Backup & restore
Back up every document and image, and restore them onto a controller.
Backup writes everything the HMI holds — every document and every imported image — onto a USB stick in one pass, along with a manifest describing what it wrote. Restore reads that stick back onto a controller.
It is separate from backing up the controller (programs, registers, system files), which is a button action an operator can run from a screen.
Taking a backup
Section titled “Taking a backup”- Insert a FAT32 USB stick into the
UD1:port of the controller. - Open the Documents panel in the editor.
- Press Backup.
Progress is shown file by file. When it finishes you will have one .hmi file
per document, every image, and a backup.txt manifest.
The manifest is written last, so a stick carrying documents but no manifest is an interrupted backup. Restore reports that rather than restoring part of a cell.
If the stick already holds a backup, you are asked before it is replaced.
Restoring
Section titled “Restoring”- Insert the stick and open the Documents panel.
- Press Restore.
- Review what will be installed, then confirm.
Restore reads the stick first and tells you what it found, including documents whose id already exists on this controller — those are replacements, not additions.
Images referenced by a document are restored alongside it. An image that is on neither the stick nor the controller is reported rather than silently dropped.
