Joseph Doherty 0575280a3b Phase 3 PR 62 -- Siemens S7 native driver project scaffold (S7comm via S7netplus). First non-Modbus in-process driver. Creates src/ZB.MOM.WW.OtOpcUa.Driver.S7 (.NET 10, x64 -- S7netplus is managed, no bitness constraint like MXAccess) + tests/ZB.MOM.WW.OtOpcUa.Driver.S7.Tests + slnx entries. Depends on S7netplus 0.20.0 which is the latest version on NuGet resolvable in this cache (0.21.0 per driver-specs.md is not yet published; 0.20.0 covers the same Plc+CpuType+ReadAsync surface). S7DriverOptions captures the connection settings documented in driver-specs.md \u00A75: Host, Port (default 102 ISO-on-TCP), CpuType (default S71500 per most-common deployment), Rack=0, Slot=0 (S7-1200/1500 onboard PN convention; S7-300/400 operators must override to slot 2 or 3), Timeout=5s, Tags list + Probe settings with default MW0 probe address. S7TagDefinition uses S7.Net-style address strings (DB1.DBW0, M0.0, I0.0, QD4) with an S7DataType enum (Bool, Byte, Int16, UInt16, Int32, UInt32, Int64, UInt64, Float32, Float64, String, DateTime -- the full type matrix from the spec); StringLength defaults to 254 (S7 STRING max). S7Driver implements the IDriver-only subset per the PR plan: InitializeAsync opens a managed Plc with the configured CpuType + Host + Rack + Slot, pins WriteTimeout / ReadTimeout on the underlying TcpClient, awaits Plc.OpenAsync with a linked CTS bounded by Options.Timeout so the ISO handshake itself respects the configured bound; health transitions Unknown -> Initializing -> Healthy on success or Unknown -> Initializing -> Faulted on handshake failure, with a best-effort Plc.Close() on the faulted path so retries don't leak the TcpClient. ShutdownAsync closes the Plc and flips health back to Unknown. DisposeAsync routes through ShutdownAsync + disposes the SemaphoreSlim. Internal Gate + Plc accessors are exposed to the test project (InternalsVisibleTo) so PRs 63-65 can stack read/write/subscribe on the same serialization semaphore per the S7netplus documented 'one Plc per PLC, SemaphoreSlim-serialized' pattern. ITagDiscovery, IReadable, IWritable, ISubscribable, IHostConnectivityProbe are all deliberately omitted from this PR -- they depend on the S7AddressParser (PR 63) and land sequenced in PRs 64-65. Unit tests (S7DriverScaffoldTests, 5 facts): default options target S7-1500 / port 102 / slot 0, default probe interval 5s, tag defaults to writable with StringLength 254, driver reports DriverType=S7 + Unknown health pre-init, Initialize against RFC-5737 reserved IP 192.0.2.1 with 250ms timeout transitions to Faulted and throws (tests the connect-failure path doesn't leave the driver in an ambiguous state). 5/5 pass. dotnet build ZB.MOM.WW.OtOpcUa.slnx: 0 errors. No regression in Modbus / Galaxy suites. PR 63 ships S7AddressParser next, PR 64 wires IReadable/IWritable over S7netplus, PR 65 adds discovery + polling-overlay subscribe + probe.
