A binding is a correspondence between two entities that allows information be passed between them (either in one of the directions, or in both directions).

The main parts of binding are:

The types of bindings that are available depend on the binder in use (see further below). For the (most common) PointBinder, there is just one type of binding available, a PointBinding. The point binding can be e.g. for an OPC-DA item, an OPC-DA property, or for OPC-UA data (node attribute).

There may be multiple bindings associated with a control. With this feature, you can, for example, bind a value (converted to string) to the actual text box’s text, while binding the status information to its color.
