Item and station names such as AID.* come from the author's own test project on the development system (see "Test system" in progress.md); they do not exist on other systems.

How to close an issue

1. Confirm the answer with the user (practiced on the test system where possible).
2. Update every file in the issue's "Update on close" column with the answer.
3. Update the matching row in knowledge/progress.md (status and notes).
4. Set the issue to closed and write the resolution and date in "Next step / resolution". Keep closed issues in the table as history.

ISS-001	2026-09-30	ITEM (itmval)	Writing an item with itmval -p -n AID.WRPS.SIM.INFLOW -v 400 added the uoff option flag (options 0x…8a → 0x…8e). The flag stayed after writing the original value back. Meaning of uoff unknown; not found in the EN manuals by text search.	open	2026-09-30: writing internal sample items (CI-Eng-Sample.*, no station) does not set uoff (options stay 0x…88), so it is tied to station-connected items (the AID item was already off, its station not communicating). Still to find: meaning and how to clear it (ITEM Service IM 36K10L35/L36, Engineering Module I/O Processes IM 36K10C10). Revisit in phase 5 with a station item. 2026-09-30 later: unblocking a sample item left the flag ublk (after blk was cleared), so u… flags may mean "was …" (un-blocked / un-offline). Still unconfirmed.	.claude/skills/system-management/tasks/read-write-item.md (replace the uoff note under "Read the current value"); knowledge/progress.md row "Write an item with itmval -p"
ISS-002	2026-09-30	DATABASE (dsschk)	dsschk -d ITEM_DF -v (check only) exits 0 with no console output and nothing new in umhlog.log. Where results are reported is unknown.	closed	Closed 2026-09-30 (confirmed by user). 2026-09-30: dsschk -e -v prints a start/end line per dataset (228 checked, no problems) and logs to umhlog.log. Plain dsschk only compares copies between nodes, so it prints nothing on a single-node system. ismchk needs a database file name (usage: ismchk data_base_name), not run yet.	Create .claude/skills/system-management/tasks/consistency-check.md and add it to that skill's SKILL.md; knowledge/manuals/IM36K10J10-01EN.md §4.1.1 consistency tools (add where output goes); knowledge/progress.md row "Consistency check"
ISS-003	2026-09-30	DATABASE (dssqld)	Filtered export (dssqld -e <out> <filter>.qli) failed with a guessed filter syntax (@ITEM_DF, @FIELD, @SELECT).	closed	Closed 2026-09-30 (confirmed by user). 2026-09-30: the quick load data format is now known and verified (@LANGUAGE, @VERSION, @FIELDS, @<DATASET>, quoted CSV records, \ continuation, ! comments; IM 36K10L45 §9.11). Filter syntax found (IM 36K10L50 §3.6) and practiced, awaiting confirmation: a file with @SELECT, then the filter in single quotes (strings in double quotes), then @<DATASET>; run dssqld -e <out> <filter>.qli. ITEM_HISTORY returns nothing unless the filter names ITEM_NAME and a SAMPLE_TIME range (SAMPLE_TIME > "dd-mm-yyyy hh:mm:ss" and SAMPLE_TIME < ...).	.claude/skills/system-management/tasks/export-dataset.md section "Filtered exports"; knowledge/manuals/IM36K10J10-01EN.md §5.6 step 1; knowledge/progress.md row "Export a dataset"
ISS-004	2026-09-30	ITEM (itmval)	itmval -g -a <1..5> returns ITM-E-WRONG_ATT on AID.WRPS.* items, so reading limits is unproven.	closed	Closed 2026-09-30 (confirmed by user). On CI-Eng-Sample.TANK1.LEVEL (limits set) -a 1..5 returned deadband 0, low 20, high 80, low-low 10, high-high 90. The error only occurs on items without limits.	.claude/skills/system-management/tasks/read-write-item.md (limits section); knowledge/progress.md row "Read an item with itmval -g"
ISS-005	2026-09-30	DATABASE (dssqld)	Loading 04_item_his_df.qli straight after creating the storage group gave 2 errors once; three other runs were clean. Error text not captured.	open	Added a 5 s pause in load.cmd. If it happens again, capture 04_item_his_df.qlo.	examples/CI-Eng-Sample/load.cmd; .claude/skills/system-management/tasks/load-remove-records.md
ISS-006	2026-09-30	HISTORY (ithloahis)	Samples dated before the start of the current storage unit were not stored (no error shown); samples after it were. Also, a new storage group stored nothing until CI Server was restarted.	open	Confirm with History Management (IM 36K10L20) in phase 9: how to load into older units, and whether a restart is really required.	.claude/skills/system-management/tasks/load-history.md; examples/CI-Eng-Sample/README.md; knowledge/manuals/IM36K10J10-01EN.md command-line tools
ISS-007	2026-09-30	INTEGRATION (monitoring)	intdskmon wrote 61.9 for a C: drive that is 61.9 % used / 38.1 % free, although the manual says it monitors the disk free space rate. intspawn did nothing when the command path was ~130 characters; a short path worked (limit unknown).	open	Confirm the disk value meaning and the path limit.	.claude/skills/system-management/tasks/monitoring-processes.md; knowledge/manuals/IM36K10J10-01EN.md §4.1.6; examples/CI-Eng-Sample/monitoring/
ISS-008	2026-09-30	ACCESS (web/OPC UA server?)	ci_start.log on the test system shows CppServerAPI::Run() failed: InitializeSslCtx(): SSL_CTX_use_certificate_chain_file() failed. right after ACCESS Service starts. Which component and certificate is not known.	open	Identify in phase 7 (OPC Interface IM 36K10E20, Data Access IM 36K10L45).	.claude/skills/installation-security/tasks/setup-check.md; the phase 7 skill
ISS-009	2026-09-30	Security Guide	DCOM port range printed as 20500–20550 in the firewall table but "2500–20550" in the OPC configuration table. Taken as a typo for 20500–20550.	open	Confirm on a system with IT security applied.	knowledge/manuals/IM36K01C30-01EN.md §4

| ISS-010 | 2026-09-30 | ITEM (sub-items) | The Integrator sub-item adds value × seconds; setting TIME_UNIT = Hour made no difference (1 per second while the main item was 1).

The repo uses wfla_display.sup. | knowledge/manuals/IM36K10R10-01EN.md §4; .claude/skills/portal-setup/tasks/read-setup-file.md | | ISS-013 | 2026-09-30 | CI Portal setup files | Installed values differ from the defaults stated in IM 36K10R10 §4.4: wfla_display.sup DUR_QUEUE_SIZE = 1000 (manual 500 kB); wflgdi.sup DUR_QUEUE_SIZE = 252 (manual 1000 kB); wfla_display.sup and wflcdi.sup set TIMER_INTERVAL = 10 (manual: 1 s when not set). | closed | Closed 2026-09-30 (user decision: the installed software and files are the reference). The repo quotes the installed values as defaults. | knowledge/manuals/IM36K10R10-01EN.md §4 | | ISS-014 | 2026-09-30 | CI Portal setup files | jwuiisg.sup has a Security tab (SECURITY_ENABLED, CORS_ENTRY, HEADER_ENTRY) that IM 36K10R10 §4.3 does not describe. | closed | Closed 2026-09-30 (user decision: the installed software and files are the reference). Documented from the file's own !KEYWORD/!HELP text. Installed CORS allows all origins (allowedOrigins "*"); tightening it is a site security decision. | knowledge/manuals/IM36K10R10-01EN.md §4.3 | | ISS-015 | 2026-09-30 | Setup File Editor | In wfla_display.sup the seven main keywords (RELATION_LOCATION … TIMER_INTERVAL) come before the only tab line !TAB = Debug. By IM 36K10R20 §3.1, keywords before the first !TAB are not shown, yet IM 36K10R10 §4.4.1 shows them on a General tab. What the editor really shows is unknown. | closed | Closed 2026-09-30 (checked in the Setup File Editor by the user; installed software is the reference). The editor shows keywords placed before the first !TAB on a General tab, followed by the defined tabs: wfla_display.sup shows General (all 7 fields, values as in the file) and Debug. The manual's statement that such keywords are ignored does not hold in R1.03. | knowledge/manuals/IM36K10R20-01EN.md §3; knowledge/manuals/IM36K10R10-01EN.md §4; .claude/skills/portal-setup/tasks/change-setup-file.md | | ISS-016 | 2026-09-30 | Setup File Editor | The R1.03 editor has features IM 36K10R20 §2 does not describe: a Templates tab next to Setup Files; a Status column in the file list (e.g. "Default"); Undo Field and Reset Field buttons on the edit form besides OK/Cancel/Help; a status bar with the selected file's description and the time. | open | Installed software is the reference (user decision). 2026-09-30, tested on wfla_display.sup (DUR_QUEUE_SIZE 1000 → 2000): clicking OK writes the file immediately (only the active line changed; the manual says OK keeps the change in memory until Exit). Status becomes Changed when an active value differs from the file's !DEFAULT block; the changed field's label turns blue. Reset Field is enabled when the cursor is in a changed field; Reset Field + OK put the value back to the !DEFAULT value (2000 → 1000) and wrote the file at once (16:22:28); the rest of the file was unchanged. Still to find: what Templates holds and what Undo Field does. | knowledge/manuals/IM36K10R20-01EN.md §2; .claude/skills/portal-setup/tasks/change-setup-file.md | | ISS-017 | 2026-09-30 | CI Portal setup files | IM 36K10R10 §4 says the logon method is the one user-interface setting normally changed, but the R1.03 jwuiisg.sup Information tab says the login method and login control settings have moved to dssana.sup (authentication and authorization). dssana.sup is not described in R10. | open | Installed software is the reference. 2026-09-30: dssana.sup ("Authentication and authorization setup") has tabs General, User Interfaces, Clients System Trust, Login control (LOGIN_METHOD = <client>, <user interface>, <method>, …), Active Directory, Single Sign On, Password rules, Logging.
