IEC 62386-104:2019

Digital addressable lighting interface - Part 104: General requirements - Wireless and alternative wired system components

IEC 62386-104:2019 The IEC 62386 series specifies a bus system for control by digital signals of electronic lighting equipment. This part of IEC 62386 applies to a system with wireless or alternative wired communication between its units, instead of a wired bus system, where the meaning of “wireless or alternative wired communication”, or in short “telecommunication”, is any type of communication network different from the wired system described in IEC 62386-101.
Where the electronic lighting equipment is covered by the scope of IEC 61347 (all parts), it is in line with the requirements of IEC 61347 (all parts), with the addition of DC supplies.

Interface adressable d'éclairage numérique - Partie 104 : Exigences générales - Composants de système à connexion alternative ou sans fil

IEC 62386-104:2019 La série IEC 62386 spécifie un réseau de bus pour la commande par des signaux numériques des appareils d'éclairage électroniques. La présente partie de l'IEC 62386 s'applique à un système équipé d'une communication sans fil ou filaire alternative entre ses unités, plutôt qu'à un réseau de bus filaire, où la signification de "communication sans fil ou filaire alternative", abrégée en "télécommunication", se réfère à tout type de réseau de communication autre que le réseau filaire décrit dans l'IEC 62386-101.
Lorsque les appareils d'éclairage électroniques relèvent du domaine d'application de l'IEC 61347 (toutes les parties), ils sont conformes aux exigences de l'IEC 61347 (toutes les parties) par l'ajout d'alimentations en courant continu.

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.

INTRODUCTION
IEC 62386 contains several parts, referred to as series. The IEC 62386-1xx 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 IEC 62386-2xx series extends 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 IEC 62386-3xx series extends 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 62386-104 is intended to be used in conjunction with IEC 62386-101,
IEC 62386-102 and the various parts that make up the IEC 62386-2xx series for control gear,
and with IEC 62386-103 and the various parts that make up the IEC 62386-3xx series of
particular requirements for control devices. The division 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 recognised.
The setup of the standards is graphically represented in Figure 1.

Part 104: General requirements –
Wireless and alternative wired system components

1 Scope
The IEC 62386 series specifies a bus system for control by digital signals of electronic lighting
equipment. This part of IEC 62386 applies to a system with wireless or alternative wired
communication between its units, instead of a wired bus system, where the meaning of
“wireless or alternative wired communication”, or in short “telecommunication”, is any type of
communication network different from the wired system described in IEC 62386-101.
Where the electronic lighting equipment is covered by the scope of IEC 61347 (all parts), it is
in line with the requirements of IEC 61347 (all parts), with the addition of DC supplies.
NOTE the definition of “telecommunication” applies only to this document and differs from the IEC Electropedia
term in IEC 60050-701:1988, 701-01-05.

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.
This consolidated version of the official IEC Standard and its amendment has been
prepared for user convenience.
IEC 62386-104 edition 1.1 contains the first edition (2019-05) [documents 34/600/FDIS
and 34/611/RVD] and its amendment 1 (2023-12) [documents 34/1048/CDV and
34/1131/RVC].

INTRODUCTION
IEC 62386 contains several parts, referred to as series. The IEC 62386-1xx 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 IEC 62386-2xx series extends 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 IEC 62386-3xx series extends 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 62386-104 is intended to be used in conjunction with IEC 62386-101,
IEC 62386-102 and the various parts that make up the IEC 62386-2xx series for control gear,
and with IEC 62386-103 and the various parts that make up the IEC 62386-3xx series of
particular requirements for control devices. The division 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 recognised.
The setup of the standards is graphically represented in Figure 1.

DIGITAL ADDRESSABLE LIGHTING INTERFACE –

Part 104: General requirements –
Wireless and alternative wired system components

1 Scope
The IEC 62386 series specifies a bus system for control by digital signals of electronic lighting
equipment. This part of IEC 62386 applies to a system with wireless or alternative wired
communication between its units, instead of a wired bus system, where the meaning of
“wireless or alternative wired communication”, or in short “telecommunication”, is any type of
communication network different from the wired system described in IEC 62386-101.
Where the electronic lighting equipment is covered by the scope of IEC 61347 (all parts), it is
in line with the requirements of IEC 61347 (all parts), with the addition of DC supplies.
NOTE the definition of “telecommunication” applies only to this document and differs from the IEC Electropedia
term in IEC 60050-701:1988, 701-01-05.

4.1 Purpose
The standardization of the digital addressable lighting interface is intended to achieve
interoperable multi-vendor operation below the level of building management systems.
EN 50491 and ISO 14672 are not applicable for the purposes of this document.
IEC 62386-101:2014, 4.1 applies.
4.2 Version number
The requirements of IEC 62386-101:2014 and IEC 62386-101:2014/AMD1:2018, 4.2 apply,
except “101” shall be replaced by “104”.
4.3 System structure and architecture
A system shall consist of the components listed in Table 1.

Component Quantity For detailed information see
control gear ≥ 0 IEC 62386-102
application controller ≥ 1 IEC 62386-103

Where in IEC 62386-102, IEC 62386-103, the IEC 62386-2xx or IEC 62386-3xx series,
reference is made to IEC 62386-101:2014 and IEC 62386-101:2014/AMD1:2018, the
reference shall instead be redirected to the respective clauses of this document.
All telecommunication units within the same telecommunication system shall be capable of
transmitting and receiving through their telecommunication interface.
NOTE As a consequence of the above, every frame is visible to all control gear and control devices in the same
telecommunication system.
If there are several co-located systems, such as within the same RF reception range or on the
same PLC line, the frames of one telecommunication system shall be visible only by the
telecommunication interfaces of that specific system.
Figure 2 shows an example of a telecommunication system structure.

See Annex D for information on possible telecommunication system architectures.
NOTE The interface of all the telecommunication system units in Figure 2 uses the same underlying
telecommunication protocol, as defined in 3.4.
4.4 System information flow
Figure 3 shows the different frame types that are used for communication between the
telecommunication units in a telecommunication system. A backward frame is only ever
transmitted in response to a forward frame.

Figure 3 – Example of communication between telecommunication units
Within the telecommunication system, there shall be no direct information flow between input
devices and control gear.
NOTE A system conforming to this document may consist of an application controller and control gear only – see
Clause D.1. In such a system, user input need not result in transmission of forward frames.
4.5 Command types
The requirements of IEC 62386-101:2014, 4.5 apply.
4.6 Telecommunication units
4.6.1 General
The telecommunication unit shall implement one of the underlying telecommunication
protocols as listed in Annex B. All telecommunication units of a telecommunication system
shall use the same underlying telecommunication protocol (see definition 3.4).
4.6.2 Telecommunication transmitters and receivers in telecommunication units
Table 2 summarizes the types of frames that the different types of telecommunication units
may transmit or receive.
