Second + third of the four driver test clients. Both follow the same shape as otopcua-modbus-cli (#249) and consume Driver.Cli.Common for DriverCommandBase + SnapshotFormatter. New projects: - src/ZB.MOM.WW.OtOpcUa.Driver.AbCip.Cli/ — otopcua-abcip-cli. AbCipCommandBase carries gateway (ab://host[:port]/cip-path) + family (ControlLogix/CompactLogix/Micro800/GuardLogix) + timeout. Commands: probe, read, write, subscribe. Value parser covers every AbCipDataType atomic type (Bool, SInt..LInt, USInt..ULInt, Real, LReal, String, Dt); Structure writes refused as out-of-scope for the CLI. - src/ZB.MOM.WW.OtOpcUa.Driver.AbLegacy.Cli/ — otopcua-ablegacy-cli. AbLegacyCommandBase carries gateway + plc-type (Slc500/MicroLogix/Plc5/ LogixPccc) + timeout. Commands: probe (default address N7:0), read, write, subscribe. Value parser covers Bit, Int, Long, Float, AnalogInt, String, and the three sub-element types (TimerElement / CounterElement / ControlElement all land on int32 at the wire). Tests (35 new, 73 cumulative across the driver CLI family): - AB CIP: 17 tests — ParseValue happy-paths for every Logix atomic type, failure cases (non-numeric / bool garbage), tag-name synthesis. - AB Legacy: 18 tests — ParseValue coverage (Bit / Int / AnalogInt / Long / Float / String / sub-elements), PCCC address round-trip in tag names including bit-within-word + sub-element syntax. Docs: - docs/Driver.AbCip.Cli.md — family ↔ CIP-path cheat sheet + examples per command + typical workflows. - docs/Driver.AbLegacy.Cli.md — PCCC address primer (file letters → CLI --type) + known ab_server upstream gap cross-ref to #224 close-out. Wiring: - ZB.MOM.WW.OtOpcUa.slnx grew 4 entries (2 src + 2 tests). Full-solution build clean. `otopcua-abcip-cli --help` + `otopcua-ablegacy-cli --help` verified end-to-end. Next up (#251): S7 + TwinCAT CLIs, same pattern. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
