DLMS COSEM plugin for Advanced TCP/IP Data Logger

Latest version: 5.0.2 build 1002. February 6, 2025.

DLMS/COSEM (IEC 62056, EN13757-1) is the global standard for energy and water smart management, advanced control, and innovative metering. The plugin implements some parts of the DLMS/COSEM protocol to read current values.

The protocol specifies an object-oriented data model, an application layer protocol, and media-specific communication profiles.

DLMS/COSEM comprises three key components:

• COSEM - Companion Specification for Energy Metering - the object model capable of describing virtually any application;
• OBIS - Object Identification System, the naming system of the objects; and 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 virtually over any communication media.

This module has the following features:

• It can read data from any DLMS-compatible device.
• It can initiate a connection using the IEC 62021 protocol.
• The plugin can work with serial and network interfaces.
• The module can retrieve an objects list from a device.
• It can poll DLMS data by a custom interval.
• It can poll data from multiple devices at the same time.
• The module can connect to password-protected devices.
