Evidence ledger

Facts, inferences, and unknowns are kept separate.

Facts

  • Siemens identifies 6AU1400-2PA22-0AA0 as a 1 GB CompactFlash card for SIMOTION D4x5-2 controllers.

    Confidence: high

  • The SIMOTION manual states that this card carries the kernel and SINAMICS firmware, supports firmware updates and data backup, and is not interchangeable with D4x5 cards.

    Confidence: high

Inferences

  • 6AU1400-2PA22-0AA0 occupies the documented system position described in its function and interfaces.

    Confidence: high

    Rationale: The exact product identity and documented interfaces support this concrete system position.

Unknowns

  • Unknown: the installed project or program, field wiring, firmware, cabinet fit and physical condition of a particular 6AU1400-2PA22-0AA0 unit.

    Confidence: low

    Missing evidence: The captured sources do not establish the installed project, wiring, firmware, cabinet fit or physical condition of a particular unit.
