What is DLMS?


DLMS stands for Distribution Line Message Specification. It is an application layer specification, independent of the lower layers and thus of the communication channel, designed to support messaging to and from (energy) distribution devices in a computer-integrated environment. It is an international standards established by IEC TC 57 and published as IEC 61334-4-41.

The concept was driven forward later to become Device Language Message Specification with the objective to provide an interoperable environment for structured modelling and meter data exchange. Applications like remote meter reading, remote control and value added services for metering any kind of energy, like electricity, water, gas or heat are supported.
