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.
Bin G Hi-Hi enable/disable investigation — October 21, 2026
User requested an Atom HMI enable/disable control for Sweet Grass Bin G Hi-Hi. Inspected production https://www.atomhmi.com/site_sweetgrass/ after reading repository instructions and cloud knowledge/site guide. No site changes or operational writes were made; target alarm path needs clarification.
Verified in Main PC (main):
- HMI alarm ALM-436 has description ALM-436, message "Bin G Full", calculation
|{register:main:Alm436}|, enabled true, latching false, Warning importance, one-second update, zero on/off delays, notification groups Atom Notifications and Default Notifications. - Source register Alm436 is enabled, observed 0, Main PLC slave, Modbus slave 1, Coil 4427, Bit format, bit 0, Swapped checked; On Change/two-second update, logging disabled.
- Separate Codesys register clean_g_binG_lvl_limits_hihi_alm_in_en has description Bin G level and address
{ "tag": "sg_cleaning.g.binG_lvl.limits.hihi.alm.in_en" }. Enabled is unchecked; configured On Change/one-second update and logging disabled. No current value was available. This is a candidate alarm-enable input, not a verified control for ALM-436. - Separate clean_g_binG_lvl_limits_hihi_in_en, ...hihi_in_sp, ...hihi_out and ...hihi_alm_out definitions also exist with Enabled No. Do not conflate threshold enable with alarm enable or infer PLC write ownership from names.
- clean_g_binG_lvl_out_eu is enabled and observed about 84.45–84.56; this readback does not establish the alarm path.
- Main PC tables currently report 20,055 registers and 1,538 alarms. Searching Bin alarm messages found ALM-436 but no Bin G Hi-Hi message.
- Navigation Bins opens page_bin_2 (editor Title Bin 2, slug bin_2), which displays Bin G among the bin gauges. The separately configured Bins page (slug bins) displays H/J/bagging/K/L/M/N and is not the navigation target.
Asked whether the intended control is the Codesys level Hi-Hi alarm or the existing Main PLC Bin G Full alarm. Next: resolve the intended path and verified writable setting, add a supported native enable/disable control on the relevant operator page, preserve existing state, save/reload and verify configuration. Do not write Alm436 or an alarm output to simulate enable. No polling, thresholds, alarm definitions, notifications, latching, pages, or equipment commands changed during this investigation.
Alarm history lookup — October 21, 2026
User requested checking whether any Bin G alarm previously occurred. Opened the alarm icon → Alarm History at https://www.atomhmi.com/site_sweetgrass/alarm_history. Requested Last 30 Days (September 22–October 21, 2026), then freshly reloaded and requested October 21, and finally Yesterday (October 20). Every attempt remained on Loading... without a history table, records, or an explicit empty-result message. No browser warning/error logs were captured. Occurrence, timestamps and retention therefore remain unverified; this is not evidence of no prior Bin G alarms. No acknowledgement, reset, alarm edits, register writes or page saves performed. Next: retry when history retrieval works, search Bin G / ALM-436 / Codesys Bin G Hi-Hi identifiers, and record the returned range and timestamps.
