Features:

  • CompactFlash Memory Interface for ControlLogix and CompactLogix Controllers
  • Combines 64MB Non-Volatile Storage with Industrial-Grade Reliability
  • Operates in Conjunction with Allen-Bradley PLC Systems and RSLogix/Studio 5000 Software
The Allen-Bradley 1784-CF64 CompactFlash Memory Card serves as a dedicated storage solution for Allen-Bradley programmable logic controllers, providing reliable non-volatile memory for user programs, configuration data, and application files. It continuously stores critical control logic and system parameters, ensuring data retention during power cycles and supporting seamless operation of the overall automation system. The 1784-CF64 offers robust data integrity in industrial environments, and using this memory card enables quick program transfer between compatible controllers without requiring a direct programming connection.

The 1784-CF64 provides essential storage functions common to compatible controller families, and is a critical component of the control system data management path, directly affecting the proper backup and restoration of user applications. One 1784-CF64 memory card is typically required per controller for local program storage and data logging purposes. The 1784-CF64 occupies the dedicated CompactFlash card slot on compatible Allen-Bradley controllers and is always inserted in the designated CF card interface.

For system maintenance and program deployment applications, the Allen-Bradley controller platform supports direct use of the 1784-CF64 memory card for program loading and retrieval. In addition to standard controller operation, the 1784-CF64 also facilitates offline program development and field deployment. The Allen-Bradley CompactFlash configuration executes data transfer using the standard file system supported by the controller firmware.

The 1784-CF64 Allen BradleyCompactFlash Memory Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Allen-Bradley 1784-CF64 is a compact, industrial-grade Logic 556x card manufactured by Allen-Bradley. Belonging to the A series, it has a data storage capacity of 64 MB and weighs only 14.2 grams. Primarily used in the Allen-Bradley ControlLogix L6 controller, this industrial-grade storage unit provides non-volatile memory for the ControlLogix controller. The card is easy to install into the controller.

The Allen-Bradley 1784-CF64 serves as a secure, long-term repository for user applications and firmware, eliminating the need for manual program recovery. After a power outage, it automatically reloads lost user logic and updates system dependencies, allowing the processor to safely resume operation without manual intervention.

For installation and system integration, the Allen-Bradley 1784-CF64 is approved for seamless and direct hardware integration with older ControlLogix (1756-L6x, 1756-L6xS) and CompactLogix (1769-L32x, 1769-L35x) controller slots.

The 1784-CF64 compact memory card provides a permanent backup solution in the event of battery failure in ControlLogix devices and controllers. Data on the CompactFlash card can be used for archiving and recipe processing. The controller offers a scalable solution to I/O point issues. The ControlLogix controller is equipped with a communication port for direct connection to Ethernet-enabled devices and networks. To extend the memory card's lifespan, the 1784-CF64 compact memory card should be protected from electrostatic discharge and electromagnetic noise.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
In what scenarios should I use the Allen Bradley 1784-CF64?
It is ideal for safety-critical, non-stop industrial applications, such as fast program replication across multiple machines, battery backup replacement, and automatic recovery in unmanned remote stations.
What are the key installation and operation precautions for the Allen Bradley 1784-CF64?
Always insert or remove the card with the controller powered off. Do not hot‑swap the card when the CF activity LED is flashing, as this may corrupt data or damage the controller firmware. Use RSLogix 5000 to store/load projects.
How can I diagnose issues if the Allen Bradley 1784-CF64 is not recognized?
Check the controller’s “OK” and “CF” LED status. If the card fails to read/write, inspect the gold-plated contacts for contamination. For discontinued models, contact Rockwell Automation support for verified replacement options (e.g., 1784-CF128 — please confirm with official support).
How does the Allen Bradley 1784-CF64 perform in terms of speed and monitoring?
It provides stable read speed optimized for I/O throughput. Through RSLogix/Studio 5000, you can monitor card capacity, remaining space, file system integrity, and configure load triggers (power‑up, user‑triggered, or on‑error loading).
What environmental conditions can the Allen Bradley 1784-CF64 tolerate?
It operates from 0 °C to 60 °C, withstands 5% to 95% non-condensing humidity, and meets industrial shock and vibration standards (15G vibration, 1500G shock).
