=== Detailed Step-by-Step Operation ===
The HMI is your primary control panel for the production line, allowing you to oversee operations, adjust settings, and diagnose basic issues.
[[File:Line Layout.jpg|thumb|313x313px]]

==== Step 1: Navigating the HMI ====
Your HMI screen typically displays a main overview of the production line. You can move between different screens by using the arrow buttons or dedicated icons (like a house icon for the home screen) that appear on the display.

==== Main Production Overview Screen ====
This is your central hub, providing a visual representation of your production line.

* '''Production Line Diagram:''' You will see a simplified diagram of the various stages of the production process. This helps you quickly see the overall status.
* '''Reset Button:''' If the line experiences an issue or needs to be cleared, press the "Reset" button to bring the system to a safe, initial state.
* '''Current Product Display:''' The HMI will show the name of the product currently being processed or the last selected product.

==== Production Status Screen ====
This screen provides real-time information about the line's performance.

* '''Product Idle Time:''' This indicates how long the product has been in a non-moving or waiting state at a specific point on the line. It helps you identify potential bottlenecks.
* '''Product Speed:''' This shows the current operating speed of the product moving along the conveyor. You may also see indicators for the minimum and maximum allowed speeds.
* '''Tray Gap:''' This monitors the distance between trays on the conveyor. It's important for consistent product flow and helps prevent jams. You may also see indicators for optimal spacing.
