AB CIP PR 9-12 — Per-PLC-family profile tests + GuardLogix safety-tag support. Consolidates PRs 9/10/11/12 from the plan (ControlLogix / CompactLogix / Micro800 / GuardLogix integration suites) into a single PR because the per-family work that actually ships without a live ab_server binary is profile-metadata assertion + unit-level driver-option binding. Per-family integration tests that require a running simulator are deferred to the ab_server-CI follow-up already tracked from PR 3 (download prebuilt Windows binary as GitHub release asset). ControlLogix — baseline profile asserted (controllogix attribute, 4002 LFO ConnectionSize, 1,0 default path, request-packing + connected-messaging, 4000B max fragment). CompactLogix — narrower 504 ConnectionSize for 5069-L3x safety, 500B max fragment, lib attribute compactlogix which libplctag maps to the ControlLogix family internally but via our profile chain we surface it as a distinct knob so future quirk handling (5069 narrow-window regression cases) hangs off the compactlogix attribute. Micro800 — empty CIP path for no-backplane routing, 488B ConnectionSize, 484B fragment cap, request packing + connected messaging both disabled (most models reject Forward_Open), micro800 lib attribute. Test asserts the driver correctly parses an ab://192.168.1.20/ host address with empty path + forwards the empty path through AbCipTagCreateParams so libplctag sees the unconnected-only configuration. GuardLogix — wire protocol identical to ControlLogix (safety partition is a per-tag concern, not a wire-layer distinction) so profile defaults match ControlLogix. New AbCipTagDefinition.SafetyTag field — when true, the driver forces SecurityClassification.ViewOnly in discovery regardless of the Writable flag, and IWritable rejects the write upfront with BadNotWritable. Matches the Rockwell safety-partition isolation model where non-safety-task writes to safety tags would be rejected by the PLC anyway — surfacing the intent at the driver surface prevents wasted wire round-trips + gives Admin UI users a correct ViewOnly rendering. 14 new unit tests in AbCipPlcFamilyTests covering — ControlLogix profile defaults + correct profile selection at Initialize, CompactLogix narrower-than-ControlLogix ConnectionSize + fragment cap, Micro800 empty path parses + SupportsConnectedMessaging=false + SupportsRequestPacking=false + read forwards empty path + micro800 attribute through to libplctag, GuardLogix wire-protocol parity with ControlLogix, GuardLogix safety tag surfaces as ViewOnly in discovery even when Writable=true, GuardLogix safety-tag write rejected with BadNotWritable even when Writable=true, ForFamily theory (4 families → correct libplctag attribute). Total AbCip unit tests now 161/161 passing (+14 from PR 8's 147). Modbus + other drivers untouched; full solution builds 0 errors. PR 13 (IAlarmSource via tag-projected ALMA/ALMD blocks) remains deferred per the plan — feature-flagged pattern not needed before go-live.

Also seeds a coil at bit-addr 400 (= cell 25 bit 0) and a discrete input at bit-addr 500 (= cell 31 bit 0) so future S7-specific tests for FC01/FC02 have stable markers. shared blocks=true to match the proven dl205.json pattern (pymodbus's bits/uint16 cells coexist cleanly when addresses don't collide). Write list references cells (0, 25, 100-101, 200-209, 300-301), not bit addresses -- pymodbus's write-range entries are cell-indexed, not bit-indexed. Adds tests/ZB.MOM.WW.OtOpcUa.Driver.Modbus.IntegrationTests/S7/ directory with S7_1500Profile.cs (mirrors DL205Profile pattern: SmokeHoldingRegister=200, SmokeHoldingValue=4321, BuildOptions tags + probe-disabled + 2s timeout) and S7_1500SmokeTests.cs (single fact S7_1500_roundtrip_write_then_read_of_holding_register that writes SmokeHoldingValue then reads it back, asserting both write status 0 and read status 0 + value equality). Gates on MODBUS_SIM_PROFILE=s7_1500 so the test skips cleanly against other profiles. csproj updated to copy S7/** to test output as PreserveNewest (pattern matching DL205/**).

Verified end-to-end: smoke test 1/1 passes against the running pymodbus s7_1500 profile (localhost:5020 FC06 write of 4321 at HR[200] + FC03 read back). 143/143 Modbus.Tests pass, no regression in driver code because this PR is purely test-asset. Per-quirk S7 integration tests (ABCD word order default, FC23 IllegalFunction, MB_SERVER STATUS 0x8383 behaviour, port-per-connection semantics) land in PR 57+.

AB CIP PR 3 — IReadable implementation against libplctag. Introduces IAbCipTagRuntime + IAbCipTagFactory abstraction matching the Modbus transport-factory pattern (ctor optional arg, default production impl injected) so the driver's read/status-mapping logic is unit-testable without a live PLC or the native libplctag binary. LibplctagTagRuntime is the default wire-backed implementation — wraps libplctag.Tag + translates our AbCipDataType enum into GetInt8/GetUInt8/GetInt16/GetUInt16/GetInt32/GetUInt32/GetInt64/GetUInt64/GetFloat32/GetFloat64/GetString/GetBit calls covering Bool (standalone + BOOL-in-DINT via .N bit selector), SInt/USInt, Int/UInt, DInt/UDInt, LInt/ULInt, Real, LReal, String, Dt (epoch DINT), with Structure deferred to PR 6. MapPlcType bridges our libplctag attribute strings (controllogix, compactlogix, micro800) to libplctag.PlcType enum; CompactLogix rolls under ControlLogix per libplctag's family grouping which matches the wire protocol reality. AbCipDriver now implements IReadable — ReadAsync iterates fullReferences preserving order, looks up each tag definition + its device, lazily materialises the tag runtime via EnsureTagRuntimeAsync on first touch (cached thereafter for the lifetime of the device), catches OperationCanceledException to honor cancellation, maps libplctag non-zero status via AbCipStatusMapper.MapLibplctagStatus, catches any other exception as BadCommunicationError. Health surface moves to Healthy on success + Degraded with the last error message on failure. Initialize-failure path disposes the half-created runtime before rethrowing so no native handles leak. DeviceState gains a Runtimes dict alongside the existing TagHandles collection; DisposeHandles walks both so ShutdownAsync + ReinitializeAsync cleanly destroy every native tag. 12 new unit tests in AbCipDriverReadTests using FakeAbCipTag / FakeAbCipTagFactory (test fake under tests/...AbCip.Tests/FakeAbCipTag.cs) covering unknown reference → BadNodeIdUnknown, unknown device → BadNodeIdUnknown, successful DInt read with correct Good status + captured value, lazy-init on first read with reuse across subsequent reads, non-zero libplctag status mapping via AbCipStatusMapper, exception during read surfacing as BadCommunicationError with health Degraded, batched reads preserving order + per-tag status, health Healthy after success, TagCreateParams composition from device + profile (gateway / port / CIP path / libplctag attribute / tag name wiring), cancellation propagation via OperationCanceledException, ShutdownAsync disposing every runtime, Initialize-failure disposing the aborted runtime. Total AbCip unit tests now 88/88 passing. Integration test project scaffolding — tests/ZB.MOM.WW.OtOpcUa.Driver.AbCip.IntegrationTests with AbServerFixture (IAsyncLifetime that starts ab_server when the binary is on PATH, otherwise marks IsAvailable=false), AbServerFact attribute (Fact-equivalent that skips when ab_server is missing), one smoke test exercising DInt read end-to-end. Project runs cleanly — the single smoke test skips on boxes without ab_server (0 failed, 0 passed, 1 skipped) + runs on boxes with it. Follow-up work captured in comments — ab_server CI fixture (download prebuilt Windows x64 binary as GitHub release asset) + per-family JSON profiles + hand-rolled CIP stub for UDT fidelity ship in the PR 6/9-12 window. Solution file updated. Full solution builds 0 errors across all 28 projects. Modbus + other existing tests untouched.

LmxOpcUa

OPC UA server and cross-platform client tools for AVEVA System Platform (Wonderware) Galaxy. The server exposes Galaxy tags via MXAccess as an OPC UA address space. The client stack provides a shared library, CLI tool, and Avalonia desktop application for browsing, reading/writing, subscriptions, alarms, and historical data.

Server

The OPC UA server runs on .NET Framework 4.8 (x86) and bridges the Galaxy runtime to OPC UA clients.

Server Prerequisites

  • .NET Framework 4.8 SDK
  • AVEVA System Platform with ArchestrA Framework installed
  • Galaxy repository database (SQL Server, Windows Auth)
  • MXAccess COM registered (LMXProxy.LMXProxyServer)
  • Wonderware Historian (optional, for historical data access)
  • Windows (required for COM interop and MXAccess)

Build and Run Server

dotnet restore ZB.MOM.WW.LmxOpcUa.slnx
dotnet build src/ZB.MOM.WW.LmxOpcUa.Host
dotnet run --project src/ZB.MOM.WW.LmxOpcUa.Host

The server starts on opc.tcp://localhost:4840/LmxOpcUa with the None security profile by default. Configure Security.Profiles in appsettings.json to enable Basic256Sha256-Sign or Basic256Sha256-SignAndEncrypt for transport security. See Security Guide.

Install as Windows Service

cd src/ZB.MOM.WW.LmxOpcUa.Host/bin/Debug/net48
ZB.MOM.WW.LmxOpcUa.Host.exe install
ZB.MOM.WW.LmxOpcUa.Host.exe start

Service logon requirement: The service must run under a Windows account that has access to the AVEVA Galaxy and Historian. The default LocalSystem account can connect to MXAccess and SQL Server but cannot authenticate with the Historian SDK (HCAP). Configure the service to "Log on as" a domain or local user that is a recognized ArchestrA platform user. This can be set in services.msc or during install with ZB.MOM.WW.LmxOpcUa.Host.exe install -username DOMAIN\user -password ***.

Run Server Tests

dotnet test tests/ZB.MOM.WW.LmxOpcUa.Tests
dotnet test tests/ZB.MOM.WW.LmxOpcUa.IntegrationTests

Client Stack

The client stack is cross-platform (.NET 10) and consists of three projects sharing a common IOpcUaClientService abstraction. No AVEVA software or COM is required — the clients connect to any OPC UA server.

Client Prerequisites

  • .NET 10 SDK
  • No platform-specific dependencies (runs on Windows, macOS, Linux)
