Modify a Named Historic Region

You can change the settings of an existing Historic Region so that it has a different:

• Name
• Start Time
• Duration

This is especially useful when you need to increase or reduce the amount of historic data included in a Historic Region.

To edit an existing named Historic Region:

1. Access the ClearSCADA Server Configuration Tool, (see Accessing the ClearSCADA Server Configuration Tool).
2. Expand the Database Configuration branch.
3. Select Historic Regions.
4. Right-click on the background of the list of historic regions.
   A context-sensitive menu is displayed.
5. Select the Modify option to display the Modify Historic Region window.

   

6. Use the Modify Historic Region window to adjust the settings as required. The settings are identical to those on the Add Historic Region window (see Create a Named Historic Region).
7. Select the OK button to close the Modify Historic Region window and confirm the changes.
8. Right-click on the system icon in the tree-structure, and select the Apply Changes option to apply the changes.

Now that you have modified a historic region, you can either proceed to configure other Historic settings (see Historic Configuration Settings) or you can continue with the server configuration.
