ARSVIN is a GPL-3.0-or-later IEC 61850 Sampled Values engineering suite for Windows. It includes an SCL-driven Publisher and a live and PCAP Subscriber companion.

Does ARSVIN require Npcap?

Npcap is required for live raw Ethernet capture and transmission. Offline configuration, dry-run, COMTRADE, and PCAP workflows can be used without live network access.

Is ARSVIN a certified IEC 61850 test set?

No. ARSVIN is engineering software for authorized laboratory and commissioning-support workflows. It is not calibrated deterministic real-time equipment, a certified merging unit, or a formal conformance platform.

Can ARSVIN prove that an IED consumed an SV stream?

No. Sampled Values multicast has no application-layer acknowledgement. ARSVIN records what the Publisher generated and what the selected computer or adapter received, but it does not prove IED consumption or process action.

GPL-3.0-or-later · Windows x64 · Authorized engineering workflows

Generate Sampled Values. Inspect what arrives. Preserve the evidence.

ARSVIN combines an SCL-driven SV Publisher with ArSubsv Subscriber for COMTRADE replay, live and PCAP capture, decoded values, waveform, phasor, RMS, continuity diagnostics, profile evidence, and engineering reports.

ArSubsv live analysis interface showing channel values, phasor, voltage waveform, and current waveform — Actual Subscriber workspace — channels, phasor, voltage, and current analysis.

One repository, two focused applications

Transmitter evidence and receiver evidence stay separate.

Publisher and Subscriber have distinct responsibilities so each workflow remains understandable, testable, and explicit about what it proves.

ARSVIN Publisher

Build repeatable streams from SCL, manual values, scenarios, waveform shaping, or COMTRADE records.

SCL and SCD stream setup
Dataset-aware payload generation
Multi-ASDU packing and timing health
Generated PCAP and evidence report

ArSubsv Subscriber

Discover and decode live or recorded traffic, bind streams to SCL, and inspect receiver-side behavior.

Live Npcap capture and PCAP import
Stream and smpCnt health
Waveform, phasor, and RMS
Receiver evidence report

Actual Windows interfaces

Review the workflow before sending a frame.

ARSVIN Publisher SV setup with SCL stream selection, source modes, network fields, and manual output controls — Publisher setup — stream, adapter, network, source, and output configuration.

ArSubsv live analysis with channel table, phasor plot, voltage waveform, and current waveform — Subscriber analysis — decoded channels, phasor, voltage, and current.

ArSubsv stream monitor with discovered Sampled Values streams, voltage and current waveforms, phasor view, and RMS values — Stream monitor — discovered traffic, waveform, phasor, RMS, and continuity inspection.

Engineering workflow

Trace configuration, observed traffic, and evidence without overclaiming.

Configure from SCL

Reuse APPID, destination MAC, VLAN, svID, dataset, confRev, sample rate, and packing.

Generate scenarios

Use manual values, ramps, faults, waveform shaping, sequence components, or COMTRADE replay.

Inspect stream health

Expose timing, continuity, counters, payload layout, decoded values, and configuration differences.

Preserve evidence

Export PCAP and Markdown reports for independent review and repeatable laboratory records.

Search-indexable engineering documentation

Understand the boundary before enabling live Ethernet.

Documentation is published as dedicated HTML pages with canonical metadata, structured data, navigation, and sitemap discovery.

Quick Start

Begin with a dry run, synthetic sample, PCAP file, or authorized isolated link.

SV Profile Support

Review implemented behavior, generic payload support, and explicit limitations.

Subscriber Verification

Inspect continuity, decoded values, waveform, phasor, RMS, and receiver evidence.

Licensing

Understand GPL community rights, historical revisions, and the separate commercial path.

SETUP

ARSVIN-Suite-Setup-win-x64.exe

Publisher, Subscriber, documentation, legal notices, shortcuts, and uninstaller.

ZIP

ARSVIN-win-x64-portable.zip

Portable suite folder with both applications and required notices.

ARSVIN-Publisher-win-x64.exe

Self-contained single-file Publisher.

ArSubsv-Subscriber-win-x64.exe

Self-contained single-file Subscriber.

Releases also provide ARSVIN-SBOM.cdx.json and SHA256SUMS.txt. Npcap is installed separately and is not silently bundled.

Operational boundary

Software checks do not establish site authorization or process safety.

Use live capture and transmission only under an approved test plan and network boundary. ARSVIN does not establish isolation, switching authority, functional safety, cybersecurity approval, calibrated measurement, deterministic timing, or IED consumption.
