Lock the alias definition list

You can lock the Alias definition list so that:

• the Aliases in derived instances and templates cannot be edited

• users cannot change the Alias configuration at run time

• changes are propagated from templates to instances

The following actions are not allowed if the Alias definition list is locked:

• Adding, renaming or deleting Aliases

• Assigning attribute references to Aliases

• Importing Aliases

  Note: When either the Step Program or the Alias configuration is locked, certain constraints apply. When the Step Program template is locked, an Alias referenced by the Step Program cannot be deleted or renamed. Importing an Alias configuration that does not include all of the Aliases referenced by the Step Program fails.
