Scoping brief · OEM-orphaned recovery
Recovering controls when the OEM is gone, the in-house team is thin, and parts are obsoleted.
OEM-orphaned control system recovery — reverse-engineering, replacement-panel retrofit, and lifecycle extension delivered under one crew, one schedule, one PO. The line stays under your operation’s control at every handoff — the documentation stays with you.
When the OEM disappears, your PLC parts go to six-week lead, your support ticket queue goes nowhere, and the operator-interface language drifts away from anything your maintenance crew can read. The line keeps running on borrowed time until it doesn’t — Kraytek puts it back into service on the current vendor stack.
Scope of a rebuild
Common recovery scenarios
Drawn from Kraytek recovery work — no fabricated specs, no SKU counts, no lead-time numbers. Each scenario is one engagement shape; the recovery scope comes from the walkdown.
- Orphaned ControlLogix/PLC-5 firmware
- Archived documentation
- Replacement-panel retrofit
- Lifecycle extension
Delivered
One procurement chain, one installation crew, one commissioning sign-off. Reverse-engineering, replacement-panel retrofit, and lifecycle extension written against the original asset — current vendor stack underneath, same mechanical footprint.
- Audit walkdown → ranked problem list engineering reads
- Reverse-engineering of original controls, alarm hierarchy, I/O map
- Replacement-panel retrofit written against the original asset
- Lifecycle-extension on mature platforms — vendor-current spares
- Documentation + spare-parts plan so the next decade of service stays in-house
- One procurement chain, one installation crew, one commissioning sign-off
Customer
Walkdown access and what engineering reads to write the first scope. No asset images, no formal spec sheets — just the information a recovery engineer needs to rank the problems.
- On-site walkdown access — original controls stack, mechanical condition, fault history, and the support tickets that go nowhere
- The asset name + line type (e.g. ControlLogix/PLC-5 migration, replacement-panel retrofit, lifecycle extension)
- A sentence or two on the symptom — six-week spares lead, archived documentation, support queue going nowhere
Process
How the engagement runs
Assessment
On-site walkdown of the asset: original controls stack, mechanical condition, fault history, and the support tickets that go nowhere. Output: a ranked problem list engineering reads to write the first recovery scope.
Migration plan
Reverse-engineering, replacement-panel retrofit, and lifecycle-extension plan written against the original asset — current vendor stack underneath, same mechanical footprint, same operator-interface language.
Cutover with documentation handoff
Re-assembly, commissioning, and re-validation under one crew, one schedule, one PO. A documented asset your own team can service without Kraytek on the phone — the documentation stays with you.
