Wiring Manager supports Ferrule Numbering. When Ferrule Numbering is used, each wire end may have a different number (that is, each end [ferrule] of a wire is numbered instead of there being a single number for the wire).
Note: Whether or not ferrule numbers are generated for newly connected screens and earth cores is controlled by the Generate Ferrule data for Cable Screens and/or the Generate Ferrule data for Cable Earth Cores checkboxes on the General Tab of the Options window.
In Wiring Manager, a Ferrule Number is stored for each wire end. The default value is empty (blank).

In the above example, all the Ferrule Numbers are independent and have been set to a specific value required for the current project/plant standards.
When Ferrule Numbers are used, Wiring Manager continues to create and update Signal Numbers as terminations are created and changed.
Ferrule Numbers always override Signal Numbers in document, as explained above.
Ferrule Numbers can be manually set or removed using the Terminations window (see Manual Ferrule Numbering). Automatic Ferrule Rules can also be set up for the project so they are automatically created as wire and cables are terminated (see Automatic Ferrule Numbering.
