Caution

ARSVIN can capture and transmit raw Ethernet traffic. Use live features only on an isolated laboratory network, an authorized point-to-point test link, or another network for which you have explicit authority. ARSVIN is not a certified relay test set, calibrated merging unit, deterministic real-time platform, functional-safety system, production process-bus monitor, or IEC 61850 conformance certificate.

Engineering purpose

ARSVIN is a focused Windows suite for practical IEC 61850 Sampled Values work. It combines:

• ARSVIN Publisher for SCL-assisted stream configuration, manual and scenario-based generation, waveform shaping, COMTRADE replay, timing-health visibility, and transmitter-side evidence; and
• ArSubsv Subscriber for live or PCAP stream discovery, decoding, SCL-assisted binding, waveform, phasor, RMS, continuity diagnostics, and receiver-side evidence.

Publisher evidence shows what the selected computer generated. Subscriber evidence shows what the selected computer and network adapter received and decoded. Neither proves that another IED consumed, trusted, or acted on a multicast stream.

Core workflows

Publisher

Open or create configuration
        ↓
Review SCL-derived stream and dataset settings

        ↓
Transmit only on an authorized test link
        ↓
Export PCAP, timing health, and Markdown evidence

Subscriber

Choose live adapter or PCAP file
        ↓
Discover Sampled Values streams
        ↓
Optionally bind observed traffic to SCL expectations
        ↓
Inspect counters, timing, decoded values, waveform, phasor, and RMS
        ↓
Record mismatches and receiver-side evidence

Current capabilities

ARSVIN Publisher

• SCL/SCD stream setup for APPID, destination MAC, VLAN, svID, dataset, confRev, smpRate, smpMod, and nofASDU.
• Laboratory-oriented IEC 61850-9-2LE-style 4I+4V publishing.
• Multi-ASDU packing with nofASDU=1/2/4/8.
• Up to three independent publisher slots.
• Manual values, ramps, state sequences, per-phase scenarios, waveform shaping, and COMTRADE replay.
• Intentional quality-bit modes for controlled behavior checks.
• Target/actual frame rate, jitter, late-frame, missed-schedule, and send-duration evidence.
• Generated PCAP and Markdown reports.

ArSubsv Subscriber

• Live capture through Npcap and offline classic-PCAP import.
• Stream discovery and SCL-assisted binding.
• APPID, VLAN, svID, confRev, nofASDU, sample-rate, and payload-layout checks.
• smpCnt continuity and stream-health diagnostics.
• Decoded instantaneous values, oscilloscope waveform, phasor, and RMS views.
• Receiver-side Markdown evidence reports.
• Shared-engine foundation for evidence-aware profile classification and configuration-versus-wire comparison.

Evidence-aware profile foundation

The engine separates:

Observed wire facts
Configured SCL expectations
Evidence-backed profile definitions
Explainable confidence
Strict or compatible mismatch findings

Sparse evidence does not produce a Confirmed profile result. Unknown or conflicting traffic remains visible. Named-profile support is added only when requirements and test evidence have documented provenance.

See SV Profile Infrastructure, Profile Detection Output Contract, and SV Standards and Evidence Research Gate.

Supported scope and claim boundary

Area	Current status	Boundary
IEC 61850 Sampled Values APDU	Publisher and Subscriber implementation for engineering and laboratory use	Not certified conformance testing.
IEC 61850-9-2LE-style 4I+4V	Implemented laboratory workflow	Formal profile verification and broader device evidence remain pending.
Generic SCL-driven Layer-2 SV	Dataset-aware engine foundation	Unknown layouts remain visible and unsupported elements are diagnosed.
Evidence-aware profile detection	Engine infrastructure implemented	Named-profile definitions require verified source and device evidence.
nofASDU	UI workflows emphasize 1, 2, 4, and 8	Software and PC timing remain non-deterministic.
COMTRADE	ASCII, BINARY, BINARY32, and FLOAT32 analog replay	Scaling and channel mapping must be reviewed before live transmission.
PTP / smpSynch	Compatibility-oriented laboratory behavior	Not an IEC 61850-9-3 certified clock.
Windows timing	Best-effort scheduling with visible health metrics	Not deterministic real-time execution.
IED subscription proof	Not provided	Sampled Values multicast has no application-layer acknowledgement.

Evidence language in this repository distinguishes implemented behavior, deterministic tests, simulator or loopback evidence, laboratory observations, and features that remain provisional or unverified.

Release downloads

Every tagged release builds Windows x64 artifacts with stable filenames:

Artifact	Purpose
ARSVIN-Publisher-win-x64.exe	Self-contained single-file Publisher.
ArSubsv-Subscriber-win-x64.exe	Self-contained single-file Subscriber.
ARSVIN-Suite-Setup-win-x64.exe	Installer containing both applications, documentation, notices, and uninstaller.
ARSVIN-win-x64-portable.zip	Portable suite with both applications and required legal/documentation files.
ARSVIN-SBOM.cdx.json	CycloneDX 1.5 software bill of materials.
SHA256SUMS.txt	SHA-256 checksums for release verification.

Tagged releases publish GitHub artifact attestations. Example verification:

gh attestation verify .\ARSVIN-Suite-Setup-win-x64.exe --repo masarray/arsvin

The binaries are currently unsigned, so Windows SmartScreen may display an unknown-publisher warning. Npcap is not silently installed or bundled; install it separately from its official source when live capture or transmission is required.

Quick start

Installer

1. Download ARSVIN-Suite-Setup-win-x64.exe from the latest release.
2. Install the suite.
3. Install Npcap separately for live Ethernet workflows.
4. Open ARSVIN Publisher or ArSubsv Subscriber.
5. Begin with a dry run, synthetic sample, PCAP import, or authorized isolated test link.

Portable

1. Download the portable Publisher, Subscriber, or suite ZIP.
2. Run the selected application directly.
3. Use elevated privileges only when required by the selected Npcap and network configuration.

See Quick Start, Safety Boundaries, and Known Limitations.

System requirements

For users:

• Windows 10 or Windows 11, x64.
• Npcap for live capture or transmission.
• Administrator permission only when required by local driver or adapter configuration.
• An independent packet dissector or process-bus analyzer is recommended for verification.

For developers:

• .NET 8 SDK, feature band 8.0.4xx.
• PowerShell 7+ recommended.
• Visual Studio 2022, JetBrains Rider, or VS Code with C# tooling.
• Inno Setup 6.7.1 when reproducing the automated installer build.

Build from source

git clone https://github.com/masarray/arsvin.git
cd arsvin
.\build.ps1

The resolved dependency graph is committed through packages.lock.json, and validated automation restores in locked mode.

Build release artifacts except the installer:

.\scripts\publish-release.ps1 -Version 0.4.0

Run tests with both coverage gates:

.\scripts\test-with-coverage.ps1 -MinimumWholeEngineLineCoverage 14.25 -MinimumLineCoverage 72.5

The current baseline contains 88 deterministic tests. Whole-engine coverage is 14.61% across 16,582 instrumented lines, while protocol-core coverage is 72.76% across 2,390 lines. CI enforces floors of 14.25% and 72.5% respectively; these values are engineering regression evidence, not formal protocol conformance evidence.
