Features:
- Executes standard and fail-safe programs in one SIMATIC S7-300 CPU.
- Provides 512 KB of work memory with a required Micro Memory Card.
- Connects field devices through MPI/DP and a two-port PROFINET interface.
Safety and standard program sections share the controller while remaining governed by their own engineering and validation rules.
The removable MMC carries the load-memory content needed to restore the CPU after a hardware exchange.
Network recovery depends on matching the saved DP addresses, PROFINET device names and project hardware configuration.
The Siemens 6ES7315-2FJ14-0AB0 CPU 315F-2 PN/DP Safety Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Keeping the fail-safe project consistent
- Project signature: The archived safety project should be matched to the running installation before hardware is exchanged.
- Authorization: Password and access information must be available for safety-program changes and acceptance.
- F-runtime groups: Configured execution groups preserve the intended separation and response of the fail-safe tasks.
- Acceptance test: Safety functions require documented validation after the restored CPU is returned to operation.
Preparing program recovery
- Work memory: The CPU provides 512 KB for active code and data used by the standard and safety tasks.
- Load medium: A SIMATIC Micro Memory Card is required to hold the project for loading and restart.
- Process image: Configured input and output areas must agree with the restored hardware layout and user program.
- Backup scope: Program blocks, hardware configuration and safety parameters should be archived together.
Restoring both communication paths
- MPI/DP port: The combined interface can serve programming, MPI or PROFIBUS DP functions according to the project.
- PROFINET ports: The integrated two-port switch links Ethernet devices without requiring a separate panel switch for the local line.
- Device identity: PROFINET names and IP settings must match the project before distributed I/O can exchange data.
- Bus records: DP addresses, baud rate and termination should be recorded before removing the installed CPU.
Returning the controller to RUN
- Engineering versions: The STEP 7 and S7 Distributed Safety releases must support the CPU hardware and firmware level.
- MMC check: The card should contain the correct project and be seated before a controlled power-up.
- Diagnostic buffer: Startup events can identify missing hardware, network mismatches or an inconsistent safety program.
- Functional proof: Standard sequences and every safety function should be verified before production resumes.
