IEC TS 62056-6-9:2016 PDF

Overview

IEC TS 62056-6-9:2016 defines how Common Information Model (CIM) message profiles (IEC 61968-9) are mapped to the DLMS/COSEM data models and protocols (IEC 62056) for electricity metering data exchange. The Technical Specification explains the translation between CIM-based ERP or third‑party systems and DLMS/COSEM‑based metering systems, typically implemented in a Head End System (HES) or a trusted intermediary when end-to-end security exists.

Keywords: IEC TS 62056-6-9, DLMS/COSEM, CIM, IEC 61968-9, mapping, smart metering, HES, AMI, OBIS, meter data exchange

Key Topics

• Reference architecture and use cases: Presents a general reference architecture and 11 concrete use cases (e.g., ReadMeterOnSchedule, ReadMeterOnDemand, ConfigureTariffRemotely, DisconnectReconnectRemotely, SynchronizeClock, ChangeFirmware, RegisterMeter, SuperviseMeter).
• CIM ↔ DLMS/COSEM translation: Specifies how CIM message constructs (verbs, nouns) map to DLMS/COSEM services and parameters.
• Data type and attribute mapping: Covers data type translation and mapping of CIM attributes to DLMS/COSEM attributes (including pricing structure / tariff configurations).
• OBIS and enumerated code mapping: Maps OBIS code groups and values to CIM ReadingType, EndDeviceControlType and EndDeviceEventType enumerations.
• Examples and annexes: Includes illustrative models such as a 2‑rate time-of-use (TOU) tariff and load management by demand limits.
• Operational assumptions: Assumes mapping is usually performed in the HES; if end‑to‑end security is used, mapping may be done in the third‑party CIM system.

Applications

• Utilities integrating enterprise systems (ERP/CRM/OMS) with Advanced Metering Infrastructure (AMI).
• HES vendors implementing protocol translation and message mediation between CIM message profiles and DLMS/COSEM meters.
• System integrators developing forensic, billing, tariff management and remote control functions (tariff configuration, relay control, firmware updates, clock sync).
• Smart grid projects requiring standardized exchanges for meter readings, load management and quality-of-supply reporting.

Who Should Use This Standard

• Utility architects and enterprise integration teams
• Metering equipment and HES manufacturers
• Software developers building protocol adapters for AMI and smart meters
• System integrators and consultants in smart metering and energy management

Related Standards

• IEC 61968-9 (CIM message profiles for meter reading and control)
• IEC 62056 series (DLMS/COSEM suite)
• IEC 62056-1-0 (smart metering architecture references)

This Technical Specification helps ensure interoperable, standards-based mapping between enterprise systems and metering devices - enabling reliable billing, remote control, tariff management and operational visibility across AMI deployments.
