The libplctag adapters assigned Tag.Path straight from the device's parsed
CipPath. A device address with no route (ab://host:44818/ - the normal
Micro800 form, and a MicroLogix with no route) parses to "", and libplctag
rejects an empty path attribute with ErrorBadData; omitting the attribute
(null) is what it accepts. So Micro800 could not connect on the default
libplctag transport.
This predates the native transport work and exists on master.
Add an internal LibplctagPath.Normalize helper per driver project (blank ->
null) and route all four Tag constructions through it (AbCip tag runtime,
symbol-list enumerator, template reader; AbLegacy tag runtime). The runtime
tag construction is extracted to an internal BuildTag so tests can inspect
Tag.Path without connecting. Tests fail with Normalize reverted to identity.
Update the Micro800 smoke-test comment: both transports are expected to pass.
Replace pre-declared options.Tags (typed <Driver>TagDefinition lists) with
options.RawTags (IReadOnlyList<RawTagEntry>) across all 6 Docker-gated driver
integration suites so they COMPILE against the v3 driver API.
Each project gets a local <Driver>RawTags helper mirroring the unit-test
project's helper: it serialises a typed def back to its TagConfig blob via the
driver's <Driver>TagDefinitionFactory.ToTagConfig and packages it as a
RawTagEntry (RawPath = def.Name; DeviceName = def.DeviceHostAddress for the
multi-device drivers AbCip/AbLegacy/TwinCAT/FOCAS). Test intent (addresses,
data types, device routing, assertions) is unchanged — only the
tag-authoring/config-delivery shape was migrated.
Docker-gated: these still skip at runtime without fixtures; COMPILE is the gate.
Adds <summary>, <param>, <typeparam>, and <inheritdoc/> tags to public
members surfaced by commentchecker — resolves 5,847 of 5,869 issues
(99.6%) across three /fixdocs passes.
Two real bugs uncovered by re-running with the new fixture defaults
pointing at the shared docker host. Both are test-side, not driver-side.
AbCip — Driver_reads_seeded_DInt_from_ab_server (4 parametrized rows):
Hardcoded 'ab://127.0.0.1:{port}/1,0' in the deviceUri instead of
the resolved fixture.Host. The new 10.100.0.35 default (and any
AB_SERVER_ENDPOINT override) silently couldn't reach this test —
the driver tried to connect to a non-existent localhost:44818 and
returned BadCommunicationError on all 4 profile rows. The sibling
Emulate tests already use the fixture's resolved endpoint; this
smoke test was missed in the original migration.
Fix: deviceUri = $"ab://{fixture.Host}:{fixture.Port}/1,0".
Modbus — Float32_With_CDAB_Roundtrips_Through_Wire:
Test wrote a Float32 to HR 100 (2 consecutive registers: 100+101).
standard.json's writable HR range declares [100,100] only — a
single-cell auto-incrementing register, not a 2-register pair. The
write to register 101 was rejected with Illegal Data Address
(BadOutOfRange).
Fix: moved the tag from HR 100 to HR 200 (in standard.json's
'[200, 209]' scratch range — 10 consecutive writable HRs). The
Float32+CDAB semantic the test exercises is unchanged.
Modbus — Block_Read_Coalescing_Reduces_PDU_Count_End_To_End:
Test read HR 300, 302, 304 — outside both the writable ranges and
the uint16 seed list. pymodbus rejects reads to unseeded HRs even
though 'hr size' is 2048. BadOutOfRange on every read.
Fix: moved the tags from 300/302/304 to 200/202/204 (within the
scratch range). The non-contiguous coalescing semantic (3 tags
inside a 5-register window with MaxReadGap=5) is preserved.
After this commit:
- Modbus.IntegrationTests: 6/38 pass / 32 skip / 0 fail
(was 4 pass / 32 skip / 2 fail; 32 skips are profile-gated
ExceptionInjectionTests — they need MODBUS_SIM_PROFILE=
exception_injection and a different container, intentional gating)
- AbCip.IntegrationTests: 10/12 pass / 2 skip / 0 fail
(was 6 pass / 2 skip / 4 fail; 2 skips are Emulate tests that
need the fixture for separate scenarios)
No driver code changed.

Group all 69 projects into category subfolders under src/ and tests/ so the
Rider Solution Explorer mirrors the module structure. Folders: Core, Server,
Drivers (with a nested Driver CLIs subfolder), Client, Tooling.
- Move every project folder on disk with git mv (history preserved as renames).
- Recompute relative paths in 57 .csproj files: cross-category ProjectReferences,
the lib/ HintPath+None refs in Driver.Historian.Wonderware, and the external
mxaccessgw refs in Driver.Galaxy and its test project.
- Rebuild ZB.MOM.WW.OtOpcUa.slnx with nested solution folders.
- Re-prefix project paths in functional scripts (e2e, compliance, smoke SQL,
integration, install).
Build green (0 errors); unit tests pass. Docs left for a separate pass.
