Features:
- The CPU provides 512 KB of integrated working memory for the active S7 program and data.
- Two isolated RS485 interfaces separate MPI-capable communication from an additional DP network role.
- A SIMATIC Micro Memory Card supplies load memory and maintenance-free program backup.
The processor scans the S7 program, updates the process image and exchanges configured data with central and remote modules.
The MPI/DP interface carries engineering, operator-panel and S7 services, while the second port can organize another PROFIBUS DP segment.
Stored diagnostic-buffer entries and online test functions connect controller events with the program and variables being examined.
The Siemens 6ES7317-2AJ10-0AB0 CPU 317-2 DP Processor Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Program and data storage
- Working memory: Integrated RAM holds the code and data used during CPU execution.
- Load memory: The required Micro Memory Card stores the loadable project and data.
- Backup path: Program and data backup is provided through the card without a battery.
- Retentive area: Data blocks can retain configured values within the supported retentive memory limit.
First-interface services
- Physical layer: The first port is an isolated RS485 interface.
- Engineering access: MPI services connect programming devices and operator panels.
- DP operation: The same port can be configured as a PROFIBUS DP master or slave.
- Routing: Configured communication services route data between supported S7 connections.
Dedicated PROFIBUS path
- Independent interface: The second isolated RS485 port does not provide MPI operation.
- Master role: The port can coordinate a separate group of PROFIBUS DP devices.
- Slave role: The CPU can instead expose configured transfer areas as a DP slave.
- Isochronous mode: This interface supports the documented OB 61 isochronous operating path.
Commissioning and event checks
- Block status: Online status links executing logic with current signal states.
- Variable checks: Inputs, outputs, memory, data blocks, timers and counters can be observed or controlled.
- Forcing: Selected input and output variables can be forced during controlled commissioning work.
- Event history: The diagnostic buffer retains 100 entries through a power interruption.
