EN 14154-4:2014 (E) 5 Introduction This European Standard has been defined as part of the work being undertaken by the European Standards Organizations (CEN/CENELEC/ETSI) under the Commission Mandate M/441. This standard utilizes the six functionalities agreed by the Smart Meters Coordination Group (SM-CG) (see Annex B) as the basis for its additional functionalities. It is not required for the Additional Functionality Device (AFD) to incorporate all functions defined in this standard. Communications for water meters are outside the scope of this standard and are covered by the appropriate parts of EN 13757-1, EN 13757-2, EN 13757-3, EN 13757-4, EN 13757-5 and EN 13757-6 which provide a number of protocols and transport layers for meter communications for Gas, Water and Heat meters. The additional functionality for water meters can be provided by a number of methods; these are illustrated below, see Figure 1, and described in detail within this standard. The AFD can be integrated in the meter, attached to the meter or remote from the meter. SIST EN 14154-4:2015
