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.
Claims14
A system, comprising:
- one or more processors;
- one or more memory communicatively coupled to at least one of the one or more processors, the one or more memory having stored therein computer-executable instructions, comprising:
- a differentiation engine configured to generate an audit trail of logged real time interactions with an industrial control object, wherein the real time interactions comprise changes to the industrial control object in a plurality of versions of the industrial control object;
- and
- a view selection component configured to display a version of the industrial control object and to display changes between the version of the industrial control object and another version of the industrial control object.
A method, comprising:
- generating recording, by a device including a processor, an audit trail of logged real time interactions with an industrial control object, wherein the real time interactions comprise changes to the industrial control object in a plurality of versions of the industrial control object;
- and
- displaying, by the device, a version of the industrial control object, and changes between the version of the industrial control object and another version of the industrial control object.
A non-transitory computer-readable medium having instructions stored thereon that, in response to execution, cause at least one device to perform operations comprising:
- recording changes to an industrial control object in a plurality of versions of the industrial control object, and
- displaying a version of the industrial control object, and changes between the version of the industrial control object and another version of the industrial control object.
