RUNNING REVERSE”
running forward =1 and running reverse =1 Shall be defined by the
