Siemens 6ES7511-1FK01-0AB0 is the SIMATIC S7-1500F CPU 1511F-1 PN, a failsafe central processing unit for safety-related automation tasks. The official configuration provides 225 KB program work memory, 1 MB data work memory, 60 ns bit performance and one PROFINET IRT interface with an integrated two-port switch. A SIMATIC Memory Card is required. The listed hardware functional status is FS03 and the firmware version is V2.9. The CPU includes a 3.45 cm display, six keys and one mode selector. Safety project, firmware, memory-card and distributed device compatibility require documented validation before commissioning.
The configured PROFINET network supplies standard and safety-related process information.
Standard and failsafe program sections are processed within the validated automation project.
Controller outputs and diagnostics follow the configured safety and machine-control logic.
