Audit (three parallel agent passes) found 43 markdown files carrying stale references to the deleted Galaxy.Host/Proxy/Shared projects after the v2-mxgw merge. This commit lands the prioritized fixes. Track 1 — high-traffic in-place rewrites (3 files, ~454 lines deleted) - README.md (202 → 91 lines): drops .NET 4.8 / x86 / TopShelf install text; leads with the multi-driver .NET 10 server identity and points at scripts/install/Install-Services.ps1 and the parity rig. - docs/v2/driver-specs.md §1 Galaxy (~289 → ~66 lines): replaces the Tier-C out-of-process spec with a Tier-A in-process description matching the current GalaxyDriver code, with the four-section GalaxyDriverOptions JSON shape pulled verbatim from Config/GalaxyDriverOptions.cs. - docs/drivers/Galaxy.md (211 → 92 lines): full rewrite around the current Browse/Runtime/Health/Config sub-folders. Track 2 — historical banners (5 files) - lmx_mxgw.md, lmx_mxgw_impl.md, lmx_backend.md, docs/v2/Galaxy.ParityMatrix.md, docs/v2/implementation/phase-2-galaxy-out-of-process.md each get a "✅ Completed 2026-04-30 — historical record" banner block. lmx_mxgw.md also fixes two dead links (`docs/Galaxy.Driver.md` and `docs/v2/Galaxy.Driver.md`) → `docs/drivers/Galaxy.md`. Track 3 — v1 archive sweep (10 git mv + 1 new index + 2 in-place scrubs) - Moved 10 v1 docs under docs/v1/ preserving subpath structure: AlarmTracking, Configuration, DataTypeMapping, HistoricalDataAccess, Subscriptions (top-level); drivers/Galaxy-Repository, drivers/Galaxy-Test-Fixture; reqs/GalaxyRepositoryReqs, reqs/MxAccessClientReqs, reqs/ServiceHostReqs. - New docs/v1/README.md is the shared archive banner + per-file table. - docs/README.md repointed to the v1 paths and updated to reflect the v2 two-process deploy shape (Server + Admin + optional OtOpcUaWonderwareHistorian). - docs/v2/Galaxy.ParityRig.md got a historical banner + four inline scrubs marking the OtOpcUaGalaxyHost service / Driver.Galaxy.Host EXE / Driver.Galaxy.ParityTests project as deleted-in-PR-7.2. The repo's live-reading surface (README + CLAUDE.md + docs/v2/) now describes only the post-PR-7.2 architecture. v1 docs are preserved as a labelled archive under docs/v1/.

OtOpcUa
OPC UA server (.NET 10 AnyCPU) that exposes a fleet of industrial drivers as a single OPC UA address space. Drivers ship in-process for AVEVA System Platform Galaxy (via the sibling mxaccessgw repo), Modbus TCP, Siemens S7, Allen-Bradley CIP (ControlLogix / CompactLogix), Allen-Bradley Legacy (SLC 500 / MicroLogix), Beckhoff TwinCAT (ADS), FANUC FOCAS, and OPC UA Client (gateway).
A cross-platform client stack (.NET 10) — shared library, CLI, and Avalonia desktop app — connects to any OPC UA server.

MXAccess COM (x86 worker, on AVEVA box)
Galaxy is the only driver with an external runtime: it speaks gRPC to a separately installed mxaccessgw server (sibling repo at c:\Users\dohertj2\Desktop\mxaccessgw\) which owns the MXAccess COM apartment and the x86/STA bitness constraint server-side. Everything in this repo is platform-agnostic .NET 10.
Prerequisites
- .NET 10 SDK (server, drivers, clients all target .NET 10)
- SQL Server reachable for the central config DB
- For Galaxy specifically: a running
mxaccessgwdeployment — see docs/v2/Galaxy.ParityRig.md - For Wonderware Historian read-back: optional
OtOpcUaWonderwareHistoriansidecar — see docs/ServiceHosting.md
Quick Start
dotnet restore ZB.MOM.WW.OtOpcUa.slnx
dotnet build ZB.MOM.WW.OtOpcUa.slnx
dotnet test ZB.MOM.WW.OtOpcUa.slnx
# Run the server in dev (foreground)
dotnet run --project src/ZB.MOM.WW.OtOpcUa.Server
The server starts on opc.tcp://localhost:4840 with the None security profile. Configure Security.Profiles in src/ZB.MOM.WW.OtOpcUa.Server/appsettings.json to enable Basic256Sha256-Sign or Basic256Sha256-SignAndEncrypt. See docs/security.md.
Install as Windows Services
Production deployment is driven by scripts/install/Install-Services.ps1, which registers the OtOpcUa server service (and optionally the OtOpcUaWonderwareHistorian sidecar) under a chosen service account. Galaxy support requires a separately installed mxaccessgw — neither this repo nor the install script provisions it.
.\scripts\install\Install-Services.ps1 `
-InstallRoot 'C:\Program Files\OtOpcUa' `
-ServiceAccount 'DOMAIN\svc-otopcua'
Add -InstallWonderwareHistorian for the historian sidecar. See the script header and docs/ServiceHosting.md for full options.
Client CLI
dotnet run --project src/ZB.MOM.WW.OtOpcUa.Client.CLI -- connect -u opc.tcp://localhost:4840
dotnet run --project src/ZB.MOM.WW.OtOpcUa.Client.CLI -- browse -u opc.tcp://localhost:4840 -r -d 3
dotnet run --project src/ZB.MOM.WW.OtOpcUa.Client.CLI -- read -u opc.tcp://localhost:4840 -n "ns=2;s=SomeNode"
dotnet run --project src/ZB.MOM.WW.OtOpcUa.Client.CLI -- write -u opc.tcp://localhost:4840 -n "ns=2;s=SomeNode" -v 42
dotnet run --project src/ZB.MOM.WW.OtOpcUa.Client.CLI -- subscribe -u opc.tcp://localhost:4840 -n "ns=2;s=SomeNode" -i 500
