iX Developer

4.16 Aliases

An alias should be treated as a property of a screen and can act as a stand-in for a tag. The alias can be used to reference a tag wherever that tag can be referenced directly. When used, iX Developer will act the same as if the original tag had been used. Each screen using aliases can be configured with a different instance different tag references.

Using aliases will enable reuse of screens without having to create a new duplicated screen.
