# Sweet Grass site guide

Verified through production Configure Pages and native element Copy on 2026-10-21 (America/Edmonton). This was a read-only context survey: no page saves, pastes, register writes, alarm changes, device actions, or operational command tests. Bindings describe the configured UI, not proven PLC behavior. No credentials or camera/map endpoints are retained.

## Identity and coverage

Production: https://www.atomhmi.com/site_sweetgrass/  
Configure: https://www.atomhmi.com/site_sweetgrass/configure_pages

Catalog remains 51 pages. PAGE-INVENTORY.md preserves the full list from October 20. October 21 refreshed the catalog and selected active pages, resolving both previous motor-tree inspection gaps. Combined historical coverage now includes every listed page tree, but this is not an audit of every element's behavior.

## Useful starting pages

| Page | Slug | Roots / element count observed October 21 |
| --- | --- | --- |
| Overview | overview | Main Selection; 49 |
| Center Receiving | center_receiving | Control Row; 228 |
| South Receiving | south_receiving | Control Row; 83 |
| Receiving Sequence | receiving_sequence | Control Row; 100 |
| Crimping | crimping | Control Row; 103 |
| Groater | groater | Control Row; 313 |
| Shipping | shipping | Control Row; 103 |
| dryer | dryer | Dryer Chart Div + Overview Row; 137 |
| Power Main | power_main | Menu + Main Row + Table; 186 |
| Power Dryer | power_dryer | Menu + Main Row + Table; 186 |
| Motors | motors | Motors; 1,435 |
| old Motors | old_motors | Motors; 1,246 |
| Receiving PID Tuning | receiving_pid_tuning | no roots/elements |

Use Overview for compact status cards; Center/South Receiving for routing and sequence controls; Groater for dropdown and equipment control; Shipping for four-state indicators and destination selection; dryer for chart-plus-controls; Power pages for chart/readouts/tables. Empty Receiving PID Tuning is not an established tuning interface.

## Motor tree gap resolved

Motors and old Motors both loaded on October 21. Native Copy exported each whole root; active Motors has 103 direct children and old Motors has 83. These include menu/group structure, so do not interpret the counts as a proven motor count.

Active groups include dryer-style m02_01 through m90 families and other groups named M001, M002, M016, M101, M202, M301, etc. Group names and prefixes differ; inspect each intended unit rather than applying one global rename.

Representative active dryer motor m02_01:
| Function | Configured binding |
| --- | --- |
| Auto/Manual | main:dryer_g_m02_01_in_autoMode; 1/0 |
| Start | main:dryer_g_m02_01_in_manFwd; writes 1 |
| Stop | main:dryer_g_m02_01_in_manStop; writes 1 |
| Hertz display | main:dryer_g_m02_01_out_speedActHz |
| Hertz write target | main:dryer_g_m02_01_in_manSpeedRef; direct value |
| Time since start | main:dryer_g_m02_01_out_tss multiplied by 1000; non-editable HH:mm:ss |

The editable Hertz field intentionally separates actual-speed display from manual demand target. A configured target on the non-editable time display does not authorize writing an output.

For large trees, use the root's direct Copy control rather than resolving every descendant button. Reload a clean Configure Pages session before each large page; accumulated previews caused timeouts during this survey. See ATOMHMI-PLAYBOOK.md.

## Prior verified context retained

The October 20 study in SITE-STUDY.md established:
- Device IDs global (Global) and main (Main PC).
- Main PC slave labels Codesys PLC, Groater PLC, Main PLC, SG Dryer, Shipping PLC, Terminal.
- Page → device-qualified register → slave → PLC tag mapping. Register presence does not establish enabled/updating/logged state.
- Overview's six-state indicator references main:dryer_g_m77_01_out_status.
- Center Receiving Start targets main:recvSeqStart with value 1.
- A Center Receiving ratio reads main:dryer_g_centRecBin21Ratio but writes main:dryer_g_centRecBin21RatioSel, writeValue=value. Limits checkbox was false despite populated 0/100.
- Sample dryer status address: tag sg_dryer.g.m77_01.out_status; enabled On Change/one-second polling, logging disabled in that earlier inspected definition.

These are dated prior observations, not a new register-table audit on October 21. The prior counts of 20,055 register definitions and 1,538 alarm definitions are historical, not freshly verified totals.

## Future work boundaries

Use this guide and the earlier full catalog instead of repeating the general survey. Verify current Title/slug and the particular subtree before editing. Preserve roots, location anchors, read/write distinctions, state mappings, chart series/scales/navigator and time conversions.

No PLC commands, setpoint writes, motor tests, alarm-latching changes or device actions were performed. History retention, alarm notification/latching and physical interlocks remain outside this survey. Old/test page names do not establish which content is current or safe to modify.
