Description
AD-01 is an industrial adapter for M-bus communication. AD-01 is a very flexible
product for building of M-Bus networks. The AD-01 can be configured for a number of
applications. It is possible to access the AD-01 and activate/deactivate RS-232 and M-Bus
slave port using commands over M-Bus.
… 9-position D-sub connector (RS-232, (M-Bus))
… Data rate from 300 bit/s up to 9600 bit/s
… Automatic data rate detection
… Converter between RS-232 (M-Bus) and M-Bus networks
… Repeater
… Used to interconnect M-Bus and SIOX networks
… Zone controller
… Up to 120 M-bus slaves
… Galvanic isolated
… Designed for hash environments
AD-01 is a flexible product which implements a number of possibilities to
extend / control a M-Bus network.
AD-01 includes a micro controller (µC) which handles the data flow through the unit.
The main function is activating / deactivating of the two ports, RS-232/V.24 master and
M-Bus master which gives possibilities for the unit to work as a zone controller.
Data packets received on the slave side is passed further on the active master ports.
Data packets received on active master ports is passed further on both slave ports.
AD-01 can be addressed and configured over the slave ports.
AD-01’s master ports are active according to factory default. This means that AD-01 can
be used as a RS-232 / M-Bus converter without any external configuration.

Protocol implementation
Parts of the M-Bus protocol is implemented in the unit. Data packets which are not
addressed to the unit are transparently passed further without format or checksum
control. Packets addressed to the unit are controlled according to M-Bus standard.
Unit addressing
AD-01 can be addressed over the M-Bus protocol in two ways, by using primary or
secondary addressing.
Primary addressing
The primary address is set with switches inside the unit. See page 11, Switch settings /
Primary address.
Secondary addressing
The secondary address is based on a unique identification number in every unit. The
AD-01 secondary address is according the unit serial number and can in this way easily
be identified. The following secondary address parameters is used in AD-01
Parameter Value
ID number 10000000 + serial number*
Manufacturer WMO = 5DAF (hex)
Version Software version
Medium Bus / system = 0E (hex)
* Example: Unit with serial number 729 has ID number 10000729
Unit configuration
Some of the M-Bus protocol applications are implemented in AD-01. This makes it
possible to configure a number of internal parameters. The following applications are
implemented.
Initialisation of slave (SND_NKE)
Selection of data rate
(only if data rate using protocol is selected, see page 11, Switch settings / Data rate
functionality).
All data rates from 300 bit/s up to 9 600 bit/s can be configured according to M-Bus
standard.
Selection of slave
Selection of slave to be able to use secondary addressing. Slave select is performed
according to M-Bus standard.
Set up / Read out of master ports setting
Set up or read out of the units master ports setting is made with a specific command
sequence.

16
6612-2202
Set up of master ports
Set up of the master ports is possible using a SND_UD command, CI = 51 (hex) with
the following data field.
Data field DIF = 01 (hex) VIF = FD (hex) VIFE = E2 (hex) VIFE = 00 (hex) DATA
Description 8-bit integer Ext. coding Cont. signal Write replace Port setup
The DATA is coded according the following:
Value Master RS-232 port Master M-Bus port
00 (hex) Inactive Inactive
01 (hex) Inactive Active
02 (hex) Active Inactive
03 (hex) Active Active
Read out of master ports
Read out of the master ports setting is possible using a REQ_UD2 command. AD-01 will
respond with a RSP_UD, CI=72 (hex) with the following data field.
Data field DIF = 01 (hex) VIF = FD (hex) VIFE = E2 (hex) DATA
Description 8-bit integer Ext. coding Cont. signal Port setup
The DATA is coded according the following:
Value Master RS-232 port Master M-Bus port
00 (hex) Inactive Inactive

02 (hex) Active Inactive
03 (hex) Active Active
Error indication
AD-01 includes possibilities to alert the supervision system of short-circuit or overload
on the M-Bus master interface. Readout of error status can be made using a REQ_UD2
command. AD-01 uses the status field in a RSP_UD answer sequence to alert possible
errors.
The coding of the status field is according to the following:
Value status field Description
00 (hex) No error
10 (hex) Overload / short-circuit of
M-Bus master interface

Program update
A software update can be made using the 9-position D-sub connection. AD-01 has a
micro controller with flash memory which can be reprogrammed.
To perform a program update a program file from Westermo and flash software is
necessary.
Set up of AD-01 for program update
1. Connect AD-01 to computer serial interface.
Observe that the connection must be to AD-01 9-position D-sub.
2. Set AD-01 in flash mode, S2:2 OFF, S2:3 ON.
Observe, power must be removed before switch setting.
Set up of flash program
After installation and start the following window will appear on screen.
1. Choose ”Set Environment” and select serial port.
2. Choose ”Target Microcontroller” as MB90F497/G.
3. Choose ”Crystal Frequency” as 4 MHz.
4. Choose ”Open” and select program file.
5. Choose ”Full Operation”.
6. Control that the programming is completed without errors.
7. Remove power to AD-01
8. Set AD-01 in normal operation, S2:2 ON, S2:3 OFF.
9. Reconnect power to AD-01.

Application example
AD-01 is an industrial adapter for M-Bus communication. AD-01 is a flexible product for
building of M-Bus networks. The unit is equipped with two RS-232/V.24 interfaces, one
M-Bus master and one M-Bus slave interface. The AD-01 can be configured for a number
of applications.
AD-01 as converter RS-232 to M-Bus
AD-01 can be used as a converter between RS-232 and M-Bus. The M-Bus master inter-
face can drive up to 120 slave loads.
Consider the following points.
• AD-01 can be used transparently, no addressing or set up of AD-01 using the M-Bus
protocol is necessary.
• The primary address should be set to 0 to avoid addressing of the AD-01 unit.
AD-01 as repeater
AD-01 can be used as repeater for M-Bus. The M-Bus master interface can extend the
network with up to 120 new slave loads.
Consider the following points.
• AD-01 can be used transparently, no addressing or set up of AD-01 using the M-Bus
protocol is necessary.
• The primary address should be set to 0 to avoid addressing of the AD-01 unit.

AD-01 and connection to SIOX networks
AD-01 can be used to connect a M-Bus network to a SIOX network.
Consider the following points.
• AD-01 can be used transparently, no addressing or set up of AD-01 using the M-Bus
protocol is necessary.
• The primary address should be set to 0 to avoid addressing of the AD-01 unit.
• AD-01 should only be used in datarate using protocol mode since autobaud is not
possible when receiving SIOX commands.
AD-01 to extend a network with a modem link
Two AD-01 units can be used to extend an existing network with any type of modem
link.
Consider the following points.
• AD-01 can be used transparently, no addressing or set up of AD-01 using the M-Bus
protocol is necessary.
• The primary address should be set to 0 to avoid addressing of the AD-01 unit.
• Observe that if a dial-up modem is used the supervision system needs to send dial
commands to the modem. The supervision system must also control that a link is
established before sending data over the link.

• AD-01 can be addressed with primary or secondary address
• If meters with different data rate is used the AD-01 should be set up for autobaud.
