Summary

Datalinks are used to define where data comes from in the database and are attached to Attributes as Extended Entity Data.

There are two types of Datalinks: Keywords (predefined) and SQL statements (which are user definable)

Datalinks can be used to fill in values to a single attribute and they may be nested within each other and/or concatenated within character strings

Datalinks are attached and edited from within AutoCAD by selecting the desired block containing attributes with the menu AVEVA Instrumentation > Edit Datalinks command.

Blocks may be copied with Datalinks within AutoCAD to reduce setup time (and to copy entire drawings)

A list of predefined keywords within the Designer Drawing List for any selected drawing can be viewed by using the Show Datalinks option on the List Tools - Drawings tab (after selecting a drawing in the Drawing List), which opens the Datalinks Window.
