Appendices : Appendix H: Units Upgrade 12.0.SP6 to 12.1 : The Process

When entering Schematic Model Manager, if an Upgrade is recommended a message box will be displayed.

The message box will be shown if the units UDAs, which were mandatory in 12.0 SP6, (Pmguntsangle, Pmguntsarea, Pmguntsdist, Pmguntpres, Pmguntstemp, Pmguntvolm, Pmguntweig) are present on SCDIAGRAM elements in the project and have a value other than "unset". It adds the Units Upgrade menu options to the Schematic Model Manager Tools menu and the Lexicon Schematic Model Manager Menu.

If the user decides that the Units Upgrade is not required they can select the check box for "Don't show this again" and the warning will no longer be shown and the Units Upgrade Menu options will no longer be available. This information is stored in the Project Options file.

Step 1 - Pre-Upgrade Scan

Step 1 analyses the Schematic data and generates a file containing the elements and attributes which have been identified as upgrade candidates. The file can then be checked and if required can be amended to remove items from the upgrade. Refer to Checking and Amending the XML file Generated in Step 1 for more information.

The UDAs with data which should be dimensioned are identified and the suggested dimensions given in the XML file. Any Schematic Model Manager mandatory UDAs and any customer defined UDAs will be identified. The Attribute Mappings are used to identify attributes where units are associated to the data.

Use the Tools menu option Schematic Model Manager to run Step 1.

On successful completion of Step 1 the user will see a message box which will give details of the location of both the XML file and the log file produced and will also list the Dictionary databases which have been identified. The foreign Dictionary databases will list separately as these will need to be upgraded where they are mastered, it is suggested that the user makes a note of all the Dictionary databases which are reported so that they can make sure that Step 2 is run for each of them.

This step should be run for all Schematic Databases, using a particular Dictionary database, before the Dictionary database is upgraded in step 2.

Step 2 - Upgrade Dictionary Database(s)

Step 2 will upgrade the UDAs identified in Step 1 for the Dictionary databases that are accessible. The UDAs will have the UUNI set to the dimension stated in the XML file. Make sure Step 1 has been run on all the Schematic Databases that use the UDAs defined in this Dictionary Database before running Step 2.

Use the option in the Schematic Model Manager menu to run Step 2

The user will be asked to select a file produced by Step 1 to use and will be shown a file open dialog.

On successful completion of Step 2 the user will see a message box which will ask if they have other Step 1 file which they want to use. Selecting Yes will show the file open dialog to choose another file. Selecting No will take them to a summary message box which will list all the files they have run for Step 2 and the Dictionary databases that have been processed.

At the completion of Step 2 all the UDAs on Elements in the Schematic Databases will have a unit associated with the value. For example a Temperature may now have the value 32degC when previously it just read 32. At this point none of the values for the attributes identified in Step 1 have been converted so if your data was imported using degF and the value was 78 the value would now be set to 78degC and is therefore incorrect. Step 3 will convert the values so that the data is correct.

Step 3 - Upgrade Schematic Database Values

Step 3 uses the XML file created in Step 1 to set the values for the attributes so that they are correctly stored according to the Units for the dimension type.

Use the Tools menu option in Schematic Model Manager to run Step 3.

On completion of Step 3 all data has been upgraded to use the new units functionality in 12.1. The units UDAs which were mandatory in Schematic Model Manager (Pmguntsangle, Pmguntsarea, Pmguntsdist, Pmguntpres, Pmguntstemp, Pmguntvolm, Pmguntweig) at 12.0 SP6 will be set to "unset" and the project options will be updated to show that the Upgrade has been completed. The units UDAs will still be available but will no longer be maintained or used by Schematic Model Manager. They are not included in the Schematic Model Manager UDAs defaults at 12.1.
