Full title and description

Electricity metering data exchange - The DLMS/COSEM suite - Part 8-5: Narrow-band OFDM G3-PLC communication profile for neighbourhood networks. This IEC standard defines how the DLMS/COSEM application layer is mapped onto a narrow‑band OFDM G3‑PLC physical and MAC stack (including addressing, adaptation and management) to support neighbourhood (local) metering networks.

Abstract

IEC 62056-8-5:2017 specifies a DLMS/COSEM communication profile for electricity metering that uses narrow‑band OFDM G3‑PLC (based on ITU‑T G.9901 and G.9903) to carry DLMS/COSEM messages over neighbourhood power‑line networks. The profile covers layer usage, addressing and adaptation services necessary to operate the COSEM application process over G3‑PLC-based networks; data-structure specifics for lower-level protocols are out of scope.

Scope

This part of IEC 62056 defines the DLMS/COSEM communication profile for metering purposes that use narrow‑band OFDM G3‑PLC transceivers. It is restricted to profiling how DLMS/COSEM (the application layer and COSEM data model) is transported over G3‑PLC technology — covering physical/MAC selection, IPv6/UDP adaptation, addressing schemes, configuration and management, and COSEM application process considerations for neighbourhood (PAN) metering networks. It references ITU‑T G.9901 and G.9903 for underlying G3‑PLC transceiver and power‑spectral‑density requirements. Data structures specific to lower-level communication protocols remain outside the profile’s scope.

Key topics and requirements

• Definition of the communication layer stack and how DLMS/COSEM is mapped onto G3‑PLC (OFDM physical and MAC layers).
• Use of IPv6/UDP as the network/transport adaptation for DLMS/COSEM traffic in neighbourhood PLC networks.
• Identification, addressing and addressing schemes suitable for meter neighbourhood networks (address assignment and routing considerations).
• Configuration and management procedures for the communication profile, including security and network management considerations appropriate for DLMS/COSEM over PLC.
• Guidance on COSEM application process usage and any additional COSEM interface classes or OBIS assignments proposed for this profile (annex material with examples and normative additions).

Typical use and users

Intended users are utility communications and metering architects, smart‑meter manufacturers, system integrators, firmware/network stack developers, test laboratories and certification bodies implementing or verifying DLMS/COSEM over G3‑PLC neighbourhood networks. The profile is used to ensure interoperable DLMS/COSEM deployments over narrow‑band G3‑PLC in residential and small‑scale neighbourhood metering applications.

Related standards

Key related documents and standards include other parts of the IEC 62056 (DLMS/COSEM) family, and the ITU‑T recommendations that define G3‑PLC operation (ITU‑T G.9901 and G.9903). National and regional adoptions exist as EN 62056‑8‑5 (CENELEC/European adoption) and related corrigenda/adoptions. Implementers will also refer to IPv6/UDP specifications and DLMS/COSEM core parts when implementing this profile.

FAQ

Q: What is this standard?

A: IEC 62056-8-5:2017 is an international standard that defines a communication profile enabling the DLMS/COSEM suite to operate over narrow‑band OFDM G3‑PLC neighbourhood networks.

Q: What does it cover?

A: It covers the mapping of DLMS/COSEM application-layer services onto G3‑PLC physical/MAC layers, addressing and adaptation (IPv6/UDP), configuration and management for neighbourhood metering networks; it does not redefine the lower-level PLC data structures beyond what is needed for the profile.

Q: Who typically uses it?

A: Utilities, smart‑meter manufacturers, firmware and stack developers, integrators, test houses and conformity assessment bodies working on PLC-based neighbourhood metering deployments.

Q: Is it current or superseded?

A: As published, Edition 1.0 (2017) with Corrigendum 1 (Dec 2017) is the active edition; the IEC webstore lists a stability date into 2026 and no full replacement published as of the current IEC bibliographic records. Some national bodies have recorded related revision projects (planning documents) for further DLMS/COSEM profile parts, but a direct full replacement of 62056‑8‑5 had not been published as of the IEC record. Check the IEC catalogue or national standards body for any revisions after 2017 if you need the absolute latest status.

Q: Is it part of a series?

A: Yes — it is one part of the IEC 62056 family (the DLMS/COSEM suite). Part numbering (for example 8‑5) denotes specific communication profiles; other parts cover different media or profiles and the core DLMS/COSEM application/data model.

Q: What are the key keywords?

A: DLMS, COSEM, G3‑PLC, OFDM, PLC, IPv6, UDP, smart metering, neighbourhood network, OBIS.
