PLC / HMI program rescue and backup
When a controller is discontinued and the vendor is gone, the only copy of the machine program may live inside the machine. We read it out, verify it and archive it — with written authorization from the equipment owner.
What's included
- Remote feasibility assessment of the controller and connection route.
- Read-out of the user program and configuration (within authorized scope).
- Checksum / integrity verification against the running installation.
- Archive in an agreed, readable format with a documented version record.
What you receive
- The program file(s) and configuration you can keep yourself.
- A verification / checksum record and a short hand-over note.
- Optional off-site dual backup (see Program Asset Management).
Indicative pricing
from US$850 (CNY ¥6,000–12,000) per controller for standard scope. Reference rate: 1 USD ≈ 7.2 CNY. International projects are quoted at the time of quotation.
