task-galaxy-e2e branch — non-FOCAS work-in-progress snapshot
Catch-all commit for pending work on the task-galaxy-e2e branch that
wasn't part of the FOCAS migration. Grouping by topic so future per-topic
commits can be cherry-picked if needed.
TwinCAT
- src/.../Driver.TwinCAT/AdsTwinCATClient.cs + TwinCATDriverFactoryExtensions.cs:
factory-registration extensions + ADS client refinements.
- src/.../Driver.TwinCAT.Cli/Commands/BrowseCommand.cs: new browse command
for the TwinCAT test-client CLI.
- tests/.../Driver.TwinCAT.IntegrationTests/TwinCAT3SmokeTests.cs + TwinCatProject/:
fixture scaffold with a minimal POU + README pointing at the TCBSD/ESXi
VM for e2e.
- docs/Driver.TwinCAT.Cli.md + docs/drivers/TwinCAT-Test-Fixture.md:
documentation for the above.
- docs/v3/twincat-backlog.md: forward-looking backlog seed.
Admin UI + fleet status
- src/.../Admin/Components/Pages/Clusters/DriversTab.razor + Hosts.razor:
UI refresh for fleet-status rendering.
- src/.../Admin/Hubs/FleetStatusHub.cs + FleetStatusPoller.cs +
Admin/Program.cs: SignalR hub + poller plumbing for live fleet data.
- tests/.../Admin.Tests/FleetStatusPollerTests.cs: poller coverage.
Server + redundancy runtime (Phase 6.3 follow-ups)
- src/.../Server/Hosting/RedundancyPublisherHostedService.cs: HostedService
that owns the RedundancyStatePublisher lifecycle + wires peer reachability.
- src/.../Server/Redundancy/ServerRedundancyNodeWriter.cs: OPC UA
variable-node writer binding ServiceLevel + ServerUriArray to the
publisher's events.
- src/.../Server/Program.cs + Server.csproj: hosted-service registration.
- tests/.../Server.Tests/ServerRedundancyNodeWriterTests.cs +
Server.Tests.csproj: coverage for the above.
Configuration
- src/.../Configuration/Validation/DraftValidator.cs +
tests/.../Configuration.Tests/DraftValidatorTests.cs: draft-validation
refinements.
E2E scripts (shared infrastructure)
- scripts/e2e/README.md + _common.ps1 + test-all.ps1: shared helpers + the
all-drivers test-all runner.
- scripts/e2e/test-opcuaclient.ps1: OPC UA Client e2e runner.
Docs
- docs/v2/implementation/phase-6-{1,2,3,4}*.md + exit-gate-phase-{3,7}.md:
phase-gate + implementation doc updates.
- docs/v2/plan.md: top-level plan refresh.
- docs/v2/redundancy-interop-playbook.md: client interop playbook for the
Phase 6.3 redundancy-runtime work.
Two orphan FOCAS docs remain on disk but deliberately unstaged —
docs/v2/focas-deployment.md and docs/v2/implementation/focas-simulator-plan.md
describe the now-retired Tier-C topology and should either be rewritten
or deleted in a follow-up.

The smoke tests in `TwinCAT3SmokeTests.cs` depend on this exact GVL +

PLC setup. Missing or renamed symbols surface as ADS `DeviceSymbolNotFound`

or wrong-type read failures, not silent skips.
|

`TwinCAT3SmokeTests.cs` ships 14 `[TwinCATFact]` methods plus a 16-case
|
||||
`[TwinCATTheory]` — the tests depend on the exact shapes below. Missing
|
||||
or renamed symbols surface as ADS `DeviceSymbolNotFound` or wrong-type
|
||||
read failures, not silent skips. Changed seed values will flip specific
|
||||
assertions — the load-bearing ones are called out inline.
|
||||
|
||||
### Global Variable List: `GVL_Fixture`
|
||||
### Integration-test contract
|
||||
|
||||
```st
|
||||
VAR_GLOBAL
|
||||
// Monotonically-increasing counter; MAIN increments each cycle.
|
||||
// Seed value 1234 picked so the smoke test can assert ">= 1234" without
|
||||
// synchronising with the initial cycle.
|
||||
nCounter : DINT := 1234;
|
||||
The dependency surface spans `GVL_Fixture`, `GVL_Primitives`, `GVL_Arrays`,
|
||||
`GVL_Enums`, `GVL_Plant`, and `MAIN`.
|
||||
|
||||
// Scratch REAL for write-then-read round-trip test. Smoke test writes
|
||||
// 42.5 + reads back.
|
||||
rSetpoint : REAL := 0.0;
|
||||
**`GVL_Fixture`** (source: [`PLC/GVLs/GVL_Fixture.TcGVL`](PLC/GVLs/GVL_Fixture.TcGVL))
|
||||
holds exactly three variables — `nCounter : DINT := 1234`,
|
||||
`rSetpoint : REAL := 0.0`, `bFlag : BOOL := TRUE`. `MAIN`
|
||||
(source: [`PLC/POUs/MAIN.TcPOU`](PLC/POUs/MAIN.TcPOU)) increments
|
||||
`nCounter` every cycle so the native-notification test sees monotonic
|
||||
change without writing. Seeded values aren't reliable — PlcTask
|
||||
watchdog restarts reset them — so the read test only asserts a
|
||||
non-negative DINT.
|
||||
|
||||
// Readable boolean with seed value TRUE. Reserved for future
|
||||
// expansion (e.g. discovery / symbol-browse tests).
|
||||
bFlag : BOOL := TRUE;
|
||||
END_VAR
|
||||
**`GVL_Primitives.vWord := 16#BEEF`** — the bit-indexed BOOL test pins
|
||||
to bit 3 (set in `0xBEEF`) and bit 4 (clear). Changing the seed flips
|
||||
that test.
|
||||
|
||||
**`GVL_Primitives` numeric seeds** — the primitive-type theory reads
|
||||
each of `vSInt, vUSInt, vInt, vUInt, vDInt, vUDInt, vLInt, vULInt,
|
||||
vReal, vLReal, vString` and asserts the exact seed value. Matches
|
||||
the declarations in [`PLC/GVLs/GVL_Primitives.TcGVL`](PLC/GVLs/GVL_Primitives.TcGVL).
|
||||
|
||||
**`GVL_Arrays.aReal1D[5]`** — the array round-trip test writes + reads
|
||||
element index 5. The array must be writable; don't apply read-only
|
||||
attributes.
|
||||
|
||||
**`GVL_Plant.Line1.Stations[1].Axes[1].Motor.{Temperature, Running}`** —
|
||||
the nested-UDT test reads both (LREAL + BOOL). `FB_LineSim` must be
|
||||
driving the hierarchy (see `MAIN`) so values are alive.
|
||||
|
||||
**`GVL_Enums.currentAxisState`** — the browse test asserts this symbol
|
||||
surfaces by name.
|
||||
|
||||
### Complex hierarchy (for browse / UDT / array / enum coverage)
|
||||
|
||||
All sources in [`PLC/`](PLC/). Commits are split
|
||||
one-object-per-file so XAE can "Add Existing Item" each into a fresh
|
||||
project (the `.plcproj` wrapper is environment-specific and not
|
||||
committed).
|
||||
|
||||
**Type coverage** — `GVL_Primitives` has one of every ADS primitive:
|
||||
`BOOL, BYTE, WORD, DWORD, LWORD, SINT, USINT, INT, UINT, DINT, UDINT,
|
||||
LINT, ULINT, REAL, LREAL, STRING(80), WSTRING(80), TIME, TOD, DATE, DT`.
|
||||
|
||||
**Array coverage** — `GVL_Arrays` has 1-D primitives, `ARRAY[1..4,1..4]
|
||||
OF REAL`, `ARRAY[0..2,0..2,0..2] OF DINT`, plus `ARRAY[1..4] OF ST_Axis`
|
||||
for per-element nested-struct browse.
|
||||
|
||||
**Enum + alias coverage** — `E_AxisState : DINT`, `E_Severity : INT`,
|
||||
`T_Temperature : LREAL`, `T_MeterPerSec : LREAL`. `GVL_Enums` exposes
|
||||
each at the root so tests can assert `EnumStrings` /
|
||||
`DataTypeDefinition` rendering without walking the plant hierarchy.
|
||||
|
||||
**5-level plant hierarchy** — rooted at `GVL_Plant.Line1 : ST_Line`:

1. File → New → Project → **TwinCAT XAE Project** → name
|
||||
`OtOpcUaTwinCatFixture`. This lays down the `.sln` + `.tsproj`
|
||||
scaffolding.
|
||||
2. In the Solution Explorer, right-click the `PLC` node →
|
||||
**Add New Item → Standard PLC Project** → name `PLC`. Delete the
|
||||
auto-generated stub `MAIN` — the committed one will replace it.
|
||||
3. Right-click the PLC project's `DUTs` folder → **Add → Existing Item
|
||||
…** → multi-select every file under [`PLC/DUTs/`](PLC/DUTs/) and
|
||||
**Add As Link** (so the repo stays the source of truth). Repeat for
|
||||
`GVLs/` → [`PLC/GVLs/`](PLC/GVLs/) and `POUs/` →
|
||||
[`PLC/POUs/`](PLC/POUs/).
|
||||
4. Assign `MAIN` to `PlcTask` (cyclic, 10 ms, priority 20).
|
||||
5. Set the target system to the TCBSD / XAR VM via the AMS route, then
|
||||
**Build → Build Solution** + **Activate Configuration → Run Mode**.
|
||||
|
||||
If XAE complains about missing references while importing, add the DUTs
