4.0.12 build 627. June 27, 2024.
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.
