          PRODUCT DESCRIPTION

          6ES7951-1AJ00-0AA0 512 kB Short RAM Memory Card

          Siemens 6ES7951-1AJ00-0AA0 is a 512 kB RAM memory card in the short design for the documented SIMATIC S7-300 platform. It provides the specified RAM memory-card capacity for a controller that supports this card type. The complete order code distinguishes it from Flash EPROM cards and later Micro Memory Card formats.

          The manufacturer identifies RAM as the storage technology and 512 kB as the capacity. Data retention and transfer depend on the host CPU memory and backup arrangement; this card must not be described as nonvolatile Flash storage. A compatible CPU and its memory-management instructions determine how the card participates in application loading, backup and replacement.

          SYSTEM & REPLACEMENT CHECK

          Information needed before ordering

          Three direct checks to secure your system integration and minimize ordering risks.

          Information

          System integration Replacement check Manuals & support
          SYSTEM INTEGRATION

          Integrate 6ES7951-1AJ00-0AA0 within SIMATIC S7-300

          Verify that the installed S7-300 CPU supports the short RAM memory-card format and 512 kB capacity. Check the CPU order code and its memory instructions before insertion. This RAM card is not mechanically or functionally equivalent to a SIMATIC Micro Memory Card.
          Manage the application through the host CPU programming procedure and distinguish RAM card storage from the CPU work-memory area. The card capacity does not automatically increase processor work memory. Retention depends on the CPU backup arrangement rather than Flash behavior.
          Keep the card contacts clean and use the manufacturer handling and ESD precautions. Retain an independent project backup and document the card contents before service. Validate the intended load and restart behavior on the supported CPU configuration.

          Features:

          • Memory technology: RAM
          • Memory capacity: 512 kB
          • SIMATIC S7-300
          Use 6ES7951-1AJ00-0AA0 only within the documented SIMATIC S7-300 arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace 6ES7951-1AJ00-0AA0 within SIMATIC S7-300

          Record 6ES7951-1AJ00-0AA0, the connected CPU, card contents and backup state before exchange. Preserve the 512 kB RAM identity and short design. A Flash EPROM card with similar capacity should not be treated as the same storage technology.
          Back up the project and follow the host CPU procedure for removing or inserting memory hardware. Prevent loss of the only available application copy, and use ESD protection while handling the contacts. Check the CPU backup arrangement before relying on retained RAM data.
          Load or restore the supported application using the CPU procedure and verify the resulting memory status. Confirm the expected program and retained values before normal startup. Keep the validated project copy separate from the replacement card.

          Features:

          • 6ES7951-1AJ00-0AA0 complete order code
          • Mechanical format: Short memory-card design
          • Retain the documented SIMATIC S7-300 connection arrangement
          Use 6ES7951-1AJ00-0AA0 only within the documented SIMATIC S7-300 arrangement and applicable installation instructions.
