Digital addressable lighting interface - Part 105: Particular requirements for control gear and control devices - Firmware transfer
IEC 62386-105:2024 applies to control gear and control devices for control by digital signals of electronic lighting equipment. Typically, a bus unit according to the IEC 62386 series contains firmware. There are circumstances where it can be necessary to change the firmware after production or shipping of the product, for example if the bus unit does not operate as intended. In such a case, a firmware update of a bus unit via the interface is beneficial. This firmware update process is primarily designed to be a bug fix process, not a feature extension process. Nevertheless, the firmware update process can be used for feature extensions. But it is important that the risk of negative effects to the complete system be considered in detail. This second edition cancels and replaces the first edition published in 2020. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) several commands have been modified, renamed and added;
b) variables have been modified and added;
c) recommendations for implementation within emergency control gear have been added;
d) requirements for block acceptance have been changed;
e) example process-flow diagrams have been added;
f) requirements for restarting and power-on have been changed.
Interface d'éclairage adressable numérique - Partie 105: Exigences particulières pour appareillages et dispositifs de commande - Transfert du microprogramme
L’IEC 62386-105:2024 s’applique aux appareillages et dispositifs de commande par signaux numériques des équipements d’éclairage électroniques. Un appareillage de bus conforme à la série IEC 62386 contient généralement un microprogramme. Il peut être nécessaire, dans certaines circonstances, de modifier ce microprogramme après la production ou l’expédition du produit, par exemple lorsque l’appareillage de bus ne fonctionne pas comme prévu. Dans ce cas, il est bénéfique de mettre à jour le microprogramme de l’appareillage de bus par l’intermédiaire de l’interface. Ce processus de mise à jour du microprogramme est principalement conçu comme un processus de correction des bogues et non comme un processus d’extension de caractéristiques. Le processus de mise à jour du microprogramme peut néanmoins être utilisé pour l’extension des caractéristiques. Il est important cependant d’étudier en détail le risque d’effets négatifs sur le système entier. Cette deuxième édition annule et remplace la première édition parue en 2020. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
a) plusieurs commandes ont été modifiées, renommées et ajoutées;
b) des variables ont été modifiées et ajoutées;
c) des recommandations de mise en œuvre dans les appareillages de commande de secours ont été ajoutées;
d) les exigences relatives à l’acceptation des blocs ont été modifiées;
e) des exemples de schémas de flux de processus ont été ajoutés;
f) les exigences relatives au redémarrage et à la mise sous tension ont été modifiées.

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
