1 Operating Instructions Win Scale YSW03 Verifiable PC driver program with verifiable display and alibi memory for scales and weighing platforms

2 Intended use M Note: With regard to operation and user programming, special attention must be paid to the sections marked with the M symbol. The Sartorius Win Scale application is a type-approved driver program for a verifiable display and alibi memory used to store values measured by one or several balances, scales or weighing platforms (weighing modules). Communication between a PC and the balance, scale or weighing platform takes place over a serial RS-232/RS-485 data interface. The devices must be suitable, set up and certified for the transmission protocol xbpi (extended Balance Processor Interface) or SBI (Sartorius Balance Interface), which are used for communication. In the configuration of xbpi for some model series, it is possible to show the verified display and operating settings on the screen of the PC. No additional operating terminal for the weighing platform is then required. In the configuration of SBI for other model series, the program is suitable for secure storage of the verified display values on the PC (alibi memory). The display and operating settings of the scale then continue to be used. It is therefore possible, for example, to connect scales of the FB, FC, FD, LA and LP series, isi-industrial terminals and IS weighing platforms. If you use Sartorius Win Scale in conjunction with an IS weighing platform, an isi industrial display and operator terminal is not necessary. Several devices (up to 31) can be connected via a special network ( xbus network ) in which each device is identifiable by a unique address. The Sartorius Win Scale application is used: to emulate a verifiable display and operator terminal (a verifiable window ) on the PC. The verifiable window is placed on the screen in a location selected freely by the user and cannot be overwritten there by any other application. for verifiable storage of data (in the alibi memory; please see the section entitled Alibi Memory above on the right). as an interface between the user, other software processes running in parallel (DDE clients: Dynamic Data Exchange) and the scale or weighing platform. Example: Data exchange between the scale or IS weighting platform and the PC takes place over a special, verifiable communication library that is adapted to the external device. Data from the device is stored in alibi memory, which provides reliable protection against manipulation. The alibi memory enables the user to retrieve and further process verifiable data directly from the balance, scale or weighing platform using his own software. Furthermore, the user can take advantage of the range of commands available to him to initiate various functions on the balance, scale or IS platform (e.g. taring/ zeroing the display, starting calibration/ adjustment, accessing or changing the balance or scale operating menu). On verifiable devices, the range of commands is limited accordingly. Alibi memory The determination of the mass of an object for trade purposes is subject to calibration and verification requirements. If, for example, an invoice indicating the mass of an object is generated via a connected electronic data processing device (the number of intermediate stations does not matter here), calibration and verification regulations apply all the way to the printout of that invoice or any other record. The connected electronic data processing device can be a PC or computer network, for which it would be unrealistic to demand type approval certificates or verification. However, in order to comply with the requirements of this legally regulated area, the concept of alibi memory was created. This is a type-approved, protected memory. Data to be further processed in transactions subject to calibration requirements is stored in this memory, where it cannot be manipulated. The data can be reaccessed on command at any time. When the data is processed, it is only necessary to indicate an ID that subsequently allows for unique retrieval of the stored data. It is the responsibility of the operator to ensure that this takes place. The archiving duration of the data is regulated at the national level. Compliance with the established periods is also the responsibility of the operator. Since this may become problematic for large amounts of data and long storage times, the Sartorius memory concept permits the stored data to be securely exported and reimported as required.

In both cases, calibration by a duly authorized representative of Sartorius AG or calibration authorities is required. Subsequent installation of Sartorius Win Scale for use in conjunction with a balance or scale that has already been calibrated requires recalibration by the calibration authorities. The section entitled Information in the Display in the Operation section describes the inspection of the display required during calibration to ensure that the data is presented correctly. In addition, the mandatory inspection of correct storage of the weight values subject to calibration in the alibi memory is explained under Function Test of the Alibi Memory in the section entitled Accessing the Service Menu in the Operation section. The mandatory comparison of the software ID with a target value is described under Reading Program Information in the section entitled Accessing the Service Menu in the Operation section. When using the Sartorius Win Scale application, it is imperative that you follow the rules listed below: The display window of Sartorius Win Scale may not be imitated. This means that no similar display window can be generated, since this could lead to confusion with the display window of Sartorius Win Scale. The display window of Sartorius Win Scale in XBPi mode may not be hidden. The application has been designed so that the display window reappears in the foreground of the screen at least after any change in the readout from a connected weighing instrument. It is therefore up to the operator to ensure that no attempts are made to place the display window in the background, to hide parts of the window or to falsify the window with outside information. - In SBI mode, no verifiable readout may be shown in the display window; for this reason, hiding of the window is permitted. In addition to inspection of the findings with regard to the information displayed on the monitor (when using as a verifiable display), a function test is sufficient for the verifiable memory. - The following function test of the verifiable memory is sufficient: Performance of 5 weighings with saving of the data in each case (e.g. press the printout button on the scale). The weighing results should be recorded for subsequent checking. Inspection of the stored weighing results for agreement with the previously recorded values: Click on S in monitor display to access the service menu. In the Password dialog, enter the user or system password and confirm with OK. In the Service Menu dialog, select Verifiable Memory and confirm with OK. In the Display Under Day File dialog, select the desired day and under Search enter the desired number under Verifiable ID, if necessary. The user must check the integrity of the legal metrology software modules every day. This is accomplished by accessing the software information (for this purpose, please refer to the sections entitled Accessing the Service Menu and Reading Program Information in the Operation section). A weight value may only be used and/or further processed in a verified context if it has been stored in the alibi memory. The storage time for legal metrology data depends on the application. It is the responsibility of the operator to ensure compliance. The operator is responsible for providing storage space for the alibi memory on the local hard drive. Configuration of the ring storage of the alibi memory must be performed by the operator (see here the section Operation Configuring the Alibi Memory ). This also applies to measures for backing up the data. The alibi memory is protected against manipulation by checksums. Nevertheless, the operator may not attempt to bypass this protection by analyzing or manipulating the files. The computer used must conform to EEC Council Directive 89/336/EEC and must bear the CE symbol. All connected peripheral devices subject to calibration requirements (keyboard, monitor, etc) must also bear this certification. The PC platform must fulfill the minimum requirements specified under System Requirements in the Installation section.

4 System Overview M Software System The figure below shows the individual components of Sartorius Win Scale as a server in conjunction with a balance, scale or weighing platform and an external software application (client). Externally connected devices (balances, scales or weighing platforms) communicate with the help of modularly designed, device-specific drivers known as verifiable communication libraries. Each library contains a defined range of functions (SARTOCOM protocol) as a software interface to a non-verifiable application and specific commands for communication with the external device. When the application is running, an appropriate verifiable communication library is loaded for the particular external device with which the program is to communicate. All program-specific settings are stored in a configuration file. When the application is closed, a copy is made of this configuration file. If the original configuration file is destroyed, a valid configuration file can be restored from this copy. xbus Network All devices equipped with a serial RS-485 data interface and set to the xbpi communication mode can be linked together in an xbus network (see the figure on the left). In this special Sartorius network, up to 31 devices (balances, scales or IS weighing platforms) can be connected together. On scales or balances (such as the FB/FC or LA/LP series), the standard RS- 232 data interface must be replaced with an RS-485 interface. This is available as an accessory for devices of the FB/FC series (YDO01F and YDO02F for scales and balances with high loads 12 kg) and for the LA/LP series upon request in the Fast Factory department. To connect an xbus network or an individual device equipped with an RS-485 data interface (e.g. an IS weighing platform) to a PC equipped with a standard RS-232 interface, use one of the two options described below: Installation of an RS-485 interface card in the PC. For this purpose, Sartorius offers the W&T PC card (order no.: 62PC-Y014). This is a dual interface that can be installed in any commercially available PC with a standard AT bus. A detailed description is included with the card. Use of the interface converter (see figure on page 5). The RS-232 data interface on the converter is connected to the RS-232 interface on the PC via cable (25-pin D-Sub female connector at both ends). The wiring diagram of the RS-485 interface on the converter and all other details are included in the accompanying operating instructions. Because of the individual cable lengths used for data transmission according to the RS-485 standard, there is no standard cable for this purpose. If you operate IS weighing platforms in the xbus network, they must have their own power supply. If necessary, the IS weighing platform must be converted (exception: IS weighing platforms that are controlled by an isi industrial terminal and scales of the FD series). For information on connecting IS weighing platforms, consult the section Connecting an IS Weighing Platform to the PC under Connecting Devices to the PC. To ensure unique identification in the network, each component must have a unique bus address that is stored in the device. The addresses may have the values 1 to 31. The data exchange within the network takes place in binary. Cyclical data output from a device is not possible in bus operation mode. A detailed description of the xbus can be found in the Protocol and Function Description of the xbpi Interface of the isi Operating Terminals. In addition to the EC type approval of the balance or scale, the associated test certificate with appendix must be presented for calibration. It must be determined whether the verifiable program is operating properly. The actual value of the software ID is calculated and displayed by loading the menu item Information, Software in the service menu. The saved set value (CB for software version / 8228A94E for software version ) is also displayed. If both values match, the software has been loaded properly and the computer may be used for purposes subject to calibration requirements.

5 SBI If weighing platforms are equipped with an RS-232 data interface, they can be addressed within the SBI protocol. In SBI mode, data can be received from up to three connected devices. Note: In legal metrology, only the connection of a single balance or scale is permitted in SBI mode! No multi-range scales or multi-division scales may be connected when using the SBI protocol. In addition to the EC type approval of the balance or scale, the associated test certificate with appendix must be presented for calibration. It must be determined whether the verifiable program is operating properly. The actual value of the software ID is calculated and displayed by loading the menu item Information, Software in the service menu. The saved set value (8228A94E version for SBI) is also displayed. If both values match, the software has been loaded properly and the computer may be used for purposes subject to calibration requirements. If the recorded data should be stored in the alibi memory, the configuration data must first be entered based on the information on the test certificate: in case of calibration, the calibration value e must be entered. Combined tare/null or blockprint setting, indication of d for scales d not equal to e. For balances and scales with combined taring and zeroing function, Combined tare/null must be selected, for balances and scales with separate taring and zeroing functions, Blockprint must be selected. Serial number, decimal places, etc. are entered in the configuration dialog windows since this data is not automatically collected (as in XBPI mode).

14 Connecting Devices to the PC Connecting the FB/FC series to the PC Scales of the FB/FC series are equipped with a built-in RS-232 data interface. The data output port (12-pin, round socket) is connected to the PC via cable YCC01-03ISM5. If the PC has a 9- pin connector rather than a 25-pin connector, you must also connect a adapter cable between the PC and the interface cable. Set the balance to operate in the xbpi communication mode. For more information, refer to the installation and operating instructions for the particular balance. Connecting the LA/LP series to the PC Scales of the LA/LP series are equipped with a built-in RS-232 data interface. The data output port (25-pin D-Sub female) is connected to the PC via cable If the PC has a 9-pin connector rather than a 25-pin connector, you must also connect a adapter cable between the PC and the interface cable. Set the balance to operate in the xbpi communication mode. For more information, refer to the installation and operating instructions for the particular balance. Connecting an isi Operating Terminal/FD Series to the PC The isi industrial terminal must be equipped with a serial RS-232 interface. Scales of the FD Series come standard with an RS-232 interface. The data output port (12-pin, round socket) is connected to the PC via cable YCC01-03ISM5. If the PC has a 9-pin connector rather than a 25-pin connector, you must also connect a adapter cable between the PC and the interface cable. Set the RS-232 interface ( COM interface) to operate in the XBPI-232 communication mode by accessing the system settings. For more information, refer to the installation and operating instructions for the isi industrial terminal or the FD series scale. Connecting an IS Weighing Platform to the PC IS weighing platforms are equipped at the factory with an RS-485 interface and, in general, do not have their own power supply. The weighing platforms are operated in conjunction with an isi industrial terminal, and power is supplied via the connecting cable. To directly connect a weighing platform (or several weighing platforms in an xbus network see the section entitled xbus Network for more information) to the PC, the weighing platform must be retrofitted with its own power supply. For this purpose, you will need an installation kit for an external power supply (for line voltage or mains supply of 220V: order no ) and a YAS03IS upgrade kit. To facilitate data exchange between the PC and the weighing platform, you must do one of the following: Use an RS-232/RS-485 interface converter, model , which is connected to the PC via cable The pin assignment for connecting a weighing platform is included in the installation and operating instructions for the interface converter. Install an RS-485 interface card in the PC. For example, the W&T PC card (order no. 62PC-Y014) is suitable for this purpose. Additional information on this can be found in the section xbus Network in the System Overview section.

15 Operation M Loading Sartorius Win Scale Requirements: M The connection between the device and the PC must be properly established (see also Connecting a Device to the PC ). The application must be installed (see also Installing Sartorius Win Scale ). Double-click on the Win Scale icon on the PC desktop. > This starts the application. An integrity test of the program file (.exe file ) is performed first. If this fails, a corresponding error message appears. The application is closed immediately. This implies that the program file has been manipulated. In this case, notify your Sartorius dealer, your nearest Sartorius Service Center or the International Technical Support Unit based in Goettingen, Germany, since you will not be able to run the program and it is, therefore, unusable. If one of the error messages shown on the left is displayed when you start the application, Sartorius Win Scale will also close immediately. In these cases, the application was not installed correctly or the file shown in the error message could not be found. To correct this error: Reinstall the application (see the section entitled Installing Sartorius Win Scale for more information). If the error continues to occur, contact your Sartorius dealer, your nearest Sartorius Service Center or the International Technical Support Unit based in Goettingen, Germany. If the self-test of the application is completed successfully, the verifiable window will appear on screen as the virtual display and operator terminal. The first time Sartorius Win Scale is run after reinstallation, the verifiable window is positioned in the upper left-hand corner of the screen. Otherwise, the window remains in the position defined by the user the last time the application was accessed (see also the section entitled Configuring the Display Position ). The virtual display and operator terminal of the Sartorius Win Scale application is shown in a fixed area on the screen where it cannot be overwritten. It cannot be hidden by any other application, and it returns to the foreground of the display after each change to a measured value. The figure on the left shows a practical example of the Sartorius Win Scale virtual display and operator terminal, which cannot be overwritten, together with another application (e.g. MS Excel).

16 If the application starts correctly but the communication library necessary for communication with the connected weighing instrument is missing, the error message ERR APP 13 is displayed.

To exit the screen: Click on the OK button.

22 Defining the Communication Library Purpose: Selecting the verifiable communication library necessary for communication with the connected weighing instrument (or instruments). In order to work with Sartorius Win Scale, at least one verifiable communication library must exist. This library functions as a driver for the connected weighing instrument and must, therefore, correspond to the device with which communication is to be established. The communication library (e.g. srvind3301.dll ) is a separate file, not an integral component of the Sartorius Win Scale software module (see also Software System in the System Overview section), but it is included in the delivery. The supplied file enables communication with the most important Sartorius instruments via the xbpi protocol; please consult with your Sartorius dealer, the Sartorius Service Center or the International Technical Support Unit based in Goettingen, Germany, for special applications. For licensing reasons, an access code for each communication library is delivered separately; this code functions as a key to enable use of the corresponding library. The following steps are necessary to define the communication library: Selection of a protocol ID Assignment of the verifiable communication library linked to this protocol ID (entry of the file name with directory path) Entry of the corresponding access code Updating of the library directory To access the service menu: Use the mouse to click on the S (14) button or enter S on the keyboard. > A selection screen appears for entering the user status and corresponding password. Select the System user status by clicking on it. Enter the system password and confirm by clicking on the OK button. > The service menu appears on screen. Click on the Communication library button in the Communication weighing platform section of the menu or enter [ALT] + L on the keyboard.

23 > The Communication Library Settings screen is displayed. Enter the desired protocol ID (e.g. srvind3301.dll ). The protocol ID is user-definable and enables the application to use the communication library linked to this name. Enter the file name of the communication library with the complete directory path. To do this, click on... button, select the required file in the Browse screen, (e.g. srvind3301.dll ) and confirm by clicking on the Open button. The file then appears in the Communication library window. Enter the access code. The access code is delivered separately with the product. Update the communication library: Click on the Update button or enter [ALT] + U on the keyboard. If a communication library already exists, you will be asked to confirm that you wish to update the library. > The selected communication library is displayed in the Current configuration box. If one or more libraries are already listed here, the new library will be placed at the top of the list. To exit the screen and confirm changes to the settings: Click on the OK button. To cancel without changing the settings: Click on the Cancel button. Changing the current communication library (if several communication libraries exist): Select the new communication library in the Current configuration box by clicking on it with the mouse. Update the communication library by clicking on the Update button. Answer the prompt with Yes. > The currently valid library (protocol ID, file name with directory path and access code) is redisplayed in the Assign name section. The list of available libraries in the Current Configuration box is reordered so that the current configuration is listed first.

24 Removing a Communication Library (If multiple communication libraries exist): Select the communication library to be removed in the Current Configuration box by clicking on it with the mouse. Click on the Remove button or enter [ALT] + R on the keyboard to remove the communication library. Answer the prompt with Yes. > The currently valid library (protocol ID, file name with directory path and access code) is redisplayed in the Assign name section. The deleted communication library is removed from the list of all existing communication libraries in the Current configuration box. If no communication libraries exist at this point, the error message ERR APP 01 will appear in the virtual display and operator terminal. For the program to function properly, a communication library must first be defined again. Configuring Communication with the Device Purpose: Setting all parameters necessary for communication with a weighing instrument, such as the device ID, communication protocol, device address, COM port on the PC and other interface parameters. Proper communication with the weighing instrument can be tested. To establish communication between the Sartorius Win Scale application and an external device, the following settings are required for the application and the external device: The Sartorius Win Scale application must use the verifiable communication library that corresponds to the external device. A name (protocol ID) that establishes the necessary connection is assigned to the library in the selection screen Communication Library Settings (see also the section Defining the Communication Library ). The device address, connection of the serial interface on the PC (COM port) and the interface parameters must be adapted for communication with the external device. The external device must be set to the transmission protocol configured in the Sartorius Win Scale application (see the section entitled Connecting Devices to the PC ). The external device must be correctly configured in order to select it for communication with Sartorius Win Scale via the button (22) in the virtual display and operator terminal. You can configure these settings in the Weighing Platform Settings screen, which is explained below.

25 To access the service menu: Use the mouse to click on the S (14) button or enter S on the keyboard. > A selection screen appears for entering the user status and corresponding password. Select the System user status by clicking on it. Enter the system password and confirm by clicking on the OK button. > The service menu appears on screen. Click on the Weighing platform button in the Communication weighing platform section of the menu or enter [ALT] + W on the keyboard. > The Weighing Platform Settings screen is displayed (see figure on the next page). Enter the device ID in the ID field. The device ID is user-definable. Once you have selected a device by clicking on the button (22) in the virtual display and operator terminal, this name appears in the field above the on-screen button (marked as (19) in the figure in the section entitled Information in the Display ). Note: Each new entry in the ID name field opens a new set of parameters (= communication path). Several sets of parameters can exist for the same device. However, this makes little sense in actual use because all parameters (communication protocol and all interface parameters) must be identical for the same device. Select the communication protocol for data transfer between the PC and the device in the Protocol field. Clicking on the button opens a selection window in which you can click on the desired protocol. This protocol name establishes the link to the verifiable communication library that supports communication with the external device (see the section entitled Defining the Communication Library ). Enter the device address in the Address field. The device address is a number between 1 and 31 (for an individual device, the address 0 is also acceptable) that is assigned only to that device. With the help of configuration programs, such as YAD01IS, a particular address can be assigned to a device. If you leave the Address field blank, the address will be interpreted as 0. Enter the number of the serial interface on the PC (COM port) used for data exchange between the PC and the device in the COM Port field. If, for example, the device is connected to the COM1 interface, enter 1 in the COM Port field. Entry of other interface parameters, such as baud rate, parity, handshake, data bits, and stop bits is optional. If these fields are left blank, ka (no entry) appears in each field. If data is entered into these fields, however, it must agree with the configuration of the device interface. Otherwise, data cannot be transmitted properly between the PC and the external device. To transfer the new communication parameters to the PC: Click on the Update button with the mouse or enter [ALT] + U on the keyboard. If you have changed an existing configuration (the entry in the ID name field was not changed), you must answer a prompt to confirm the updates. > The new set of parameters appears in the Current configuration list. This list is arranged alphabetically according to the entries in the ID name field. To exit the screen and confirm changes to the settings: Click on the OK button. To cancel without changing the settings: Click on the Cancel button.

26 Changing a communication parameter set (if multiple parameter sets exist): Select the set of parameters to be changed in the Current configuration box by clicking on it. The communication parameters that have been valid up to now are displayed in the corresponding fields and can be changed. If you change the data in the ID name field in the process, this will be interpreted by the program as a new set of parameters (see the note on the previous page). Update the parameter set by clicking on the Update button. Answer the prompt with Yes. > The changed parameter set is displayed again in the Current configuration list. Removing a set of communication parameters (if several sets of parameters exist): Select the set of parameters to be removed in the Current configuration box by clicking on it. Click on the Remove button or enter [ALT] + R on the keyboard to remove the parameter set. Answer the prompt with Yes. > The deleted set of parameters is removed from the list of all existing sets of communication parameters under Current configuration. If no sets of parameters exist at this point, the error message ERR APP 01 will appear in the virtual display and operator terminal. This error message disappears as soon as proper communication to an external device is re-established. Testing the connection to a device: Select the connection to be tested by clicking on it in the Current configuration box. > The corresponding communication parameters are displayed in the applicable fields. Click on the Test button or enter [ALT] + T on the keyboard. > The Weighing Platform Information screen is displayed. If a connection to a particular device has been established, the applicable identifying data for that device, such as the model name, serial number and metrological data, appear on this screen. If the connection could not be established (e.g. due to faulty communication parameter settings),??? appears in the Model and Serial Number fields. To exit the screen: Click on the OK button. Defining DDE Connection Parameters Purpose: Selecting the communication parameters necessary for Dynamic Data Exchange (DDE) between a DDE server program and a DDE client program (see section Communication with External Programs (DDE Clients) ). As a DDE server program, the Sartorius Win Scale application can receive and execute queries and requests from an external program (DDE client program) (e.g. requests to read a net value at stability and provide this data to the client program or to tare the weighing instrument). The DDE server program makes information available for retrieval without actively seeking communication with other software processes. DDE client programs can establish DDE communication with a server application using the DDE communication parameters made available by the server. These parameters are defined by the three terms Service, Topic and Item : The Service parameter is the name that the server program recognizes when a DDE client program attempts to establish a DDE connection. The Topic parameter describes the type of data source. The Item parameter identifies the actual data requested by the DDE client. The entries for the DDE communication parameters are userdefinable in the DDE server. This section describes only the entry of connection parameters. For further information on the DDE interface and application examples, refer to the section entitled Communication with External Programs (DDE Clients). To access the service menu: Use the mouse to click on the S (14) button or enter S on the keyboard. > A selection screen appears for entering the user status and corresponding password. Select the System user status by clicking on it. Enter the system password and confirm by clicking on the OK button. > The service menu appears on screen. Click on the Connection parameters button in the Communication DDE section or enter [ALT] + B on the keyboard.

27 > The Connection Parameters Settings screen is displayed. Enter the Service, Topic and Item parameters in the respective fields. These must also be defined in the client application to be served by Sartorius Win Scale. To confirm the settings: Click on the OK button. If you do not want to save the settings: Click on the Cancel button. Configuring the Alibi Memory M Purpose: Defining a directory path and storage period for data in the alibi memory. Data stored in the alibi memory is protected against manipulation by a security mechanism (CRC: Cyclic Redundancy Check). The security mechanism is designed to satisfy the special statutory requirements that apply to the archiving of verifiable data. Data stored in this memory is considered verifiable for the entire period for which it is stored in the memory. The first time you run Sartorius Win Scale after installing the program, you must define a directory path under which files will be stored and protected in the alibi memory. The directory ( ESP is generally selected as the name for the alibi memory) must be created on the local hard disk of the PC being used. It may not be located on a diskette or a network drive. Each time data is stored in the alibi memory, the program checks whether sufficient storage capacity exists under the defined directory path. As a ring buffer, the alibi memory is set up with a defined storage capacity allocated in days. Once the defined time period expires, the oldest day file is moved from the alibi memory to the archive directory WINSCALE-ESP-DEL- FILES ( archived day files ). The files moved in this way are protected against manipulation with checksums in the same manner as the files in the ring buffer. If an attempt is made to alter a file stored in the alibi memory or in the archive directory, the file is identified by the program as a manipulated file and removed from the alibi memory or archive directory. These files are stored in the directory WINSCALE-ESP-CRC-ERROR. To access the service menu: Use the mouse to click on the S (14) button or enter S on the keyboard. > A selection screen appears for entering the user status and corresponding password. Select the System user status by clicking on it. Enter the system password and confirm by clicking on the OK button. > The service menu appears on screen. Click on the Settings button in the Verifiable Memory (alibi memory) section of the menu or enter [ALT] + E on the keyboard.

28 > The Settings screen is displayed. Enter the time period for data to be stored in the ring buffer (1 to 30,000 days) in the Time frame field. The time period is dependent on the legal requirements of your country. Enter the path for the Verifiable Memory directory in the Memory path field. The default setting for the path is C:\ESP. Note: The alibi memory (ring buffer) must be located on the local hard disk. If this is not the case, a corresponding error message will be displayed, and you will be given the option of correcting the error (see the figure below on the left). If you do not make a correction, the default C:\ESP will be used as the path. Note: The paths for archived data ( WINSCALE-ESP-DEL-FILES ) and altered data ( WINSCALE-ESP-CRC-ERROR ) are created as subdirectories of the alibi memory (ESP). To save the configuration: Click on the OK button or enter [ALT] + O on the keyboard. To cancel the configuration: Click on the Cancel button or enter [ALT] + C on the keyboard. Function Test of the Alibi Memory M Purpose: Testing the alibi memory to ensure error-free function. Immediately after it has been configured, the alibi memory must be tested to ensure error-free function and compliance with the applicable legal requirements. This is done by performing several weighing operations, storing the resulting data in the alibi memory, accessing the stored data and checking to ensure that it was stored correctly (for more information, see also the sections entitled Writing the Weight to Alibi Memory and Reading the Alibi Memory and Exporting Data ). Perform a weighing operation and store the weight in the alibi memory. To do this, click on the E button (15) with the mouse or enter E on the keyboard (see Writing the Weight to the Alibi Memory ). Repeat the procedure several times with various weights. To access the service menu and read the data in the Alibi memory (see also Accessing the Service Menu Reading the Alibi Memory and Exporting Data ): Click on the S button (14) with the mouse or enter S on the keyboard. > A selection screen appears for entering the user status and corresponding password. Click on User to select this status. You can also select the System user status instead, which carries higher privileges. Enter the password for the particular user status selected, and click on the OK button to confirm.

29 > The service menu appears on screen. Select the alibi memory by clicking on the Verifiable memory button in the Verifiable memory section of the menu or by entering [ALT] + V on the keyboard. > The Display screen appears. To select a date: Clicking on the button opens a selection window in which you can click on the desired date. Note: If you do not first choose a date when selecting a data record, you will be alerted by a corresponding error message. Select the desired data record by clicking on it with the mouse in the Data record box. As an alternative method, enter the verifiable ID for this data record. The ID appears in every data record as the first group of numbers before the date. > The selected data record, which appears in compressed format in the Data record box, is shown in detail in the Contents section of the window. Check the displayed data record to determine if it has a verifiable ID and a checksum. These must be displayed in their respectively designated fields. The checksum must be labeled with OK:. The actual checksum can be seen at the bottom of the data record display after the remarks, and the whole checksum can be viewed by sliding the scroll bar to the right side of the window (see figure).

30 Check the data records of all test weighing operations in the same manner. All data records must have a unique verifiable ID and a correct checksum. If errors occur, notify your Sartorius dealer, the nearest Sartorius Service Center or the International Technical Support Unit based in Goettingen, Germany. In this case, the Sartorius Win Scale application may not be used in legal metrology. Reading the Alibi Memory and Exporting Data Purpose: Reading out data stored in the 3 memories for weights. The data records can be selected and exported for further processing. In the process, a copy of the current day file is created in ASCII format. The Sartorius Win Scale application features 3 storage areas for saving weights. They provide a graduated hierarchy of protection to safeguard the integrity of the data (see also the section entitled Configuring the Alibi Memory ): Verifiable Memory directory: Ring buffer with defined capacity (1 to 30,000 days) Archived Day Files directory: Contains all data records that were moved out of the Verifiable Memory directory due to their age in relation to the current date Altered Day Files directory: Contains all files that were originally in either the Verifiable Memory directory or the Archived Day Files directory but were moved out of these directories because the content of the files was changed (e.g. the files were edited). You can view data stored in these directories by selecting the respective memory area in the service menu. For further processing by other applications, such as EXCEL, they must first be exported. In the process, the data is presented in ASCII format and can therefore be edited. To access the service menu: Use the mouse to click on the S (14) button or enter S on the keyboard. > A selection screen appears for entering the user status and corresponding password. Click on User to select this status. You can also select the System user status instead, which carries higher privileges. Enter the password for the particular user status selected, and click on the OK button to confirm. > The service menu appears on screen. Select the desired memory by clicking on the respective button in the Verifiable memory section of the menu: Ring buffer (alibi memory): Click on the Verifiable memory button or enter [ALT] + I on the keyboard. Archived day files: Click on the Archived Day Files button or enter [ALT] + A on the keyboard. Altered day files: Click on the Altered Day Files button or enter [ALT] + T on the keyboard.

31 > The Display screen appears. To select a date: Clicking on the button opens a selection window in which you can click on the desired date. Note: If you do not first choose a date when selecting a data record, you will be alerted by a corresponding error message (see figure on the left below). > In the Data record box, all data records for the date selected are listed. Note: Only data records that were generated within the storage period are located in the Verifiable Memory directory. All other data records are located in the archive directory. This directory can be reached from the service menu by clicking on the Archived Day Files button. All data records that have been changed are stored in the Altered Day Files directory, regardless of the date they were created. This directory can be reached from the service menu by clicking on the Altered Day Files button. Therefore, if you cannot find a certain data record in a particular memory, or if this memory is empty, you should search the other two memories as well. Select the desired data record by clicking on it with the mouse in the Data record box. As an alternative method, enter the verifiable ID for this data record. The ID appears in every data record as the first group of numbers before the date. > The selected data record, which appears in compressed format in the Data record box, is shown in detail in the Contents section of the window. Exporting data for further processing: Click on the Export button or enter [ALT] + E on the keyboard. > The Export screen is displayed. Select the storage medium (hard disk, diskette,...), target directory and file name. The name of the data record with the file extension asc is suggested as the file name, since the exported file is in ASCII format. Next, click on the Save button to save the data record under the specified path. The program then returns to the Display screen. To cancel data export: Click on the Cancel button, and the program returns to the Display screen. To exit the screen: Click on the OK button or enter [ALT] + O on the keyboard. The program returns to the Service menu screen.

32 Configuring the Display Position Purpose: Positioning the virtual display and operator terminal on the screen.

34 Communication with External Programs (DDE Clients) DDE Interface The Sartorius Win Scale application can be used as an interface between a user, one or more software processes running in parallel and one or more devices used to exchange data with the software process or processes. This type of data exchange is referred to as Dynamic Data Exchange (DDE). In this case, Sartorius Win Scale functions as a DDE server, and the individual user process is referred to as the DDE client. The Sartorius Win Scale DDE server makes information available for retrieval without actively seeking communication with the user (DDE client) processes. DDE client programs can establish the DDE connection to the server application program using the DDE communication parameters made available by the server. These communication parameters are usually defined as Service, Topic and Item. The Service parameter contains an ID that the server recognizes when a DDE client attempts to establish DDE communication. The Topic parameter describes the type of data source. The Item parameter contains a variable identifying the actual data requested by the DDE client. DDE communication parameters in the Sartorius Win Scale DDE server are user-definable (see the section entitled Defining DDE Connection Parameters in the Operation section). The following default settings are valid at the start of the application: Service: = WinScale Topic: = AktWaage Item: = AktDaten read out automatically and, therefore, the DDE client s request to be answered by the DDE server. An alternative solution would be the explicit reading out of the Item variable with the DDE command Request. Creating the Data Request to the DDE Server (Request String) The request string consists of the key word sarto_cmd(...). The ID for the command to be executed is placed in the parentheses. If the command contains multiple parameters, these are separated by semicolons (e.g. sarto_cmd(p1;p2;p3) with the parameters P1, P2, P3). Example: Request for the current net weight with a stability check. The weight should be stored in the verifiable memory with the label Test_weighing. Required request string: sarto_cmd(w;esp;test_weighing) (see also the table DDE Functions ) The parameters of the command have the following meanings: Parameter 1: Command ID: W Request weight Parameter 2: Command ID: ESP Transfer weight to alibi memory Parameter 3: Transfer variable: Test_weighing Transferred weight labeled in the alibi memory with the comment Test_weighing Data Exchange The user program (DDE client) and the Sartorius Win Scale DDE server communicate by exchanging strings. First the DDE client sends a request string to the DDE server. The server then extracts the command parameter(s) from this string, executes the command and creates a response string for the DDE client. The request string is case-insensitive, so upper-case and lower-case letters have no bearing on the correct interpretation of the command. The following application example illustrates the fundamental concept of data exchange between the user program and the DDE server. The details of the DDE implementation depend on the development environment used to create the implementation. Task: The DDE client requests the current weight. The data exchange between the DDE client and the DDE server includes the following steps: The connection is established by the DDE client in accordance with the DDE communication parameters initialized in the DDE server (e.g.: Service = WinScale, Topic = AktWaage, Item = AktDaten). The DDE client requests the current weight with the DDE command Execute. For this purpose, the string sarto_cmd(w) is sent to the DDE server (see also the section entitled DDE Functions ). The Sartorius Win Scale DDE server decodes the DDE client request, from which it creates an internal command according to the internal SARTOCOM command set. The standardized SARTOCOM software interface can communicate with the individual device-specific communication libraries. The command is executed, and the current weight is sent back to the application. The application places this response in the Item variable via the DDE software interface so it can be read by the DDE client. Depending on how the DDE communication has been implemented in the DDE client, a change to the Item variable triggers an event, for example, that causes the variable to be Implementation Principles for User Software The software described in the following sections (application examples 1 and 2) was developed using the development system Microsoft Visual Basic. Menu structures and screen layouts were designed according to the standards of Microsoft Windows 95 and Windows NT and were primarily designed in the interests of user-friendliness. Windows 95, Windows 98, Windows 2000, Windows NT, Windows XP, MS Office, MS Excel and MS Word are registered trademarks of Microsoft Inc.

35 DDE Application Example 1 In the application example illustrated here, the following functions can be carried out: Establishment of the connection to Sartorius Win Scale Requesting of the net weight without stability check with device status information Note: The following source code is provided as an example for the fundamental structure of a DDE application. Sartorius assumes no liability for the error-free performance of the program. Form: Button: Button: Label: HerstellenVerbBtn AnfordernWertBtn Anzeige Source code: Private Sub HerstellenVerBtn_Click() Cancel DDE link Anzeige.LinkMode = 0 Set DDE connection parameters Anzeige.LinkTopic = WinScale AktWaage Establish DDE link Anzeige.LinkMode = 1 End Sub Private Sub AnfordernWertBtn_Click() Set DDE timeout Anzeige.LinkTimeout = Request and display weight data Anzeige.LinkExecute sarto_cmd(ws) End Sub After you run the program, a window with two on-screen buttons and a status line is displayed (see figure above on the left). Clicking on the Establish Link to Win Scale button creates a communication path from the DDE client to the Sartorius Win Scale DDE server. The DDE server is now ready to receive commands from the DDE client. The text in the status line changes from No link to Sartorius Win Scale - OK. If you click on the Request weight button, the command Request current net weight without stability check with device status information is sent to the DDE server. As soon as this data has been made available by the server, the DDE client retrieves it and displays it in the status line.
