The invention provides, in some aspects, a process, environmental, manufacturing, industrial or other such control system (hereinafter, “control system”) with enhanced, real-time change tracking. The system includes one or more configurable elements (e.g., field devices), a change tracking system that records of changes to those configurable elements (e.g., for compliance reporting, etc.) and a change detection system that responds to detected changes in configuration of those element(s) by inferring an identity of a person and/or device responsible for a change, the time of the change, and/or the reason for the change. This is unlike prior art systems, in which that such information must be specified, e.g., in a data entry form filled-in by the field engineer, operator or other who is making the change.
1. A system for process, environmental, manufacturing or industrial control, comprising: one or more configurable elements that are coupled to a control network,a device that is coupled to the control network and that is capable of effecting a change to one or more of the configurable elements,a cha
1. A system for process, environmental, manufacturing or industrial control, comprising: one or more configurable elements that are coupled to a control network,a device that is coupled to the control network and that is capable of effecting a change to one or more of the configurable elements,a change tracking system that records changes to the one or more configurable elements, anda 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 combination thereof that is responsible for a change, the time of the change, and/or the reason for the change. 2. The control system of claim 1, wherein the change detection system infers-the identity of the person responsible for a change from information resident on the device and/or supplied by the device that made the change. 3. The control system of claim 2, wherein the device that made the change executes software that identifies the user who was operating that device at the time of the change. 4. The control system of claim 3, wherein the software queries the user for identifying information prior to making the change. 5. 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, anda 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. 6. The control system of claim 5, wherein the change detection system infers the identity of a person responsible for a change from a list of live users on a control network to which one or more of the configurable elements are coupled. 7. The control system of claim 6, wherein live users are users that are any of logged-in or active on the control network at the time a change is made. 8. The control system of claim 5, wherein the change detection system winnows down the list of live users to identify users with sufficient access and permissions to effect the signaled change. 9. The control system of claim 8, wherein the change detection system further winnows-the list to identify one or more of (i) users who are expected to make a change to the one or more configurable elements, and (ii) users who are not expected to make such changes. 10. The control system of claim 5, wherein the change detection system queries any of an asset management, employment, information technology, or other database, or a store to identify any of users and/or devices with potential access to the control network. 11. The control system of claim 5, wherein the change detection system infers-the identity of a person responsible for the change from information resident on and/or supplied by the device that made the change. 12. The control system of claim 11, wherein the device that made the change executes software that identifies the user who was operating that device at the time of the change. 13. The control system of claim 12, wherein that software queries the user for identifying information prior to making the change. 14. A method for process, environmental, manufacturing or industrial control, the method comprising: effecting a configuration change in one or more elements of a control system,detecting the change,with a change detection system, 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, andwith the change detection system, responding 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 any of logged-in or active on that network. 15. The method of claim 14, wherein the change detection system executes the step of inferring the identity of a person responsible for a change from a list of live users on a control network to which one or more of the configurable elements are coupled. 16. The method of claim 15, wherein live users are users that are any of logged-in or active on the control network at the time a change is made. 17. The method of claim 14, wherein the change detection system executes the step of winnowing down the list to identify users with sufficient access and permissions to effect the signaled change. 18. The method of claim 17, wherein the change detection system executes the step of further winnowing-the list to identify one or more of (i) users who are expected to make a change to the one or more configurable elements, and (ii) users who are not expected to make such changes. 19. The method of claim 14, wherein the change detection system executes the step of querying any of an asset management, employment, information technology, or other database, or a store to identify any of users and/or devices with potential access to the control network. 20. The method of claim 14, wherein the change detection system executes the step of inferring the identity of a person responsible for the change from information resident on and/or supplied by the device that made the change. 21. The method of claim 20, comprising executing, on the device that made the change, software that identifies the user who was operating that device at the time of the change.
