IEC 62394:2024 specifies requirements for service diagnostic software to be implemented in products that incorporate a digital interface. It does not specify requirements for carrying out remote diagnosis or for manufacturer-dependent software.
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 are standardized while other parts are proprietary to the manufacturers.
To reach a common approach in servicing all products from all manufacturers, it is necessary to standardize specific items to be tested in products and certain aspects of controllers' diagnostic software.
The SDI is based upon ECHONET specification version 2.11, ECHONET Lite specification version 1.13, and APPENDIX Detailed Requirements for ECHONET Device objects Release Q rev. 1, 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.
The SDI consists of
• specific hardware and software requirements of the device under test (DUT);
• specific requirements of the controller:
– the service software;
– an ECHONET interface;
• the connection between the controller and the DUT.
This document provides the minimal requirements necessary to carry out computerized diagnosis. It covers the standardized software of the controller as well as the standardized software and provisions in the DUT.

• optionally, provide additional functions other than those for measurement of electrical energy.
This document also applies to transducer-operated meters or meters designed for operation with Low Power Instrument Transformers (LPIT) or sensors (as defined in the IEC 61869 series).
When equipment in scope of this document is designed to be installed in a specified matching socket, then the requirements apply to, and the tests are performed on, equipment installed in its specified matching socket. However, requirements for sockets and inserting / removing the meters from the socket are outside the scope of this document.
This document is also applicable to auxiliary input and output circuits, operation indicators, and test outputs of equipment for electrical energy measurement.
Equipment used in conjunction with equipment for electrical energy measurement and control may need to comply with additional safety requirements. See also Clause 13.

• portable meters;
• meters used in rolling stock, vehicles, ships and airplanes;
• laboratory and mobile meter test equipment;
• reference standard meters;
• conventional or low power instrument transformers;
• equipment with solid-state or other non-electromechanical supply and load control switches.
The safety requirements of this document are based on the following assumptions:
• metering equipment has been installed correctly;
• metering equipment is used generally by ordinary persons, including meter readers and consumers of electrical energy. In many cases, it is installed in a way that it is freely accessible. Its terminal covers cannot be removed, and its case cannot be opened without removing seals (if present) and using a tool;
• during normal use all terminal covers, covers and barriers providing protection against accessing hazardous live parts are in place;
• for installation, configuration, maintenance and repair it may be necessary to remove terminal cover(s), (a part of) the case or barriers so that hazardous live parts may become accessible. Such activities are performed by skilled persons, who have been suitably trained to be aware of working procedures necessary to ensure safety. Therefore, safety requirements covering these conditions are out of the Scope of this document.
