Introduction
This 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).
EN 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).
EN 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 CEN/TR 17167 that provides examples and
supplementary information related to EN 13757-2, EN 13757-3 and EN 13757-7.
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.
This standard 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.
The European Committee for Standardization (CEN) draws attention to the fact that it is claimed that
compliance with this document may involve the use of a patent concerning Forward Error Correction
given in 12.8.

5.1 Modes of operation
The “meters” may communicate with “other” system components, for example mobile readout devices,
stationary receivers, data collectors, multi-utility concentrators or system network components. Such
devices are in this document named “Other Device”. For the meter side, it is assumed that the
communication function will work without any operator’s intervention or need for battery replacement
over the full lifetime of the radio part of the meter. Other components such as the mobile readout or
stationary equipment may have a shorter battery lifetime or require an external power supply as
dictated by the technical parameters and use.
Several different modes of operation are defined for the communication with the meter. Many of the
physical and link layer parameters of these different modes are identical, allowing the use of common
hardware and software. However, due to the operational and technical requirements of these modes
some parameters will differ.
The name of a mode is specified by a letter and a number. The letter specifies a mode and the number
specifies whether the modes supports unidirectional (= 1) or bidirectional (= 2) data transfer.
a) “Stationary mode”, mode S is intended for unidirectional or bidirectional communications between
the meter and a stationary or mobile device. A special transmit only sub-mode S1 is optimized for
stationary battery operated devices with a long header and the sub-mode S1-m is specialized for
mobile receivers.
b) “Frequent transmit mode”, mode T. In this mode, the meter transmits a very short frame (typically
3 ms to 8 ms) every few seconds, thus allowing walk-by and/or drive-by readout.
Transmit only sub-mode T1. It is the minimal transmission of a meter ID plus a readout value,
which is sent periodically.
The bidirectional sub-mode T2 transmits frequently a short frame containing at least its ID and
then waits for a very short period after each transmission for the reception of a response. The
reception of a response will open a bidirectional communication channel. Alternatively, the initial
frame contains the readout value as well, and the response is a reverse channel only used for
special services.
c) “Frequent receive mode”, mode R. In this mode only R2 is relevant, as R1 makes no sense. The
meter listens every few seconds for the reception of a wakeup message from a mobile transceiver.
After receiving such a wakeup, the device will prepare for a few seconds of communication dialogue
with the initiating transceiver. In this mode a “multi-channel receive mode” allows the
simultaneous readout of several meters, each one operating on a different frequency channel. This
mode is as well applicable to stationary Other Devices.
d) “Compact Mode” mode C. This mode is similar to mode T but it allows for transmission of more data
within the same energy budget and with the same duty cycle. It supports the sub-modes C1 and C2
for unidirectional and bidirectional devices. It is suitable for walk-by and/or drive-by readout. The
common reception of mode T and mode C frames with a single receiver is possible.
e) “Narrowband VHF”, mode N. Optimized for narrowband operation in the 169 MHz frequency band,
allocated for meter reading and a few other services. The range of sub-modes can be extended
using repeaters. Sub-band A is intended for, but not limited to, long range secondary
communication using multi-hop repeaters.
f) “Frequent receive and transmit mode”, mode F. Used in the 433 MHz frequency band for long range
communications. In the bidirectional sub-modes F2-m, the meter listens every few seconds for the
reception of a wake up message from a stationary or mobile transceiver. After receiving such a
wake up message, the device prepares for a few seconds of communication dialogue with the
initiating transceiver. The bidirectional sub-mode F2 transmits a frame and waits for a short period
for the reception of a response. The response will open for bidirectional communication.
Meters or other communication devices may support one, multiple or all of the described modes.
NOTE Additional modes, supporting repeating and routing of data, are specified in EN 13757-5.
The detailed handling of broadcast and multicast transmissions is not specified in this standard. The
transmission shall be interpreted as multicast if no Extended Link Layer or Transport Layer is used.
