Servo (0x0056) and spindle (0x0040) meter records are 8 bytes:
[i32 value][u16 base][u16 exponent], the same self-describing envelope as the
position blocks.
Servo: offset 4 was read as a decimal count. It is the BASE (a steady 10), so
every load was divided by 10^10 and published ~0 -- the sister ignitionoee panel
read servo 0% on every axis of a Makino cutting at 20,000 rpm. Loads are now
value / base^exponent, a direct percentage.
Spindle: the raw meter is a 1/16384 fraction of full scale. Settled on the real
Z-34184 by regressing the type-1 meter against cnc_rddynamic2 spindle speed over
596..20,000 rpm (rpm = 1.220749 x meter; 16384 x 1.220749 = 20000.75). So:
- Spindle/{name}/Load publishes % of rated load (Float64; was the raw Int32
count -- a reading of 9155 meant 55.9%).
- Spindle/{name}/MaxRpm is RENAMED Spindle/{name}/MotorSpeedPct (Float64, % of
maximum speed) and is polled with Load. The old node was actively wrong: the
type-1 meter is the live motor speed, and it was read once at bootstrap and
served forever as if it were a max-RPM constant. Client-visible: FIXED: tags
on .../MaxRpm must be re-pointed.
- The spindle read no longer stops at the first zero after slot 1 (which dropped
an idle second spindle and kept non-zero residue); every slot is returned.
A record whose envelope is undescribable (base not 2/10, exponent > 18 -- e.g.
residue past the configured axis/spindle count) publishes BadNoData, never a Good 0.
Ported from the sister ignitionoee FOCAS driver v0.17.2/v0.17.3 (Focas.Wire-019);
live captures live-spmeter-{load,maxrpm}-0x0040.bin added as fixtures.
Every 0x0026 position block is self-describing: [i32 raw][u16 base][u16 exponent],
value = raw / base^exponent. The live 31i-B capture (ref-dynamic2-axis1.bin)
reports base 10 / exponent 4 on every block, so axis 1 is 280.1574 mm, not
2801574. The driver ignored the envelope and instead sent 'cnc_getfigure'
(0x00D3) -- a command that does not exist in the FOCAS wire protocol, served only
by the in-tree mock; the real control refuses it with rc=1, so on hardware every
position fell back to PositionDecimalPlaces (default 0) and published raw counts.
- ParsePositionBlock decodes the envelope into FocasPosition; the driver applies
raw / base^exponent at publish. PositionDecimalPlaces is now only the fallback
for a scale-less (4-byte) block.
- A block describing no position (0xFFFF vacant marker, base not 2/10, exponent
> 18 -- raw / 10^400 would read as a Good 0.0) publishes BadNoData on that node
alone; siblings are untouched.
- ReadPositionFiguresAsync / IFocasClient.GetPositionFiguresAsync and the
per-axis figure cache are deleted.
Ported from the sister ignitionoee FOCAS driver v0.17.0 (+ Focas.Wire-014);
live axis-scoped captures live-dynamic2-axis{1,2}-0x0026.bin (Z-34184 X 0.0374,
Y 370.177) added as fixtures.
Add IFocasClientFactory.EnsureUsable() — a config-time probe called by
FocasDriver.InitializeAsync before any background loops start. The
UnimplementedFocasClientFactory throws NotSupportedException immediately
(faulting the driver at init), eliminating the footgun where a driver on
the 'unimplemented' backend appeared Healthy then failed every read/write/
subscribe silently. WireFocasClientFactory and FakeFocasClientFactory are
no-ops. Backstop Create() throw remains in place.
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.
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.
