6AV6371-1CF07-5AX0 SIMATIC WinCC/Redundancy V7.5

6AV6371-1CF07-5AX0 is a documented WinCC Redundancy option for the stated WinCC role.

System role

Rebuilt from individual evidence

Evidence and limits

6AV6371-1CF07-5AX0 is documented as SIMATIC WinCC/Redundancy V7.5. Monitors two WinCC installations so the documented redundant option can support continuity after a server or station failure.

Between two interfaced WinCC single-user systems or process-data servers operating as a redundant pair. The surviving WinCC installation takes over the system role when its pair is unavailable, subject to project checks.

Unknown: installed WinCC version, project configuration, license entitlement, deployment compatibility, current availability, support status, and individual license or media status.

This section explains what the product does and where it acts in the surrounding system.

Function
Monitors two WinCC installations so the documented redundant option can support continuity after a server or station failure.
System position
Between two interfaced WinCC single-user systems or process-data servers operating as a redundant pair.
Upstream / inputs
The two WinCC installations exchange their runtime and archive state.
Downstream / outputs

Evidence ledger

Facts, inferences, and unknowns are kept separate.

Facts

  • The captured source identifies 6AV6371-1CF07-5AX0 as SIMATIC WinCC/Redundancy V7.5.

    Confidence: medium

  • The fetched Siemens copyright data sheet copy identifies the exact article as SIMATIC WinCC/Redundancy V7.5, an option for WinCC V7.5, single license for two installations; the Siemens catalog copy documents mutual monitoring and takeover behavior.

    Confidence: high

  • The captured product evidence describes 6AV6371-1CF07-5AX0 as a licensed WinCC Redundancy software option; the exact entitlement is limited to the scope stated in the source.

    Confidence: medium

Inferences

  • Inferred system position: Between two interfaced WinCC single-user systems or process-data servers operating as a redundant pair.

    Confidence: medium

    Rationale: The exact-reference product description and the fetched WinCC system documentation identify the named option and its place in the documented data or licensing path.

Unknowns

  • Unknown: compatibility with the installed WinCC version, project configuration, license entitlement, and deployment environment.

    Confidence: low

    Missing evidence: No installation-specific WinCC version, project, license entitlement, or deployment configuration was captured.

  • Unknown: current commercial availability, support status, and validity of any individual license key or media.

    Confidence: low

    Missing evidence: The individual research did not establish current stock, support status, or validity of a particular license key or media.
