Description

The Siemens S7-1500 CPU 1511F-1 PN (catalog number 6ES7511-1FK02-0AB0) is a fail-safe CPU designed for safety-oriented automation systems where both standard and safety control are required in a single processor. Part of the S7-1500 F-series, this model supports applications up to SIL 3 (IEC 62061) and PL e (ISO 13849-1), making it ideal for industries with rigorous safety demands—such as packaging, material handling, automotive assembly, and process automation. In addition to its 150 KB of work memory (50 KB for standard logic and 100 KB for data), the 1511F-1 PN allows safe programming and execution of fail-safe routines via the Safety Integrated functionality in the TIA Portal. Safety functions such as emergency stop, guard door monitoring, and two-hand control can be implemented directly within the controller. All safety and standard programming are handled in a unified environment using Step 7 Safety Advanced. It integrates a PROFINET interface for real-time communication, diagnostics, and interaction with distributed I/O (including fail-safe ET 200 modules). The CPU is modular and expandable, with support for signal, communication, and function modules. With its compact footprint, extended diagnostics, and high-level security integration, the 1511F-1 PN delivers robust control with comprehensive protection—ideal for future-ready safety automation.
