ARSVIN is an IEC 61850 Sampled Values engineering suite with a shared engine, ARSVIN Publisher, and ArSubsv Subscriber.
- Observable and evidence-backed Sampled Values behavior.
- Explicit operational guardrails for live capture and transmission.
- Clear separation between Publisher, Subscriber, and shared engine responsibilities.
- Repeatable SCL, COMTRADE, PCAP, scenario, test, and release workflows.
- Accurate public documentation, licensing, provenance, and claim boundaries.
- Performance and usability improvements that preserve engineering evidence.
Protocol parsing, stream generation, SCL semantics, profile observations, comparison logic, capture, and transport behavior belong in ARSVIN.Engine. WPF applications should consume typed engine contracts rather than reimplement protocol rules.
External software may be used only as a lawfully licensed black-box interoperability endpoint. Do not use unrelated source, API composition, examples, tests, internal structure, documentation wording, UI composition, screenshots, icons, reports, or extracted resources as implementation design material.
Use synthetic or contributor-owned fixtures. Real SCL, COMTRADE, PCAP, screenshots, and diagnostics require documented authority to share and sanitization.
Do not claim formal IEC 61850 conformance, universal interoperability, calibrated measurement, deterministic real-time execution, functional safety, cybersecurity certification, switching authority, or proof that another IED consumed a multicast stream.
State the evidence source and use scoped terms such as implemented, tested, observed, provisional, unsupported, or not yet verified.
