Store and Load Projects Using Nonvolatile
Memory
Use Memory Cards for
Nonvolatile Memory
GuardLogix® 5570 controllers support a memory card for nonvolatile memory.
Nonvolatile memory lets you keep a copy of your project on the controller. The
controller does not need power or a battery to keep this copy.
You can load the stored project from nonvolatile memory to the user memory
of the controller:
• On every powerup
• Whenever there is no project in the controller and it powers up
• Anytime through the Studio 5000 Logix Designer® application

IMPORTANT Nonvolatile memory stores the contents of the user memory at the time that
you store the project:
• Changes that you make after you store the project are not reflected in
nonvolatile memory.
• If you make changes to the project but do not store those changes, you
overwrite them when you load the project from nonvolatile memory. If
this occurs, you have to upload or download the project to go online.
• If you want to store changes such as online edits, tag values, or a
ControlNet™ network schedule, store the project again after you make
the changes.
