Components
Components are building blocks for your project. The Vision Module has a variety of built-in components such as displays, buttons, charts, and other elements that display information. Each component has multiple properties that control its appearance, behavior, and data. For example, a Tank has a level, capacity, and a liquid color, while a Label has text, font, and an image. You can enhance components with custom properties to create additional functionality.

Bindings
A binding is a mechanism that allows a property on a component to change based on a a change to a value elsewhere in Ignition. For example, with binding, the liquid level displayed in a tank graphic can be bound to the realtime liquid level in a tank. The value of a Tag could be bound to a linear scale, a meter, or a label on your window. The power of bindings comes from the variety of binding types.
