European foreword
This document (prEN 13757-2:2018/prA1:2023) 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 amend EN 13757-2:2018.
During the review of the standard four areas of improvement were identified which are addressed in this
amendment.
In comparison with EN 13757-2:2018, the following technical modifications have been made:
a) addition of abbreviations,
b) clarification 5.7.3.1 “Normalization” regarding the FBC modification,
c) deletion of 5.7.3.4 “Status request”,
d) new 5.7.3.5 “Unsupported communication types” for handling of unsupported communication types,
e) handling of exceeded time limit in 5.7.6 “Link layer time schedule”
f) clarification of 5.7.7. “Datagram sequencing”,
g) modification of Figures 1 to 7.
EN 13757, Communication systems for meters, is currently composed of the following parts:
— Part 1: Data exchange
— Part 2: Wired M-Bus communication
— Part 3: Application protocols
— Part 4: Wireless M-Bus communication
— Part 5: Wireless M-Bus relaying
— Part 6: Local Bus
— Part 7: Transport and security services
— Part 8: Adaptation layer

1 Modification to Clause 3, “Terms and definitions”
Rename the clause from “Terms and definitions” to “Terms, definitions and abbreviations”.
Add a subclause “3.1 Terms and definitions”, renumber the term 3.1 to 3.1.2, and add the following new
term entry:
“
3.1.1
communication type
frame type as defined in EN 60870-5-2:1993 and identified by the function code
Note 1 to entry: Other parts of EN 13757 also use the term message type as an equivalent.
“.
Add another subclause “3.2 Abbreviations” after the new 3.1.2. In the new subclause “3.2 Abbreviations”
add the following:
“Abbreviation Term
FCB frame count bit
FCV frame count valid bit”.
2 Modification to 5.6, “Datagram abort on collision”
Replace
“If a slave detects at the end of a mark level send bit a (voltage) space signal from its master it shall
terminate its send datagram as soon as possible. A received continuous space signal from the master
for > 11 bit times (break signal) shall stop the datagram send of a slave not later than 24 bit times after
the start of such a break signal. For a software implementation of the byte transmission this requirement
can be met by testing the received signal state either at the end of each mark state send bit or before the
beginning of each st
