The Allen Bradley 1766-MM1 MicroLogix 1400 Memory Module is an optional memory accessory developed for the Bulletin 1766 MicroLogix 1400 programmable controller family. It provides 384 KB of additional, separately stored memory for supported backup and program-transfer operations.
The module is useful in industrial environments where PLC programs need to be preserved, compared, or transferred between compatible controllers. Its supported functions include user program and data backup, data logging and recipe backup, program comparison, write protection, and automatic loading under configured conditions.
An important distinction is that the MicroLogix 1400 already uses non-volatile internal memory to retain its program and data when controller power is removed. The 1766-MM1 provides a separate backup medium rather than expanding the controller's internal user-memory capacity.
For maintenance teams, this additional storage option can simplify program management and support recovery procedures. Before loading a stored application, verify the target controller model, firmware revision, program configuration, and machine-specific settings.

Technical FAQs
Q1: What is the memory capacity of the 1766-MM1?
A: The 1766-MM1 provides 384 KB of memory for supported backup and storage functions.
Q2: Does installing the 1766-MM1 increase the MicroLogix 1400's internal user memory?
A: No. It provides separate backup storage and does not increase the controller's available user-program or data memory.
Q3: What types of information can the module back up?
A: Supported functions include user program, user data, data logging, and recipe backup.
Q4: Can the module transfer programs between controllers?
A: Yes. It can be used to transport stored programs between compatible MicroLogix 1400 controllers.
Q5: Does the 1766-MM1 support program comparison?
A: Yes. It supports comparing the stored user program with the program in the controller.
Q6: Can the memory module automatically load a program?
A: Yes. Automatic loading is supported through the controller's memory-module configuration and associated system settings. Review the controller manual before enabling this function.
Q7: Does the module provide write protection?
A: Yes. Its supported functions include write protection for the memory module and controller data files, helping prevent unintended changes.
Q8: Can the 1766-MM1 support recovery after a controller fault?
A: It supports an auto-recovery function that can restore the stored application through a controller power cycle when the relevant configuration and operating conditions are met.
Q9: What should be checked if the controller does not recognize the module?
A: Check that the module is fully inserted in the designated slot, inspect the connector for damage or contamination, and confirm that the controller is a compatible MicroLogix 1400 model.
Q10: Is the 1766-MM1 interchangeable with the 1763-MM1?
A: No. The 1766-MM1 is designed for MicroLogix 1400 controllers, while the 1763-MM1 is intended for MicroLogix 1100 controllers. They should not be treated as interchangeable.
