slot number

slot number

The number that indicates the physical location of the slot in the chassis where the controller resides. If you enter a slot number that is out of range for the specified chassis, you will receive an error message when you apply your changes. The slot number cannot be changed when online.

In ControlLogix, controllers occupy a numbered slot in the chassis and can be placed in any slot. It is also possible to place multiple controllers in the same chassis.

For SoftLogix controllers, the default value is 1. You also have the option to place modules in slot 0.

For CompactLogix, DriveLogix, and FlexLogix, since the controller always resides in slot 0 of the virtual backplane, this field is disabled, and slot number 0 is displayed.

For Safety controllers, valid values range from 0 to two less than the number of slots in the chassis (for example, in a 10-slot chassis, valid values will range from 0 to 8).
