# Fieldbus Configuration Library - Creating a Global Fieldbus Configuration from an Existing Fieldbus Configuration

1. Select a controller (containing the desired fieldbus configuration) in the Plant structure workspace .

2. Select Fieldbus & SoftPlc in the menu bar.

3. In the Fieldbus menu select one or more fieldbus signal configurations to add to the library. Select Manage then Add to library from the drop-down menu.

   - The Create global configuration dialog window opens. Select Create.

4. The selected local configuration will become a global configuration, stored in the Global Fieldbus configuration library.

   If local changes are made in the controller or web GUI, the two options below are available:

   - Auto revert: Changes in the controller will not apply to the global fieldbus configuration, the global configurations will still be applied.

   - Unlink: Changes in the controller will apply to the fieldbus configuration in the controller, and the link to the global configuration will be cut. As a result, the global fieldbus configuration is immediately removed from the distribution list to the controller.

5. Select Library in the left-side menu bar.

6. Go to Global fieldbus library .

   The workspace shows a list of Global fieldbus configurations and the newly added fieldbus configuration is now visible in the list.
