A Reliable Memory Upgrade for Your MicroLogix System

The 1763-MM1 is a robust accessory module from Allen-Bradley. This device stores critical program and recipe data. It operates as a non-volatile memory unit for MicroLogix 1100 controllers. Your system retains data without needing a battery. This design prevents unplanned stoppages and production loss. The module reliably transfers programs between different controllers. It supports hot swapping, known as Removal and Insertion Under Power (RIUP). This feature allows for quick field changes without system shutdown.

Product Procurement & Buyer Guide for the 1763-MM1

Procurement teams require precise compatibility for their automation assets. The 1763-MM1 is engineered exclusively for the MicroLogix 1100 series. This module offers a storage capacity of 128 KB. It supports essential functions like recipe logging and write protection. The unit also features program compare capabilities. You can use it as a removable backup for your user programs. This action safeguards your intellectual property from accidental deletion. The module does not expand the controller’s built-in RAM. Instead, it provides an external repository for secure data transport.

Consider this module for applications needing portable program storage. It supports automatic data transfer to controller RAM at startup. This ensures your machine runs the correct recipe every time. The product lifecycle is at an end-of-life stage. Its discontinuation date was April 1, 2022. The official replacement product is the Micro 800 series. Verify your system’s compatibility before purchasing. This module is compliant with EMC, LVD, and RoHS regulations.

Step-by-Step Installation Guide for the 1763-MM1

Installing this module is a straightforward mechanical process. First, remove the protective port cover from your MicroLogix 1100. Then, align the 1763-MM1 with the mounting guides on the controller. Gently push the module into the slot until it seats firmly. If you feel unusual resistance, pull the module back. Re-align it carefully before attempting insertion again. Forcing the module can damage the connector pins.

The module supports live installation under power (RIUP). However, the controller requires a power cycle to recognize the hardware. You can also transition the controller to program mode. A suspend or faulted state will also register the change. The module uses a non-volatile memory type. It retains its contents without a backup battery. This feature eliminates the need for scheduled battery replacements. The memory automatically transfers data to the controller RAM on each boot.
