Add IDriverControl capability interface in Core.Abstractions with a
RebrowseAsync(IAddressSpaceBuilder, CancellationToken) hook so operators
can force a controller-side @tags re-walk without restarting the driver.
AbCipDriver now implements IDriverControl. RebrowseAsync clears the UDT
template cache (so stale shapes from a pre-download program don't
survive) then runs the same enumerator + builder fan-out as
DiscoverAsync, serialised against concurrent discovery / rebrowse via
a new SemaphoreSlim.
Driver.AbCip.Cli ships a `rebrowse` subcommand mirroring the existing
probe / read shape: connects to a single gateway, runs RebrowseAsync
against an in-memory builder, and prints discovered tag names so
operators can sanity-check the controller's symbol table from a shell.
Tests cover: two consecutive RebrowseAsync calls bump the enumerator's
Create / Enumerate counters once each, discovered tags reach the
supplied builder, the template cache is dropped on rebrowse, and the
driver exposes IDriverControl. 313 AbCip unit tests + 17 CLI tests +
37 Core.Abstractions tests pass.
Closes#233
CsvTagImporter / CsvTagExporter parse and emit Kepware-format AB CIP tag
CSVs (Tag Name, Address, Data Type, Respect Data Type, Client Access,
Scan Rate, Description, Scaling). Import maps Tag Name → AbCipTagDefinition.Name,
Address → TagPath, Data Type → DataType, Description → Description,
Client Access → Writable. Skips blank rows + ;/# section markers; honours
column reordering via header lookup; RFC-4180-ish quoting.
CsvImports collection on AbCipDriverOptions mirrors L5kImports/L5xImports
and is consumed by InitializeAsync (declared > L5K > L5X > CSV precedence).
CLI tag-export command dumps the merged tag table from a driver-options JSON
to a Kepware CSV — runs the same import-merge precedence the driver uses but
without contacting any PLC.
Tests cover R/W mapping, blank-row skip, quoted comma, escaped quote, name
prefix, unknown-type fall-through, header reordering, and a load → export →
reparse round-trip.
Closes#232
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.
