DLMS/COSEM

The Device Language Message Specification (DLMS) is described by the international standard IEC 62056. It defines structured modeling and meter data exchange for an interoperable environment.

DLMS supports applications such as remote meter reading, remote control, and value-added services for metering different kinds of energy, such as electricity, water, gas or heat.

COSEM stands for Companion Specification for Energy Metering. It is an interface model for communicating with energy metering equipment, providing a view of the functionality available through the communications interfaces. The model uses an object-oriented approach.

The COSEM model allows for a manufacturer-independent and controlled method to identify, retrieve and interpret the information held in any meter.

See the DLMS/COSEM and ION technology technote for more information about how DLMS is implemented on your meter.
