          PRODUCT DESCRIPTION

          6ES7954-8LL02-0AA0 256 MB SIMATIC Memory Card

          Siemens 6ES7954-8LL02-0AA0 is a 256 MB SIMATIC memory card for the documented S7-1X00 arrangement. It uses Flash EPROM storage and the 3.3 V card interface specified in the ordering description. The nonvolatile memory retains its programmed contents without treating the card as a battery-backed RAM module.

          The manufacturer specifies at least 200,000 write/delete cycles and a minimum retention period of ten years after the last programming operation. Storage capacity and electrical format are fixed by this article number. The supported controller, card function and project requirements must be taken from the applicable CPU instructions rather than inferred from the memory capacity alone.

          Information needed before ordering

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

          System integration Replacement check Manuals & support
          SYSTEM INTEGRATION

          Integrate 6ES7954-8LL02-0AA0 within SIMATIC S7-1X00 Memory Card

          Select the memory card only for a CPU and card function supported by the applicable SIMATIC S7-1X00 instructions. Match the 256 MB capacity and exact article number to the configured use. The 3.3 V figure describes the card interface and is not an instruction to connect an external field supply.
          Prepare or program the card through the supported SIMATIC procedure and preserve the required files and project structure. Account for the minimum 200,000-cycle endurance when an application repeatedly writes to the card; the card capacity alone does not establish unlimited write life.
          Follow the CPU-specific insertion, removal and startup instructions. Verify the expected card recognition and project behavior after installation and retain an approved backup of required data. Ten-year retention is measured after the last programming operation under the documented storage conditions.

          Features:

          • Memory capacity: 256 MB
          • Memory technology: Flash EPROM
          • SIMATIC S7-1X00 Memory Card
          Use 6ES7954-8LL02-0AA0 only within the documented SIMATIC S7-1X00 Memory Card arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace 6ES7954-8LL02-0AA0 within SIMATIC S7-1X00 Memory Card

          Record 6ES7954-8LL02-0AA0 and the installed card purpose before removal. A card with a similar physical outline or another capacity is not automatically an identical SIMATIC replacement.
          Back up the required project or stored files using the supported controller procedure and place the CPU in the prescribed state before exchanging the card. Protect contacts from electrostatic discharge and inspect the card slot without forcing the card.
          Restore the required card contents and verify CPU recognition, startup and the functions that depend on the memory card. Keep the original backup until the replacement has passed the approved controller checks.

          Features:

          • 6ES7954-8LL02-0AA0 complete order code
          • Minimum data retention: 10 years after last programming
          • Retain the documented SIMATIC S7-1X00 Memory Card connection arrangement
          Use 6ES7954-8LL02-0AA0 only within the documented SIMATIC S7-1X00 Memory Card arrangement and applicable installation instructions.

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about 6ES7954-8LL02-0AA0

          Direct answers about identity, compatibility, stock, warranty, payment and shipping.

          • What capacity must be retained when exchanging 6ES7954-8LL02-0AA0?

            6ES7954-8LL02-0AA0 identifies the 256 MB SIMATIC memory card. Match the complete code rather than selecting a visually similar card with another capacity.

          • Does the 3.3 V rating make 6ES7954-8LL02-0AA0 interchangeable with a consumer flash card?

            No. The 3.3 V rating of 6ES7954-8LL02-0AA0 does not establish format or controller compatibility. Use the SIMATIC card required by the installed CPU and firmware.

          • What write-cycle rating is stated for 6ES7954-8LL02-0AA0?

            6ES7954-8LL02-0AA0 lists a minimum 200000 write/delete cycles. Review the application's write behavior when investigating repeated storage wear.

          • What retention period is documented after programming 6ES7954-8LL02-0AA0?

            The specified minimum data retention of 6ES7954-8LL02-0AA0 is ten years after the last programming. That rating does not replace a maintained project backup.

          • What must be preserved before replacing an in-use 6ES7954-8LL02-0AA0?

            Preserve the installed controller project and required card contents before exchanging 6ES7954-8LL02-0AA0. A blank replacement card does not by itself recreate the running application.

          • Which controller information is needed to validate a 6ES7954-8LL02-0AA0 replacement?

            Check the CPU article number, firmware and intended card function against 6ES7954-8LL02-0AA0. Capacity alone is insufficient to confirm every controller/card combination.

          • Should a distributor describe 6ES7954-8LL02-0AA0 as preprogrammed without inspecting its contents?

            No. For 6ES7954-8LL02-0AA0, explicitly state whether the offer is for blank hardware or customer-requested contents. Do not imply that a project or license is included.

          • What helps purchasing avoid the wrong-capacity SIMATIC card when ordering 6ES7954-8LL02-0AA0?

            Put the full 6ES7954-8LL02-0AA0 code and 256 MB capacity on the order, together with the CPU identity. List any required project transfer as separate scope.
