The original three-stage design (probe / driver-loopback / forward-
bridge) only proved driver-write → server-read. It missed:
- OPC UA write → server → driver → PLC (the reverse direction)
- server-side data-change notifications actually firing (a stale
subscription can still let a read-after-the-fact return the new
value and look fine)
Extend _common.ps1 with two helpers:
- Test-OpcUaWriteBridge: otopcua-cli write the NodeId -> wait 3s ->
driver CLI read the PLC side, assert equality.
- Test-SubscribeSeesChange: Start-Process otopcua-cli subscribe in the
background with --duration N, settle 2s, driver-side write, wait for
the subscription window to close, assert captured stdout contains
the new value.
Wire both into test-modbus / test-abcip / test-ablegacy / test-s7 /
test-focas / test-twincat after the existing forward-bridge stage.
Update README to describe the five-stage design + note that the
published NodeId must be writable for stages 4 + 5.
Also prepend UTF-8 BOM to every script in scripts/e2e so Windows
PowerShell 5.1 parsers agree on em-dash byte sequences the way
PowerShell 7 already does. The scripts still #Requires -Version 7.0 —
the BOM is purely defensive for IDE / CI step parsers.

The driver-layer integration tests confirm the driver sees the PLC, and
the Client.CLI tests confirm the client sees the server. Nothing glued
them end-to-end until this PR.
- scripts/e2e/_common.ps1: shared helpers — CLI invocation (published-
binary OR `dotnet run` fallback), Test-Probe / Test-DriverLoopback /
Test-ServerBridge (all return @{Passed;Reason} hashtables).
- scripts/e2e/test-<modbus|abcip|ablegacy|s7|focas|twincat>.ps1: per-
driver three-stage script (probe → driver-loopback → server-bridge).
AB Legacy / FOCAS / TwinCAT are gated behind *_TRUST_WIRE env vars
since they need real hardware (#222) or a licensed runtime (#221).
- scripts/e2e/test-phase7-virtualtags.ps1: writes a Modbus HR, reads
the server-side VirtualTag (VT = input * 2) back via OPC UA, triggers
+ clears a scripted alarm. Exercises the Phase 7 CachedTagUpstreamSource
+ ScriptedAlarmEngine path.
- scripts/e2e/test-all.ps1: reads e2e-config.json sidecar, runs each
present driver, prints a FINAL MATRIX (PASS/FAIL/SKIP). Missing
sections SKIP rather than fail hard.
- scripts/e2e/e2e-config.sample.json: commented sample — each dev's
NodeIds are local-seed-specific so e2e-config.json is .gitignore-d.
- scripts/e2e/README.md: full walkthrough — prereqs, three-stage design,
env-var gates, expected matrix, why this is separate from `dotnet test`.
Tasks #249-#251 shipped Modbus/AbCip/AbLegacy/S7/TwinCAT CLIs but left
FOCAS out. Since test-focas.ps1 needs it, the 6th CLI ships here:
- src/ZB.MOM.WW.OtOpcUa.Driver.FOCAS.Cli: probe/read/write/subscribe
commands, AssemblyName `otopcua-focas-cli`. WriteCommand.ParseValue
handles the full FocasDataType enum (Bit/Byte/Int16/Int32/Float32/
Float64/String — no UInt variants; the FOCAS protocol exposes signed
PMC + Fanuc-Float only). Default DataType is Int16 to match the PMC
register convention.
Full-solution build clean (0 errors). FOCAS CLI wired into
ZB.MOM.WW.OtOpcUa.slnx. No .Tests project for the FOCAS CLI yet —
symmetric with how ProbeCommand has no unit-testable pure logic in the
other 5 CLIs either; WriteCommand.ParseValue parity will land in a
follow-up to keep this PR scoped.
