Allen-Bradley 1756-L7SP ControlLogix Processor

The Allen-Bradley 1756-L7SP GuardLogix Safety Partner Processor is the dedicated safety processing node in a GuardLogix system, designed to operate in a two‑processor safety configuration alongside a main GuardLogix CPU to execute safety tasks and monitor safety I/O. It communicates across the GuardLogix network fabric using Ethernet/IP, ControlNet, DeviceNet, Data Highway Plus, Remote I/O, SynchLink, and other networks supported within the GuardLogix ecosystem, enabling integrated safety communications with field devices and I/O modules. For safety tasks, GuardLogix controllers support Ladder Diagram programming, with the 1756-L7SP serving as the safety partner while the primary controller handles non‑safety logic and sequencing. As part of the GuardLogix 5570 family, the L7SP is intended for applications that require a clearly separated safety processor within a multi-processor safety architecture, providing a streamlined path to safety functionality without deploying a separate safety PLC.
