# Item engineering (R1.03)

Background: `knowledge/manuals/IM36K10G10-01EN.md` (chapter 3). Bulk creation of sections and
items uses quick load files: skill `system-management`, task `load-remove-records.md`.
Reading and writing values: `system-management` task `read-write-item.md`.

Rules:
- Run the `system-check` skill first; follow the user's chosen way of working for any change.
- Names: `Section.Sub-section.Item`, max 255 bytes, no `:` or `.` inside a name, case insensitive.

| Task | File | Status |
|---|---|---|
| Sub-items (integrator, min-max) | `tasks/sub-items.md` | verified |
| Block / unblock an item; write to a blocked item | `tasks/block-item.md` | verified |
| String items: length limit (1–200) and truncation | `tasks/string-items.md` | verified |
| Item forms, limits, PIT filter, clamping, alarm tab, option bits, item statuses | `knowledge/manuals/IM36K10C10-01EN.md` §3–4 | from docs |
| Switch on alarming, ack type, delay/repeat, test and acknowledge alarms | skill `alarm-management`, task `item-alarming.md` | verified |
