Controlled document handover
Replace “manuals included” with a document register that names every file, revision, language, editable/native format, owner, approval state and delivery gate.
Assign a document number, title, responsible party and applicable equipment tag so operators can connect the file to the delivered machine.
PDF is useful for issue control, while editable/native files may be needed for approved maintenance and backup. State both requirements and access limitations before order.
Not every file is useful if first delivered after the decision it supports.
Record the delivered PLC/HMI program version, hardware target, backup media, access method and restoration instruction. Where feasible, witness a controlled backup or restore check.
The project-specific register commonly covers layouts, utility and interface schedules, electrical and pneumatic schematics, manuals, parts and spare lists, certificates within scope, FAT records, packing records and agreed PLC/HMI or device backups.
Issue decision-critical files before approval or FAT, shipment-critical files before release, and corrected as-built files after site changes. Put each required version and gate in the contract register.
Not always. PDF supports controlled reading, while approved maintenance may require native drawings, software projects, parameter backups, licenses or restoration instructions. Define the required formats and access rights before order.
Document register
A document package is complete only when the buyer can identify the applicable machine and revision, open the required language and format, locate parts and safely recover agreed control backups.
| Register field | Required detail | Verification |
|---|---|---|
| Identity | Document ID, title, equipment tag and responsible author | Matches delivered equipment |
| Control | Revision, status, issue date and superseded version | Latest approved/as-built issue |
| Usability | Language, PDF/native format, software and access requirements | Buyer can open and maintain it |
| Delivery gate | Approval, pre-FAT, shipment, SAT or final as-built | Available before its decision |
| Backup recovery | PLC/HMI/device version, media, access and restore instruction | Recorded backup/restore check where agreed |
