 | ISS-032 | 2026-10-01 | ACCESS (OPC UA server node IDs) | IM 36K10L45 §10.3 shows CI Server node IDs (`{"nsid":"32"}`, `{"0":"Value","itnm":"ITEM1"}`) and the CI Server namespace `http://www.yokogawa.com/CI_Server/` (ns 3) but not which namespace the **entities** use. With that URI (or `urn:<host>:Yokogawa:CI_SERVER_OPC_UA_SERVER`) the client point was silently not monitored. Browsing (`OPCUAC_TAG_DF`) shows sections/items in **`urn:Yokogawa:CI_SERVER_OPC_UA_SERVER`**; with it `{"0":"Value","itnm":"<item>"}` and `{"0":"Value","nsid":"<n>"}` both work. IM 36K10E20 §2.2.6 also asks to enable `OPXUAS_USE_NAME_NODEIDS` and restart for CI client ↔ CI server; not needed on the test system. | closed | Closed 2026-10-01 (user decision: installed software is the reference).

 | ISS-033 | 2026-10-01 | ACCESS (Engineering Module OPC UA point) | Tested by the user: the point form's *Browse path* stops at the item (`Objects/CI-Eng-Sample/TANK1/INFLOW`) and stores the item **object** `{"nsid":"548"}`; the point is not monitored (revised sampling interval 0, connected item status 13, *Last value*/*Data type* empty). Typing `{"0":"Value","itnm":"CI-Eng-Sample.TANK1.INFLOW"}` in *Node Id* fixed it (values followed at once). Browsing into an item that is OPC visible but not *Read* fails (`UncertainNotAllNodesAvailable`, `OPXC-E-BRW_NODE`). | open | Answered 2026-10-01 by the user: the browse dialog can expand the item; picking `…/LEVEL/Value` stored `{"0":"Value","nsid":"713"}` with *Last value* 85, *Data type* Double. So: pick the `Value` node, not the item. The `itnm` form stays the choice for quick load (`nsid` changes on reload).

 | ISS-034 | 2026-10-01 | ACCESS (OPC UA server setup) | Installed vs IM 36K10L45 §10.5–10.6: `ServerConfig.xml` enables certificate user tokens (`EnableCertificate true`, manual false) and offers no `None` endpoint (only Basic256Sha256 / Aes128_Sha256_RsaOaep / Aes256_Sha256_RsaPss with Sign or SignAndEncrypt); the `rejected` folder is created only at the first rejection; `opxuas.sup` uses `OPXUAS_DYNAMIC_SCANRATE` (manual `OPXUAS_USE_DYNAMIC_SCANRATE`) and has `OPXUAS_SET_HIGH_PRIO_15` (not described); `opxsys.sup` has `OPXDAS_SET_LOG_LEVEL` (not described).

-| ISS-035 | 2026-10-01 | ALARM (`ALDPRT`) | `ALDPRT` is running and connected (`almdbg` 1 shows `Events-send-to` rising with each alarm), `aldprt.sup` sets no log destination (so per IM 36K10L15 §4.3 it should log via UMH) and `EVENTS` includes `alarm`/`ackn`, but no alarm line appears in `tls\log\umhlog.log` for the CI-Eng-Sample HIGH / HIGH HIGH / acknowledge events. No other log file changed. Cause unknown (UMH filtering? output only with `LOGUMH` set explicitly?). | open | Ask the user whether alarm lines were ever seen in the message log; possibly test `LOGUMH` (or `LOGSCN`) in `aldprt.sup` (admin, restart) in a later session.

No other log file changed. Cause unknown (UMH filtering? output only with `LOGUMH` set explicitly?). | open | Rechecked 2026-10-01 after a restart: `aldprt.exe` runs; `umhlog.log` still has no alarm lines for the new `TANK1.LEVEL` HIGH alarm (only `ALD-I-ALDPRT_EXIT` at each licence shutdown). `fmfprt.sup` assigns printer function `ALARMS` to `ALDPRT`; destination `ALARMS` (policy *Automatic*) has **no device**, and `PRINTER_JOB_OVV` has no `ALDPRT` jobs. The `aldprt.sup` help says UMH is used only when no destination is enabled — the printer function may count as one. Next: test `LOGUMH` in `aldprt.sup` (admin, restart).

 | ISS-036 | 2026-10-01 | ALARM (setup) | Installed vs manuals: `alh.sup` has `DB-JRNL = WAL` and `DB-SYNC = OFF`, not described in IM 36K10L15 §3.4; storage group `ALH` has lifetime **52 weeks** while IM 36K10C20 §A7 says the default is 2 days (may have been changed on this system earlier — unknown); `aldprt.sup` uses `TIMEFMT` where the manual text also writes `TIMFMT`. | closed | Installed software is the reference (standing user decision).

 | ISS-037 | 2026-10-01 | ALARM (history fields) | `ALARM_CHRONO` records contain leftover or unreadable text: INFO events generated with `almdbg` 16 carry `INSTALL`/`UNIT`/`TAG`/`SUB` values from earlier events and non-ASCII bytes in `SOURCE`, `CATEGORY`, `CONDITION`; item events of `CI-Eng-Sample.TANK1.LEVEL` show `SUB` = `RoC` although the item has only the sub-item `MAX`. | open | Rechecked 2026-10-01 after a restart: a new HIGH alarm on `CI-Eng-Sample.TANK1.LEVEL` (raised with `itmval -p`) gave a clean `ALARM_CHRONO` record (`INSTALL`/`UNIT`/`TAG` correct, `SUB` empty, `SOURCE`/`CATEGORY`/`CONDITION` empty), and the user's Current Alarm Overview showed correct columns. The leftover/garbled values are limited to the older records (INFO events made with the `almdbg` 16 test function and events from that session). Documented: treat `SUB`/`SOURCE`/`CATEGORY`/`CONDITION` as reliable only for normal item and OPC events. Ready to close. | `.claude/skills/alarm-management/tasks/alarm-checks.md` §4 |
 | ISS-038 | 2026-10-01 | HISTORY (`ithloahis` + rollover) | An `ithloahis` sample that was dropped (dated 11:50, before the active unit) still became the **initial value** of the next unit: after a forced rollover at 12:05:26 `ITEM_HISTORY` shows `CI-Eng-Sample.TANK1.INFLOW` = 95 (`INITIAL_VALUE` 1) although the item's value was 112. History after loading old samples can therefore show a wrong value at the next rollover. | open | Retested 2026-10-01 after a CI Server restart (first unit 18:05:46). (a) Sample dated one day earlier (95), live value 112, forced rollover: initial value 112 — correct. (b) Sample dated 18:00 (96, a few minutes before the first unit), live value 113, forced rollover: initial value **96** — wrong again; the live item value stayed 113. So a dropped sample dated shortly before the first unit (same day) becomes the next unit's initial value; a much older one did not. Also found: a forced rollover within 2 minutes of the previous one is refused (`DSI-E-ROLLDONE`). Documented as a caution; behaviour confirmed, ready to close. | `.claude/skills/system-management/tasks/load-history.md`; `knowledge/manuals/IM36K10C40-01EN.md` §3 |
