scope:

This International Standard specifies DLMS/COSEM wired and wireless M-Bus communication profiles for local and neighbourhood networks. NOTE Setting up and managing the M-Bus communication channels of M-Bus devices, the M-Bus network, registering slave devices and - when required - repeaters is out of the Scope of this International Standard. NB: The scope of this communication profile standard is restricted to aspects concerning the use of communication protocols in conjunction with the COSEM data model and the DLMS/COSEM application layer. Data structures specific to a communication protocol are out of the Scope of this standard. Any project specific definitions of data structures and data contents may be provided in project specific companion specifications. Annex A (informative) provides information on M-Bus frame structures, addressing schemes and an encoding example. Annex B (normative) specifies COSEM interface classes to set up and manage the wired and wireless M-Bus communication channel. Annex C (informative) provides MSCs for representative instances of communication.
