# FOCAS version / capability matrix
|
|
|
|
Authoritative source for the per-CNC-series ranges that
|
|
[`FocasCapabilityMatrix`](../../src/ZB.MOM.WW.OtOpcUa.Driver.FOCAS/FocasCapabilityMatrix.cs)
|
|
enforces at driver init time. Every row cites the Fanuc FOCAS Developer
|
|
Kit function whose documented input range determines the ceiling.
|
|
|
|
**Why this exists** — we have no FOCAS hardware on the bench and no
|
|
working simulator. Fwlib32 returns `EW_NUMBER` / `EW_PARAM` when you
|
|
hand it an address outside the controller's supported range; the
|
|
driver would map that to a per-read `BadOutOfRange` at steady state.
|
|
Catching at `InitializeAsync` with this matrix surfaces operator
|
|
typos + mismatched series declarations as config errors before any
|
|
session is opened, which is the only feedback loop available without
|
|
a live CNC to read against.
|
|
|
|
**Who declares the series** — `FocasDeviceOptions.Series` in
|
|
`appsettings.json`. Defaults to `Unknown`, which is permissive — every
|
|
address passes validation. Pre-matrix configs don't break on upgrade.

## Series covered
|
|
|
|
| Enum value | Controller family | Typical era |
|
|
| --- | --- | --- |
|
|
| `Unknown` | (legacy / not declared) | permissive fallback |
|
|
| `Sixteen_i` | 16i / 18i / 21i | 1997-2008 |
|
|
| `Zero_i_D` | 0i-D | 2008-2013 |
|
|
| `Zero_i_F` | 0i-F | 2013-present, general-purpose |
|
|
| `Zero_i_MF` | 0i-MF | 0i-F lathe variant |
|
|
| `Zero_i_TF` | 0i-TF | 0i-F turning variant |
|
|
| `Thirty_i` | 30i-A / 30i-B | 2007-present, high-end |
|
|
| `ThirtyOne_i` | 31i-A / 31i-B | 30i simpler variant |
|
|
| `ThirtyTwo_i` | 32i-A / 32i-B | 30i compact |
|
|
| `PowerMotion_i` | Power Motion i-A / i-MODEL A | motion-only controller |
|
|
|
|
## Macro variable range (`cnc_rdmacro` / `cnc_wrmacro`)
|
|
|
|
Common macros `1-33` + `100-199` + `500-999` are universal across all
|
|
series. Extended macros (`#10000+`) exist only on higher-end series.
|
|
The numbers below reflect the extended ceiling per series per the
|
|
DevKit range tables.
|
|
|
|
| Series | Min | Max | Notes |
|
|
| --- | ---: | ---: | --- |
|
|
| `Sixteen_i` | 0 | 999 | legacy ceiling — no extended |
|
|
| `Zero_i_D` | 0 | 999 | 0i-D still at legacy ceiling |
|
|
| `Zero_i_F` / `Zero_i_MF` / `Zero_i_TF` | 0 | 9999 | extended added on 0i-F |
|
|
| `Thirty_i` / `ThirtyOne_i` / `ThirtyTwo_i` | 0 | 99999 | full extended set |
|
|
| `PowerMotion_i` | 0 | 999 | atypical — limited macro coverage |
|
|
|
|
## Parameter range (`cnc_rdparam` / `cnc_wrparam`)
|
|
|
|
| Series | Min | Max |
|
|
| --- | ---: | ---: |
|
|
| `Sixteen_i` | 0 | 9999 |
|
|
| `Zero_i_D` / `Zero_i_F` / `Zero_i_MF` / `Zero_i_TF` | 0 | 14999 |
|
|
| `Thirty_i` / `ThirtyOne_i` / `ThirtyTwo_i` | 0 | 29999 |
|
|
| `PowerMotion_i` | 0 | 29999 |
|
|
|
|
## PMC letters (`pmc_rdpmcrng` / `pmc_wrpmcrng`)
|
|
|
|
Addresses are letter + number (e.g. `R100`, `F50.3`). Legacy
|
|
controllers omit the `F`/`G` signal groups that 30i-family ladder
|
|
programs use, and only the 30i-family exposes `K` (keep-relay) +
|
|
`T` (timer).
|
|
|
|
| Letter | 16i | 0i-D | 0i-F family | 30i family | Power Motion-i |
|
|
| --- | :-: | :-: | :-: | :-: | :-: |
|
|
| `X` | yes | yes | yes | yes | yes |
|
|
| `Y` | yes | yes | yes | yes | yes |
|
|
| `R` | yes | yes | yes | yes | yes |
|
|
| `D` | yes | yes | yes | yes | yes |
|
|
| `E` | — | yes | yes | yes | — |
|
|
| `A` | — | yes | yes | yes | — |
|
|
| `F` | — | — | yes | yes | — |
|
|
| `G` | — | — | yes | yes | — |
|
|
| `M` | — | — | yes | yes | — |
|
|
| `C` | — | — | yes | yes | — |
|
|
| `K` | — | — | — | yes | — |
|
|
| `T` | — | — | — | yes | — |
|
|
|
|
Letter match is case-insensitive. `FocasAddress.PmcLetter` is carried
|
|
as a string (not char) so the matrix can do ordinal-ignore-case
|
|
comparison.
|
|
|
|
## PMC address-number ceiling
|
|
|
|
PMC addresses are byte-addressed on read + bit-addressed on write;
|
|
`FocasAddress` carries the bit index separately, so these are byte
|
|
ceilings.
|
|
|
|
| Series | Max byte | Notes |
|
|
| --- | ---: | --- |
|
|
| `Sixteen_i` | 999 | legacy |
|
|
| `Zero_i_D` | 1999 | doubled since 16i |
|
|
| `Zero_i_F` family | 9999 | |
|
|
| `Thirty_i` family | 59999 | highest density |
|
|
| `PowerMotion_i` | 1999 | |
|
|
|
|
## Error surface
|
|
|
|
When a tag fails validation, `FocasDriver.InitializeAsync` throws
|
|
`InvalidOperationException` with a message of the form:
|
|
|
|
```
|
|
FOCAS tag '<name>' (<address>) rejected by capability matrix: <reason>
|
|
```
|
|
|
|
`<reason>` is the verbatim string from `FocasCapabilityMatrix.Validate`
|
|
and always names the series + the documented limit so the operator
|
|
can either raise the limit (if wrong) or correct the CNC series they
|
|
declared (if mismatched). Sample:
|
|
|
|
```
|
|
FOCAS tag 'X_axis_macro_ext' (MACRO:50000) rejected by capability
|
|
matrix: Macro variable #50000 is outside the documented range
|
|
[0, 9999] for Zero_i_F.
|
|
```
|
|
|
|
## How this matrix stays honest
|
|
|
|
- Every row is covered by a parameterized test in
|
|
[`FocasCapabilityMatrixTests.cs`](../../tests/ZB.MOM.WW.OtOpcUa.Driver.FOCAS.Tests/FocasCapabilityMatrixTests.cs)
|
|
— 46 cases across macro / parameter / PMC-letter / PMC-number
|
|
boundaries + unknown-series permissiveness + rejection-message
|
|
content + case-insensitivity.
|
|
- Widening or narrowing a range in the matrix without updating this
|
|
doc will fail a test, because the theories cite the specific row
|
|
they reflect in their `InlineData`.
|
|
- The matrix is not comprehensive — it encodes only the subset of
|
|
FOCAS surface the driver currently exposes (Macro / Parameter /
|
|
PMC). When the driver gains a new capability (e.g. tool management,
|
|
alarm history), add its series-specific range tables here + matching
|
|
tests at the same time.
|
|
|
|
## Follow-up
|
|
|
|
This validation closes the cheap half of the FOCAS hardware-free
|
|
stability gap — config errors now fail at load instead of per-read.
|
|
The expensive half is Tier-C process isolation so that a crashing
|
|
`Fwlib32.dll` doesn't take the main OPC UA server down with it. See
|
|
[`docs/v2/implementation/focas-isolation-plan.md`](implementation/focas-isolation-plan.md)
|
|
for that plan (task #220).
