Meter communication
Kamstrup’s electricity meters have internal communication protocols for communicating both via the optical head
and the module connector placed in the module area. The meters enable communication via Kamstrup’s own
optimized protocol KMP.
It is possible for a third party to use the module area of the meter, described in section 8.2.2, for specific
developed modules, and in this connection to use one of the internal protocols implemented in the meter.
7.1
Requirements for third party modules
Below, the minimum requirements for developing modules for Kamstrup’s electricity meters are described.
In general, the design of the module must conform to written and unwritten rules of electrical constructions.
Requirements:
-
Optocouplers must be applied in all connections between module and module connector to avoid
external noise influencing the meter.
-
The module must use the powerful current supply of the meter.
-
It is the responsibility of the third party to secure that the module mounted in a Kamstrup electricity
meter conforms to relevant standards for both meter and module. Kamstrup must accept the results of
these tests. Please contact Kamstrup A/S for further information.
-
The module must be CE labelled.
-
Kamstrup must have two modules for testing purposes before the first delivery is made to the
customer.
7.2
KMP
The KMP protocol gives access to all registers in the meter and enables programming and set-up. Please contact
Kamstrup A/S for requesting a copy of the protocol.
