Download ARSAS 1.6.17 with verifiable release evidence.

Choose the installer for a normal engineering workstation or the portable ZIP for a controlled folder-based deployment. Both packages are published from verified CI artifacts and have public SHA-256 values.

Folder-based

Portable ZIP

Best for approved test laptops, temporary evaluation or environments where installation is not preferred. Extract to a writable local folder and update by replacing the package.

Installer vs Portable

Choose based on deployment—not on feature availability.

The IEC 61850 application scope is the same. The difference is how Windows stores, launches, removes and updates the package.

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.

Status: unsigned
Known limitations

Review the current boundaries.

  • 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.
Issue reporting

Report package or runtime problems with evidence.

Include version 1.6.17, installer or portable package, Windows version, exact error, screenshot or log, and whether the published checksum matched.

System scope

Prepared for approved Windows engineering workstations.

  • Windows 10 or Windows 11, x64
  • Self-contained .NET application package
  • Npcap required for raw-Ethernet GOOSE and Sampled Values
  • Approved laboratory, FAT, SAT or commissioning network
  • Independent authority required for active controls and writes
