Memory Cards
Memory cards offer nonvolatile memory to permanently store a user program and tag data on a controller. The 1756-L7 ControlLogix controllers come with a 1784-SD1 Secure Digital card already installed. The 1756-L6 controllers support optional CompactFlash cards that you purchase separately. Through RSLogix 5000 software, 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 GuardLogix controller does not support user program storage or retrieval by using a CompactFlash card.

1756 Energy Storage Modules
Instead of a battery, the 1756-L7 controllers ship with a 1756-ESMCAP energy storage module (ESM) already installed. The ESM eliminates the need for a battery.
| Attribute | 1756-ESMCAP | 1756-ESMNSE | 1756-ESMNRM |
| Description | Capacitor-based Energy Storage Module | Energy storage module without WallClockTime back-up power | Nonremovable capacitor-based energy storage module |
| Use | Ships with the controller | Use this ESM if your application requires that the installed ESM deplete its residual energy to 200 mJoule or less before transporting it into or out of your application. Additionally, you can use this ESM with a 1756-L73 (8 MB) or smaller memory-sized controller only. | Secures the controller by preventing the USB connection and access to SD card removal. If the SD card is installed prior to insertion of the 1756-ESMNRM module, the SD card remains functional, but not removable. |

Replacement Batteries
Each ControlLogix controller ships with a battery. The 1756-L6 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.

1756-BATM battery module |
| ⋆ The 1756-BATM externally mounted battery assembly is highly recommended for use with all series A 1756-L6x controllers and provides longer battery life than the 1756-BA1 battery. The 1756-BATM includes one 1756-BATA lithium battery assembly and a 1 m (3.28 ft) cable to connect housing to controller. ‡ The 1756-L55M22, 1756-L55M23, and 1756-L55M24 controllers have nonvolatile memory and can be used without a battery. |
