6. Enter the slot number of the controller.
The New Controller dialog box displays the slot location of the safety
partner based on the slot number entered for the primary controller.
If you select a slot number for the primary controller that does not
accommodate placement of the safety partner immediately to the right of
the primary controller, you are prompted to re-enter a valid slot number.
7. Specify the folder in which to store the safety controller project.

9. Click OK.
The Logix Designer application automatically creates a safety task and a safety
program.
A main ladder logic safety routine called MainRoutine is also created within the
safety program.
Figure 6 - Safety Task in the Controller Organizer
A red bar under the icon distinguishes safety programs and routines from
standard project components in the Controller Organizer.
When a new safety project is created, the Logix Designer application also
automatically creates a time-based safety network number (SNN).
This SNN defines the local chassis backplane as a safety subnet. It can be viewed
and modified via the General tab on the Controller Properties dialog box.
For most applications, this automatic, time-based SNN is sufficient. However,
there are cases in which you might want to enter a specific SNN.
