CEN/TC 294/WG 4 - Data exchange for meters on bus-systems and interface

This Technical Report contains additional information to the requirements determined in EN 13757-2, EN 13757-3 and EN 13757-7, in particular examples for the implementation, Datagram examples secured by security mechanism of part 7 and additional non-normative requirements beyond meter communication itself.

This draft European standard is applicable to the physical and link layer parameters of baseband communication over twisted pair (M Bus) for meter communication systems. It is especially applicable to thermal energy meters, heat cost allocators, water meters and gas meters.
NOTE    It is usable also for other meters (like electricity meters) and for sensors and actuators. For generic descriptions concerning communication systems for meters and remote reading of meters see EN 13757-1.

This draft European Standard specifies Transport and Security Services for communication systems for meters and remote reading of meters.
This draft European Standard specifies secure communication capabilities by design and supports the building of a secure system architecture.
This draft European standard is applicable to the protection of consumer data to ensure privacy.
This draft European Standard is intended to be used with the lower layer specifications determined in EN 13757-2, EN 13757-3, EN 13757-4, EN 13757-5 and EN 13757-6.

This European Standard specifies the general requirements and applies to heat meters. Heat meters are instruments intended for measuring the energy which in a heat-exchange circuit is absorbed (cooling) or given up (heating) by a liquid called the heat-conveying liquid. The meter indicates heat in legal units.
Part 3 specifies the data exchange between a meter and a readout device (POINT / POINT communication). For these applications using the optical readout head, the EN 62056-21 protocol is recommended.
For direct or remote local readout of a single or a few meters via a battery driven readout device, the physical layer of EN 13757-6 (local bus) is recommended.
For bigger networks with up to 250 meters, a master unit with AC mains supply according to EN 13757-2 is necessary to control the M-Bus. For these applications the physical and link layer of EN 13757-2 and the application layer of EN 13757-3 is required.
For wireless meter communications, EN 13757-4 describes several alternatives of walk/drive-by readout via a mobile station or by using stationary receivers or a network. Both unidirectionally and bidirectionally transmitting meters are supported by this standard.
