PadPuls M1
1 Functional description
The PadPuls M1 adapts consumption measuring instruments, such as, electricity, gas or water
meters to the M-Bus system. The meters that are to be adapted must have a floating pulse
output. The user can configure the PadPuls M1 with the MBCONF program so that the counted
impulses are converted to units such as kWh, m 3, J and so on. With its user interface the
configuration of MBCONF is very easy.
When connected to the M-Bus the PadPuls M1 is powered by the bus. A built-in battery ensures
that metering continues even if the M-Bus fails for longer than the normal calibration time of the
water meter or heat counter. The battery also ensures that the meter readings and the
configuration data is maintained in RAM. Therefore the battery jumper should be plugged in at
all times. The jumper serves only to disconnect the battery from the circuitry if the battery needs
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. In this operating mode, subsequent
changes to device parameters cannot be made. The protection mode can then only be disabled
by opening the sealable housing and pressing the unprotect pushbutton.

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 labelled with „shield“.
Connect the shielding only to 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 singlesided 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 device is supplied with a basic configuration (address 0, unprotected) and must be adapted
by the customer to the respective installation. Parameterization requires the MBCONF program.
You will find the free software on our CD "Tools & Docs" and for download on our homepage
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 10 / 8.1 /
7 / XP / 2000 / 98 / 95. The desktop PC or laptop must have a free serial RS232C interface to
connect the M-Bus level converter. You can alternatively use an USB or Ethernet to M-Bus level
converter with a driver for a virtual serial port. We recommend our service tool Micro-Master
USB (art.no. MR003USB). 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 run the file “MBCONF_SETUP.EXE” from Windows Explorer or via “Start – Execute” to
install the software. 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 cannot be edited.
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] forward and backword.
[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 devicespecific 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 manufacturers. Here are also links to our 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
is the transmission speed of the serial port of the PC used
parameterization. Possible selections for this used M-Bus baudrate
300, 2400 or 9600 baud. Attention: Baudrates of more than 2400 baud
not supported by all M-Bus level converters which are available on

market! The selected baudrate must be identical to the baudrate of the
M-Bus device. (see: “New M-Bus Baudrate”). The PadPuls M1 supports all
three baudrates.
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 device switches to the new
baudrate. This button is not needed for the PadPuls M1, because 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
connection 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 recognized. The items “Manufact.”, “Generation”, “Type” and
“M-Bus State” will then be refreshed. New sheets are generated
depending on manufacturer and type of the M-Bus device. A single sheet
appears in case of PadPuls M1.
Manufact.
is an item that shows the 3-letter manufacturer code after successful
reading (“Connect to meter”). This item is read only.
Generation
shows the revision connected M-Bus device. This item is read only.
Type
shows the type (here: PadPuls M1) of the connected device. This item is
read only.
M-Bus State

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 “CTRL-C” to the windows clipboard. The data can then
easily be imported to any text editor for documentation. As soon as the maximum storage
capacity of the window is achieved, no more data is logged. If you want to keep on logging, you
have to 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

3.4 Sheet M1
This sheet shows the current settings and values of the PadPuls M1. The following input boxes
and buttons are used to change the parameters of the pulse adapter:
Prim. address
is the primary M-Bus address of the selected device. Values between 1 and
250 can be entered in this field for new assignment of the address. After
pressing the “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 port.
Pre-programmed ID = YYMM + last 4 digits of serial no.
e.g. ser.no. = 15005, production date = Nov. 2017 (1711) → ID = 17115005
Fabric no.
is not used for the PadPuls M1.
Medium
describes the measured medium of the connected meter. Examples: Oil,
User Manual PadPuls PadPuls M1 · 10/2018 · VERSION 1.4

PadPuls M1
Multiplicator
Water, Heat, Electricity
is the pulse increment (multiplicator) of the connected meter. For each
registered pulse the device adds “multiplicator” to the counter. The
numerator 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 power of ten, from the DIN EN 13757-3 are
offered in the selection list. Examples: m3, kWh, MJ
Counter
is the accumulated counter. It has to be related to the unit mentioned
above. The 5 byte binary type counter can be programmed equal to the
counter of the connected meter in a range of 0 to 1x10 12 or in detail
1.099.511.627.775 ( = 00 FF FF FF FF FF hex.).
State
shows 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 removed after opening the
sealable front cover of the housing and pressing the “Unprotect” pushbutton.
Permanent Error is not used for the PadPuls M1.
Write protect
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 buffered memory. The PadPuls M1 changes the options only if
the write protection is deactivated. It is recommended to read and check the
data after writing.
