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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s),
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at

specifications. Part 101 contains general requirements for system components, Part 102
extends this information with general requirements for control gear and Part 103 extends it
further with general requirements for control devices.
The 2xx parts extend the general requirements for control gear with lamp specific extensions
(mainly for backward compatibility with Edition 1 of IEC 62386) and with control gear specific
features.
The 3xx parts extend the general requirements for control devices with input device specific
extensions describing the instance types as well as some common features that can be
combined with multiple instance types.
This first edition of IEC 62386-302 is intended to be used in conjunction with
IEC 62386-101:2014, IEC 62386-101:2014/AMD1:— IEC 62386-101:2022, IEC 62386-
103:2014 and IEC 62386-103:2014/AMD1:— IEC 62386-103:2022. The division of IEC 62386
into separately published parts provides for ease of future amendments and revisions.
Additional requirements will be added as and when a need for them is recognized.

Unless specifically stated otherwise.
c
The maximum value depends on the available positions of the switch with respect to the reported resolution.
d
For sliders and analogue inputs, this column represents the "resolution" most significant bits of "inputValue",
with the remaining bits in accordance with IEC 62386-103:2022, 9.8.2.
An bouncing input signal shall be adequately debounced to ensure
• a single change of "inputValue" reflects the new state of the input signal a maximum of
80 ms from the first change of a bouncing or non-bouncing input signal;
• a single "INPUT NOTIFICATION" event message.
9.3.2 Binary inputs
9.3.2.1 General
For binary inputs the manual/documentation shall clearly state the relationship between
“inputValue” and the externally applied signal. At least the following parameters shall be
specified:
• input signal range that shall be considered to represent an open contact;
• input signal range that shall be considered to represent a closed contact.
9.3.2.2 Switch input
For switch inputs the manual/documentation shall clearly state any particular requirements for
the switches that can be connected.
A position change for a switch shall be considered as one action leading to one event at most.
9.3.3 Analogue inputs
9.3.3.1 General
For analogue inputs the manual/documentation shall clearly state the relationship between
“inputValue” the measured value defined in IEC 62386-103:2022, 9.8.2, and the externally
applied signal. At least the following parameters shall be specified:
• input signal that shall be considered to represent the “inputValue” (0) represented by a
measured value of 0;
REDLINE VERSION – 12 – IEC 62386-302:2017+AMD1:2024 CSV
© IEC 2024
• input signal that shall be considered to represent the “inputValue” represented by a
”resolution”
measured value of ([2 - 1]);
• the physical limits of the input signal that the analogue input can withstand.
Unless specifically stated otherwise the relationship between the input signal and “inputValue”
shall be linear.
9.3.3.2 Slider input
For slider inputs the manual/documentation shall clearly state any particular requirements for
the sliders that can be connected.
9.4 Events
9.4.1 Priority use
9.4.1.1 General
The default “eventPriority” shall be priority 3. Since the application controller needs a timeslot
to respond, “eventPriority” should not be set to 2.
9.4.1.2 Periodic events
The periodic "INPUT NOTIFICATION" message to report the position event shall always be
sent with priority 5.
NOTE This makes "eventPriority" inapplicable for this event only.
9.4.2 Bus usage
9.4.2.1 Instance level
Multiple events from an instance shall not be sent in a transaction. There is a configurable
delay T that shall be taken into account. See 9.5.2 for more information.

9.4.2.2 Device level
At the device level, events from different instances may be sent in a transaction.
9.4.3 Encoding
Position events shall be encoded as shown in Table 2.
Table 2 – Position events
Event name Event Description
information
Position report positionEvent A position report, passing the actual position along.
For the event information of a binary/switch input see Annex A for possible encodings.
The event information of an analogue/slider input shall be encoded as follows:
• if “resolution” ≤ 10: “positionEvent” shall be encoded in such a way that the resulting event
information is a 10-bit value, according to IEC 62386-103:2014 and IEC 62386-
103:2014/AMD1:— IEC 62386-103:2022, 9.8.2;
• in all other cases: “positionEvent” shall provide the 10 MSB bits of the “inputValue”.
© IEC 2024
9.4.4 Event configuration
The application controller may not need all the events mentioned in 9.4.3. The instance shall
allow the application controller to set the “eventFilter” (see IEC 62386-103:2014 and
IEC 62386-103:2014/AMD1:—, 9.7.4) to inhibit those events that the application controller
does not need. For this document, “eventFilter” shall be reduced to one byte.
Events shall be enabled or disabled according to the value of "eventFilter". For this document,
"eventFilter" shall be reduced to one byte. No configuration of "eventFilter" shall prevent the
periodic "INPUT NOTIFICATION" message triggered by the report timer (9.5.1).
NOTE Inhibiting events increases the effective bus bandwidth availability.
The “eventFilter” shall have the definition as given in Table 3:
Table 3 – Event filter
Bit Description Value Default
0 Position event enabled? "1" = "Yes" 1
1 Reserved 0 0
2 Reserved 0 0
3 Reserved 0 0
4 Reserved 0 0
5 Reserved 0 0
6 Reserved 0 0

The filter can be set via “SET EVENT FILTER (DTR0)” and be queried using
“QUERY EVENT FILTER 0-7”, see IEC 62386-103:2014 and IEC 62386-103:2014/AMD1:—
IEC 62386-103:2022 for details.
9.4.5 Event generation
An event shall be generated on every change of “inputValue” or when the report timer expires.
In case a new event occurs before the current event is being sent the new event shall replace
the current event. This could be caused for example by bus unavailability or the deadtime
timer.
9.5 Configuring the input device
9.5.1 Using the report timer
even if the “inputValue” has not
If the report timer is set, it shall trigger an event every T
report
changed. The report timer shall be restarted every time an event is sent.
The report timer shall be started
• at power-on: if enabled, immediately after the receiver has started up, with the time to the
first trigger recommended to be shortened to a random time between 0 s and T s;
report
• otherwise immediately after enablement.
This implies that the first "INPUT NOTIFICATION" message due to the report timer is sent at
a maximum time of T after starting. This may be delayed by other "INPUT
report
NOTIFICATION" messages, or by bus availability.

NOTE If multiple devices have the report timer enabled, they might send out conflicting data used by application
controllers to control the same control gear. Depending on the application care needs to be taken when enabling
the report timer. Application controllers can avoid this problem by enabling only the required report timer(s).
9.5.2 Using the deadtime timer
If the deadtime timer is set, the instance shall not send out an event until the deadtime timer
has expired. The deadtime timer shall be restarted every time an event is sent.
9.5.3 Setting the timers
The event deadtime and report timers shall be programmable as is indicated in Table 4.
For each timer, a fixed minimum duration and a fixed increment duration are given. The
application controller can set the desired actual timer duration by setting the number of
increments to some value in the range [0,255]. The resulting time shall be strictly monotonic
according to the following formula:
Time = T * multiplier
incr
Only on (re-)starting a timer the actual time shall be calculated based on the corresponding
variable. This implies that the times only change after any running timer has been cancelled
or expired. The tolerance on the time shall be ±5 %.

The input device shall expose the following operations to set and observe the timer
multipliers:
• “SET REPORT TIMER (DTR0)”, “QUERY REPORT TIMER” to set or query "tReport";
• “SET DEADTIME TIMER (DTR0)", "QUERY DEADTIME TIMER” to set or query
"tDeadtime".
“SET REPORT TIMER (DTR0)” shall set “tReport” depending on the “DTR0” value. If “tReport”
is set to 0, the report timer shall be disabled immediately.
“SET DEADTIME TIMER (DTR0)” shall set “tDeadtime” depending on “DTR0”. If “tDeadtime” is
set to 0, the deadtime timer shall be disabled immediately, but shall not affect T until the
report
report timer is (re-)started.
If T < T , T shall be T (independent of the value of “tReport”).

from the moment the error occurs until the error is gone.
9.6.2 Error value
“instanceError” can be observed via “QUERY INSTANCE STATUS”.
While “instanceError” is set, “QUERY INSTANCE ERROR” shall return “instanceErrorByte”
according to Table 6:

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 62386-302 has been prepared by subcommittee 34C: Auxiliaries
for lamps, of IEC technical committee 34: Lamps and related equipment.

INTRODUCTION
IEC 62386 contains several parts, referred to as series. The 1xx series includes the basic
specifications. Part 101 contains general requirements for system components, Part 102
extends this information with general requirements for control gear and Part 103 extends it
further with general requirements for control devices.
The 2xx parts extend the general requirements for control gear with lamp specific extensions
(mainly for backward compatibility with Edition 1 of IEC 62386) and with control gear specific
features.
The 3xx parts extend the general requirements for control devices with input device specific
extensions describing the instance types as well as some common features that can be
combined with multiple instance types.
This first edition of IEC 62386-302 is intended to be used in conjunction with
IEC 62386-101:2014, IEC 62386-101:2014/AMD1:—, IEC 62386-103:2014 and
IEC 62386-103:2014/AMD1:—. The division of IEC 62386 into separately published parts
provides for ease of future amendments and revisions. Additional requirements will be added
as and when a need for them is recognized.
The setup of the standards is graphically represented in Figure 1 below.

This document, and the other parts that make up the IEC 62386-300 series, in referring to any
of the clauses of IEC 62386-1XX, specifies the extent to which such a clause is; the parts also
include additional requirements, as necessary.
Where the requirements of any of the clauses of IEC 62386-1XX are referred to in this
document by the sentence “The requirements of IEC 62386-1XX, Clause “n” apply”, this
sentence is to be interpreted as meaning that all requirements of the clause in question of
Part 1XX apply, except any which are clearly inapplicable.
The standardization of the control interface for control devices is intended to achieve
compatible co-existence and multi-master operation between electronic control gear and
lighting control devices, below the level of building management systems. This document
describes a method of implementing control devices.
All numbers used in this document are decimal numbers unless otherwise noted. Hexadecimal
numbers are given in the format 0xVV, where VV is the value. Binary numbers are given in
the format XXXXXXXXb or in the format XXXX XXXX, where X is 0 or 1; “x” in binary numbers
means “don't care”.

3.1
instance
analogue or binary signal processing unit of an input device
[SOURCE: IEC 62386-101:2014, 3.29, modified — addition of “analogue or binary”]
3.2
analogue input
means for the environment to interact with the lighting control system and known to be
represented by a specific value relative to the known upper and lower boundary
3.3
binary input
means for the environment to interact with the lighting control system and known to be in
open or closed state
3.4
bouncing
tendency of any two contacts in an electronic device to generate multiple signals as the
contacts close or open
3.5
debouncing
any kind of hardware device or software that ensures that only a single signal will be acted
upon for a single opening or closing of a contact
3.6
slider
means for the end user to interact with a control lighting system and known to be in a specific
position
3.7
strictly monotonic
either entirely increasing or decreasing without repeating values
Note 1 to entry: Function f defined on a subset of the real numbers with real values is called monotonically
increasing, 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 decreasing if, whenever x < y, then f(x) > f(y) so it reverses the order. For this document
strictly monotonic is defined as either monotonically increasing or monotonically decreasing.
3.8
switch
means for the end user to interact with the lighting control system and known to be in open or
closed state

with the following restrictions and additions.
9.2 Instance type
The instance type (“instanceType”) shall be equal to 2.
9.3 Input signal and value
9.3.1 General
“inputValue” shall reflect the input signal as shown in Table 1.
Table 1 – Relation of input signal and "inputValue"
”inputValue” Slider Analogue input Switch or
binary input
0x00 Minimum position Lower boundary value Open contact
”resolution” b
[0x01,2 - Position indication, linear Linear representation of the value Closed
a c
2] between min. and max. between the upper and lower contact
a
position boundary
”resolution”
[2 - 1] Maximum position Upper boundary value
a
Only applicable if “resolution” ≥ 2.
b
Unless specifically stated otherwise.
c
The maximum value depends on the available positions of the switch with respect to the reported resolution.
A bouncing input signal shall be adequately debounced to ensure
• a single change of “inputValue”;
• a single “INPUT NOTIFICATION” event message.
9.3.2 Binary inputs
9.3.2.1 General
For binary inputs the manual/documentation shall clearly state the relationship between
“inputValue” and the externally applied signal. At least the following parameters shall be
specified:
• input signal range that shall be considered to represent an open contact;
• input signal range that shall be considered to represent a closed contact.
9.3.2.2 Switch input
For switch inputs the manual/documentation shall clearly state any particular requirements for
the switches that can be connected.
A position change for a switch shall be considered as one action leading to one event at most.
9.3.3 Analogue inputs
9.3.3.1 General
For analogue inputs the manual/documentation shall clearly state the relationship between
“inputValue” and the externally applied signal. At least the following parameters shall be
specified:
• input signal that shall be considered to represent the “inputValue” (0);
”resolution”
• input signal that shall be considered to represent the “inputValue” ([2 - 1]);
• the physical limits of the input signal that the analogue input can withstand.
Unless specifically stated otherwise the relationship between the input signal and “inputValue”
shall be linear.

9.4 Events
9.4.1 Priority use
The default “eventPriority” shall be priority 3. Since the application controller needs a timeslot
to respond, “eventPriority” should not be set to 2.
9.4.2 Bus usage
9.4.2.1 Instance level
Multiple events from an instance shall not be sent in a transaction. There is a configurable
delay T that shall be taken into account. See 9.5.2 for more information.
deadtime
9.4.2.2 Device level
At the device level, events from different instances may be sent in a transaction.
9.4.3 Encoding
Position events shall be encoded as shown in Table 2.
Table 2 – Position events
Event name Event Description
information
Position report positionEvent A position report, passing the actual position along.
For the event information of a binary/switch input see Annex A for possible encodings.
The event information of an analogue/slider input shall be encoded as follows:
• if “resolution” ≤ 10: “positionEvent” shall be encoded in such a way that the resulting event
information is a 10-bit value, according to IEC 62386-103:2014 and IEC 62386-
103:2014/AMD1:—, 9.8.2;
• in all other cases: “positionEvent” shall provide the 10 MSB bits of the “inputValue”.
9.4.4 Event configuration
The application controller may not need all the events mentioned in 9.4.3. The instance shall
allow the application controller to set the “eventFilter” (see IEC 62386-103:2014 and
IEC 62386-103:2014/AMD1:—, 9.7.4) to inhibit those events that the application controller
does not need. For this document, “eventFilter” shall be reduced to one byte.
NOTE Inhibiting events increases the effective bus bandwidth availability.
The “eventFilter” shall have the definition as given in Table 3:
Table 3 – Event filter
Bit Description Value Default
0 Position event enabled? "1" = "Yes" 1
1 Reserved 0 0
2 Reserved 0 0
3 Reserved 0 0
4 Reserved 0 0
5 Reserved 0 0
6 Reserved 0 0
7 Reserved 0 0
The filter can be set via “SET EVENT FILTER (DTR0)” and be queried using
“QUERY EVENT FILTER 0-7”, see IEC 62386-103:2014 and IEC 62386-103:2014/AMD1:—
for details.
9.4.5 Event generation
An event shall be generated on every change of “inputValue” or when the report timer expires.
In case a new event occurs before the current event is being sent the new event shall replace
the current event. This could be caused for example by bus unavailability or the deadtime
timer.
9.5 Configuring the input device
9.5.1 Using the report timer
If the report timer is set, it shall trigger an event every T even if the “inputValue” has not
report
changed. The report timer shall be restarted every time an event is sent.
If multiple devices have the report timer enabled, they might send out conflicting data used by
application controllers to control the same control gear. Depending on the application care
needs to be taken when enabling the report timer.
9.5.2 Using the deadtime timer
If the deadtime timer is set, the instance shall not send out an event until the deadtime timer
has expired. The deadtime timer shall be restarted every time an event is sent.
9.5.3 Setting the timers
The event report timer shall be programmable as is indicated in Table 4.
For each timer, a fixed minimum duration and a fixed increment duration are given. The
application controller can set the desired actual timer duration by setting the number of
increments to some value in the range [0,255]. The resulting time shall be strictly monotonic
according to the following formula:
Time = T * multiplier
incr
Only on (re-)starting a timer the actual time shall be calculated based on the corresponding
variable. This implies that the times only change after any running timer has been cancelled
or expired. The tolerance on the time shall be ±5 %.

report
The input device shall expose the following operations to set and observe the timer
multipliers:
• “SET REPORT TIMER (DTR0)”, “QUERY REPORT TIMER”;
• “SET DEADTIME TIMER (DTR0)", "QUERY DEADTIME TIMER”.
“SET REPORT TIMER (DTR0)” shall set “tReport” depending on the “DTR0” value. If “tReport”
is set to 0, the report timer shall be disabled.
“SET DEADTIME TIMER (DTR0)” shall set “tDeadtime” depending on “DTR0”. If “tDeadtime” is
set to 0, the deadtime timer shall be disabled.
If T < T , T shall be T (independent of the value of “tReport”).
report deadtime report deadtime
9.5.4 Manual configuration
If IEC 62386-333 is implemented, the instance level variables according to Table 5 may be
manually configured. QUERY MANUAL CONFIGURATION CAPABILITY 3xx (see
IEC 62386-333) shall return the byte as defined in Table 5:
Table 5 – “manualCapabilityInstance3xx” values
Bit Description Value
0 Manual configuration of “tReport” supported “1” = “Yes”
1 Manual configuration of “tDeadtime” supported “1” = “Yes”
2 Reserved “0”
3 Reserved “0”
4 Reserved “0”
5 Reserved “0”
6 Reserved “0”
7 Reserved “0”
9.6 Exception handling
9.6.1 Manufacturer specific errors
If a manufacturer specific error is detected, the instance shall set “instanceError” to TRUE,
from the moment the error occurs until the error is gone.
9.6.2 Error value
“instanceError” can be observed via “QUERY INSTANCE STATUS”.
While “instanceError” is set, “QUERY INSTANCE ERROR” shall return “instanceErrorByte”
according to Table 6:
Table 6 – “instanceErrorByte” values
Bit Description Value
0 Reserved “0”
1 Reserved “0”
2 Reserved “0”
3 Reserved “0”
4 Manufacturer specific error 1? "1" = "Yes"
5 Manufacturer specific error 2? "1" = "Yes"
6 Manufacturer specific error 3? "1" = "Yes"
7 Manufacturer specific error 4? “1” = “Yes”
If used, the meaning of bits [7:4] of “instanceErrorByte” shall be documented in the
manual/documentation. The impact on event generation shall also be documented.
