IEC 61850 FAT testing
Validate live models, selected signals, reports, GOOSE, control outcomes and disturbance-record access before shipment.
FAT · SAT · commissioning · multi-vendor integration
IEC 61850 workflows built around project execution.
ARSAS connects live MMS discovery, reporting, GOOSE, SCL context, control, file transfer and diagnostics to the same IED session so engineering teams can move from endpoint access to attributable evidence with less fragmented setup.
Project workflows
Choose the stage you are preparing for.
Each solution page focuses on the evidence, risks and practical sequence that matter at that project stage.
IEC 61850 SAT testing
Reconfirm endpoint access, reporting, station-bus behavior and system integration after installation at site.
IEC 61850 commissioning
Investigate live behavior, sequence evidence, communication quality and command completion during controlled commissioning.
Multi-vendor interoperability
Compare configured SCL intent with observed IED behavior and isolate reporting, GOOSE and model mismatches.
One workspace, independent IED sessions
Keep association, model, selected signals, reporting state, files, control context and diagnostics attributable to the originating device throughout the project workflow.
Start from live evidence.
Use the approved endpoint and available SCL context to discover what the IED exposes, then validate the signals and services required by the test procedure.
ARSAS supports the test process.
It does not replace approved procedures, calibrated test equipment, protection-setting verification, switching authority, witness acceptance or vendor engineering responsibility.
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.
