Features:
- Fail-safe and standard application code can run on the same S7-300F CPU.
- Integrated work memory is 192 KB, with 384-byte input and output process images.
- MPI and PROFIBUS DP interfaces support controller, engineering, and distributed I/O communication.
For personal and machine safety, burner controls, and standard automation tasks, Siemens 6ES7315-6FF01-0AB0 combines both program types in one CPU.
The 6ES7315-6FF01-0AB0 memory organization reserves defined resources for standard data while safety data blocks follow separate retentive behavior.
During commissioning, 6ES7315-6FF01-0AB0 engineering software, safety-package level, hardware release, and firmware must be checked as one supported combination.
The Siemens 6ES7315-6FF01-0AB0 CPU 315F-2 DP Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Fail-Safe Memory Behavior
- Work memory: The CPU provides 192 KB of integrated work memory.
- Standard data: Up to 128 KB is usable as data memory for standard applications.
- F-data blocks: Safety-program data blocks are not retained after power cycling or STOP-RUN restart.
- Block restrictions: Defined SFC operations cannot create, delete, or target F-DBs.
Distributed Communication Role
- DP interface: The integrated PROFIBUS DP port connects distributed stations and controllers.
- I-slave mode: The CPU can operate as an intelligent slave in a DP network.
- Station loss: DP-master failure can extend I-slave program processing by up to 20 ms.
- MPI path: The MPI interface supports engineering and SIMATIC communication tasks.
Safety Program Startup Diagnostics
- Consistency test: A supported safety project is checked for internal consistency during startup.
- STOP response: Detection of an inconsistent safety program moves the F-CPU to STOP.
- Diagnostic record: The event is written to the CPU diagnostic buffer for troubleshooting.
- Initial values: F-DBs restore their defined load-memory initial values after restart.
Project Compatibility Requirements
- Hardware scope: The product information applies from hardware release 01.
- Firmware scope: The documented CPU baseline begins at firmware V2.0.1.
- Safety package: S7 Distributed Safety is required for fail-safe application engineering.
- Project validation: STEP 7, safety-package, firmware, and project versions must be checked together.
