IEC 62386-103-2022 PDF

Full title and description

Digital addressable lighting interface - Part 103: General requirements - Control devices. This is the IEC international standard that defines the general requirements, protocol structure and behaviour for control devices used to send digital control signals to electronic lighting equipment (DALI/DALI‑2 style control devices). It is the second edition (2022) replacing the 2014 edition and its 2018 amendment and includes a number of technical updates to memory, instance/identification and bus configuration behaviour.

Abstract

IEC 62386-103:2022 specifies the functional, electrical and protocol-level general requirements for control devices that implement digital addressable lighting interfaces. The document covers device states and modes (including quiescent mode), memory and variable declaration, command definitions and bus configuration so that control devices can interoperate reliably with control gear and system components defined in the IEC 62386 family. It consolidates and revises requirements from the previous edition and amendment.

Scope

This part of IEC 62386 applies to control devices intended to control electronic lighting equipment by means of digital addressable lighting signals. It defines the general behavioural, electrical and protocol requirements necessary for interoperability with other parts of the IEC 62386 series (system components and control gear). The scope includes definition of operating modes, timing (cadencing), declaration of variables, command set structure and memory behaviour for control devices.

Key topics and requirements

• Protocol structure and transmission framing for control-device to control-gear communications.
• Electrical requirements and bus-power considerations for control-device operation.
• Device operating modes including quiescent mode and timing/cadencing rules.
• Declaration and definition of variables and commands (standard command set and behaviour).
• Non‑volatile memory (NVM) handling, save timing and memory-bank definitions (including changes to memory bank 0 and common memory requirements).
• Device identification, instance types and IDENTIFY DEVICE behaviour for commissioning and system management.
• Bus unit configuration and configuration instance handling to support multi‑device systems.

Many of the items above reflect the technical revisions introduced in the 2022 edition compared to the previous edition and amendment.

Typical use and users

IEC 62386-103:2022 is used by manufacturers of lighting control devices (DALI/DALI‑2 controllers, sensors, control panels and gateway devices), lighting control system integrators, test and certification laboratories, product compliance engineers, building automation specifiers and consultants involved in digital lighting projects where interoperable, addressable control is required.

Related standards

IEC 62386 is a multipart series. Closely related parts include IEC 62386‑101 (General requirements – System components) and IEC 62386‑102 (General requirements – Control gear); other parts in the 62386 series define particular requirements for specific control‑gear types and system functions. National/adopted variants (EN/IEC editions) exist for regional use.

FAQ

Q: What is this standard?

A: IEC 62386-103:2022 is the International Electrotechnical Commission standard that specifies general requirements for digital addressable lighting control devices—defining protocol behaviour, electrical and memory requirements so devices can interoperate within DALI-style lighting systems.

Q: What does it cover?

A: It covers functional and electrical specifications, protocol framing and timing (cadencing), operating modes including quiescent state, declaration of variables and commands, non‑volatile memory behaviour and bus unit/configuration requirements for control devices.

Q: Who typically uses it?

A: Lighting control device manufacturers, system integrators, test houses and compliance engineers, building automation specifiers and consultants working on addressable lighting systems use this standard to design, verify and specify interoperable control devices.

Q: Is it current or superseded?

A: The 2022 edition (2.0) is the current edition; it cancels and replaces the 2014 edition and its 2018 amendment. The IEC bibliographic record lists the 2022 publication as the active base publication.

Q: Is it part of a series?

A: Yes — IEC 62386 is a multipart family for digital addressable lighting interfaces. Part 103 addresses control devices; other related parts include 101 (system components), 102 (control gear general requirements) and many part‑2XX/3XX documents that cover particular control‑gear types and functional extensions.

Q: What are the key keywords?

A: Keywords: DALI, DALI‑2, digital addressable lighting interface, control devices, protocol, interoperability, non‑volatile memory, IDENTIFY DEVICE.
