> Tracking issue #4576. #4577, #4578 and #4579 are merged, so this branch is > rebased onto `master` and contains only the Scales and PackML commits. ## Summary Last of the four PRs of #4576. Adds OPC 40200 Weighing Technology 2.00 as a model package plus a server and a client SDK, and the OPC 30050 PackML model it composes. | Package | Content | |---|---| | `Opc.Ua.PackML` | OPC 30050 PackML 1.01, plus `PackMLStateMachineController`, which drives a base state machine together with its nested machine and execute state machines (activation and deactivation of the sub-state machines, the PackML methods with an `Executable` attribute that follows the state, acting states left automatically or by the equipment) | | `Opc.Ua.Scales` | OPC 40200 2.00 (`http://opcfoundation.org/UA/Scales/V2/`), generated from the unmodified UA-Nodeset publication, plus the contracts client and server share | | `Opc.Ua.Scales.Server` | `AddScales()` / `ConfigureScales(...)`; all fourteen scale kinds and scale systems below `DeviceSet` and `Machines`; a runtime that does the weighing arithmetic (ranges, rounding to d or e, zero band, overload/underload, zero, tare, preset tare, registration), production presets with DI locking, statistics, recipes and recipe files, Annex C events and alarms over a `HasNotifier` hierarchy, and the methods of every scale type | | `Opc.Ua.Scales.Client` | discovery, weight reads and streaming, zero/tare/register, products, PackML state and commands, type-specific methods, events and alarms, snapshots | `docs/Scales.md` includes a conformance matrix against the 21 OPC 40200 server facets with test evidence, the places where the specification and the NodeSet disagree, and known limitations. ## Review follow-ups Separate commits after the docs/samples commit, each with a test that fails without it where the defect can be observed. - Copilot review: `CurrentProductsChanged` fires only when the set of current products changes; the new public collection APIs (`ScalesServerOptions.AdditionalNamespaceUris`, `ScaleNamespaceIndices.SearchOrder`, `ScalesModel.AllKinds`) are `ArrayOf<T>`. - Own review with the rubric in `.github/copilot-instructions.md`: - PackML raises `StateChanged` after its lock is released (queued, in order), reads `StartParameters` under the lock, and reports the handler's status when an acting state cannot complete. - Scales: concurrent first creations share one runtime (the lock service refused a second attach); two creations of the same name cannot both publish; a removed product id stays reserved until its node is gone; the zone, target-count and vehicle handlers change products under the preset lock; the product factory and `configure` delegate run outside it; the recipe upload reads `ActiveRecipe` under the lock; resetting the statistics also resets the tolerance percentage. - The client lets a failed browse call propagate instead of reading it as "no children". ## Testing - `tests/Opc.Ua.Scales.Tests`: 115 tests on net8 and net10 and with the netstandard2.1 libraries, including the PackML runtime; the client/server tests connect a real session over `opc.tcp` to a hosted `ScalesNodeManager`. - `UA.slnx` builds for net472, net48, netstandard2.0/2.1 and net8/9/10 with SDK 10.0.401 and no new warnings. - Changed-line coverage of this layer (`check-coverage.ps1`): 94.59 % (4585 of 4847 changed lines, against `master`). - Fork CI, full PR matrix incl. macOS: in progress, [run 36676067489](https://github.com/biancode/UA-.NETStandard/actions/runs/36676067489); CodeQL: in progress, [run 36676070427](https://github.com/biancode/UA-.NETStandard/actions/runs/36676070427). - On the current `master` (with Pumps merged), `UA.slnx` builds for every target framework and the Scales and Pumps tests pass. - Beyond the in-repo tests the implementation has been validated end to end against a separate, non-public OPC UA client and server. ## Reviewing Commits: PackML → Scales model → server → client → tests → docs and samples → review follow-ups.
