Estimate memory requirements offline for controllers with divided memory

When a project changes on a controller with divided memory, use the
Estimate
 button on the
Capacity
 tab of the
Controller Properties
 dialog box to see the estimated memory usage and remaining available memory.
IMPORTANT:
This procedure applies to the CompactLogix 5370, ControlLogix 5570, Compact GuardLogix 5370, and GuardLogix 5570 controllers.
Some controllers, for example Compact GuardLogix 5380, CompactLogix 5380, CompactLogix 5480, ControlLogix 5580, GuardLogix 5580, and ControlLogix 5590 controllers, store all elements in one common area and the data values are automatically updated when the project changes.

    1. On the
      Online
      toolbar, click the
      Controller Properties
       icon.
    2. On the
      Controller Properties
       dialog box, click the
      Capacity
       tab.

     box, select the controller that has the correct memory size.
  3. View the memory information that is available since the last estimate.
  4. Select
