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.

state of a function f defined on a subset of the real numbers with real values
Note 1 to entry: Function f is called monotonically non-decreasing, if for all x and y such that x ≤ y one has f(x) ≤
f(y), so f preserves the order. Likewise, a function is called monotonically non-increasing if, whenever x ≤ y, then
f(x) ≥ f(y), so it reverses the order. For this document monotonic is defined as either monotonically non-decreasing
or monotonically non-increasing.
4 General
4.1 General
The requirements of IEC 62386-103:2014 and IEC 62386-103:2014/AMD1:—, Clause 4 apply,

9 Method of operation
9.1 General
The requirements of IEC 62386-103:2014 and IEC 62386-103:2014/AMD1:—, Clause 9 apply,
with the following restrictions and additions.
9.2 Feature type
The feature type shall be equal to 32.
9.3 Feedback type
The supported type of feedback is given in “feedbackCapability” which can be queried. The
encoding of “feedbackCapability” shall be as shown in Table 1.
Table 1 – ”feedbackCapability” encoding
Bit Description Value
0 Visible feedback supported 1 = "Yes"
b
1 Feedback brightness supported 1 = "Yes"
2 Feedback colour supported 1 = "Yes"
3 Audible feedback supported 1 = "Yes"
c
4 Feedback volume supported 1 = "Yes"
5 Feedback pitch supported 1 = "Yes"
a
6 Reserved 0 = default value
a
7 Reserved 0 = default value
a
Reserved for future needs.
b
If visual feedback is supported the variables “feedbackActiveBrightness” and
“feedbackInactiveBrightness” shall be implemented anyhow. The bit Feedback
brightness supported from this table only indicates if the feedback has the
capability to display other values than on or off.
c
If audible feedback is supported the variable “feedbackActiveVolume” shall be
implemented anyhow. The bit Feedback volume supported from this table only
indicates if the feedback has the capability to generate other volumes than on or
off.
Visible and audible feedback share the variables “feedbackActive” and “feedbackTiming”.
NOTE Typically a visible feedback is part of a certain instance, while audible feedback is part of the device as
audible feedback cannot be spatialized by the user to a certain instance but only to the entire device. In such case
the audible and visible feedback can be configured independently through the separate instance and device
variables.
9.4 Feedback control
As long as “feedbackActive” is set to TRUE the feedback shall operate according to the
configuration for active feedback. “feedbackActive” can be set to TRUE by means of the
command ACTIVATE FEEDBACK.
When “feedbackActive” is set to FALSE the feedback shall operate according to the
configuration for inactive feedback. “feedbackActive” can be set to FALSE by means of the
command STOP FEEDBACK.
SELECT FEEDBACK (instanceGroup) shall be used to implement option button functionality.
For all feedback features addressed by this command “feedbackActive” is set to FALSE except
for the feedback features matching the instance group given in the command opcode.
9.5 Feedback configuration
9.5.1 Feedback timing
The variable “feedbackTiming” shall be encoded as shown in Table 2.
Table 2 – “feedbackTiming” encoding
Bit Name Description

2 = 36 % to 39 % (3/8)
3 = 48 % to 53 % (4/8)
4 = 59 % to 66 % (5/8)
5 = 71 % to 79 % (6/8)
6 = 83 % to 92 % (7/8)
7 = 100 % (8/8)
3 period 0 to 7 = period in steps of 0,5 s
in the range of 0,5 s to 4,0 s
0 = 0,4 s to 0,6 s
1 = 0,9 s to 1,1 s
2 = 1,4 s to 1,6 s
3 = 1,9 s to 2,1 s
4 = 2,3 s to 2,7 s
5 = 2,8 s to 3,2 s
6 = 3,3 s to 3,7 s
7 = 3,8 s to 4,2 s
b a
6 cycles 0 = one cycle (one period)
a
1 = two cycles (two periods)
a
2 = three cycles (three periods)
3 = endless
a
After execution of the selected number of cycles “feedbackActive” shall be set to
FALSE automatically.
b
If the duty cycle equals 7 (full period) and cycles equals 3 (endless) the feedback
is controlled by brightness and colour respectively volume and pitch only.
c
A period always starts with its active time.

Optical feedback:
In the active part of a period the visible feedback shall act according to
“feedbackActiveBrightness” and “feedbackActiveColour”. In the remaining part of the period the
feedback shall act according to “feedbackInactiveBrightness” and “feedbackInactiveColour”.

– 12 – IEC 62386-332:2017 © IEC 2017
Audible feedback:
In the active part of a period the audible feedback shall act according to
“feedbackActiveVolume” and “feedbackActivePitch”. In the remaining part of the period the
audible feedback shall be switched off.
Any feedback based on feedback timing shall be restarted when either
ACTIVATE FEEDBACK or SELECT FEEDBACK (instanceGroup) with matching instance
group address is received.
9.5.2 Feedback brightness
The variables “feedbackActiveBrightness” and “feedbackInactiveBrightness” shall be interpreted
as follows:
• A brightness of 0 shall be interpreted as off.
• A brightness of 1 shall be interpreted as minimum brightness.
• A brightness of 255 shall be interpreted as maximum brightness.
• Values from 1 to 255 shall control the brightness in a monotonic way from minimum to
maximum.
• When a feedback supports only on and off, values from 1 to 255 shall be interpreted as
on.
• At graphical or numerical displays values from 0 to 255 shall control the display value in a
monotonic way from minimum to maximum of the display range.
If “feedbackActiveBrightness” or “feedbackInactiveBrightness” is changed either by
SET ACTIVE FEEDBACK BRIGHTNESS (DTR0) or
SET INACTIVE FEEDBACK BRIGHTNESS (DTR0), the new value shall immediately take
effect.
9.5.3 Feedback colour
The variables “feedbackActiveColour” and “feedbackInactiveColour” are only applicable for
visual feedback capable of colour change and shall influence the colour of the feedback as
follows:
The colour shall be encoded as follows:
[bit 1: bit 0]
RED= ⋅ 100 %
Error! Bookmark not defined.Error! Bookmark not defined.
MAX(R,G,B)
[bit 3 : bit 2]
GREEN= ⋅ 100 %
MAX(R,G,B)
[bit 5 : bit 4]
BLUE= ⋅ 100 %
MAX(R,G,B)
Bits 6 and 7 shall be ignored.
MAX (R,G,B) is the maximum value of [bit1:bit0], [bit3:bit2] and [bit5:bit4].
The brightness shall be controlled through “feedbackActiveBrightness” respectively
“feedbackInactiveBrightness”.The value 0 for [bit5:bit0] is not inside the range of validity, see
Clause 10, 11.4.3 and 11.4.5.
NOTE This offers 61 different colour values including white.
If “feedbackActiveColour” or “feedbackInactiveColour” is changed either by
SET ACTIVE FEEDBACK COLOUR (DTR0) or SET INACTIVE FEEDBACK COLOUR (DTR0),
the new value shall immediately take effect.
9.5.4 Feedback volume
The variable “feedbackActiveVolume” shall be interpreted as follows:
• A volume of 0 shall be interpreted as off.
• A volume of 1 shall be interpreted as minimum volume.
• A volume of 255 shall be interpreted as maximum volume.
• Values from 1 to 255 shall control the volume in a monotonic way from minimum to
maximum.
• When a feedback supports only on and off, values from 1 to 255 shall be interpreted as
on.
If “feedbackActiveVolume” is changed by SET ACTIVE FEEDBACK VOLUME (DTR0), the new
value shall immediately take effect.
9.5.5 Feedback pitch
The variable “feedbackActivePitch” is only applicable for audible feedback and shall influence
the pitch of the feedback as follows:
• A value of 0 shall be interpreted as lowest tone.
• A value of 255 shall be interpreted as highest tone.
• All values in between shall control the pitch in a monotonic way from lowest to highest.
If “feedbackActivePitch” is changed by SET ACTIVE FEEDBACK PITCH (DTR0), the new value
shall immediately take effect.
9.5.6 Manual configuration
If IEC 62386-333 is implemented, the feature variables according to Table 1 may be manually
configured. QUERY MANUAL CONFIGURATION CAPABILITY 3xx (see IEC 62386-333) shall
return the byte as defined in Table 3. The particular content of the answer depends on the
type of feature addressing used (instance feature addressing, device feature addressing).

10 Declaration of variables
The requirements of IEC 62386-103:2014 and IEC 62386-103:2014/AMD1:—, Clause 10,
apply with the following additions.
Table 4 shows the default values, the reset values, the range of validity and the type of
memory of the additionally defined variables for feedback.
All variables and commands described in this feature do represent one single feedback
feature. Multiple feedback features can coexist independently in parallel. Each feature is an
extension to either a device or an instance. The particular feature is addressed using feature
addressing within Table 2 of IEC 62386-103:2014 and IEC 62386-103:2014/AMD1:—, 7.2.1.
