Notable enums
The 25 enums map MTConnect's data-item taxonomy: availability states, execution states, controller modes, event categories, sample units. Each MTConnect data-item type that has an enumerated range gets a PHP enum.
Notable types
The three DTOs encode MTConnect's structured data-item samples and events — typed wrappers around the value + unit + qualifier trio MTConnect carries on every reported data-item.
