Configured for nonvolatile data retention in ControlLogix programmable automation controllers, the Allen-Bradley 1784-CF64 (1784-CF64 Memory Card) provides physical program storage and data logging execution. The hardware serves as the primary CompactFlash medium utilized to store control logic, process documentation, and firmware images across ControlLogix platforms.

Hardware Specifications

ControlLogix Deterministic Network Compatibility

The 1784-CF64 is engineered to maintain firmware flash compatibility with various ControlLogix controller revisions. By facilitating nonvolatile storage, it ensures that deterministic network configurations and process data remain intact during power loss events. The card supports high-speed data access, allowing for rapid controller reboots and the retention of critical instructional sets required for multidiscipline control environments, including motion and complex process sequences.

Frequently Asked Questions

Q: Can the 1784-CF64 be hot-swapped while the controller is running?

A: While the hardware may support insertion/removal in non-hazardous locations, it is standard practice to verify the controller status via software to ensure no active data logging is occurring.

Q: Is this memory card compatible with all ControlLogix controller firmware versions?

A: Compatibility is dependent on the specific controller module profile; consult the latest Rockwell Automation release notes to verify if 64 MB capacity is supported by your hardware revision.

Q: How do I recover data if the card is removed during a write cycle?

A: Abrupt removal during a write cycle can corrupt the file system. Use the controller's onboard diagnostic tools or primary programming software to attempt a reformat or file restoration if the card is not recognized.
