Store and load a project by using a memory card Chapter 1
Prevent a major fault during a load
If the major and minor revisions of the project on the memory card do not match
the major and minor revision of the controller, a major fault may occur during a
load.
The memory card stores the firmware for projects for revision 12.0 or later.
Depending on the current revision of the controller, you may be able to use the
memory card to update the firmware of the controller and load the project.
Read/write card data
Sample ladder logic code for the Logix Designer applications are available for using
your file system on a Logix5000 controller to read and write data on a memory
card. These are the files you need:
• CF_Read_Write.ACD
• CF_Read_Write_Example.ACD
• Logix-AP007B-EN-P.pdf
To access these files, see

CompactFlash card formatting
The Logix Designer 1784-CF128 CompactFlash card does not have to be
formatted to store controller information.
