      Information

      Overview Manuals Common Applications Product Precautions
      Siemens 6ES7954-8LC04-0AA0 is a 4 MB SIMATIC flash memory card. It stores user programs, configuration, and device data for compatible SIMATIC and SINAMICS hardware.
      • Provides nonvolatile storage for a compatible SIMATIC CPU or SINAMICS device
      • Retains user program, configuration, and device data across power cycles
      • Supports project transfer using a programming device or approved card reader
      • Provides the removable storage medium required by selected controller workflows

      6ES7954-8LC04-0AA0 installs with compatible S7-1200 or S7-1500 CPU, SINAMICS device supporting the card, TIA Portal project, approved SD card reader in an engineered SIMATIC S7-1200 / S7-1500 and SINAMICS storage configuration.

      The commissioning workflow covers installed-hardware matching, controlled start-up and functional verification for this simatic 4 mb memory card.

      Important Notice: Confirm the complete 6ES7954-8LC04-0AA0 marking, installed-system configuration, field connections and controlled functional test before commissioning or replacement.

      2Back up the existing project and identify the destination CPU or drive.
      3Use ESD controls and handle the card only by its edges.
      4Do not format the card with an unsupported operating-system utility.
      5Confirm the project and firmware are approved for the target hardware.
      6Insert and remove the card only under the host procedure.
      7Observe startup diagnostics and confirm the intended program is active.
      8Retain a controlled copy of the final project and card identity.

      Technical notes

      Power down the host when required, protect the contacts from ESD and contamination, and verify the complete project, firmware compatibility, and CPU operating state after inserting 6ES7954-8LC04-0AA0.

      • What commissioning evidence should be retained for 6ES7954-8LC04-0AA0?
        Retain the full 6ES7954-8LC04-0AA0 identity, as-left wiring and settings, measured functional-test results, final diagnostics, and authorization to return the affected equipment to service.
      • Which installed hardware must be matched before fitting 6ES7954-8LC04-0AA0?
        Match the complete 6ES7954-8LC04-0AA0 marking to compatible S7-1200 or S7-1500 CPU and SINAMICS device supporting the card, then confirm the assigned SIMATIC S7-1200 / S7-1500 and SINAMICS storage position and approved system configuration.
      • How should the field connections for 6ES7954-8LC04-0AA0 be recorded before replacement?
        Record terminal or connector identity, polarity, shield, cable tag, channel assignment, and the as-found diagnostic state before disconnecting 6ES7954-8LC04-0AA0.
      • What isolation is required before installing 6ES7954-8LC04-0AA0?
        Place controller program storage in the approved maintenance state, isolate every applicable power, signal, and stored-energy source, and prove the work area safe.
      • Which configuration check is essential when commissioning 6ES7954-8LC04-0AA0?
        Restore only the approved model-specific channel, range, address, scale, or interface settings and compare them with the physical installation before enabling the process function.
      • How can an engineer function-test 6ES7954-8LC04-0AA0 after installation?
        Apply a controlled input, reference, or limited output appropriate to simatic 4 mb memory card, observe the system indication and diagnostics, and confirm the intended process response.
      • What should be checked if 6ES7954-8LC04-0AA0 reports an unstable or incorrect value?
