IEC 62394:2017

Service diagnostic interface for consumer electronics products and networks - Implementation for ECHONET

IEC 62394:2017 specifies requirements for service diagnostic software to be implemented in products that incorporate a digital interface. The Service Diagnostic Interface (SDI) requires an external controller (exclusive or general-purpose/PC) into which service diagnostic software can be loaded. Parts of the controller software should be standardized while other parts should be unique to the manufacturer. The SDI is based upon ECHONET specification version 2.11, ECHONET Lite specification version 1.11, and APPENDIX Detailed Requirements for ECHONET Device objects Release G, because this interface will be used in future products. The use of this connection and existing communication protocols enable implementation in products at a low cost, with maximum flexibility and efficiency.

Overview

IEC 62394:2017 - Service diagnostic interface for consumer electronics products and networks - Implementation for ECHONET - defines requirements for implementing a Service Diagnostic Interface (SDI) in consumer electronics and networked devices. The standard mandates an external controller (dedicated or general-purpose/PC) to run service diagnostic software, specifies which controller software elements should be standardized versus manufacturer‑specific, and bases the interface on ECHONET specifications (ECHONET v2.11, ECHONET Lite v1.11 and the Release G appendix). The SDI enables low‑cost, flexible, efficient diagnostic implementations using existing communication protocols.

Key Topics and Technical Requirements

• SDI architecture: External controller (tester) and device under test (DUT) roles; support for standalone products, household/facilities networks and remote diagnosis.
• Hardware requirements: Minimum expectations for tester hardware, DUT interfaces and network topology support (local and networked environments).
• Software requirements: Standardized tester software components, manufacturer‑specific modules, and DUT software behaviors to expose diagnostic properties.
• Control protocols: Definitions for two control protocol families - full ECHONET frames and ECHONET Lite frames - including headers, addresses, data counters and service codes.
• ECHONET object model: Detailed object and property specifications (EOJ, EPC, EDT), property data types, required class properties and property maps.
• Device class specifications: Detailed diagnostics for common device classes and sensors (temperature, humidity, illuminance, human detection, energy sensors, open/close sensors, air conditioners, etc.), including operation status, measured values and fault reporting.
• Diagnosis data and services: Product identification, diagnostic unit reading, fault codes, cumulative and instantaneous measurements, and processing counters for compound services.

Practical Applications and Who Uses This Standard

• Consumer electronics manufacturers: Implement standardized diagnostic interfaces in products to simplify field service and warranty support.
• Service and repair centers: Use standardized SDI testers (or software) to diagnose faults, read sensor values and update device settings.
• Firmware and diagnostic software developers: Build compliant tester/client tools and DUT diagnostic modules compatible with ECHONET/ECHONET Lite.
• System integrators and building automation: Integrate device diagnostics into facility management and remote monitoring systems.
• Quality assurance and test labs: Automate device acceptance testing using the SDI and ECHONET object definitions.

• ECHONET specification v2.11
• ECHONET Lite specification v1.11
