1 Functional description
The PadPuls M2 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. Up to two impulse meters can simultaneous be connected to the inputs of this device. Optionally the user can activate a tariff function, by which energy or volume pulses are accumulated in separate meter readings for primary and secondary tariffs. In this case a floating signal for tariff switch is used at Port 2.
Each port or each tariff of the PadPuls M2 can be read on M-Bus using its own primary and secondary address. The PadPuls M2 thus acts as two stand-alone M-Bus Slaves!
The user configures the pulse collector with the software MBCONF. The accumulated pulses are converted into kWh, m
3
, J or other physical units. The user interface of
MBCONF allows the operator to get an easy access to the configuration.
When connected to the M-Bus the PadPuls M2 is powered from the bus. A built-in battery ensures that metering continues if the M-Bus is interrupted. Two battery options are available. The version with the higher capacity allows M-Bus independent metering for several years.
Another feature of the PadPuls M2 is the due-date function. Meter data are saved separately at the preset due-date at 00:00 hour (day change to the due-date) by the implemented clock with calendar function. The due-date can be changed without lost of the already stored counters. Additionally the M-Bus Master can initiate an immediate execution of the due-date function by sending of the so-called „Freeze“ command. A
„Freeze“ sent to all pulse collectors using the broadcast address 254 is helpful for generating reading profiles of an M-Bus system. Afterwards the master software polls the data of all meters.
The complete configuration data is saved into a non-volatile memory (EEPROM).
Additional security is provided by daily saving of meter readings into this EEPROM. In case of M-Bus fail and empty battery the last saved data is restored on power up.
The configuration data can be protected against unauthorized manipulation. The
PadPuls M2 can therefore 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 sealed housing and pressing the unprotect pushbutton for minimum 4 seconds.

2 Installation and Startup
2.1 Mounting the case
The bottom part of case is first attached to the wall with the terminals arranged downward. Please use 2 screws mounted through the outside drillings at the case.
The cable for pulse generator and M-Bus interface are led through the self sealing cable glands in the housing. You should break the cable glands with a small screw driver if you use flexible cables. To ensure a high protective class of up to IP65 the hole must be much smaller than the outer diameter of the cable. If you lift the terminal connectors and feed the cables far enough through the glands, you can connect the wires comfortably outside of the housing. Afterwards please withdraw the cables again and put the terminals on the appropriate pin rows on the circuit board. The strain relief is given by looping the enclosed cable straps around the cable. If you have completed all assembly and configuration work, you should protect the device against manipulation with one sticking on each screw on the cover of the case.
The accompanying drawing defines the measures for wall mounting in mm:

GmbH, Stettiner Str. 38, D-33106 Paderborn
2.2 Activating
Coming from factory the PadPuls M2 must first be activated. The cover of the housing is to be removed. On the circuit board there is a 2pin row marked with “BAT”. Here the jumper must be put on both pins to allow battery operation and security function in case of M-Bus failure.
•
If the device is not used for a longer time, it is advisable to deactivate battery operation by removing the jumper to preserve the battery.
•
If the battery should be empty, it can be exchanged. See section 5.
The PadPuls M2 is supplied from M-Bus if it is available. In this normal state the internal battery is then not loaded. Only when the M-Bus fails the battery takes over automatically the supply. There is no lost of data and the counting function is continued. The PadPuls M2 draws approximately 1.5mA current ( one unit load) from the
M-Bus.

2.3 Connecting
The following figure shows the link of two counters with impulse outputs to the PadPuls
M2. We recommend to use 2-wire cables (twisted pair, NYM or j-Y(St)Y) with a max. length of 10m. In any case it must be noted that the total capacity of the cable plus impulse generator attached at any port may not exceed 2nF (optional 12nF with activated “extended pulse sampling”).

3 Parameterization using MBCONF
The configuration of the device must be adapted by the customer to the respective installation. The current version $40 of PadPuls M2V requires the use of the program
MBCONF for configuration. The older DOS version PADCON may not be used anymore.
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 M2 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.
PadPuls M2 User Manual 26.09.01, Version 1.2 7
3.3 Sheet Info
GmbH, Stettiner Str. 38, D-33106 Paderborn
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
Baudrate
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. 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

New M-Bus
Baudrate
2400 baud are not supported by all M-Bus level converters which are available on the market! The selected baudrate must be identical to the baudrate of the M-Bus device. (see: “New M-Bus
Baudrate”). The PadPuls M2 supports the baudrates 300 and 2400
Bd. 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 M2V, 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 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 for each channel appears in case of PadPuls
M2. The sheets are labelled “M2 Port1” for the first and “M2 Port2” for the second channel.

DD.MM.YY_hh.mm. This field can be only edited and modified in the PadPuls, if the switch “Edit and change time” is activated. The button “Read clock of PC” transfers once the current date and time of the PC into this window. The time-of-day and the date always apply to all ports of PadPuls M2. is the last due-date (date of the last storage of the due-date counter) in the format DD.MM.YY. This field is read only. is the counter which was saved at the due-date. This field is read only. is the next (future) due-date (date of the next storage of the counter) in the format DD.MM.YY. The counter will be saved at
00:00, e.g. with due-date 01.01 at change from 31th of December
23:59 to 1 st
of January 00:00. This field can be edited and programmed only, if the switch “Edit and change time” is marked.
The due-date always applies to all ports of PadPuls M2.
State of ports shows the current input state of all ports (a closed contact is marked). This item is read only.
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 housing and pressing the “Unprotect” pushbutton for a minimum of 4 seconds.
EEPROM error is marked, if there was an error while reading the non-volatile memory. In this case you must reconfigure the device.

Tariff A (P1/2)
Long pulse sampling
activates a longer charging of the contacts before sampling the inputs. This allows higher capacitors and / or many pulse generators with So interface (photocoupler with capacitors) to be connected. On delivery the extended pulse sampling is activated.
The lifetime of battery is increased for about 15% if this feature is not used.
Edit and change
activation of this check box allows editing and programming of the
time “Current time” and “Next due-date”. The checkbox is deactivated automatically after successful configuration with “Write”.
Freeze
is used for activation tariff mode on port 1 and 2. The tariff mode will be selected after pressing the “Write” button, if the check box is marked. Port 1 is then used as pulse input and port 2 is the tariff switch. With an open tariff switch the pulses are accumulated to the counter for port 1 (main tariff). With a closed tariff contact the pulses increment the counter for port 2 (special tariff). transmits a command to the PadPuls M2 telling it to freeze the counters. The PadPuls M2 then copies the current counter to the
“Due-date counter” and the current date to the (last) “Due-date”.
The storage is done for all ports simultaneously. This the same behaviour as at due-date. The freeze command can be used with the broadcast address 255 to order all PadPuls to save the current counters. Then the M-Bus master has enough time to read all meters and get values of the same time (reading profiles).
Read clock of PC once gets the current date and time from the clock of the PC and transfers it into the item “Current time”.
Write protect Transmits a command to the PadPuls M2 to activate write protect.
The PadPuls M2 then allows no further configuration. It is protected against unnoticed manipulation.
Read
Write reads the M-Bus device and refreshes the data on the selected sheet. sends the current options to the pulse converter, which saves this data into the non-volatile memory. The PadPuls M2 changes the options only if the write protect is deactivated. It is recommended to read the data after writing and check it.

GmbH, Stettiner Str. 38, D-33106 Paderborn
Notes:
1. The variables „Current time“, „Next due-date“, „Write protection“, „Long pulse sampling “ and the command „Freeze“ always apply to all ports. Therefore you need to edit these items only in one sheet. The write protect should be activated after successful configuration of all ports.
2. Please press first the button „Connect to meter“ after connecting a new M-Bus device. Afterwards all sheets are refreshed.
3. Examples for configuration of pulse increment and unit:
•
Water meter with counter = 45120 l and 1 Pulse = 10 l:
Choice 1: Unit = 10 l, Multiplicator = 1 / 1, Counter = 4512 ( x 10 l)
Choice 2: Unit = 1 l, Multiplicator = 10 / 1, Counter = 45120 ( x 1 l)
•
Electricity meter with counter = 78346 kWh and 64 pulses / kWh:
Choice: Unit = 1kWh, Multiplicator = 1 / 64, Counter = 78346 ( x 1kWh)
•
Electricity meter with counter = 112,345 kWh and 1000 pulses / kWh:
Choice: Unit = 1Wh, Multiplicator = 1 / 1, Counter = 1123454 ( x 0,001Wh)
4. With activated tariff option the pulses are evaluated with the adjustments of the respective port. Therefore you should take care that both ports have the same pulse increment and unit.
