European foreword
This document (prEN 13757-4:2017) 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 13757-4:2013.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
The main changes since EN 13757-4:2013 are as follows:
— referenced standards have been updated to the most recent versions;
— Mode N, in the 169 MHz band has been extended to cover more frequencies see Clause 10;
— new C-field function code (Send User Data - No reply) added see 12.5.4;
— optional Forward Error Correction in the Link Layer added see 12.8;
— CI field for selectable Extended Link Layer added see 13.2;
— management functions for link control added see Clause 14.
The standard is not affected by any of the requirements in Directive 2004/22/EC as it only covers the
basic transmission of information from the meter to an external entity. The standard ensures that data
transmitted cannot be modified without it being detected. Confidentiality, integrity and authenticity are
provided by the capabilities specified in other part of the EN 13757 series of standards. The standard
does not specify any of the metering capabilities of the meter nor the metrological capabilities of the
meter.
The standard enables encrypted transfer data either directly or as specified in other parts of the
EN 13757 series of standards. The encryption ensures the confidentiality of any personal data.
The standard provides capabilities of interoperability of meters as requested in M/441 which can be
used to improve the customer awareness of actual consumption.

Introduction
This draft European Standard 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).
prEN 13757-3 describes the application layer protocols (often called M-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).
prEN 13757-7 describes transport and security services.
These upper M-Bus protocol layers can be used with various physical layers and with 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.
The different parts of this standard are complemented by FprCEN/TR xxxxx that provides examples and
supplementary information related to prEN 13757-3 and prEN 13757-7.
These upper M-Bus protocol layers have been optimized for minimum
