Industrial CompactFlash Cards

CompactFlash cards offer nonvolatile memory (flash) to permanently store a user program and tag data on a ControlLogix controller. 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 power up.

The GuardLogix controller does not support user program storage or retrieval by using a CompactFlash card.

Replacement Batteries

Each ControlLogix controller ships with a battery. The 1756-L6x controllers have nonvolatile memory if you install a 1784-CF64 or 1784-CF128 industrial CompactFlash card. With nonvolatile memory, the controller can be used without a battery. If you do not use a battery, current tag data will be at the state it was when the nonvolatile memory was saved.
