What is DLMS (Device Language Message Specification)?
DLMS for Utility Metering Explained
Device Language Message Specification (DLMS) is a standardized communication protocol that spurred a revolutionary transformation in the utility metering industry in the late 1990s. DLMS — along with its key components COSEM (Companion Specification for Energy Metering) and OBIS Code (Object Identification System) — marked a significant milestone in utility management. Built upon the foundation of the International Electrotechnical Commission (IEC) standard 62056, DLMS emerged as a game-changer, offering unparalleled interoperability and flexibility across diverse metering technologies.
Today, as the management and monitoring of utility consumption continue to evolve rapidly, DLMS remains at the forefront. Understanding DLMS requires diving into its components, such as COSEM, OBIS Code, and the foundational IEC 62056 standard. These components form the backbone of modern utility metering systems, ensuring efficiency, accuracy, and compatibility in the ever-changing landscape of utility infrastructure.
What is DLMS Protocol?
DLMS serves as a standardized communication protocol for utility meters, enabling seamless data exchange between meters, data concentrators, and client applications. It acts as a universal language, transcending the barriers of meter manufacturers, to ensure interoperability and compatibility within utility systems.
Understanding DLMS
This protocol not only facilitates efficient communication but also provides a comprehensive framework for managing utility data effectively. By establishing common rules and procedures, DLMS streamlines integration efforts, simplifies deployment processes, and enhances operational efficiency across utility networks.
DLMS Components
DLMS encompasses various components. These include COSEM, OBIS Code, and IEC 62056 standards, which collectively form the foundation of modern utility metering systems. Understanding DLMS is crucial for stakeholders involved in utility management. Such understanding empowers them to leverage DLMS capabilities for driving innovation, improving service delivery, and enhancing customer experience within the utility sector.
Challenges and Implementation
DLMS/COSEM (or IEC 62056) is the main global standard for smart energy metering, control and management. While DLMS presents numerous advantages, implementing DLMS-based solutions comes with challenges, compatibility issues, and cybersecurity concerns that pose significant hurdles in adopting DLMS in utility infrastructure.
Simplifying Energy Metering with the DLMS Client
N3uron’s DLMS Client Module (IEC 62056) streamlines the process to connect and integrate any DLMS-compliant meter with your applications.
Whether you need to integrate the data from your meters into an energy monitoring system, an invoicing application, a SCADA or BMS, N3uron’s DLMS Client Module offers a comprehensive, user-friendly, and affordable solution for energy meter connection and data acquisition.
Data retrieved using the DLMS Client can be easily shared with third-party applications via any Data Delivery module. N3uron supports multiple options, including MQTT Client, OPC UA Server, Sparkplug Client, REST API Server, and much more. This flexibility enables seamless integration with existing systems and opens up limitless possibilities for data integration.
The data acquired from DLMS meters — together with sub-metering values retrieved from other meters through Modbus Client, IEC 102 Client, or any other modules within the N3uron platform — can then be stored in a database using Historian or SQL Client, shown on Web Vision dashboards or used for calculating cost predictions and performance metrics with Derived Tags or Scripting modules.
