1784 Industrial CompactFlash Cards
CompactFlash cards offer nonvolatile memory (flash) to permanently store a user program and tag data. You install the 1784 CompactFlash card in a socket on the controller. You can manually trigger the controller to save to or load from nonvolatile memory or configure the controller to load from nonvolatile memory on powerup.
The CompactFlash card offers nonvolatile memory (flash) to permanently store a user program and tag data on a controller. The 1769-L3x, 1768-L4x, amd 1768-L4xS controllers support a CompactFlash card.

1769 CompactLogix Batteries
The 1769-L23x and 1769-L3x controllers come with one 1769-BA lithium battery. The 1768 controller does not require a battery. The controller uses internal flash memory to store its program during shutdown. Energy stored in the 1768 power supply maintains controller power long enough to store the program to internal flash memory (not the external CompactFlash card).
