Features:
- The CPU executes standard and fail-safe control programs in one SIMATIC S7-1500F station.
- Separate program and data work-memory areas keep code storage distinct from runtime process values.
- A two-port PROFINET IRT interface connects distributed I/O and engineering communication through one integrated switch.
The retentive data area preserves selected timers, counters, flags and data-block values across a restart, while the project determines which values are retained.
A hardware clock supports synchronization through the automation system or NTP over Ethernet, giving program events a common time base.
The CPU can coordinate as many as 32 distributed I/O systems, with communication modules extending the station when additional bus connections are required.
The Siemens 6ES7511-1FK02-0AB0 CPU 1511F-1 PN Fail-Safe Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Project and runtime memory roles
- Program area: The 225 KB program memory holds executable control blocks for standard and fail-safe tasks.
- Data area: The 1 MB data memory stores runtime data blocks separately from program code.
- Load path: A SIMATIC Memory Card is mandatory and provides up to 32 GB of plug-in load memory.
- Retention: Selected timers, counters, flags and data-block values can use the 128 KB retentive area.
Integrated Ethernet control interface
- Port arrangement: X1 contains two RJ45 ports connected through the CPU's integrated switch.
- Controller mode: The interface can manage up to 128 PROFINET IO devices, including as many as 64 IRT devices.
- Device mode: The same interface can operate as a PROFINET IO Device and participate in shared-device configurations.
- Timing services: IRT, isochronous operation and direct data exchange align cyclic communication with the control task.
Standard and fail-safe program boundary
- Fail-safe CPU: Safety program blocks execute alongside the standard user program in the same processor.
- Safety protocol: PROFIsafe V2.4 and V2.6 carry safety-related process data through PROFINET.
- Block depth: Up to eight nesting levels are available for F-block execution within a priority class.
- Access protection: Display passwords, write protection and block protection restrict changes to the loaded project.
Configuration checks before download
- Software release: Firmware V2.8 integrates with STEP 7 TIA Portal V16 or a later supported version.
- Legacy project path: Older TIA Portal versions can configure the hardware as 6ES7511-1FK01-0AB0.
- Station size: One rack can contain the CPU and as many as 31 additional modules.
- Address space: Inputs and outputs each use a 32 KB address area, with every input included in the process image.
