Features:
- The CPU executes S7-300 control logic in 128 KB of integrated work memory.
- MPI provides engineering communication while a separate isolated DP interface serves distributed PROFIBUS stations.
- A Micro Memory Card stores the load project and enables maintenance-free program recovery.
Siemens 6ES7315-2AG10-0AB0 coordinates local rack modules and the configured PROFIBUS process image.
The MMC of 6ES7315-2AG10-0AB0 links the physical CPU to its saved program, hardware configuration, and communication parameters.
Diagnostic resources on 6ES7315-2AG10-0AB0 help separate CPU, rack, and DP network faults during commissioning.
The Siemens 6ES7315-2AG10-0AB0 CPU 315-2 DP Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Stored Program and CPU Recovery
- Load memory: The supported MMC carries the project blocks and hardware configuration.
- Power recovery: The CPU restores the stored program from the card without a backup battery.
- Card capacity: The selected MMC must fit the complete load project within the documented maximum.
- Replacement check: MMC contents, firmware, and CPU order number are verified before the processor is exchanged.
Programming and S7 Communication
- Engineering route: MPI provides the documented programming connection to STEP 7.
- Network identity: Each MPI participant requires an address that is unique on the configured segment.
- Connection resources: Programming, operator, and S7 communication share the available MPI connections.
- Bus setup: Cable, connectors, termination, and transmission rate must agree across the segment.
Second PROFIBUS Interface Roles
- Master role: The isolated interface coordinates cyclic data with the configured DP slave stations.
- Slave role: The same interface can present the CPU as a DP slave under another master.
- Role selection: The STEP 7 hardware project determines which operating role and address are active.
- Data path: The configured DP process image links field data to the executing CPU program.
Status, Buffer and Commissioning
- Central rack: The CPU controls the local S7-300 modules through the backplane bus.
- Expansion units: Interface modules extend the station to the documented number of additional racks.
- Event history: The diagnostic buffer records CPU, module, and communication conditions.
- RUN decision: The processor enters RUN only after the configured hardware and network conditions are accepted.
