1 Functional description
The PadPuls M1 serves for the adaptation to the M-bus system of consumption
measuring instruments, such as, current, gas or water meters. However, the meters to
be adapted must have a floating pulse output. The user can configure the PadPuls M1
with the MBCOPNF program so that the scanned impulses are converted to units such
as kWh, m3, J and so on. The configuration is very easy with the MBCONF user
interface.
When connected to the M-bus the PadPuls M1 is powered from the bus. A built-in
battery ensures that metering continues even if the M-Bus fails for longer than the
normal calibration time for the water meter or heat counter. The battery also ensures
that the meter readings and the configuration data is maintained in RAM. The battery
jumper should therefore be plugged in at all times. The jumper serves only to
disconnect the battery from the circuitry should the battery need to be replaced.
Device data can be protected against unauthorized configuration. The PadPuls M1 can
be switched to protection mode with a special M-Bus telegram. Subsequent changes to
device parameters cannot be made in this operating mode. The protection mode can
then only be disabled by opening the sealable housing and pressing the unprotect
pushbutton.

2 Installation and startup
2.1 Mounting the case
The housing is fixed to the wall with two
screws, which are screwed diagonally
through the holes marked with “wall”.
The heads of the screws should be
maximum 6 mm in diameter so that the
cover is not screwed as well.
2.2 Opening the case
To deactivate the write protection the housing cover can be opened by removing the
metal screws above at the left and below at the right. The unprotect pushbutton is then
accessible from outside; the unit is unprotected by pressing this button.
Use a suitable adhesive seal to prevent the housing from being opened unnoticed.

After opening the housing please lead the M-Bus cable through the left cable gland of
the cover and connect the cable to the left terminal. Then do the same with the cable of
the pulse generator (right side). Please connect an optional shielding to the terminal
labeled with „Schirm“. Connect the shielding only at the PadPuls.
•Impulse devices with floating contacts (reed contacts) are connected to the terminals
marked with “pulse” using any polarity. If cable shielding is available, it can be wired
single-sided to the terminal marked with “shield”.
•Impulse devices with optocouplers or electrically isolated transistor outputs must be
connected to the “pulse” with the correct polarity. The left-hand terminal is the
positive connection and the middle terminal the negative connection.

3 Parameterization using MBCONF
The configuration of the device must be adapted by the customer to the respective
installation. We include the software MBCONF with delivery. You can get the old
software PADCON for MS DOS or MS Windows 3.1 systems from our web page
www.relay.de.
3.1 Installation
The software MBCONF for configuration of the pulse adaptor is a 32-bit application,
which can be executed on IBM-PC compatible computers under the operating systems
Windows 95 / 98 / NT 4.0. The desktop PC or laptop must have a free serial RS232C
interface to connect the M-Bus level converter. The PadPuls M1 to be parameterized
must be connected directly (i.e. as only M-Bus device) to the M-Bus output of the level
converter.
Please start the file “MBCONF_SETUP.EXE” from Windows Explorer or via “Start
Execute” to install the software from version 1.40 up. Subsequently you select the
language of the installation procedure. The setup software can create a program group
and a link on the desktop on demand. You can then execute both versions for German
and English language either from start menu or desktop.
3.2 Operation
After program start the user operates the software according to the Windows
conventions with the mouse or the keyboard. If you stay with the mouse on a button or
an input field, then a hint to its function appears. Light-grey fields and boxes are not
capable for editing.
All input fields and buttons have an underlined letter. The function can be activated by
simultaneous pressing of the keys [ALT] and the respective letter. Within dialogs the
cursor can be moved with the keys [TAB] or [SHIFT][TAB ] forwards and back.
[SPACE ] activates or deactivates selection boxes. Multiple selection boxes (arrow at
the right edge) can be activated with [⇓]. The user then selects an entry with [⇓] and [⇑].
By pressing [RETURN] the selected entry is taken over. With [ESC] the selection box is
left without transfer.
The program is arranged as a sheet system. The sheet “Info” contains general options
of the communication with the M-Bus device to be configured. In this sheet the user can
select the serial port of the PC, the baudrate of the PC, the baudrate of the M-Bus
device and the M-Bus primary address which is used for communication. After a
successful connection with the M-Bus device, further manufacturer information is shown
in the sheet “Info” and additional device-specific sheets are displayed.

3.3 Sheet Info
This sheet shows some photos of supported M-Bus devices from the product range of
the Relay GmbH, the PadMess GmbH and further manufacturer. Here are also links to
the Internet page, from which the current version of the program can be downloaded,
and to the email address for criticism and suggestions to the program.
The lower third of this card is likewise visible in every other card. Here the following
input fields and buttons are always attainable:
COM-Port is the serial port of the PC to which the M-
Bus level converter is
connected. The selected port will be saved in an INI file and will be
restored on startup. Therefore the COM-
Port has to be configured
only once.
Baudrate
ist the transmission speed of the serial port of the PC used for
parameterization. Possible selections for this used M-
Bus baudrate
are 300, 2400 or 9600 baud. Attention: Baudrates of more than
2400 baud are not supported by all M-Bus level converters whic
h
are available on the market! The selected baudrate must be

PadPuls M1 User Manual 26.09.01, Version 1.3 7
GmbH, Stettiner Str. 38, D-33106 Paderborn
identical to the baudrate of the M-Bus device. (see: “New M-
Bus
Baudrate”). The PadPuls M1 supports the baudrates 300, 2400 and
9600Bd.
New M-Bus
Baudrate
allows reprogramming the baudrate of the M-
Bus device. The new
baudrate is sent to the M-
Bus device after a change in the
appropriate selection box. If the M-
Bus slave accepts this
command, it acknowledges the telegram with the single character
„$E5“ ($ for hexadecimal notation) using the old
baudrate.
Afterwards the de
vice switches to the new baudrate. This button is
not needed for the PadPuls M1, since it automatically detects the
baudrate used by the master.
M-Bus Address is the primary address of the connected M-
Bus slave. In a direct
con
nection with only one slave you can use the broadcast address
254. Using this address every M-
Bus device must answer
regardless of its own address.
Connect
to meter
is used to request data from the slave. The type of device is then
automatically recognize
d. The items “Manufact.”, “Generation”,
-
Bus State” will then be refreshed. New sheets are
generated depending on manufacturer and type of the M-
Bus
de
vice. In case of PadPuls M1 a sheet labelled with “PadPuls M1”
appears.
Manufact. is an item that shows the 3-
letter manufacturer code after
successful reading (“Connect to meter”). The item is read only.
Generation shows the software revision of the firmware of the connected M-
Bus device. The item is read only.
Type shows the type (here: PadP
uls M1) of the connected device. This
item is read only.
M-Bus State shows the M-
Bus state of the connected device. This item is read
only.
ZVEI optical
mode
If this option is activated, devices with an optical interface and
protocol according to EN 1434-
3 can be read and programmed
using an optical reading head (e.g. PadPuls M4 / M4L).
Autom.readout
The software always reads the data after writing, if this option is
activated (useful for checking the correct programming).

GmbH, Stettiner Str. 38, D-33106 Paderborn
Log-Window
The so-called log window is always visible. All M-Bus communication steps are logged
in this window. Data is displayed in hexadecimal notation. It is possible to mark outputs
in the log window and copy them with the keys “CTL-C” to the windows clipboard. Then
the data can be easily imported to any text editor for documentation. As soon as the
max. storage capacity of the window is achieved, no more data is logged. If you want to
log further, you must delete the logged data.
The following buttons are also always visible:
Erase log clears all outputs inside the log window.
Exit
terminates the program and stores the current setting of serial port
(port no.) into the INI file.

3.3 Sheet PadPuls M1
These sheet shows the actual settings and values of the PadPuls M1. The following
input boxes and buttons are used to change the params of the pulse adapter:
Primary address is the M-
Bus address of the device. Values between 1 and 250 can
be entered in this field for new assignment of the address. After
pressing t
he “Write” button the software programs this primary
address and further variable settings on this sheet into the M-
Bus
device.
ID (sec. adr.) is the 8 digit M-
Bus ID (identification no.), which is also used for
secondary addressing of this adapter.
Fabric. no. is insignificant for PadPuls M1.
Medium
describes the measured medium of the connected meter.
Examples: Oil, Water, Heat, Electricity

Multiplicator
is the pulse increment (multiplicator) of the connected meter. For
each registered pulse the
device adds “multiplicator” to the counter.
The nu
merator can take values between 0 (no counting) and 255,
the denominator between 1 and 255.
Unit
is the physical unit of the counter and of the pulse increment. All
proper units including variants with p
ower of ten from the DIN EN
1434-3 are offered in the selection list.
Counter
is the accumulated counter. It has to be related to the unit
men
tioned above. The counter can be programmed equal to the
counter of the connected meter in a range of 0 to 0 to 1x1012
or in
detail 1.099.511.627.775 ( = 00 FF FF FF FF FF hex.).
State is the M-Bus state in hexadecimal notation.
Write protection
is marked, if the device is protected against programming. Then
you cannot configure the adapter. The protection can be r
emoved
after opening the sealable front cover of the housing and pressing
the “Unprotect” pushbutton.
Permanent error is insignificant for the PadPuls M1.
Writeprotect
Transmits a command to the PadPuls M1 to activate write
protection. The PadPuls then
allows no further configuration. It is
protected against unnoticed manipulation.
Read reads the M-
Bus device and refreshes the data on the selected
sheet.
Write
sends the current options to the pulse converter, which stores this
data into the battery bu
ffered memory. The PadPuls M1 changes
the options only if the write protect is deactivated. It is
recommended to read the data after writing and check it.
