Magelis HMI Project Recovery Guide

Evidence-safe preparation questions for locating, validating, and preserving legacy Magelis HMI project materials before repair or migration.

Legacy HMI recovery starts with identifying every available engineering asset: source files, runtime files, software versions, communication settings, media, and backups. What can be recovered from a terminal varies by model, configuration, condition, and how the project was originally deployed.

Direct Answer

Do not assume the terminal contains a reusable editable project. Inventory existing backups and media first, preserve the current unit, and have a qualified controls professional confirm what can be retrieved or reconstructed.

Inventory before attempting recovery

Document the exact terminal reference, installed software generation, visible storage media, network and serial connections, and every known project archive before changing the device.

  • Preserve removable media without overwriting it and create a controlled copy where qualified procedures permit.
  • Confirm the supported retrieval method for the exact terminal and project configuration before connecting or uploading.

When the screen is damaged

A partially functioning unit may still contain useful configuration or project evidence, but recovery options vary. Avoid destructive resets, downloads, firmware changes, or media initialization until the current state is documented and a recovery plan is approved.
