Close corrections-doc E2 (Aveva System Platform IO upstream-OPC-UA pattern verification) with GREEN-YELLOW verdict (decision #141 ) — AVEVA's OI Gateway communication driver is the documented path for AppServer to consume from arbitrary upstream OPC UA servers; multiple AVEVA partners (Software Toolbox, InSource) have published end-to-end integrations against four different non-AVEVA upstream servers (TOP Server, OPC Router, OmniServer, Cogent DataHub). No re-architecting of OtOpcUa required. Path: OPC UA node → OI Gateway → SuiteLink → $DDESuiteLinkDIObject → AppServer attribute. Recommended AppServer floor: System Platform 2023 R2 Patch 01.

mitsubishi.md

Phase 3 PR 55 -- Mitsubishi MELSEC Modbus TCP quirks research document. 451-line doc at docs/v2/mitsubishi.md mirroring the docs/v2/dl205.md template for the MELSEC family (Q-series + QJ71MT91, L-series + LJ71MT91, iQ-R + RJ71EN71, iQ-R built-in Ethernet, iQ-F FX5U built-in, FX3U + FX3U-ENET / FX3U-ENET-P502, FX3GE built-in). Like Siemens S7, MELSEC Modbus is a patchwork of per-site-configured add-on modules rather than a fixed firmware stack, but the MELSEC-specific traps are different enough to warrant their own document. Key findings worth flagging for the PR 58+ implementation track: (1) MODULE NAMING TRAP -- QJ71MB91 is SERIAL RTU, not TCP. The Q-series TCP module is QJ71MT91. Driver docs + config UI should surface this clearly because the confusion costs operators hours when they try to connect to an RS-232 module via Ethernet. (2) NO CANONICAL MAPPING -- every MELSEC Modbus site has a unique 'Modbus Device Assignment Parameter' block of up to 16 assignments (each binding a MELSEC device range like D0..D1023 to a Modbus-address range); the driver must treat the mapping as runtime config, not device-family profile. (3) X/Y BASE DEPENDS ON FAMILY -- Q/L/iQ-R use HEX notation for X/Y (X20 = decimal 32), FX/iQ-F use OCTAL (X20 = decimal 16, same as DL260); iQ-F has a GX Works3 project toggle that can flip this. Single biggest off-by-N source in MELSEC driver code -- driver address helper must take a family selector. (4) Word order CDAB across Q/L/iQ-R/iQ-F by default (CPU-level, not module-level) -- no user-configurable swap on the server side. FX5U's SWAP instruction is for CLIENT mode only. Driver Mitsubishi profile default must be ByteOrder.WordSwap, matching DL260 but OPPOSITE of Siemens S7. (5) D-registers are BINARY by default (opposite of DL205's BCD-by-default). FNC 18 BCD / FNC 19 BIN instructions confirm binary-by-default in the ladder. Caller must explicitly opt-in to Bcd16/Bcd32 tags when the ladder stores BCD, same pattern as DL205 but the default is inverted. (6) FX5U FIRMWARE GATE -- needs firmware >= 1.060 for native Modbus TCP server; older firmware is client-only. Surface a clear capability error on connect. (7) FX3U PORT 502 SPLIT -- the standard FX3U-ENET cannot bind port 502 (lower port range restricted on the firmware); only FX3U-ENET-P502 can. FX3U-ENET-ADP has no Modbus at all and is a common operator mis-purchase -- driver should surface 'module does not support Modbus' as a distinct error, not 'connection refused'. (8) QJ71MT91 does NOT support FC22 (Mask Write) or FC23 (Read-Write Multiple). iQ-R and iQ-F do. Driver bulk-read optimization must gate on module capability. (9) MAX CONNECTIONS -- 16 simultaneous on Q/L/iQ-R, 8 on FX5U and FX3U-ENET. (10) STOP-mode writes -- configurable on Q/L/iQ-R/iQ-F (default = accept writes even in STOP), always rejected with exception 04 on FX3U-ENET. Per-model test differentiation section names the tests Mitsubishi_QJ71MT91_*, Mitsubishi_FX5U_*, Mitsubishi_FX3U_ENET_*, with a shared Mitsubishi_Common_* fixture for CDAB-word-order + binary-not-BCD + standard-exception-codes tests. 17 cited references including primary Mitsubishi manuals (SH-080446 for QJ71MT91, JY997D56101 for FX5, SH-081259 for iQ-R Ethernet, JY997D18101 for FX3U-ENET) plus Ignition / Kepware / Fernhill / HMS third-party driver release notes. Three unconfirmed rumours flagged explicitly: iQ-R RJ71EN71 early firmware rumoured ABCD word order (no primary source), QJ71MT91 firmware < 2010-05 FC15 odd-byte-count truncation (forum report only), FX3U-ENET firmware < 1.14 out-of-order TxId echoes under load (unreproducible on bench). Pure documentation PR -- no code, no tests. Per-quirk implementation lands in PRs 58+. Research conducted 2026-04-18.

s7.md

Phase 3 PR 54 -- Siemens S7 Modbus TCP quirks research document. 485-line doc at docs/v2/s7.md mirroring the docs/v2/dl205.md template for the Siemens SIMATIC S7 family (S7-1200 / S7-1500 / S7-300 / S7-400 / ET 200SP / CP 343-1 / CP 443-1 / CP 343-1 Lean / MODBUSPN). Siemens S7 is fundamentally different from DL260: there is no fixed Modbus memory map baked into firmware -- every deployment runs MB_SERVER (S7-1200/1500/ET 200SP), MODBUSCP (S7-300/400 + CP), or MODBUSPN (S7-300/400 PN) library blocks wired up to user DBs via the MB_HOLD_REG / ADDR parameters. The driver's job is therefore to handle per-site CONFIG rather than per-family QUIRKS, and the doc makes that explicit. Key findings worth flagging for the PR 56+ implementation track: (1) S7 has no fixed memory map -- must accept per-site DriverConfig, cannot assume vendor-standard layout. (2) MB_SERVER requires NON-optimized DBs in TIA Portal; optimized DBs cause the library to return STATUS 0x8383 on every access -- the single most common S7 Modbus deployment bug in the field. (3) Word order is ABCD by default (big-endian bytes + big-endian words) across all Siemens S7 Modbus paths, which is the OPPOSITE of DL260 CDAB -- the Modbus driver's S7 profile default must be ByteOrder.BigEndian, not WordSwap. (4) MB_SERVER listens on ONE port per FB instance; multi-client support requires running MB_SERVER on 502 / 503 / 504 / ... simultaneously -- most clients assume port 502 multiplexes, which is wrong on S7. (5) CP 343-1 Lean is SERVER-ONLY and requires the separate 2XV9450-1MB00 MODBUS TCP CP library license; client mode calls return immediate error on Lean. (6) MB_SERVER does NOT filter Unit ID, accepts any value. Means the driver can't use Unit ID to detect 'direct vs gateway' topology. (7) FC23 Read-Write Multiple, FC22 Mask Write, FC20/21 File Records, FC43 Device Identification all return exception 01 Illegal Function on every S7 variant -- the driver MUST NOT attempt bulk-read optimisation via FC23 when talking to S7. (8) STOP-mode read/write behaviour is non-deterministic across firmware bands: reads may return cached data (library internal buffer), writes may succeed-silently or return exception 04 depending on CPU firmware version -- flagged as 'driver treats both as unavailable, do not distinguish'. Unconfirmed rumours flagged separately: 'V2.0+ reverses float byte order' claim (cited but not reproduced), STOP-mode caching location (folklore, no primary source). Per-model test differentiation section names the tests as S7_<model>_<behavior> matching the DL205 template convention (e.g. S7_1200_MB_SERVER_requires_non_optimized_DB, S7_343_1_Lean_rejects_client_mode, S7_FC23_returns_IllegalFunction). 31 cited references across the Siemens Industry Online Support entry-ID system (68011496 for MB_SERVER FAQ, etc.), TIA Portal library manuals, and three third-party driver vendor release notes (Kepware, Ignition, FactoryTalk). This is a pure documentation PR -- no code, no tests, no csproj changes. Per-quirk implementation lands in PRs 56+. Research conducted 2026-04-18 against latest publicly-available Siemens documentation; STOP-mode behaviour and MB_SERVER versioning specifically cross-checked against Siemens forum answers from 2024-2025.

V1_ARCHIVE_STATUS.md

Phase 2 PR 61 -- Close V1_ARCHIVE_STATUS.md; Phase 2 Streams D + E done. Purely a documentation-closure PR. The v1 archive deletion itself happened across earlier PRs: PR 2 on phase-2-stream-d archive-marked the four v1 projects (IsTestProject=false so dotnet test slnx bypassed them); Phase 3 PR 18 deleted the archived project source trees. What remained on disk was stale bin/obj residue from pre-deletion builds -- git never tracked those, so removing them from the working tree is cosmetic only (no source-file diff in this PR). What this PR actually changes: V1_ARCHIVE_STATUS.md is rewritten from 'Deletion plan (Phase 2 PR 3)' pre-work prose to a CLOSED retrospective that (a) lists all five v1 directories as deleted with check-marks (src/OtOpcUa.Host, src/Historian.Aveva, tests/Historian.Aveva.Tests, tests/Tests.v1Archive, tests/IntegrationTests), (b) names the parity-bar tests that now fill the role the 494 v1 tests originally held (Driver.Galaxy.E2E cross-FX subprocess parity + stability-findings regression, per-component *.Tests projects, Driver.Modbus.IntegrationTests, LiveStack/ smoke tests), and (c) gives the closure timeline connecting PR 2 -> Phase 3 PR 18 -> this PR 61. Also added the Modbus TCP driver family as parity coverage that didn't exist in v1 (DL205 + S7-1500 + Mitsubishi MELSEC via pymodbus sim). Stream D (retire legacy Host) has been effectively done since Phase 3 PR 18; Stream E (parity validation) is done since PR 2 landed the Driver.Galaxy.E2E project with HostSubprocessParityTests + HierarchyParityTests + StabilityFindingsRegressionTests. This PR exists to definitively close the two pending Phase 2 tasks on the task list and give future-me (or anyone picking up Phase 2 retrospectives) a single 'what actually happened' doc instead of a 'what we plan to do' prose that didn't match reality. dotnet build ZB.MOM.WW.OtOpcUa.slnx: 0 errors, 200 warnings (all xunit1051 cancellation-token analyzer advisories, unchanged from v2 tip). No test regressions -- no source code changed.
