These controllers have nonvolatile memory and can be used without a battery.
†The 1756-L6x controllers have nonvolatile memory if you install a 1784-CF64 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 they were when the nonvolatile memory was saved.
