1 Summary

M-Bus is recognized in many regions of the world as a basis for new advanced metering infrastructure (AMI)

installations. Their wireless implementation brings a competitive advantage; also they are products easy to install

and maintain. The Wireless M-Bus standard (EN 13757-4:2005) defines the wireless communication between meters

for water, gas, heat and electricity, and the data concentrators. The stzedn stack implements the protocols for

Wireless M-Bus. It has demonstrated its interoperability with modules of well-known manufacturers on the different

protocol layers and is compliant with the current Wireless M-Bus standard [4]. It is an optimised solution between

small footprint and excellent modularity and scalability.

This document describes a demonstration software based on the stzedn protocol stack for Wireless M-Bus.

2 Wireless M-Bus Basics

2.1 Introduction

The Metering Bus (or in short "M-Bus ") is a field bus, which is specialized for transmitting metering data from gas,

heat, water or other meters to a data collector. It is described by European Norm (EN 13757), which includes the

specification of wired and Wireless M-Bus. The specification is divided into five parts:

• EN 13757-1 ([1]):

Communication systems for meters and remote reading of meters - Part 1: Data exchange

The first part describes the basic communication between the meters and a central data collector. It provides

an overview of the communication system.

• EN 13757-2 ([2]):

Communication systems for meters and remote reading of meters - Part 2: Physical and link layer

This part includes the specification of the physical data transmission using wired connections. It also includes

the description of the protocol to transmit the data.

• EN 13757-3 ([3]):

Communication systems for meters and remote reading of meters - Part 3: Dedicated application layer

The third part of M-Bus describes an application protocol, which allows the data transmission of meters’

multivendor capability. So devices of different manufacturers may be combined in one system.

• EN 13757-4 ([4]):

Communication systems for meters and remote reading of meters - Part 4: Wireless meter readout (Radio

meter reading for operation in the 868 MHz to 870 MHz SRD band)

This part specifies the wireless communication of M-Bus and is the main source document for this implemen-

tation. It includes the Physical and the Data Link Layer for wireless devices, and it corresponds to specification

EN 13757-2 for wired communication.

• EN 13757-5 ([5]):

Communication systems for meters and remote reading of meters - Part 5: Relaying

This last part includes different proposals for relaying the meter data to overcome the range problem between



remote meters and data collectors.

The sixth part of this norm relates only to wired busses and is disregarded in this document.

All parts of EN 13757 are compilant to the European Norm EN 870-5 [8].

2.2 Protocol Stack

2.2.1 Introduction

M-Bus is compatible to the international ISO/OSI-model, but only the layers 1, 2 and 7 are implemented.

Layer 7 Application Layer (EN 13757-3)Layer 2 Data Link Layer (EN 13757-2 or EN 13757-4)Layer 1 Physical Layer (EN 13757-2 or EN 13757-4)

Table 1: Operating Modes of Wireless M-Bus

Up to now, the application layer implements all other protocol layers required for a specific appliance. Especially if

routing is required according to [5], it resides on the application layer. This lack of modularity might be one reason

why standardized routing algorithms are currently not available for Wireless M-Bus. But the reduced modularity

leads to compact implementations running on very small devices with minimum computing ressources. The M-

Bus favours asymmetric network topologies with low-cost or low-power metering devices on the one side and data

collectors or gateways with higher performance on the other side. Currently, only point-to-point or star network

topologies apply. Mesh networking is not possible, as the required routing algorithms are not specified yet. This

chapter describes the settings for common implementations of the data collector and the metering devices to setup

a network in star topology.

2.2.2 Communication Modes

Based on the appliance, there are combinations of communication modes for data collectors and metering devices.

These settings define the communication flow and the configuration of the radio channel. Table 2 lists available

communication modes.



Mode Communication Description

S1 Unidirectional In the stationary mode, the metering devices send their data several times a day.In this mode, the data collector may save power as the metering devices send awakeup signal before transmitting their data.

S1-m Unidirectional Same as S1, but the data collector must not enter low-power mode.S2 Bidirectional Bidirectional version of S1.T1 Unidirectional In the Frequent Transmit mode, the metering devices periodically send their data

to collectors in range. The interval is configurable in terms of several seconds orminutes.

T2 Bidirectional Bidirectional version of T1. The data collector may request dedicated data fromthe metering devices.

R2 Bidirectional The Frequent Receive mode permits multiple metering devices not to interfere dueto frequency multiplexing.

Table 2: Operating Modes of Wireless M-Bus

Table 3 lists the combinations of the communication modes of meters and data collectors.

In T2 mode, the communication settings for the two data directions are different. Due to deviant requirements, both

communication devices have to support fast switching of communication speed, coding scheme, and frequency.

Table 3: Compatibility matrix for Wireless M-Bus operating modes

The table above shows that although the T- and S-modes cannot be combined, a T2 data collector may interfere with

a parallel S-mode communication.



2.2.3 Unidirectional vs. Bidirectional Communication

If unidirectional communication is used, data is only sent from the metering device to the data collector. This

enables simple transmitters as metering devices while the data collector only needs to receive. Becaus listen-before-

talk (LBT) and dynamic network configuration are not possible using unidirectional communication, it only applies

for static communication with little load.

In a bidirectional communication, there are three ways to exchange data between a meter device and a data collector:

1. meter device sends Access Demand Requests (AD Req) periodically to be detectable for data collectors. If

a data collector wants to open a bidirectional communication channel, it sends an Acknowledgement (ACK)

frame. When receiving an ACK, the meter device stops sending AD Req, and it waits for the data collector

to send a User Data Request. The requested data are transmitted in a User Data Response packet, and the

meter devices continues the periodical transmission of Access Demand Requests. This lean protocol requires

little resources on the metering device. The communication flow, which applies in T2 communication mode,

is illustrated in Fig. 1.

Figure 1: Bidirectional Communication Mode T2

2. It is also possible that the meter device sends its meter data periodically. This is the case in mode S2. In

this mode, a bidirectional communication will only be established if further data or commands needs to be

exchanged (cf. Fig. 2). After the channel setup, the communication is identical to case 1. Fig. 2 shows a usual

communication flow.



Figure 2: Bidirectional Communication Mode S2

3. In R2 mode, the meter device is listening periodically for a waking preamble sent within a request packet.

If such a request has been received, the channel will be established according to case 1 (mode T2). If no

communication is required, the meter device enters sleeping mode. Therefore, the data collector

• has to know the approximate time, when the meter device enters listening mode, and

• it has to send the wakeup packets several times if the meter device does not respond.

Figure 3 shows an example communication flow in R2 mode.

Figure 3: Bidirectional Communication Mode R2



2.3 Available Software Configurations and Documentation

The demonstration application demonstrates only a few possibilities of the complete stack functionality. For instance,

the stack can be used like a modem that serially connects to the customer´s application. An AT command set is used

to set up and run the Wireless M-Bus network. In this case, programming the module is not necessary since the device

is preconfigured. A binary non-readable command set is also available to minimize the communication overhead. If

the stack is used as modem, it is exclusively used for communication tasks.

For applications that are sensitive e.g. concerning the energy consumption or cost, often only one microcontroller is

used for both: The communication and the sensor application. In these cases, the protocol stack can be purchased as

library or as source code in different software packages. Please contact [email protected] for a quotation. Refer

to Table 4 for a list of available software packages.

Customizations of the stack as well as customer specific applications are possible upon request.

2.4 Working with the different software configurations

As shown in Table 4, Multiple approaches exist when using the protocol stack.

1. Verify the devices:

Prior to the development of custom applications, the hardware should be checked to work properly using the

demo application.

Monitoring the radio communication helps not only during the first steps of wireless networking. Amongst

others, chapter 4.2 presents a sniffer tool for Wireless M-Bus.

2. Using the device as a modem:

In the modem-like configurations, a dedicated M-Bus firmware is loaded to the radio board as integral binary

file. No custom firmware is runnning on the radio board, but the radio communication is controlled using a

serial interface. An AT command set known from modems eases the configuration.

• The chapters 3.1 and 3.2 are for reference purpose only. They contain the description of the functions

called by the library, and they can be omitted if the relevant standards are at hand.

• Chapter 3.3 explains the AT parser’s structure and commands. For each specific command, the cross

reference to the concerning library functions is provided. Start from this chapter when running the radio

board as a modem.

By default, the hardware modules are shipped with a modem application so that no debug adaptor is required

to run the devices. This firmware even contains the test modes required for radio equipment certification.

3. Using the library for the communication:

Using this approach requires a professional license of an Integrated Development Environment (IDE) to com-

pile and run the firmware. As the library provides an abstraction layer for the radio communication and

parts of the hardware functionality, please continue with the following sections for correctly using the library

funtionality.

2.5 Library interaction

2.5.1 Introduction

This chapter informs about the different libraries and the opportunities to include them into custom firmware.

Example projects for the most common Integrated Development Environments (IDE) shall help to configure the

devices correctly for the network application.



2.5.2 IDE Projects

The software will be shipped including project files for the following IDEs:

• IAR Embedded Workbench for MSP430

• Code Composer Essentials (CCE)

The project files provide a fully pre-configured demo-application-environment for building a demo application ac-

cessing the appropriate stack-library. The structure of the source file directory should not be modified, as long as

the IDE project files are not adapted accordingly to the modifications. The structure of the directory containing the

source files looks like this:

• Demo Application

– Meter

∗ app_demo_apl_meter.c

∗ app_demo_dll_meter.c

– Collector

∗ app_demo_apl_collector.c

∗ app_demo_dll_collector.c

• Wireless M-Bus

– Includes

∗ applicationlayer_api.h

∗ datalinklayer_api.h

∗ hal_api.h

– Libraries (The delivered libraries depend on the license)

∗ wmbus_lib_apl.r43/.lib

∗ wmbus_lib_dll.r43/.lib

∗ wmbus_lib_.... .r43/.lib

For first steps on hardware, the IDE needs to be configured for usage of the appropriate debugger!



2.5.3 Libraries to include

In order to save resources and to increase the performance of the application the stack is available in several libraries.

The choice of a suitable library depends on the application and the requirements. There are three design parameters

composing the required library:

Design parameter "Top layer" Description

APL The stack includes all layers and can be accessed via "apl_-functions".DLL The stack includes all layers up to the datalink layer (no application layer)

and can only be accessed via "dll_-functions".

Table 5: Design parameter "Top layer"

Design parameter "device" Description

Meter The stack only includes functionality for meter devicesCollector The stack only includes functionality for collector devicesboth Functionality of the stack includes meter and collector devices and may be

chosen during runtime (requires more resources).

Table 6: Design parameter "device"

Design parameter "Mode" Description

S1/S1-m/S2/T1/T2/R2 The stack uses either the S1, S1-m, S2, T1, T2 or R2 mode for transmis-sion/reception.

all The mode to be used by the stack may be chosen during runtime (requiresmore resources).

Table 7: Design parameter "Mode"

2.5.4 The hardware abstraction layer

The stack uses a slight HAL which covers the hardware resources required by the stack. This is to avoid crashing the

stack due to misconfiguration of required resources. The resources required by the stack are:

• One timer (ms resolution).

• The appropriate pins in order to access an externally connected transceiver.

• Access to an exclusive non-volatile data memory (e.g. info flash in case of TIs MSP430-series, EEPROM, ...)

The following approach is strongly recommended in order to avoid crashing the stack:

First of all it is recommended to read the API documentation of the HAL before accessing periphals of the micro-

controller. This is to verify, if the appropriate hardware/periphery is already abstracted by the HAL. In case it is

abstracted, it is strongly recommended to use the API function in order to avoid an unpredictable behaviour of

the stack! In case the periphery is not mentioned within the API documentation, it is safe to directly access the

peripherals as documented by the microcontroller manufacturer.


3 CONFIGURATIONS page 15

2.5.5 API function calls

The libraries are shipped with some header files. However, the following two header files must be included:

• applicationlayer_api.h resp. datalinklayer_api.h: For accessing the stack on its top layer and for prototypes of

the callback routines to be implemented by the application.

• hal_api.h: For accessing the HAL and for the prototype of the watchdog expiration callback.

All functions prototyped by the API header files may be used to access the stack or the HAL. All function prototypes

of callbacks must be implemented within the application. Otherwise the compiler will break and report an error.

2.5.6 Watchdog handling

Deterministic networking can only be guaranteed if the main application does not block for seconds while waiting

for events. To disclose this class of errors, the protocol stack implements watchdog handling. In order to ensure

correct watchdog triggering, it is required to call apl_run() resp. dll_run() regularly.

In case the watchdog expires, the appropriate ISR will jump to the callback function as prototyped by hal_api.h and

implemented by the application.

3 Configurations

3.1 Data Link Layer

In [4] the parameters for the phyiscal layer and the data link layer are specified.

The API of the stzedn implementation includes functions which are used to send and receive data telegrams via the

Wireless M-Bus protocol.

It can be used for the M-Bus application layer specified in [3] or a manufacturer specific application layer.

3.2 Application Layer

In [3] an application layer for Wireless and Wired M-Bus is specified.

This application layer is used for manufacturer independent data transfer.

The API of the stzedn implementation provides functions for sending and receiving data records as specified in [3].

3.3 AT Parser

The serial parser is intended to provide access to the functions of the data link layer and the application layer of

Wireless M-Bus specified in chapters 3.1 and 3.2 using a serial interface. The purpose of this interface is to connect

a PC or a host controller, and to use the module like a modem, without accessing the module’s firmware.


4 ADDITIONAL TOOLS AND FURTHER OPTIONS page 16

There a two different configurations for this parser. First, an AT-interface based on readable ASCII symbols, and

second, a binary interface. The AT-interface is intended for PC connection using a console. It combines multiple

commands of the binary interface to easily start communicating over Wireless M-Bus. The binary interface provides

access to every single function of data link layer or application layer, and thus optimizes the firmware access. This

version is intended to connect a host controller, and it eases the migration from using a module for communicating

to the implementation of the protocol stack in the former host controller.

4 Additional tools and further options

4.1 Introduction

The Wireless M-Bus protocol stack from stzedn can be used in different versions. Refer to chapter 2.3 for details.

Especially for large networks of some thousand meter devices and data collectors, additional tools are useful to

efficiently set up and run the network. Those tools are designed and developed by stzednand are described below.

4.2 capt2web Wireless M-Bus Monitoring and Commissioning Tool

Wireless communication benefits from commissioning tools during system setup. Once the network is operating,

errors or intrusion attempts can be logged.

Usually the network monitors require software installation on the monitoring machine. Also, in case of non-standard

protocols, additional hardware drivers are necessary to connect the sniffing module. The stzedn solution follows a

different approach. The sniffing device runs an embedded web server, to which any web browser can connect. By

default, the connection uses Ethernet but it can also be established via GPRS, modem, and Wi-Fi. Figure 4 shows

the hardware device of the stzednfor capturing data.

Figure 4: Hardware for in-field Wireless M-Bus data monitoring

Web 2.0 services implemented by the web server inside the sniffing device regularly refresh the client browser

while only transmitting the M-Bus telegrams received. Java scripts are used for telegram filtering, colouring, and

evaluation. Figure 5 shows as an example the browser window including the packets timeline. The packets shown

were catched and logged during a session of the demonstration program. Logging to USB Flash Drives and later

download logging data makes long-term tests easier. In case of questions or to ask for a quotation for the tool, please
