Features:
- One megabyte of work memory supports the CPU 317-2 PN/DP program and data areas.
- Separate MPI/PROFIBUS DP and Ethernet/PROFINET interfaces connect legacy and Ethernet I/O networks.
- A Micro Memory Card stores the load project and provides maintenance-free backup.
Siemens 6ES7317-2EK13-0AB0 executes local control while coordinating PROFIBUS and PROFINET device data.
The MMC of 6ES7317-2EK13-0AB0 couples the hardware replacement workflow to the stored STEP 7 project.
Diagnostic and web-server resources on 6ES7317-2EK13-0AB0 expose controller and network status without replacing engineering access.
The Siemens 6ES7317-2EK13-0AB0 CPU 317-2 PN/DP Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Load Memory and Power Recovery
- Load project: The approved MMC contains the program and configuration required by the CPU.
- Maintenance-free backup: Program and data can be restored from the card without a backup battery.
- Retentive area: Only the configured retentive work-memory range preserves values across a restart.
- Exchange control: Card contents and CPU firmware must be validated before fitting a replacement processor.
Ethernet Device Coordination
- Controller role: The CPU exchanges cyclic process data with the configured PROFINET IO devices.
- Device identity: Station names and IP settings bind the configured devices to the controller project.
- Transport services: TCP/IP, ISO-on-TCP, and UDP provide the documented Ethernet communication paths.
- Web diagnostics: The read-only web server provides browser access to supported controller status.
Engineering and PROFIBUS Path
- Combined interface: The isolated RS485 port operates as MPI or PROFIBUS DP according to the project.
- DP master role: Configured PROFIBUS slaves exchange cyclic data with the CPU over this interface.
- Engineering access: MPI provides the documented programming and service route for compatible stations.
- Commissioning check: Addressing, termination, baud rate, and bus topology must match the saved project.
Event History and Replacement Checks
- Buffer depth: The integrated diagnostic buffer retains up to 500 documented events.
- Fault sequence: Time-ordered entries help separate a network failure from a CPU or module event.
- Project match: Hardware configuration must match the physical rack and distributed stations.
- Return to service: PROFINET names, PROFIBUS addresses, MMC contents, and firmware are verified before RUN.
