DLMS implementation and integration

The Product is tested according to the specification defined in the Yellow Book[3] for the DLMS
certification.
The Product (physical device) comprises of the management logical device (Product) and one
logical device for each connected meter. The logical devices can be addressed using channel
selection or logical device addressing.
The management logical device holds COSEM management objects, i.e. a list of available logical
devices, clock object, channel selection etc. The meter logical devices hold COSEM objects,
which represent the meter data read from the connected meters.
The meter data is automatically decoded in the Product and a meter template is used to map the
M-Bus data to COSEM objects with assigned OBIS-codes. The meter template can be
configured by the end user.
Meter data can be read from the Product using poll operations or data can be sent to a server
using push operations (configured using the Product GUI). The push operations can be enabled
to send load profiles, billing profiles, event log data and event notifications.
