Overview
IEC 62056-46:2002/AMD1:2006 is an Amendment 1 to the IEC 62056-46 standard, addressing electricity metering data exchange for meter reading, tariff, and load control specifically at the data link layer using the HDLC (High-level Data Link Control) protocol. Published by the International Electrotechnical Commission (IEC), this amendment supports enhanced interoperability and communication efficiency in the exchange of metering data. The amendments reflect alignment with the third edition of ISO/IEC 13239 and update terminology, procedures, and referenced standards for improved clarity and precision.
Key Topics
- HDLC Protocol Enhancements: Incorporates frame type 3 (per ISO/IEC 13239) for data link layer communications, providing greater flexibility in the handling of electricity metering data.
- Addressing Schemes: Clarifies that secondary stations in the network may use more than one addressing scheme to support diverse topologies and devices.
- Parameter Negotiation: Updates the negotiation procedure for maximum information field length, allowing for improved data exchange efficiency between primary and secondary stations.
- Terminology Corrections: Standardizes nomenclature, such as consistent usage of “User_Information” and clear definitions of parameters like Destination_MSAP and Source_MSAP.
- Reference Updates: Cites latest related documents, ensuring compatibility with IEC 62051-1 (Glossary), IEC 62056-53 (COSEM Application Layer), IEC 62056-61 (OBIS Object Identification), IEC 62056-62 (Interface Classes), and ISO/IEC 13239.
- Editorial Refinements: Rectifies minor inconsistencies and clarifies technical descriptions for implementers.
Applications
IEC 62056-46:2002/AMD1:2006 is widely adopted in the following areas:
- Smart Metering Systems: Facilitates secure, reliable, and efficient two-way data communication for remote meter reading, tariff management, and load control via standardized HDLC protocol procedures.
- Interoperability Solutions: Enhances compatibility between metering equipment from various vendors, supporting multi-vendor deployments in smart grid infrastructures.
- Utility Data Management: Supports automated and manual data collection strategies for metering data, ensuring accurate billing, load profiling, and demand analysis.
- Networked Metering Environments: Provides essential guidance for data exchange in advanced metering infrastructure (AMI) and supervisory control scenarios.
The standard is especially relevant to electricity utilities, smart metering solution providers, device manufacturers, and system integrators working on digital transformation and automation in energy management.
Related Standards
- IEC 62056 Series: Comprehensive suite for data exchange in metering, notably:
- IEC 62056-53: Defines the COSEM application layer for metering.
- IEC 62056-61: Specifies the OBIS coding system for object identification.
- IEC 62056-62: Details interface classes for metering devices.
- IEC 62051-1: Glossary of terms for consistent terminology.
- ISO/IEC 13239: Governs HDLC procedures essential for compliant data exchange.
- IEC 60050-300 and IEC 62051: References for definitions and terminology in electrical energy measurement.
By adhering to this standard and its amendment, organizations promote standardized, efficient, and reliable electricity metering data exchange, supporting global smart grid and utility modernization initiatives.

INTRODUCTION
This Amendment takes into account that in the third edition of ISO/IEC 13239, frame type 3
has been added as Annex H.4, as requested by IEC TC 13 WG 14, and that second editions
of some parts of the IEC 62056 series are under preparation.
It specifies now that a secondary station may use more than one addressing scheme.
It contains some changes concerning the negotiation of the maximum information length field
HDLC parameter for better efficiency.
References have been updated and some editorial errors have also been corrected.
