Bindings to Tag Properties
Aside from binding a property to a Tag's value, you can also bind to properties on a Tag, such as Tooltip, Quality, or AlarmActiveAckCount. This is useful when you don't need the value of the Tag, but rather the state, or some other configuration on the Tag. Here we see a boolean Memory Tag. It has a property indicating the Tag's quality. We can easily display that quality property on a component.
The simplest approach involves a Tag Binding. This can be achieved by dragging-and-dropping the Tag Property onto a Window, component, or component property. For example, you can drag a Tag's Quality property to a Label component.
This is similar to creating a standard Tag Binding, except we're using a property on the Tag instead of the Tag's value. The resulting Tag Binding would be:
Note that the property name has been appended to the path.
The Label component now displays the current value of Good for the Tag's Quality property.
