Methods and apparatus for control configuration with enhanced change-tracking

A system for process, environmental, manufacturing or industrial control, comprising:

• one or more configurable elements,
• a change tracking system that records changes to the one or more configurable elements, and
• a change detection system that is in communications coupling with the one or more configurable elements and with the change tracking system, the change detection system responding to detected changes in one or more of those elements by inferring at least one of an identity of a person, a device, and a combination thereof that is responsible for a change, the time of the change, and/or the reason for the change, wherein the change detection system responds to a change alert signaling indicating that the configuration of a configurable element has been changed by querying a control network to which that element is coupled for a list of users that are logged-in or active on the network.
