Ordered Digital-Indication Evidence
Import approved SDI points, bind them to one IED, require OFF → ON → OFF evidence, and export Excel, native PDF or a verified .arsas continuation project.
Current product scope · explicit maturity · real application evidence
IEC 61850 capabilities built around engineering outcomes—not isolated protocol screens.
ARSAS starts from an approved endpoint, SCL source or IO List, retains identity and live evidence, and connects FAT test plans, SCL generation, monitoring, reporting, process-bus traffic, fault records, control outcomes and diagnostics to the correct IED context.
IO FAT available on mainStrict SDI import, ordered edges, Excel/PDF and portable .arsas
IP-to-SCL availableComplete discovery to Edition 2 IID or Edition 1 ICD
Multi-IED availableIndependent sessions and unified evidence across devices
Truthful boundaryMainline features, stable release scope and roadmap remain distinct
Development versus stable release
IO List FAT is documented from the current 1.6.19 mainline.
The latest published stable installer remains 1.6.18 until a separately validated and tagged release is produced. Check Release Notes before assuming the stable download contains a current-main capability.
Dedicated product pages
Choose the engineering result you need.
Each page explains the workflow, evidence available in ARSAS, current limitations and the relationship between configured intent and live device behavior.
Live Discovery to IID or ICD
Discover the complete typed model from an approved IED IP address and generate a schema-aware Edition 2 IID or Edition 1 ICD with companion evidence.
Generic Single-IED Output
Open SCD, CID, ICD, IID or SSD context, preserve the source and create bounded single-IED output with structured interoperability findings.
IEC 61850 MMS Client
Connect by approved IP address, discover the live hierarchy and inspect searchable values, quality, timestamps, DataSets, RCBs and controls.
Smart Reporting
Prefer verified BRCB or URCB coverage, evaluate exact DataSet membership, recover permitted gaps and keep visible fallback.
GOOSE Analyzer
Inspect APPID, VLAN, destination MAC, goCBRef, stNum, sqNum, TAL, retransmission, flags and ordered payload evidence.
File Transfer and COMTRADE
Probe MMS file services, browse bounded directories and retrieve complete, partial or vendor-specific disturbance-record files with exact diagnostics.
Bounded CID Export
Audit live RCB availability, preserve exact names and verified DataSet members, then export one intended Edition 1 or Edition 2 CID baseline.
Smart Control
Read ctlModel, resolve live command descriptors and execute supported Direct or Select-Before-Operate sequences with visible outcomes.
Multi-IED Monitoring
Keep associations, values, events, files, controls and diagnostics isolated per device while reviewing project-wide evidence.
FAT, SAT, commissioning and integration
Apply the available capabilities to the project stage you are preparing for, with focused workflows and explicit evidence boundaries.
Sampled Values
Per-IED SMV entry points and a viewer workflow are available for controlled evaluation. Production maturity still requires deeper decoding, binding, scaling and sustained-performance validation.
Verified stable release · ARSAS 1.6.33
Download the release-grade IEC 61850 workstation for Windows.
The current stable build includes Rev.3 IO List FAT import, an executive AS TESTED evidence report, a loaded Engineering/FAT workspace session, and direct receive-only GOOSE plus bounded SMV capture from each IED card.
Use the installer for a normal workstation, choose the portable single EXE for an approved no-install deployment, and verify the published SHA-256 before use.
