How does DLMS protocol work?

How does DLMS protocol work?

DLMS/COSEM (IEC 62056-53, IEC 62056-62) is a standard specification using COSEM for interface modeling equipment and DLMS for data exchange of such metering equipment. It comprises the object model, the application layer protocol and the communication profiles to transport the messages.

What is DLMS for smart meter?

The DLMS / COSEM standard suite (IEC 62056 / EN 13757- 1) is the most widely accepted international standard for utility meter data exchange. Today, DLMS / COSEM forms the basis of large multi-utility smart metering projects using GPRS and PLC networks to transport data.

What is the importance of DLMS?

Its flexibility to offer an application layer independent from the media layer enables utilities and end users to have the same application over any one, or a mix of many, communication technologies.

What is DLMS full form?

DLMS or Device Language Message Specification (originally Distribution Line Message Specification), is the suite of standards developed and maintained by the DLMS User Association (DLMS UA) and has been adopted by the IEC TC13 WG14 into the IEC 62056 series of standards.

What is Interface class in DLMS?

Objects that share common characteristics are generalized as an interface class with a class_id. Within a specific class, the common characteristics (attributes and methods) are described once for all objects. Each instance of an interface class is called a COSEM object.

What is Cosem?

COSEM stands for Companion Specification for Energy Management. The COSEM object model describes the semantics of the language. COSEM interface classes and their instantiations (objects) can be readily used for modelling energy management use cases including metering, yet general enough to model any application.

Where is DLMS located?

Geneva, Switzerland
What is the DLMS User Association? The DLMS User Association is a non-profit organisation, located in Geneva, Switzerland.

What are digital materials?

What are digital materials? Digital materials are those that can be accessed by computers. Some of them are “born-digital,” or originated in a digital form (for example, pictures taken with a digital camera, web pages, twitter feeds, etc.), others were converted into digital files.

What is OBIS in DLMS?

The OBIS (Object Identification System) determines the identification of data objects in DLMS/COSEM communication. The OBIS codes are used as Logical names of data objects. The DLMS User Association defines and allocates OBIS codes, and maintains list of valid OBIS codes.

How do I read OBIS code?

The OBIS value code is located at the beginning of each row in the string. – The A group specifies the medium (0=abstract objects, 1=electricity, 6=heat, 7=gas, 8=water …) – The B group specifies the channel.

What does DLMS(device language) mean?

Answer Wiki. generally..DLMS (Device language message specification) protocol is widely used in the energy market(electricity, water and gas) across the world. It is very interesting protocol for those who having the interest in the energy efficiency market products..

What is the difference between DLMS/COSEM?

DLMS – Device Language Message Specification – the application layer protocol that turns the information held by the objects into messages. DLMS/COSEM can be used for all utilities / energy kinds, all market segments, all applications and over virtually any communication media. COSEM COSEM stands for Companion Specification for Energy Metering

What are the line categories supported by the DLMs server?

Supported line categories: Serial, SerialOverUDP Device Redundant, TCP/IP-TCP , TCP/IP-TCP Redundant , MOXA IP Serial Library , RFC2217 Client , MODEM. Communication protocol ” DLMS/COSEM “. The station address (DLMS Server HDLC/MAC Address) consists of two parts: Upper MAC Address and Lower MAC Address.

Who is responsible for the international standards for DLMS?

The DLMS User Association has established a D Type liaison with IEC TC13 WG14, responsible for international standards for meter data exchange and establishing the IEC 62056 series. [3] COSEM (Companion Specification for Energy Metering), includes a set of specifications that defined the “transport and application layers” of the DLMS protocol.
