A project for the industrial controller is developed that includes multiple components. Each of the components may be arranged at varying levels. Authorized personnel are able to access the components, or a portion thereof, within the industrial controller to change settings and or programming of the industrial controller. As each change is made, the industrial controller maintains a log of the changes. The change may initially be recorded in each module and/or at each level of the project. The change is then rolled up to a top level of the project. A revision log at the top level of the project stores each of the changes within the industrial controller. The industrial controller may then access the revision log to determine whether any action needs to be taken within the industrial controller."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus to track changes in an industrial controller","description":"A method and apparatus for tracking changes in an industrial controller is disclosed.
