Important: Deadband actions are no longer supported. Any configured deadband actions are ignored.

A deadband action changes the time and/or value storage deadband for one or more tags that are using delta storage. (Value deadbands only apply to analog tags.) Deadband change actions are useful for increasing data storage based on an event occurring. For example, an event detector has detected that a boiler has tripped, you might want to start saving the values of certain tags at a higher rate to help you determine the cause of the trip.
