Product Overview
The Allen-Bradley 1763-MM1 is a 128 KB non-volatile memory module built for the MicroLogix 1100 controller family. It stores recipe and program data and moves programs between controllers without a laptop. Because the 1763-MM1 is end of life since 1-Apr-22, every spare unit already in stock protects a running line from an unplanned stop. Oil AutoTech keeps ready-to-ship spares for oil, gas and industrial automation sites.

Key Parameters and Cost Impact
128 KB Non-Volatile Memory
The 128 KB capacity holds program and recipe data without a battery. Non-volatile memory keeps its contents when power drops, so a brownout does not erase a working program. That single feature avoids restart labor and lost batches after an outage.
Write Protection
Write protection locks stored data against accidental overwrite. Operators can swap modules between identical machines without risking the master program — fewer programming hours, fewer scrap events.
Removal and Insertion Under Power (RIUP)
RIUP lets technicians fit or pull the module while the controller stays energized. Maintenance windows shrink, and production resumes faster. Note that the controller must be power-cycled or moved to program, suspend or faulted mode before it recognizes the new module.
Recipe Logging and Program Compare
Recipe logging supports product changeovers on the same line. Program compare verifies that the running program matches the stored copy, catching unauthorized edits before they cause defects.

Installation Notes
Remove the port cover shipped with the PLC. Align the module with the mounting guides and push gently. If you feel unusual resistance, pull back and restart insertion. The module fits with or without power applied; this does not damage the controller or the module. Power-cycle the controller, or enter program, suspend or faulted mode, to register the hardware change.
Compatibility and Integration
The 1763-MM1 works only with MicroLogix 1100 controllers. It does not increase the controller’s built-in memory — it adds a removable backup and a transfer medium. For sites migrating to the Micro 800 platform, this module keeps legacy MicroLogix 1100 assets productive during the transition. Confirm cabling and gateway needs with your supplier before ordering.
Selection and Maintenance Advice
Verify your controller model and current program size before buying. Inspect the module slot periodically for dust and secure seating, and follow the manufacturer’s safety manual for all maintenance. Because the 1763-MM1 is discontinued, stock is finite. Contact Oil AutoTech today for pricing and availability.
FAQs
Is the 1763-MM1 still available?
It reached end of life on 1-Apr-22. Availability depends on remaining stock, so confirm with Oil AutoTech before ordering.
Does the 1763-MM1 increase MicroLogix 1100 memory?
No. It adds 128 KB of non-volatile storage for program and recipe backup; it does not expand the controller’s built-in memory.
Can I install it while the controller is powered?
Yes. RIUP is supported. Power-cycle the controller or enter program, suspend or faulted mode so it recognizes the module.
Does it support data logging?
No. Data logging is not supported. Recipe logging is supported.
What replaces the 1763-MM1?
The listed replacement path is the Micro 800 platform. Contact Oil AutoTech for migration guidance.
