Tag Binding

A tag binding is a very straight-forward binding type. It simply binds to a tag property. This sets up a tag subscription for that tag, and every time the chosen property changes, the binding is evaluated, pushing the new value into the property.

If the tag is in a leased scanclass, this binding will activate the lease while the window is open.

If you choose a tag in the tree, and not a property, the Value property is assumed.

Bidirectional Mode

Choosing bidirectional will make this binding also write to the chosen tag when the property changes. The fallback delay is the amount of time to keep the property at the written value waiting for a new tag value update to come in. If no update arrives within the given timeout, the property falls back to the original value. See Bidirectional Bindings.

Overlay Opt-Out

Choosing this option will ignore the quality of the chosen tag, making it have no effect on the component's quality overlay.
