Features:
- The CPU executes a fail-safe S7-300 project engineered with STEP 7 and S7 Distributed Safety.
- A mandatory Micro Memory Card provides load storage and maintenance-free program and data backup.
- Two isolated RS-485 interfaces divide MPI/DP services from an additional PROFIBUS DP path.
Siemens 6ES7317-6FF04-0AB0 performs CPU 317F-2 DP control in a SIMATIC S7-300 station.
The first bus channel combines MPI with DP master/slave functions, while the second channel is dedicated to DP communication.
Safety engineering, the selected memory card, and both bus configurations are maintained in the validated controller project.
The Siemens 6ES7317-6FF04-0AB0 SIMATIC S7-300 CPU 317F-2 DP 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).

Safety Engineering Relationship
- CPU role: The 317F-2 DP executes the fail-safe and standard program areas assigned in the controller project.
- Engineering option: S7 Distributed Safety supplies the documented safety-program configuration path.
- STEP 7 baseline: The required software release and hardware support package identify this exact CPU version.
- Project integrity: Safety logic, hardware parameters, and distributed-I/O addresses remain part of one validated configuration.
First RS-485 Interface
- MPI services: The channel provides PG/OP communication, routing, global data, and S7 communication.
- DP master: The same port can control a configured PROFIBUS DP network.
- DP slave: The interface can alternatively participate as a DP slave.
- Role selection: The STEP 7 hardware project determines which communication mode is active.
Micro Memory Card Dependency
- Required medium: The CPU does not provide its documented load-memory function without a Micro Memory Card.
- Capacity range: Supported MMC storage extends to the documented 8 MB maximum.
- Backup function: Program and data backup is maintained through the MMC without a CPU battery.
- Execution relation: Stored project content supplies the integrated work memory used while the CPU runs.
Two PROFIBUS-Capable Channels
- Separated networks: The two isolated RS-485 interfaces can be assigned to different DP segments.
- Master capacity: Each configured master path controls the documented distributed-station set.
- Slave restriction: The CPU cannot operate as a DP slave on both interfaces at the same time.
- Diagnostic flow: Routing and process-diagnostic information follow the active interface roles in the STEP 7 project.
