PLC program change and backup log
A chronological record linking approved PLC and HMI changes to files, revisions, online edits, temporary conditions, backups, and evidence.
Field problem
A change can work in production yet leave no reliable record of the starting file, who edited what, whether forces were removed, or where the final backup was stored.
What is inside
- System, file, revision, hash, software, firmware, backup, storage, and verification baseline
- Chronological edit, import, parameter, download, firmware, and HMI transfer activity log
- Online edit, force, override, authorization, removal, and verification record
- Post-change backup, open check, secondary copy, functional verification, evidence, storage, and handoff fields
