Add an Unassigned I/O Device to a Safety Controller

You can add devices to the Unassigned folder and then assign devices to a controller as the safety project develops. You can also use the Unassigned folder to move devices between controllers.
IMPORTANT: Unassigned safety I/O devices do not have a Safety Network Number (SNN).
FactoryTalk® Design Studio™
 automatically generates the SNN when you assign the safety I/O device to a safety controller.
  1. In Devices explorer, right-click the Unassigned folder and select New device...
