Feature/dope 442 unified modbus config - #1025
Conversation
WalkthroughThe PR adds unified Modbus RTU and TCP-link configuration models, migration utilities, normalized project updates, target capability gating, editor controls, and compiler and device-link integration. Legacy vendor screen data remains supported through fallback conversion. ChangesUnified Modbus configuration
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This PR centralizes Modbus configuration and changes the data used for firmware generation and device connection, but malformed legacy settings and invalid slave IDs can produce incorrect device behavior, while the new controls are inaccessible to assistive technology. These issues should be addressed before merging. Sequence Diagram(s)sequenceDiagram

1726-1734: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low valueSpreading the patch can reset a field to its default.
The doc comment on
resolveModbusRtuinsrc/frontend/utils/modbus/serial-link-config.ts(lines 154-159) states the reason it avoids a spread: a key that is explicitlyundefinedoverwrites the value it merges onto. This call site reintroduces that spread.updateServerConfigacceptsPartial<ModbusRtuConfig>, so a caller can pass{ slaveId: undefined }. The existingslaveIdis then replaced byundefined, and the resolver substitutes the default rather than keeping the saved value.No current caller does this, so the effect is latent. Dropping undefined keys before the merge makes the action match the resolver contract.

Restrict slaveId to valid Modbus RTU values.
z.number() accepts 0, 248, and fractional values. The shared ModbusRtuConfig contract specifies IDs from 1 through 247. Invalid project data can pass schema validation and reach firmware generation and device connection.

No control in these sections exposes an accessible name. Row renders Label as a sibling of the control with no htmlFor, and no row component gives its control an id or an aria-label. Every checkbox, select and text input in the Serial Slave and Network Link sections therefore reaches assistive technology unnamed. One fix at the row helpers covers all fifteen controls.

Replace the non-null assertions in the new assertions.
Lines 1960, 1976, 1986 and 1997 use ! on servers, modbusSlaveConfig and rtu. The coding guidelines forbid non-null assertions in src/**/*.{ts,tsx}. Narrow explicitly instead, which also produces a clearer failure when the server is missing.
♻️ Example for one site
- const config = store.getState().project.data.servers![0].modbusSlaveConfig!
+ const config = store.getState().project.data.servers?.[0]?.modbusSlaveConfig
+ expect(config).toBeDefined()
expect(config.rtu).toEqual({Assign the narrowed value to a local after the expect(...).toBeDefined() check, or use assert/a small helper that throws, so the type is non-optional afterwards.
As per coding guidelines: "Do not use non-null assertions (!); handle undefined values or narrow explicitly."

Description of the changes proposed
The ticket asks for one Modbus screen. There are two, and which one you get
depends on the board: bare-metal targets get a screen that isn't in this repo at
all — it's declared in
openplc-packagesasscreens/modbus.jsonand renderedby the generic vendor-screen renderer under
Device > Modbus— while runtimetargets get the editor's own screen under
Servers > modbus_slave.What makes this more than a UI move: the package screen wasn't decorative. What
it persisted feeds two things — the
defines.hthat compiles into thefirmware (
MBSERIAL_*,MBTCP_*) and the baud and slave id the editor dialsto reach the board on Connect. So unifying the screen means moving where that
data comes from, on a path where a mistake is silent: a wrong baud opens the port
to nothing, which Connect reports as "No Firmware Detected" on a healthy board.

Decisions worth flagging in review

That drops the only irreversible step the plan had, along with the question of

comparing outputs, which is what the suite does.

ethernet shield, and that server is now where their configuration lives.
Leaving it false meant switching to an Arduino target warned that the
project's servers were unsupported, about the one screen the target needs
most. A test that pinned the old value was rewritten with the reasoning.
