ARSAS 1.6.18

ARSAS 1.6.18

ARSAS 1.6.18 strengthens field workflows for IEC 61850 fault-record download, physical IED identity, and selected-RCB CID export while keeping the user interface compact and evidence-driven.

What's new

• Fault-record transfer now supports adaptive remote paths, large segmented COTP responses, automatic file scanning, overwrite-safe redownloads, and detailed failure diagnostics.
• Physical IED identity is resolved independently from complete MMS Logical Device domain names, preventing incorrect IEDName export.
• Selected-RCB CID export preserves the exact live MMS RCB name and prevents invalid duplicate instance suffixes such as A_BRCB_120101.
• The RCB export and fault-record windows use cleaner compact layouts with clearer availability, downloaded-state, and selection feedback.

Reliability improvements

• COMTRADE companion files and vendor package-style records can be discovered and downloaded through the same guarded file-service workflow.
• File transfer diagnostics capture the failing MMS stage, invoke ID, FRSM, session state, and request/response evidence.
• Downloaded fault records remain selectable for intentional overwrite instead of being permanently disabled.
• Exact live RCB-name regressions are protected by engine tests and application release gates.
• Installer, portable ZIP, and combined SHA-256 checksums are published together after build and silent install/uninstall smoke tests.

Known limitations

• Windows x64 is the only packaged desktop platform in the current stable release.
• The public binaries are not Authenticode code-signed; Windows SmartScreen may show an unrecognized-publisher warning.
• Raw-Ethernet GOOSE and Sampled Values workflows require Npcap, an approved adapter and suitable capture permissions.
• Relay file-service directories and COMTRADE companion sets vary by vendor; a successful transfer does not prove record completeness or scaling correctness.
• Active control and report-configuration writes still require approved procedures, plant authority and independent verification.
• ARSAS is an engineering evidence tool and does not provide IEC 61850 conformance certification or replace calibrated protection testing.

Code-signing status

Not Authenticode-signed. The current public Windows installer and portable binaries do not carry a commercial Authenticode publisher signature. Verify the published SHA-256 value before use. SmartScreen warnings are therefore possible and are not hidden from users.
