1 Scope
This Technical Specification is part of the EN 62056 / 52056 DLMS/COSEM suite and it
specifies the DLMS/COSEM communication profiles for power line carrier neighbourhood
networks using the modulation specified in ITU-T G.9904:2012.
There are three profiles specified:
• a profile using the EN 61334-4-32:1996 LLC layer;
• a profile using TCP-UDP/IPv4;
• a profile using TCP-UDP/IPv6.
