PLC and HMI backup audits locate missing source code, verify what is actually recoverable, and set out the steps to restore production after a control system failure.
We start by finding out what equipment is installed and what documentation or source code is actually available. A backup is only useful if it can be found and the recovery route is understood.
Locate and verify source code
We identify where PLC and HMI programs are held, check that backups are complete, and flag any gaps before they matter.
Recover programs where possible
Where an original project can be recovered from controllers or surviving copies, we restore it. Where it cannot, we assess what can be rebuilt.
Plan recovery to limit downtime
We develop disaster recovery plans that set out who acts, in what order, and how production returns following a PLC, HMI or control system failure.
