Final two of the five driver test clients. Pattern carried forward from
#249 (Modbus) + #250 (AB CIP, AB Legacy) — each CLI inherits Driver.Cli.Common
for DriverCommandBase + SnapshotFormatter and adds a protocol-specific
CommandBase + 4 commands (probe / read / write / subscribe).
New projects:
- src/ZB.MOM.WW.OtOpcUa.Driver.S7.Cli/ — otopcua-s7-cli.
S7CommandBase carries host/port/cpu/rack/slot/timeout. Handles all S7
atomic types (Bool, Byte, Int16..UInt64, Float32/64, String, DateTime).
DateTime parses via RoundtripKind so "2026-04-21T12:34:56Z" works.
- src/ZB.MOM.WW.OtOpcUa.Driver.TwinCAT.Cli/ — otopcua-twincat-cli.
TwinCATCommandBase carries ams-net-id + ams-port + --poll-only toggle
(flips UseNativeNotifications=false). Covers the full IEC 61131-3
atomic set: Bool, SInt/USInt, Int/UInt, DInt/UDInt, LInt/ULInt, Real,
LReal, String, WString, Time/Date/DateTime/TimeOfDay. Structure writes
refused as out-of-scope (same as AB CIP). IEC time/date variants marshal
as UDINT on the wire per IEC spec. Subscribe banner announces "ADS
notification" vs "polling" so the mechanism is obvious in bug reports.
Tests (49 new, 122 cumulative driver-CLI):
- S7: 22 tests. Every S7DataType has a happy-path + bounds case. DateTime
round-trips an ISO-8601 string. Tag-name synthesis round-trips every
S7 address form (DB / M / I / Q, bit/word/dword, strings).
- TwinCAT: 27 tests. Full IEC type matrix including WString UTF-8 pass-
through + the four IEC time/date variants landing on UDINT. Structure
rejection case. Tag-name synthesis for Program scope, GVL scope, nested
UDT members, and array elements.
Docs:
- docs/Driver.S7.Cli.md — address grammar cheat sheet + the PUT/GET-must-
be-enabled gotcha every S7-1200/1500 operator hits.
- docs/Driver.TwinCAT.Cli.md — AMS router prerequisite (XAR / standalone
Router NuGet / remote AMS route) + per-command examples.
Wiring:
- ZB.MOM.WW.OtOpcUa.slnx grew 4 entries (2 src + 2 tests).
Full-solution build clean. Both --help outputs verified end-to-end.
Driver CLI suite complete: 5 CLIs (otopcua-{modbus,abcip,ablegacy,s7,twincat}-cli)
sharing a common base + formatter. 122 CLI tests cumulative. Every driver family
shipped in v2 now has a shell-level ad-hoc validation tool.
