More Information

Overview Manuals MMC Project MPI Service DP Master/Slave Rack Diagnostics

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.
Description
Siemens 6ES7315-2AG10-0AB0 is a SIMATIC S7-300 CPU 315-2 DP central processing unit with 128 KB of work memory. It executes the controller program while an integrated MPI interface and a second PROFIBUS DP master/slave interface connect engineering and distributed I/O.

A Micro Memory Card provides the load-memory and project-recovery path for 6ES7315-2AG10-0AB0. The CPU reads the stored hardware configuration, blocks, and communication parameters from the supported card, so an exchange requires the validated MMC and the correct firmware context.

The two RS485 paths on 6ES7315-2AG10-0AB0 serve different network roles. MPI supports programming and S7 communication, while the isolated second interface operates as the configured DP master or slave and exchanges cyclic data with PROFIBUS stations.

Status LEDs and the diagnostic buffer of 6ES7315-2AG10-0AB0 identify CPU, module, and fieldbus events for STEP 7 troubleshooting. Commissioning must verify rack modules, station addresses, termination, transmission rate, MMC contents, and the physical DP topology before switching the processor to RUN.

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does 6ES7315-2AG10-0AB0 request a Micro Memory Card?
Siemens 6ES7315-2AG10-0AB0 uses the MMC as its load-memory and maintenance-free project-recovery medium.
Why can 6ES7315-2AG10-0AB0 remain in STOP after fitting a replacement?
A mismatched MMC project, firmware context, rack configuration, or DP network can keep 6ES7315-2AG10-0AB0 in STOP.
Can the second interface of 6ES7315-2AG10-0AB0 be both DP master and slave at once?
The STEP 7 project assigns the documented DP operating role of 6ES7315-2AG10-0AB0; commissioning must follow that selected configuration.
What should be checked when DP slaves disappear from 6ES7315-2AG10-0AB0?
Check 6ES7315-2AG10-0AB0 bus addresses, connectors, end termination, cable continuity, baud rate, slave power, and the saved hardware project.
How are sporadic rack or fieldbus faults diagnosed on 6ES7315-2AG10-0AB0?
Read the 6ES7315-2AG10-0AB0 diagnostic buffer in sequence and compare its events with module LEDs and PROFIBUS station status.
What must be archived before removing 6ES7315-2AG10-0AB0?
Preserve the 6ES7315-2AG10-0AB0 STEP 7 project, MMC image, firmware and hardware status, MPI/DP addresses, and rack layout.
