Machine Passport
PT-104
Line 03 / Pump skid
PLC, HMI, variable-frequency drive
An example of how a proposed Machine Passport organizes one machine’s records. These filenames, dates, and evidence states are fictional. No machine or live AI is connected.
The evidence, with its limits.
A state describes the evidence available for that item. It does not certify recovery of the whole machine. The example names records; it does not provide the underlying files.
| Record | State / example date | What the state means |
|---|---|---|
| PLC program filePT104_baseline.L5X, v4 | Located | A file is identified. Its match to the current controller and its usability still require confirmation. |
| Electrical drawingE-104, revision C | Reviewed | The record has been reviewed in this example. Review does not by itself establish current machine accuracy. |
| Drive parameter recordPT-104 VFD, isolated test | Restore-tested | A test is recorded for an isolated setup. Its environment, outcome, and reviewer would belong in the actual record. |
| HMI restore evidenceOperator panel, test record | MissingNot recorded | No restore-test evidence is supplied for the HMI. Its recovery path remains unconfirmed. |

Questions for qualified review.
- Confirm the equipment identities and required software.
- Confirm record ownership, access, revisions, and current relevance.
- Locate HMI evidence, manuals, and maintenance history.
- Review the recorded drive test’s scope and limitations.
- Agree any further assessment or approved nonproduction test separately.
A filename is not proof of a usable backup. A file, paper printout, or tag read does not by itself prove a current recovery path. An individual drive test does not prove the PLC, HMI, or whole machine can be restored. Qualified people retain decisions under the site’s approved procedures.
