Allen-Bradley CPUs

Allen-Bradley CPUs (Central Processing Units) are the core components of their PLC platforms, providing the processing power and memory management for industrial automation systems. The ControlLogix series includes processors like the 1756-L8xE that offer multiple core architectures and memory options ranging from 2MB to 40MB, supporting complex applications with demanding processing requirements. The CompactLogix processors, such as the 1769-L3x series, provide similar capabilities in a more compact form factor. These CPUs support multiple programming routines simultaneously, handle real-time control tasks, and manage communication across various industrial networks. Advanced features include Store and Load (SSL) capabilities for program transfers, redundancy options for critical applications, and security features like digital signatures and change management. The processors are designed with diagnostics capabilities and battery-backed memory to maintain program integrity during power loss events.
