      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • Siemens 6ES7952-1KM00-0AA0. In an S7-400 maintenance workflow, Flash media preserves a loadable application image separately from CPU execution memory.
      Product type: MC 952 memory card
      System: SIMATIC S7-400
      Memory technology: 5 V Flash EPROM
      Capacity: 4 Mbytes
      The long-design card contains 4 Mbytes of 5 V Flash EPROM. Its nonvolatile storage role is distinct from RAM and from the CPU work-memory allocation. Match the complete card reference and supported host CPU before transferring the application.

      The MC 952 technical table specifies a typical operating current of 40 mA and a maximum of 90 mA at 5 V for this order number. Flash is listed without a backup-current requirement. The card capacity alone does not define the host CPU power or memory limits.

      Program-transfer and startup checks must retain the approved application version and the CPU hardware configuration. A replacement card must contain the intended project image before the machine is released. Verify the CPU-specific procedure and compare online diagnostics with the retained project record.
      Controller platform reference: Siemens SIMATIC S7-400.
      Technical downloads for Siemens 6ES7952-1KM00-0AA0: a Siemens technical reference and an Apter Power installation and commissioning guide.
      The technical reference preserves Siemens technical pages. The installation guide is prepared by Apter Power for planning and verification. Apply the complete Siemens and machine procedures during work.
      System context: In an S7-400 maintenance workflow, Flash media preserves a loadable application image separately from CPU execution memory.

      Configuration scope: Technical values apply to the complete 6ES7952-1KM00-0AA0 execution. The card current values use the exact MC 952 order-number entry in the S7-400 CPU specifications.
      Apply the approved SIMATIC S7-400 maintenance procedure and verify the following model-specific conditions before release.
      Match Flash technology

      It is a 5 V Flash EPROM MC 952 card. Its storage is nonvolatile and is distinct from a RAM card.

      Check card capacity

      The card capacity is 4 Mbytes. Confirm that the installed S7-400 CPU supports this card and the intended application image.

      Match the card design

      The offered order number identifies the long-design S7-400 card. Match the complete marking and host card slot rather than selecting by capacity alone.

      Budget operating current

      The MC 952 specification gives 40 mA typical and 90 mA maximum operating current at 5 V.

      Separate host backup needs

      The manufacturer technical table lists no backup current for this Flash card. Host CPU and application backup requirements still need separate consideration.

      Keep work memory distinct

      A load-memory card and CPU work memory perform different roles. The 4 Mbyte card capacity does not increase the integrated execution-memory partitions.

      Alternative Names

      Technical notes

      System relationship: In an S7-400 maintenance workflow, Flash media preserves a loadable application image separately from CPU execution memory.

      Configuration boundary: No. Equal capacity does not make RAM and Flash storage behavior identical. Match the storage technology and the host CPU procedure.

      Technical reference: Siemens 6ES7952-1KM00-0AA0 Data Sheet; S7-400 Automation System CPU Specifications, A5E00267840-03. Technical values apply to the complete 6ES7952-1KM00-0AA0 execution. The card current values use the exact MC 952 order-number entry in the S7-400 CPU specifications.

      FAQ View All FAQ

      • Which memory technology is used in 6ES7952-1KM00-0AA0?
        It is a 5 V Flash EPROM MC 952 card. Its storage is nonvolatile and is distinct from a RAM card.
      • How much application storage does 6ES7952-1KM00-0AA0 provide?
        The card capacity is 4 Mbytes. Confirm that the installed S7-400 CPU supports this card and the intended application image.
      • What does long design mean for 6ES7952-1KM00-0AA0 selection?
        The offered order number identifies the long-design S7-400 card. Match the complete marking and host card slot rather than selecting by capacity alone.
      • What current must be allowed for 6ES7952-1KM00-0AA0?
        The MC 952 specification gives 40 mA typical and 90 mA maximum operating current at 5 V.
      • Does 6ES7952-1KM00-0AA0 have a RAM backup-current requirement?
        The manufacturer technical table lists no backup current for this Flash card. Host CPU and application backup requirements still need separate consideration.
      • Will 6ES7952-1KM00-0AA0 increase the CPU work memory?
        A load-memory card and CPU work memory perform different roles. The 4 Mbyte card capacity does not increase the integrated execution-memory partitions.
      • What should be preserved before replacing 6ES7952-1KM00-0AA0?
        Keep the approved application archive, CPU configuration and intended startup image. Replacement hardware alone does not establish that the correct application is loaded.
      • Can a 4 MB RAM card be treated as identical to 6ES7952-1KM00-0AA0?
        No. Equal capacity does not make RAM and Flash storage behavior identical. Match the storage technology and the host CPU procedure.
