# Applications

The **Applications** section lets you select and control programs developed in SunriseWorkbench and deployed to the controller. Open it with the **Applications** button in the smartHMI navigation bar.

## Application list

The application selection page has two columns:

| Column | Description |
|---|---|
| Robot applications | Control programs started manually by the operator |
| Background applications | Programs that run automatically as a `backgroundTask` |

Each list entry contains:

- a **status indicator** — the colored dot to the left of the name;
- the **application name** — the Java class name;
- the **package** — namespace or category such as `[application]`, `[ros]`, or `[demo]`;
- a **checkbox** — used to select or deactivate the application.

The **Reset selected robot application** button (hand icon) clears the active application selection without stopping it. Running background applications are shown with a green dot and a **Stop** button.

## Selecting and activating an application

Click an application name in the list to select it. The selected application is highlighted in orange, its checkbox is selected (✓), and its name appears in the smartHMI navigation bar. The system automatically opens the **Application control** page, which shows the current program state and execution log.

## Application states

### Activated

A gray circular indicator means that the application has been selected and loaded into the controller but has not started yet.

### Running

A green play indicator means that the program is running. Events defined by the developer appear in the log in real time. If the program requires operator interaction, a selection dialog appears over the log.

### Motion paused

A yellow pause indicator means that execution has been interrupted. Resume the program in the same way it was started.

### Error

A red indicator means that an unhandled exception occurred during execution. The status line displays the error code. Logic errors must be corrected in SunriseWorkbench.

## Deactivating an application

Open **Applications**, find the active application (orange highlight and selected checkbox), and click its checkbox to deactivate it.
