USB import & export

Where Backup & restore moves everything at once, import and export move one thing at a time. Use it to carry a screen you built on one cell to another, to bring in a company logo, or to keep a document under version control on a PC.

Everything here goes through the UD1: port and needs a FAT32 stick — see Installation for why, and what to do with a larger drive.

File types

Extension	Holds
.hmi	One document — every screen, control and tag it uses
.thm	One theme
.csv	A document’s tags, for editing in a spreadsheet
.png .jpg .jpeg .gif .bmp	Pictures, imported from the Images panel

A document carries its own tags, so exporting a .hmi and importing it on another controller brings the bindings with it. What it does not bring is the signals themselves: if the destination robot has the clamp on a different output, the tag still says DO[5] and needs repointing.

Exporting

1. Insert a stick into the UD1: port.
2. Open the Documents panel and choose the document.
3. Press Export and confirm the filename.

Themes export from the Theme panel and tags from the Tags panel, the same way.

Importing

1. Insert the stick and open the panel for the thing you are importing.
2. Press Import and pick the file from the list.

The picker lists only files of the matching type. Images are filtered to the formats the runtime can draw: .png, .jpg, .jpeg, .gif and .bmp.

An imported picture is copied onto the controller and becomes part of the document, so it travels with a .hmi export and is included in a backup. Its name is cleaned up on the way in and made unique against what is already there, so a picture may not keep exactly the name it had on the stick — and importing the same one twice leaves two copies under different names.

Importing a document that already exists asks first. Importing tags from a .csv merges by name.
