Features:
- The CPU 317F-2 DP provides 1024 KB of work memory for standard and safety programs.
- An MPI/DP interface and a second DP master/slave interface separate communication roles.
- A SIMATIC Micro Memory Card and S7 Distributed Safety engineering are required.
Siemens 6ES7317-6FF03-0AB0 executes standard and fail-safe logic as the central processing unit in a SIMATIC S7-300 station.
Its first MPI/DP connection and second PROFIBUS DP master/slave interface must be restored with their original network parameters.
The safety project, Micro Memory Card, F-DB handling, hardware release, and firmware context belong together during exchange.
The Siemens 6ES7317-6FF03-0AB0 SIMATIC S7-300 CPU 317F-2 DP may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Fail-Safe Processing Context
- Application scope: The CPU is designed for personnel, machine, and burner safety tasks.
- Safety software: Use S7 Distributed Safety V5.2 SP1 or higher with the documented STEP 7 environment.
- Consistency control: Resolve an inconsistent safety program before returning the CPU to operation.
- Version record: The product information covers hardware release 01 and firmware V2.1.10 onward.
Two-Interface Bus Layout
- First interface: MPI/DP communication is supported up to 12 Mbit/s.
- Second interface: The second PROFIBUS connection can operate as DP master or slave.
- Restoration record: Preserve station addresses, baud rates, termination, and device assignments for both interfaces.
Work and Process Memory
- Work memory: The CPU provides 1024 KB for program execution.
- Process image: Inputs and outputs each use a 1024-byte process-image area.
- Retentive data: Up to 256 KB of data blocks can be configured as retentive.
- Load storage: A SIMATIC Micro Memory Card is required.
Safety Data-Block Boundaries
- Creation control: F-DBs must be generated and handled through the supported safety engineering workflow.
- Deletion control: Manual changes to F-DB structure can invalidate safety-program consistency.
- Retentive data: Verify F-DB retentivity and startup behavior against the archived safety project.
- Exchange rule: Preserve the project signature, MMC contents, and documented CPU version together.
