ARSVIN is an Apache-2.0 IEC 61850 Sampled Values engineering suite for Windows. It includes an SCL-driven Publisher and a live and PCAP Subscriber analysis companion.

Is ARSVIN a certified IEC 61850 test set?

No. ARSVIN is laboratory-oriented engineering software. It is not calibrated, deterministic real-time equipment, a certified merging unit, or an IEC 61850 conformance test platform.

Can ARSVIN prove that a protection IED subscribed to an SV stream?

No. IEC 61850 Sampled Values is multicast and has no application-layer acknowledgement. ARSVIN can show what the Publisher generated and what the selected PC or NIC received, but not prove IED consumption.

Sampled Values publishing and analysis, without a black box.

ARSVIN combines an SCL-driven SV Publisher with a focused Subscriber companion for live capture, PCAP replay, decoded values, waveform, phasor, RMS, stream health, profile evidence, and engineering reports.

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

One repository, two focused tools

Generate the stream. Inspect what arrives.

Publisher and Subscriber remain separate applications so each workflow stays understandable, testable, and honest about what it proves.

ARSVIN Publisher

Build repeatable SV streams from SCL, manual values, per-phase scenarios, waveform shaping, or COMTRADE records.

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

ArSubsv Subscriber

Discover and decode live or recorded SV 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

These are captures from the Publisher and Subscriber applications, not generic product mockups.

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

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

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

Engineering workflow

Useful visibility from configuration to evidence.

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, troubleshooting, and repeatable laboratory records.

Search-indexable engineering documentation

Understand the workflow before sending a frame.

Repository guides are published as dedicated HTML pages with canonical metadata, structured data, navigation, and sitemap discovery.

Quick Start

Install the suite and begin with an authorized dry run, PCAP, or isolated link.

SV Profile Support

Review current profile support, generic payload behavior, and explicit technical boundaries.

Subscriber Verification

Inspect live or recorded streams, continuity, decoded values, waveform, phasor, RMS, and evidence.

Safety Boundaries

Understand laboratory assumptions, evidence limits, and responsible live-network use.

Current binaries are unsigned and may trigger a Windows SmartScreen warning. Npcap is not bundled. Verify downloads with SHA256SUMS.txt and review the release SBOM.

Explicit boundaries

Designed for controlled laboratory use.

ARSVIN can transmit and capture raw Ethernet frames. Use isolated networks, point-to-point links, or networks where you have explicit authorization.

It is not a certified protection test set, calibrated merging unit, deterministic real-time platform, production process-bus monitor, or IEC 61850 conformance tool.

FAQ

Clear answers before live traffic.

What does the Subscriber prove?

It proves that the selected PC or NIC received and decoded the stream. It does not prove that a relay or other IED consumed the multicast traffic.

Does ARSVIN require Npcap?

Npcap is required for live raw Ethernet capture and transmission. PCAP import, documentation, configuration, and dry-run workflows do not require live network access.

Is the installer code-signed?

Not currently. Release assets include SHA-256 checksums, an SBOM, and repository workflow provenance, but Windows may still show an unknown-publisher warning.

Can ARSVIN replace a calibrated test set or certified analyzer?

No. ARSVIN is transparent engineering software for controlled laboratory workflows, education, development, and troubleshooting support.
