European foreword
This document (prEN 13757-3:2023) has been prepared by Technical Committee CEN/TC 294
“Communication systems for meters”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13757-3:2018.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
This document falls under Mandate EU M/441 “Standardisation mandate to CEN, CENELEC and ETSI in
the field of measuring instruments for the development of an open architecture for utility meters
involving communication protocols enabling interoperability” by providing the relevant definitions and
methods for meter data transmission on application layer level. The M/441 Mandate is driving significant
development of standards in smart metering.
EN 13757-3:2023 includes the following significant technical changes with respect to EN 13757-3:2018:
— Support of sensor devices and alarm devices in new subclause 6.5 and Table 13;
— add new Table 14 - Bit field definition of “Installation conditions”;
— mark unused VIF/VIFE in Table 10 and Table 12 as deprecated;
— extend coding of message application in Table 26;
— add alternative non-metric units in Annex C;
— revision of the clock synchronisation protocol in Annex E.3.
EN 13757 is currently composed with the following parts:
— Communication systems for meters — Part 1: Data exchange;
— Communication systems for meters — Part 2: Wired M-Bus communication;
— Communication systems for meters — Part 3: Application protocols ;
— Communication systems for meters and remote reading of meters — Part 4: Wireless meter readout
(Radio meter reading for operation in SRD bands);
— Communication systems for meters — Part 5: Wireless M-Bus relaying;

Introduction
This document belongs to the EN 13757 series, which covers communication systems for meters.
EN 13757-1 contains generic descriptions and a communication protocol. EN 13757-2 contains a
physical and a link layer for twisted pair based Meter-Bus (M-Bus). EN 13757-4 describes wireless
communication (often called wireless M-Bus or wM-Bus). EN 13757-5 describes the wireless network
used for repeating, relaying and routing for the different modes of EN 13757-4. EN 13757-6 describes a
twisted pair local bus for short distance (Lo-Bus). EN 13757-2 describes transport mechanism and
security methods for data. The Technical Report CEN/TR 17167 contains informative annexes for
EN 13757-2, EN 13757-3 and EN 13757-7.
These upper M-Bus protocol layers can be used with various Physical Layers and with Data Link Layers
and Network Layers, which support the transmission of variable length binary transparent messages.
Frequently, the Physical and Link Layers of EN 13757-2 (twisted pair) and EN 13757-4 (wireless) as well
as EN 13757-5 (wireless with routing function) or the alternatives described in EN 13757-1 are used.
These upper M-Bus protocol layers have been optimized for minimum battery consumption of meters,
especially for the case of wireless communication, to ensure long battery lifetimes of the meters.
Secondly, it is optimized for minimum message length to minimize the wireless channel occupancy and
hence the collision rate. Thirdly, it is optimized for minimum requirements towards the meter processor
regarding requirements of RAM size, code length and computational power.
An overview of communication systems for meters is given in EN 13757-1, which also contains further
definitions.
This document concentrates on the meter communication. The meter communicates with one (or
occasionally several) fixed or mobile communication partners which again might be part of a private or
public network. These further communication systems might use the same or other application layer
protocols, security, privacy, authentication, and management methods.
To facilitate common communication systems for CEN-meters (e.g. gas, water, thermal energy and heat
cost allocators) and for electricity meters, in this standard occasionally electricity meters are mentioned.
All these references are for information only and are not standard requirements. The definition of
communication standards for electricity meters (possibly by a reference to CEN standards) remains
solely in the responsibility of CENELEC.
