What is the spec of DLMS?
DLMS or Device Language Message Specification is a commonly used protocol that facilitates communication between utility control centers, data concentrators and smart meters. Also known as IEC 62056, it is an international standard that was created by the International Electrotechnical Commission (IEC).DLMS — Device Language Message Specification. DLMS/ COSEM (or IEC 62056) is the main global standard for smart energy metering, control and management. It includes specifications for media-specific communication profiles, an object-oriented data model and an application layer protocol.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.

What is the structure of DLMS : The DLMS UA specifications include an object-oriented data model, an application layer protocol and media-specific communication profiles, that standardize message types for various operations, such as reading and writing data. Additionally, it also includes rules for formatting and transmitting these messages.

How does DLMS work

DLMS is a protocol standard that is used in Electricity- , water- and gas meters globally. Protocol standard is needed to read data from different meter types and manufacturers. Using this standard client can talk with the meter and speak the same "language".

Why use DLMS : DLMS supports applications such as remote meter reading, remote control, and value-added services for metering any kind of energy, such as electricity, water, gas or heat. It is an international standard published as IEC 62056.

DLMS (Device Language Message Specification) is a widely used protocol for communication between smart meters, data concentrators, and utility control centers. It is an international standard developed by the International Electro technical Commission (IEC) and is also known as IEC 62056.

DLMS is a very open protocol and it doesn't define what kind of functionality meter must implement. It only describes how to communicate with the meters. Meters are very different. They measure different things and communication channels are very different.

What is DLMS compliant

DLMS compliant energy meter means the meter which adopt the DLMS / COSEM standard suite (IEC 62056 / EN 13757- 1), for example our EM088188, which is specially designed for Iraq, Syria, Afghanistan, Tajikistan etc.IEC 62052-11 specifies general requirements and tests common to all meter types. It covers mechanical, climatic, electrical, and EMC aspects, to ensure that meters are suitable for the application, robust and safe. It replaces the general requirements and tests of earlier standards with a new, harmonised set.DLMS is a protocol standard that is used in Electricity- , water- and gas meters globally. Protocol standard is needed to read data from different meter types and manufacturers. Using this standard client can talk with the meter and speak the same "language".

The ISO/IEC 21823 series standards address issues that relate to interoperability both between different IoT systems and within a single IoT system. ISO/IEC 21823-1 [2] describes a general framework for interoperability for IoT systems.

What does a DLMS meter do : The objective of DLMS is to provide an interoperable environment for structured modeling and meter data exchange. DLMS supports applications such as remote meter reading, remote control, and value-added services for metering any kind of energy, such as electricity, water, gas or heat.

What are the standards of IoT : IoT protocols and standards typically function in a single layer as a distinct part of a larger network—most commonly in the application and middleware layers of a standard five-layer network architecture, although not exclusively. For example, Bluetooth and Wi-Fi operate on the network layer.

What are the most common IEC standards

Currently, the safety principles of IEC 60364 series, IEC 61140, 60479 series and IEC 61201 are the fundamentals of most electrical standards in the world (see table below).

DLMS stands for Device Language Message Specification. The objective of DLMS is to provide an interoperable environment for structured modeling and meter data exchange.An DLMS Energy Meter is a smart device designed to measure and record energy consumption in residential, commercial, and industrial settings. Unlike traditional analog meters, DLMS Energy Meters utilize state-of-the-art digital technology to monitor and collect energy usage data.

What is the ISO standard for IoT : ISO/IEC 21823-1 [2] describes a general framework for interoperability for IoT systems. It includes a five facet model for interoperability that includes transport, syntactic, semantic, behavioural, and policy viewpoints.
