# FIeldbus Configuration Library

The fieldbus configuration can be either Global or Local.

A Local fieldbus configuration is valid for a single controller and a Global fieldbus configuration is valid for several selected controllers.

A controller can subscribe to Global fieldbus configurations. Whenever any changes are made to a configuration it propagates to all controllers in ToolsTalk 2 that subscribe to the configuration.

The Global fieldbus configurations library manages the global fieldbus configurations and the controllers that subscribe to the configurations.

Updates to subscribers are done within the ToolsTalk 2 application. All affected controllers will show the Push indicator in the Line structure workspace.

ToolsTalk 2 can distinguish between a local and global fieldbus configuration, although the controller itself has no knowledge of this. Therefore it is important to specify the action in ToolsTalk 2 if a fieldbus configuration is changed via either the controller GUI, or the web GUI.
