The Allen-Bradley 1756-L64 ControlLogix PLC Processor is the 5564-class central controller in Rockwell Automation’s ControlLogix family, commonly referred to as the Logix5564 processor. It includes 16 MB of user memory, providing space for large ladder logic, structured text, and data-tracking programs within a single module. As the primary processing unit in ControlLogix systems, it coordinates controller logic with I/O modules on the same backplane, enabling reliable automation for complex manufacturing lines. Typical applications include factory automation, batch processing, and high-speed machine control where a robust, rack-mounted PLC processor is required.
