This European Standard specifies data exchange and communications for meters and remote reading of meters in a generic way.

This European Standard establishes a protocol specification for the Application Layer for meters and establishes several protocols for meter communications which may be applied depending on the application being fulfilled.

NOTE

Electricity meters are not covered by this standard, as the standardization of remote readout of electricity meters is a task for CENELEC.
