ARIEC61850 Engine Compatibility

ARSAS 1.6.19 is an application-only repository. It compiles against the separately maintained ARIEC61850 source projects and uses engine-owned contracts for MMS, reporting, GOOSE, Sampled Values, file services, control, SCL workspace services, discovery, and diagnostics.

Immutable integration baseline

The reviewed engine revision used by CI and packaging is stored in:

engines/ARIEC61850.lock.json

Current baseline:

repository: masarray/ARIEC61850
ref: main
commit: 0f8453182957900bc6d91287fb8177c8d9762188
source PR: #45

CI fetches the exact 40-character commit and checks it out detached. A temporary feature branch is not part of the reproducible build identity.

Required engine areas

The build verifies the presence of application-consumed contracts for:

  • Smart Control and CommandTermination;
  • SCL workspace comparison and schema-aware export;
  • typed DataSet binding and stable member order;
  • GOOSE parsing and process-bus supervision;
  • Sampled Values parsing, generic payload inspection, timebase resolution, sample-counter tracking, and Npcap capture;
  • file-service, discovery, reporting, and diagnostic services referenced by the application project.

If a required contract is missing, CI and local builds fail explicitly rather than silently degrading the operator workflow.

Recommended sibling layout

D:\Git\
├─ ARIEC61850\
│  └─ src\
│     ├─ AR.Iec61850\AR.Iec61850.csproj
│     └─ AR.Iec61850.Transports.Npcap\AR.Iec61850.Transports.Npcap.csproj
└─ arsas\
   ├─ ArIED61850Tester.csproj
   └─ tests\ARSAS.Tests\ARSAS.Tests.csproj

Build and test with the default sibling references:

dotnet restore .\ArIED61850Tester.sln
dotnet build .\ArIED61850Tester.sln -c Release --no-restore
dotnet test .\tests\ARSAS.Tests\ARSAS.Tests.csproj -c Release --no-build --no-restore

Another reviewed engine checkout may be selected with the existing MSBuild properties or environment variables, but release evidence must record the exact commit and must not imply compatibility with an unreviewed moving branch.

Source and package boundary

ARSAS does not overwrite or vendor the ARIEC61850 source repository. A published Windows package may contain compiled engine assemblies as part of the combined GPL community application, while reusable protocol implementation remains owned and tested in ARIEC61850.

Control operations intentionally have no generic MMS-write fallback. The native engine must provide a usable control descriptor and sequence contract before ARSAS enables command dispatch.

Claim boundary

A successful build and regression suite proves compatibility with the pinned software revision. It does not establish formal IEC 61850 conformance, calibrated measurement accuracy, universal device interoperability, switching authority, cybersecurity approval, or functional-safety certification.
