Automatic Meter Reading, or more general - Demand Side Management - needs universal definitions, needs communication standards. DLMS/COSEM is the common language so that the partners can understand each other.
DLMS:
“Device Language Message specification” - a generalised concept for abstract modelling of communication entities
COSEM:
“COmpanion Specification for Energy Metering” - sets the rules, based on existing standards, for data exchange with energy meters
What is DLMS/COSEM?
- An object model, to view the functionality of the meter, as it is seen at its interface(s)
- An identification system for all metering data
- A messaging method to communicate with the model and to turn the data to a series of bytes
- A transporting method to carry the information between the metering equipment and the data collection system
