Built to make practical IEC 61850 work clearer and faster.

ARSAS is an independent open-source Windows engineering workstation created to reduce repetitive setup during IEC 61850 laboratory work, FAT, SAT, commissioning, troubleshooting and multi-vendor integration.

Why ARSAS exists

Useful testing should begin from the evidence available in the IED.

IEC 61850 workflows can lose significant time before the first useful value appears: preparing engineering files, inspecting DataSets, finding usable Report Control Blocks, mapping signals across tools and diagnosing why communication works while reporting remains silent.

ARSAS brings live MMS discovery, reporting visibility, GOOSE supervision, file transfer, SCL context, control evidence and diagnostics into one focused workspace.

Project principle

Complement engineering tools—not hide engineering reality.

ARSAS does not claim universal interoperability, conformance certification, switching authority or replacement of approved vendor engineering systems. It is designed to expose live behavior, preserve negative evidence and help engineers make better-informed decisions.

Capability status, preview scope, limitations and safety boundaries remain explicit throughout the product website.

Author and maintainer

Ari Sulistiono

Ari Sulistiono is a substation automation engineer focused on protection and control, IEC 61850 communication, testing, commissioning, troubleshooting and practical engineering productivity.

ARSAS turns recurring field and integration problems into a reusable public engineering tool while keeping customer, employer, credential, relay-setting and substation data outside the repository.

Engineering commitments

Useful, transparent and bounded.

Professional open-source engineering requires more than feature claims. ARSAS keeps current scope, uncertainty and safety responsibilities visible.

Real application evidence

Product pages use current application screenshots and working workflows instead of conceptual marketing mockups.

Explicit maturity labels

Available, preview, planned and research work are kept separate to avoid overstating readiness.

Negative outcomes remain visible

Association failures, unsupported services, report gaps, file errors and negative command completion are engineering evidence.

Download Center

The Download Center provides the stable installer, portable ZIP, checksums, system requirements and release guidance.

Source transparency

The public repository remains available for developers, contributors and technical audit.

Data discipline

Customer, credential, relay-setting and substation data must not be used as public examples or committed to the project.

Verified stable release

Download ARSAS 1.6.17 for Windows.

Use the installer for a normal workstation, choose the portable ZIP for a controlled folder deployment, and verify the published SHA-256 before use.
