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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

.SYNOPSIS
|
|
End-to-end CLI test for the TwinCAT (Beckhoff ADS) driver.
|
|
|
|
.DESCRIPTION
|
|
Requires a reachable AMS router (local TwinCAT XAR, Beckhoff.TwinCAT.Ads.
|
|
TcpRouter NuGet, or an authorised remote AMS route) + a live TwinCAT
|
|
runtime on -AmsNetId. Without one the driver surfaces a transport error
|
|
on InitializeAsync + the script's probe fails.
|
|
|
|
Set TWINCAT_TRUST_WIRE=1 to promise the endpoint is live. Without it the
|
|
script skips (task #221 tracks the 7-day-trial CI fixture — until that
|
|
lands, TwinCAT testing is a manual operator task).
|
|
|
|
.PARAMETER AmsNetId
|
|
AMS Net ID of the target (e.g. 127.0.0.1.1.1 for local XAR,
|
|
192.168.1.40.1.1 for a remote PLC).
|
|
|
|
.PARAMETER AmsPort
|
|
AMS port. Default 851 (TC3 PLC runtime). TC2 uses 801.
|
|
|
|
.PARAMETER SymbolPath
|
|
TwinCAT symbol to exercise. Default 'MAIN.iCounter' — substitute with
|
|
whatever your project actually declares.
|
|
|
|
.PARAMETER OpcUaUrl
|
|
OtOpcUa server endpoint.
|
|
|
|
.PARAMETER BridgeNodeId
|
|
NodeId at which the server publishes the Symbol.
