Marc SchierandCopilot c48c8b93dd Positioning: OPC 10000-210 RSL and 10000-211 GPOS on one geolocation provider (#4125)
**Stack 3/5** — base #4124. Part of the #4096 split; see #4096 for the
overall picture.

> Review after #4123 and #4124.

## What this is

The OPC 10000-210 Relative Spatial Location and OPC 10000-211 Global
Positioning companion models, with their server and client libraries,
plus the ISA-95 migration onto the shared geolocation seam.

## Why it is one change

A deployment writes **one** provider implementation and both OPC
10000-211 and OPC 10030 are served from it. The specifications disagree
on representation, not on content:

- GPOS publishes the structured `GlobalLocationDataType` and validates
the EPSG code against the configured CRS.
- ISA-95 publishes the same sample as the `String` array that OPC 10030
§8.3.2.2 requires.

Splitting them would mean two provider interfaces for one physical
sensor, which is exactly what this avoids. The seam itself lives in
`Opc.Ua.Server` and landed in 1/5.

## Contents

- `Opc.Ua.Positioning`, `.Server` and `.Client`.
- `Opc.Ua.ISA95.Server` moves onto `IGeoLocationProvider`; the three
ISA-95-specific provider files are removed because the shared seam and
its in-memory implementation replace them.
- **Fixes a conformance gap**: the ISA-95 binder wrote a scalar where
the type declares `ValueRank` OneOrMoreDimensions. It now writes
`String[]`.
- **Fixes a liveness bug**: a provider that cannot push is polled at the
Variable's `MinimumSamplingInterval` rather than installed once, so a
non-pushing provider no longer serves its start-up sample with `Good`
status forever.
- `samples/MinimalIsa95Server`.

## Validation

`dotnet build UA.slnx` — 0 errors.

Minimal ISA-95 Server

This sample hosts the OPC-10030 ISA-95 common model together with OPC-10031-4 Job Control V1 and V2.

It uses the typed common-model builder, a provider-backed GeoSpatialLocationType, and the reusable in-memory Job Control provider. The seeded V2 job demonstrates the StoreAndStart and automatic AllowedToStart to Running transition.

Running

dotnet run --project samples\MinimalIsa95Server\MinimalIsa95Server.csproj

The server listens on opc.tcp://localhost:62545/MinimalIsa95Server by default (override with --port).

What this sample demonstrates

  • Server registration via services.AddOpcUa().AddServer(...).AddIsa95Server().ConfigureModel(...).
  • Populating the OPC-10030 common model: Personnel, Equipment, PhysicalAsset, and the full Material class/definition/lot/sublot hierarchy, including DefinedByMaterialClass and MadeUpOfMaterialSublot.
  • Binding a GeoSpatialLocationType instance to the shared InMemoryGeoLocationProvider, seeded with a fixed WGS84 position that is published as WKT.
  • Seeding a Job Control V2 job order (DemoJobSeeder) with StoreAndStart followed by the automatic execution-controller BeginExecution transition to Running.

See the ISA-95 developer guide for the full hosting model, the Job Control V1/V2 state engine, the two documented normative NodeSet repairs, and a conformance matrix.
