The Genesis software is used to format customised labels, create PLUs and collect management information.

8.3 Having a data storage system (Herbert Datasafe) incorporated into a computer (PC) connected directly to the indicator via the fibre optic protective interface or connected to the indicator via a Herbert CC430 tallyroll printer. A full description of the data storage system follows.

8.3.1 Description

The Herbert DataSafe scale driver software package is installed in the computer. This receives weight data from the weight indicator or optionally from the Herbert CC430 tallyroll printer, and transmits it to the main software on the computer. It also records all valid weights with their unique consecutive numbers in a computer file. The DataSafe scale driver incorporates a number of security features to ensure that the recorded data remains intact, and that any attempt to tamper with it will be detected.

A DataSafe viewer is also added to the computer. This can be used to inspect the recorded weights and consecutive numbers at any time. It detects and highlights any recorded weights which have been modified or otherwise tampered with.

The DataSafe scale driver and viewer may be used in two configurations:

(a) With the CC430 tallyroll printer (Figure 2). This configuration is normally used as a transitional stage during the removal of the CC430. In this case the unique consecutive number is generated by the CC430.

(b) Without the CC430 (Figure 3). This is normally the long-term configuration. In this case the unique consecutive number is generated by the scale driver.

The DataSafe scale driver and viewer are authorised for use on any computer running the Unix operating system.

8.3.2 Operating requirements and conditions

8.3.2.1 DataSafe scale driver

The DataSafe scale driver receives weight requests from the main software. It passes these on to the weighing system, which may be an indicator alone (configuration (b)) or an indicator with a CC430 (configuration (a)) When a stable weight is available, the weighing instrument returns the weight to the scale driver with an error flag. If the weight is not valid, the error flag is set, and an error code is returned indicating the error type. If the weight is valid the scale driver adds a unique consecutive number and the date and time to the weight and records it in the current datalog file for this weighing instrument. It also returns the weight data, the consecutive number and the time and date to the main software. If there is an error the scale driver does not generate a consecutive number, and it returns the error description to the main software.

If the weighing system includes a CC430 (configuration (a)) the CC430 generates the consecutive number for each valid weight and returns it to the scale driver with the weight. In this case the scale driver does not generate its own consecutive number, but records that returned by the CC430 in the current datalog file for this scale.

Each weighing instrument has its own sequence of unique consecutive numbers. These numbers shall not be repeated within 6 months. The consecutive number shall not be capable of readily being reset, other than by use of a pass-word which shall be kept confidential to Herbert & Sons, and which changes at the end of every day.

6

Data log files are held in a “/dti” directory on the computer’s hard disk, separate from files belonging to the main software. In order to avoid the generation of excessively large files, the scale driver periodically creates a new datalog file. Each file contains a header giving the number and description of the scale to which it belongs. The scale driver keeps the data for each weighing instrument for at least 6 months. To avoid the accumulation of unnecessary data, the old datalog files are eventually overwritten.

The datalog file is organised as a header followed by a separate record for each weight. The data stored in each record consists of:

(a) Unique consecutive number (b) Date (c) Time (d) Net weight (e) Tare (if available) (f) A flag indicating whether gross, semi-auto tare or preset tare weighing is in use (g) Unit of measure

The data is stored in an encoded form, and cannot readily be altered using an editor.

Additionally with each record is stored a check-code. The scale driver calculates the check code dependent on all the data in the record, using a non-obvious encoding method. If the data in the record were to be changed by any means, it shall not be readily possible to calculate the corresponding check code. This technique allows the DataSafe viewer to detect and highlight any records which have been altered.

After writing the data to the datalog file, the scale driver reads it back and checks it against the original data. Only if the data has been verified to be correct does the scale driver return the weight data to the main software. If for any reason the data has not been correctly stored in the datalog file, an error message is returned. This ensures that if any problem occurs to prevent the correct logging of the data, operation of the system will stop rather than continue without logging.

Both the DataSafe scale driver and the viewer contain Cyclic Redundancy Check (CRC) codes, based on the whole contents of the program. If the program is altered by any means, the CRC code will change. The CRC code for the authorised versions of these programs are on file at the NWML. Both programs can be run in a special mode to calculate and display their own CRC codes. The user can compare the displayed code with the code filed at NWML to check that the authorised version is being run. In addition, both programs will check their own CRC codes frequently, and will abort if the check fails. This ensures that if the program is altered in any unauthorised way, it cannot be used.

8.3.2.2 DataSafe viewer

The DataSafe viewer provides facilities for inspecting the data recorded in the datalog files. When first run, the viewer asks the user to select a weighing instrument from a list present (if there is only one weighing instrument, it is automatically selected). The viewer always displays the name and number of the currently selected instrument. The viewer also displays a scrollable list of records containing the following items:

(a) Unique consecutive number (labelled “DTI Number” on the viewer screen) (b) Day of the week (c) Date (d) Time (e) A flag which shows ‘P’ for preset tare weighing, ‘A’ for semi-auto tare weighing,

‘B’ for both (for IH500 combined tare) or ‘G’ for gross weighing. (f) Gross weight (always available in mode ‘G’; blank if the data is not available) (g) Tare (blank if the data is not available) (h) Net weight in mode ‘P’ or ‘A’; blank in mode ‘G’

7

(i) Units of measurement (j) A ‘valid’ flag which shows ‘Y’ if the check code for the record is correct or ‘N’ if it

is incorrect. Additionally, if the check code is incorrect (indicating that the record has been altered in some way), the whole record is highlighted.

The viewer provides facilities for searching for a record by time and date, or by unique consecutive number. The viewer automatically searches all available datalog files belonging to the selected weighing instrument.
