The
Allen-Bradley 1762-MM1 is the memory-module-only accessory for MicroLogix 1200 controllers. It provides removable nonvolatile storage for one controller user program and its associated data, supporting controlled backup, recovery and application transfer.
The module can be inserted or removed with power applied when no data transaction is active. The controller recognizes it after a power cycle or after entering a non-executing mode, and its write-protection function is a write-once/read-many setting that cannot be removed.
The 1762-MM1 Allen-Bradley MicroLogix 1200 Memory Module may still be available for purchase and support from Moore Automated beyond End-Of-Life (EOL) by the manufacturer (OEM).

Program Backup Use Cases
- Validated user-program backup
- Controller recovery after service
- Application transfer without a programming computer
- Protected distribution of a machine program
1762-MM1 stores one MicroLogix 1200 user program and its data. It is suited to maintenance strategies that require a controlled recovery copy, a portable application image or a protected program for replacement controllers.
Program compare can verify the relationship between the controller application and the stored copy. Data-file download protection and permanent write protection help control how the saved application is restored or distributed.

The module supports user-program and data backup, program comparison, data-file download protection and write protection. Rockwell Automation identifies 1762-MM1 as discontinued and assigns an Engineering Replacement category without specifying a direct replacement catalog number.
Installation and Configuration
- Observe electrostatic-discharge precautions
- Do not insert or remove during a data transaction
- Use a power cycle or non-executing mode for recognition
- Confirm write-protection requirements before storage
Before installation, verify that the target controller is an Allen-Bradley MicroLogix 1200 and confirm its catalog number, firmware, memory-module slot and approved application. The memory module may be inserted or removed with power applied only when a data transaction is not in progress.
After insertion, power-cycle the controller or place it in a non-executing mode so it recognizes the module. Because write protection is write-once/read-many and cannot be removed, validate the final program and data set before enabling protection.
