This European Standard specifies data exchange and communications for meters and remote reading of meters in a generic way.<\/p>\n

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.<\/p>\n

\n
\n NOTE\n <\/div>\n

Electricity meters are not covered by this standard, as the standardization of remote readout of electricity meters is a task for CENELEC.<\/p>\n<\/div>\n
