        • PRODUCT OVERVIEW

          What is this product?

          Siemens 6ES7317-2AJ10-0AB0 is a SIMATIC S7-300 CPU 317-2 DP central processing unit with 512 KB work memory, an MPI/DP interface operating up to 12 Mbit/s, and a second PROFIBUS DP master/slave interface. The official CPU comparison information lists a 256-byte input process image and a 256-byte output process image for this hardware. A SIMATIC Micro Memory Card is required for program and data storage, while Siemens firmware information records V2.6.10 with STEP 7 V5.4 SP2. The CPU supports S7 routing and must be matched to the existing rack, bus addresses, distributed-I/O assignment and saved hardware configuration. Siemens classifies this article as an end-of-lifecycle spare part and names 6ES7317-2AK14-0AB0 as the successor; because the successor has a different memory specification, migration should be engineered rather than treated as a like-for-like exchange.

        • APPLICATIONS

          Where it may be used

          Use this CPU only in an S7-300 station whose rack, Micro Memory Card, MPI/DP network, distributed-I/O configuration and STEP 7 project match the documented CPU 317-2 DP hardware. Verify the firmware level and successor migration requirements before commissioning.

          PROFIBUS Master Coordination

          Operates the second interface as a DP master for a validated distributed-I/O configuration.

          DP Slave Station Integration

          Supports a documented PROFIBUS DP slave role when the existing STEP 7 project requires it.

          MPI/DP Engineering Access

          Provides the first MPI/DP interface at up to 12 Mbit/s for programming and network service.

          Legacy CPU317 Replacement

          Restores an existing CPU 317-2 DP station after the MMC, firmware and project data are verified.

      Information

      Overview Manuals PROFIBUS Configuration Memory Card and Project Data Upgrade

      Features:

      • 512 KB integrated work memory supports the documented CPU 317-2 DP program and data requirements in an S7-300 station.
      • The first MPI/DP interface operates at up to 12 Mbit/s while the second PROFIBUS DP interface supports master or slave configuration.
      • A SIMATIC Micro Memory Card is required, and the complete hardware, firmware and STEP 7 project must be checked before replacement.
      Siemens 6ES7317-2AJ10-0AB0 is a SIMATIC S7-300 CPU 317-2 DP with 512 KB work memory and two configurable MPI/PROFIBUS DP communication interfaces. Siemens records firmware V2.6.10 for this article, lists it as an end-of-lifecycle spare part and identifies 6ES7317-2AK14-0AB0 as the successor.

      Source reference: Siemens SiePortal product record and official SIMATIC S7-300 CPU firmware documentation.

      Exact-item verification and sourcing support are available for 6ES7317-2AJ10-0AB0.
      Siemens 6ES7317-2AJ10-0AB0 pdf, product information and verified S7-300 resources Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

      PROFIBUS Configuration

      The first interface combines MPI and PROFIBUS DP communication at up to 12 Mbit/s. The second interface can be engineered as a DP master or DP slave; addresses, baud rates, bus termination and the saved STEP 7 hardware configuration must match the installed station.

      Memory Card and Project Data

      Operation requires a SIMATIC Micro Memory Card. Before exchanging the CPU, preserve the verified STEP 7 project, record the installed firmware and PROFIBUS settings, and confirm that the MMC contents and hardware configuration belong to the exact 6ES7317-2AJ10-0AB0 station.

      Successor Planning

      Siemens names 6ES7317-2AK14-0AB0 as the successor to this discontinued CPU. The successor has a different memory specification, so replacement requires an engineering review of the project, MMC, firmware, communication load and distributed-I/O configuration before commissioning.

      Technical notes

      Siemens 6ES7317-2AJ10-0AB0 is documented as a SIMATIC S7-300 CPU 317-2 DP with 512 KB work memory, one MPI/DP 12 Mbit/s interface, a second PROFIBUS DP master/slave interface and a required SIMATIC Micro Memory Card. Siemens records firmware V2.6.10 with STEP 7 V5.4 SP2 and identifies 6ES7317-2AK14-0AB0 as the successor. Before replacement or commissioning, verify the complete article number, hardware and firmware versions, MMC contents, rack power conditions, PROFIBUS addresses and the saved STEP 7 hardware configuration.

      Complete CPU Identity Review

      Confirm the complete Siemens order number 6ES7317-2AJ10-0AB0, CPU 317-2 DP type marking, hardware and firmware versions, and the installed Micro Memory Card before replacement. The MPI/DP address, second-interface DP master or slave role and saved STEP 7 hardware configuration must agree with the existing station. If any suffix or nameplate data is unclear, provide a clear label photograph for exact matching.

      Quotation Data for CPU317-2 DP

      For an accurate quotation, provide the required quantity, complete 6ES7317-2AJ10-0AB0 order number, CPU nameplate photograph, hardware and firmware information, Micro Memory Card details, connected S7-300 rack or PROFIBUS equipment, receiving country and required delivery date.

      PRODUCT & ORDER FAQS

      Questions buyers ask about 6ES7317-2AJ10-0AB0

      • How can the exact 6ES7317-2AJ10-0AB0 CPU be identified?

        Check the complete Siemens order number, CPU 317-2 DP type marking, hardware and firmware information, and the Micro Memory Card used by the installed station. Send a clear nameplate photo if any marking is uncertain.

      • Is every CPU 317-2 DP interchangeable with this article?

        No. Confirm the full order number, firmware level, 512 KB work-memory requirement, MPI/DP network settings, PROFIBUS DP master or slave role, and the existing STEP 7 project before substitution.

      • Which communication interfaces are provided on this CPU?

        The official product record specifies a first MPI/DP interface operating up to 12 Mbit/s and a second PROFIBUS DP interface that can be configured as master or slave.

      • What should be checked before installing this S7-300 processor?

        Back up the STEP 7 project, verify the S7-300 rack and power supply, confirm the required Micro Memory Card, record both PROFIBUS addresses, and match the hardware and firmware configuration before power-up.

      • What is the Siemens lifecycle status and named successor?

        Siemens marks 6ES7317-2AJ10-0AB0 as an end-of-lifecycle spare part and identifies 6ES7317-2AK14-0AB0 as the successor. Migration is not automatic because memory and project compatibility must be reviewed.
