However, the meters to be adapted must either have a floating pulse output or an ouput according to DIN 43864 (S0). Only for usage of the S0 interface a power supply of 12V to 27VDC is necessary. The user can configure the PadPuls M1C with the MBCONF program so that the scanned impulses are converted to kWh, m3, J and other units. The configuration is very easy with the MBCONF user interface. When connected to the M-Bus the PadPuls M1C 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 M1C 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 26.09.01, Version 1.3 PadPuls M1C User Manual GmbH, Stettiner Str. 38, D-33106 Paderborn 2 Installation and startup 2.1 Mounting the case On the rear side of the housing there is a special mechanism for fixing the device on a rail TS35 according to DIN EN 50022. Please pull the mechanism to the open position using a small screw driver. When you press the device onto the rail the mechanism automatically snaps in. Please ensure that the case is mounted with the the serial no. label on the top side. 2.2 Opening the front cover To deactivate the write protection the front cover of the housing cover can be removed by use of a small screw driver. The unprotect pushbutton is then accessible from outside; the unit is unprotected by pressing this button. Attention: Afterwards please fix the cover oriented with the notch at the top. You can use a suitable adhesive seal to prevent the housing from being opened unnoticed. 2.3 Connecting The following picture shows a typical installation including the PadPuls M1C: level converter PC -Bus power supply 24V + - PadPuls M1C PadPuls M1C User Manual 26.09.01, Version 1.3 3 GmbH, Stettiner Str. 38, D-33106 Paderborn • The M-Bus is connected polarity independent to the terminal “M” and “M”. • Impulse devices with floating contacts (reed contacts) are connected to the terminals marked “P-“ and “P+” using any polarity. If cable shielding is available, it can be wired single-sided to the terminal marked “S”. • Impulse devices with optocouplers or electrically isolated transistor outputs must be connected to “P-“ and “P+” with the correct polarity. • Impulse devices with S0 interface according to DIN 43864 are connected to the “S0+” and “S0-“ terminals with consideration of the correct polarity. An additional power supply of 12VDC to 27VDC sourcing minimum 30mA current must be wired to the terminals “U+” and “U-“. Note: You can use only one of the two pulse inputs of PadPuls M1C.

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 M1C 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 M1C User Manual 26.09.01, Version 1.3 5 GmbH, Stettiner Str. 38, D-33106 Paderborn 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 which are available on the market! The selected baudrate must be 6 26.09.01, Version 1.3 PadPuls M1C User Manual GmbH, Stettiner Str. 38, D-33106 Paderborn identical to the baudrate of the M-Bus device. (see: “New M-Bus Baudrate”). The PadPuls M1C 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 device switches to the new baudrate. This button is not needed for the PadPuls M1C, 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. In case of PadPuls M1C 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 MBus device. The item is read only. Type shows the type (here: PadPuls 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). PadPuls M1C User Manual 26.09.01, Version 1.3 7 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. 8 26.09.01, Version 1.3 PadPuls M1C User Manual GmbH, Stettiner Str. 38, D-33106 Paderborn 3.3 Sheet PadPuls M1 These sheet shows the actual settings and values of the PadPuls M1C. 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 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 adapter. Fabric. no. is insignificant for PadPuls M1C. Medium describes the measured medium of the connected meter. Examples: Oil, Water, Heat, Electricity PadPuls M1C User Manual 26.09.01, Version 1.3 9 GmbH, Stettiner Str. 38, D-33106 Paderborn Multiplicator 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 1434-3 are offered in the selection list. Counter is the accumulated counter. It has to be related to the unit mentioned 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 removed after opening the sealable front cover of the housing and pressing the “Unprotect” pushbutton. Permanent error is insignificant for the PadPuls M1C. Write protect Transmits a command to the PadPuls M1C 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 M1C changes the options only if the write protect is deactivated. It is recommended to read the data after writing and check it. 10 26.09.01, Version 1.3 PadPuls M1C User Manual GmbH, Stettiner Str. 38, D-33106 Paderborn Notes: 1.
