Establish device context
Confirm the approved endpoint, active interface, device identity and live MMS model before interpreting results.
Controlled commissioning · live troubleshooting · attributable evidence
IEC 61850 commissioning with clear live-system evidence.
Use ARSAS to inspect current values, quality, timestamps, reporting state, GOOSE behavior, command completion, fault-record access and per-IED diagnostics while commissioning activities are performed under an approved procedure.
Live valuesDevice, quality, timestamp and acquisition source
SOEBounded semantic events with originating IED context
ControlDirect and SBO outcomes with completion evidence
DiagnosticsAssociation, service, report and frame visibility
Suggested workflow
Investigate the live path before changing configuration.
Commissioning pressure can encourage premature changes. Start by preserving the evidence already available from the IED and network.
Observe values and events
Review selected values, quality, process timestamps, reason-for-inclusion and semantic event history.
Inspect reporting and GOOSE
Check RCB state, DataSet coverage, stream identity, sequence counters, retransmission and payload evidence.
Execute only approved operations
Use typed Direct or SBO workflows only when the procedure, role and plant condition permit active control.
Retain negative evidence
Unsupported services, rejected writes, report gaps, timeouts and command failures remain visible for root-cause analysis.
Event evidence with device context
Separate continuous values from meaningful changes while retaining timestamp, quality, source and originating-device attribution.
Controlled live-system investigation.
- Reporting and quality troubleshooting
- GOOSE sequence and subscription checks
- Control completion and feedback review
- Fault-record retrieval after events
- Multi-IED communication diagnostics
Commissioning authority remains external.
ARSAS does not grant switching permission, determine plant safety, replace protection testing, approve settings or override site procedures, cybersecurity controls and independent verification.

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.
