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 AB CIP driver (ControlLogix / CompactLogix /
|
|
Micro800 / GuardLogix) bridged through the OtOpcUa server.
|
|
|
|
.DESCRIPTION
|
|
Mirrors test-modbus.ps1 but against libplctag's ab_server (or a real Logix
|
|
controller). Five assertions: probe / driver-loopback / forward-bridge /
|
|
reverse-bridge / subscribe-sees-change.
|
|
|
|
Prereqs:
|
|
- ab_server container up (tests/.../AbCip.IntegrationTests/Docker/docker-compose.yml,
|
|
--profile controllogix) OR a real PLC on the network.
|
|
- OtOpcUa server running with an AB CIP DriverInstance pointing at the
|
|
same gateway + a Tag published at the -BridgeNodeId you pass.
|
|
|
|
.PARAMETER Gateway
|
|
ab://host[:port]/cip-path. Default ab://127.0.0.1/1,0 (ab_server ControlLogix).
|
|
|
|
.PARAMETER Family
|
|
ControlLogix / CompactLogix / Micro800 / GuardLogix (default ControlLogix).
|
|
|
|
.PARAMETER TagPath
|
|
Logix symbolic path to exercise. Default 'TestDINT' — matches the ab_server
|
|
--tag=TestDINT:DINT[1] seed.
|
|
|
|
.PARAMETER OpcUaUrl
|
|
OtOpcUa server endpoint.
|
|
|
|
.PARAMETER BridgeNodeId
|
|
NodeId at which the server publishes the TagPath.
