Updating global events through the GUI
Action | Result
--- | ---
Auto revert | Updating the events through the controller GUI or the web GUI are ignored, if the program is marked as a global event in ToolsTalk 2. The update is made and sent back to ToolsTalk 2 where the change is recognized but not acknowledged. The original global event program is then immediately pushed back to the controller.
Unlink | Updating the events through the controller GUI or the web GUI causes the program to change from a global event to a local event, in the affected controller. The update is made and sent to ToolsTalk 2 where the change is recognized. As a result the event is immediately removed from the distribution list to the controller.

The selection of auto revert or unlink must be made when a global event is configured for distribution to a controller. The selection cannot be changed at a later stage.
