What

• mbmap 2.1.0
  • identify (FC17/FC43) is read, validated (bad-identify), written back and used by Check device (app and CLI) to compare model and firmware. Registers with a role take priority.
  • read_alone / read_group are validated (bad-read) and honoured by the read planner (poller, Node-RED export).
  • The 2.1 samples in mbmap-library/tests give the errors listed in its expected.json.
• Vendor icons: fall back to DuckDuckGo/Google favicon services when a vendor site refuses automated requests, as the mbmap site does. This sends the vendor domain to those services.
• README: new compatible-.mbmap badge; Russian translation (docs/readme/README_RU.md) and language switcher entries.
• vendor/mbmap-library updated to the latest main.
• Simulator test: the map used as "no identity registers" now has one, so it uses abb/acs355.

Known limitation

FC17 answers whose run-indicator byte is not 0x00/0xFF are rejected by tokio-modbus, so the check is "unknown" for those devices (e.g. Lovato DMG610). FC43 is complete. Needs a small patch to tokio-modbus to fix.

Not done

The map builder UI has no fields for identify, read_alone or read_group yet (TS types only).

Tests

cargo test, cargo clippy --all-targets -- -D warnings, npm run check and npm test pass.
