Overview

EN 50523-2:2009 - Household appliances interworking, Part 2: Data structures - is the CENELEC/CLC European standard that defines the message data structures used for communication between household appliance devices that implement the EN 50523 interworking framework. It is a companion to EN 50523-1 (Functional specification) and establishes how commands, states, events, identification and diagnostic payloads are encoded and exchanged to achieve interoperable control, monitoring and service.

Key topics and technical requirements

• Message format conventions
  • Big‑endian byte order for data fields; 2‑byte words store the most significant byte first.
  • Signed integers use 2’s complement; strings are ASCII null‑terminated.
• Functional blocks (MIDs)
  • EXECUTE COMMAND - standard command IDs (e.g., START = 1, STOP = 2, PAUSE = 3) and parameter encodings for start/finish time, set temperature, program types.
  • SIGNAL STATE - device status codes (e.g., OFF = 1, STAND‑BY = 2, RUNNING = 5, FAILURE = 8), remote‑enable flags, remaining time and temperature reporting.
  • SIGNAL EVENT - event and alert encodings, application error codes (e.g., Command Refused = 1, Invalid OID = 2), structured alert lists with category (WARNING, DANGER, FAILURE) and presence/recovery flags.
  • IDENTIFY PRODUCT - fields for company/brand IDs, model, part/software revision, product type IDs and standard version; Basic and Extended identification formats.
  • COLLECT DIAGNOSIS DATA and MANAGE TIME - standardized MIDs for diagnostics and time management (structure tables defined in the standard).
• Identifiers and encodings
  • Company and Brand Id fields (2 bytes), Product Type Id structure (cluster/category/id), OID encodings and reserved ranges for standard, non‑standard and proprietary values.
• Interoperability rules
  • Clear delineation of standard (1–63), non‑standard (64–127) and proprietary (128–255) value ranges for extensibility.

Applications and users

• Who uses it
  • Appliance manufacturers, firmware and embedded systems engineers, smart‑home integrators, IoT platform developers, service/maintenance tool vendors and standards committees.
• Practical uses
  • Enable cross‑brand remote control, unified status/alert reporting, structured diagnostics and reliable timing for scheduled programs.
  • Build interoperable smart‑home hubs, appliance management apps, and remote service/diagnostic systems that follow a common message/data model.
  • Facilitate vendor-neutral integration in building automation, energy management and consumer device ecosystems.

Related standards

• EN 50523-1: Functional specification - defines the interoperability requirements and should be read together with EN 50523-2 for complete implementation guidance.

Keywords: EN 50523-2, Household appliances interworking, data structures, message formats, MIDs, device communication, interoperability, appliance identification, diagnostics, OID.
