Configure any routine as the fault routine for a program. The routine
executes when a program fault occurs before the controller transitions to
fault mode.

1. Open the project in the Logix Designer application.
2. In the Controller Organizer, right-click MainProgram and select
Add>New Routine.
3. On the New Routine dialog box, in Name, type the name of the
routine.
