Overview Manuals MMC & Retention PROFINET I/O MPI & DP Diagnostics

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.
Description
Siemens 6ES7317-2EK13-0AB0 is a SIMATIC S7-300 CPU 317-2 PN/DP central processing unit with 1 MB of work memory. It executes the controller program while one MPI/PROFIBUS DP interface and one Ethernet/PROFINET interface connect engineering, fieldbus, and distributed I/O networks.

A Micro Memory Card supplies the load-memory and maintenance-free backup path for 6ES7317-2EK13-0AB0. After power returns, the CPU restores the stored project from the approved card, while retentive work-memory areas preserve only the values defined by the hardware configuration.

Through the PROFINET connection, 6ES7317-2EK13-0AB0 exchanges cyclic I/O data with configured devices and exposes TCP/IP, ISO-on-TCP, UDP, diagnostics, and a read-only web server. The separate MPI/DP path maintains access to PROFIBUS stations and service devices without sharing the Ethernet medium.

The diagnostic buffer of 6ES7317-2EK13-0AB0 records CPU and communication events for STEP 7 analysis. A replacement must retain the exact project, firmware context, MMC contents, station addresses, PROFINET device names, and PROFIBUS settings before the process network can return to service.

FAQS

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 can 6ES7317-2EK13-0AB0 remain in STOP after a CPU exchange?
Siemens 6ES7317-2EK13-0AB0 can remain in STOP when the MMC project, hardware configuration, firmware context, or configured I/O differs from the installed station.
Why can PROFINET devices stay unavailable after replacing 6ES7317-2EK13-0AB0?
If device names or IP settings no longer match the 6ES7317-2EK13-0AB0 project, the IO controller cannot bind the intended stations.
What should be preserved before removing 6ES7317-2EK13-0AB0?
Archive the 6ES7317-2EK13-0AB0 STEP 7 project, MMC contents, firmware and hardware status, network names, addresses, and bus topology.
How are intermittent fieldbus faults traced on 6ES7317-2EK13-0AB0?
Read the 6ES7317-2EK13-0AB0 diagnostic buffer in time order and compare its events with PROFINET topology, PROFIBUS termination, and module status.
Can 6ES7317-2EK13-0AB0 start without its Micro Memory Card?
No. Siemens 6ES7317-2EK13-0AB0 requires the approved MMC because the card provides the load-memory and project-recovery path.
What limits the 128-device PROFINET capacity of 6ES7317-2EK13-0AB0?
The practical 6ES7317-2EK13-0AB0 limit also depends on update times, data volume, communication connections, and the complete project resource load.
