ABSTRACT:
Systems and methods that facilitate electronic audit recording and tracking of interactions in an industrial control system via employing a differentiation engine that supplies an object-oriented presentation of an audit trail—and further present a view of a desired segment associated with a PLC program (e.g., a particular run of the PLC program), for an object that an audit is requested for. A user (e.g., a customer of the industrial process) can initially identify an object and subsequently view typically all changes to such identified object. Accordingly, a general requirement for checking every version to determine a change to the object is mitigated.
