Store and Load Projects Using Nonvolatile
Memory
Using 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 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.
ATTENTION: Do not remove the memory card while the controller is reading
from or writing to the card, as indicated by a flashing green OK status indicator.
This could corrupt the data on the card or in the controller, as well as corrupt the
latest firmware in the controller. Leave the card in the controller until the OK
status indicator turns solid green.
