7 critical tags streaming every 1.5 seconds. Anomalies graded in real time. Auto-brief regenerated continuously. All data simulated client-side — no network, no real mine. The architecture below is what runs on real sites today.

Pit 4 · Tier-2 WA Iron Ore · 06 Aug 2026 · 06:00 AWST. All 7 critical tags within nominal band over the last 30 minutes. No action items.
// PRODUCTION BRIEF SHIPS DAILY AT 06:00 LOCAL · DEMO BRIEF STAYS PUT UNTIL YOU CLICK REFRESH OR INJECT AN ANOMALY
DARA's OPC UA / Modbus / PI Web API connector reads tags every 30-60 seconds from inside your DMZ. Read-only client, never writes. No PLC touch.
TLS 1.3 outbound to AU-sovereign DARA cloud. Tenant-isolated workspace. AES-256 at rest. No multi-tenant data co-mingling.
DARA Engine compares each tag against historical baseline, cross-site benchmarks, and tag-pair correlations (shovel cycle ↔ truck payload ↔ belt rate). Anomalies graded.
Operations superintendent's inbox gets a one-page reconciled brief at 06:00 local each morning. Variance, root-cause hypothesis, action items. Audit-defensible.
DARA does not run a PLC. It does not actuate equipment. It does not write to your historian.
DARA does not replace your control room. It supplements the morning superintendent meeting.
DARA cannot ingest tags it doesn't have read access to. Scope is whatever your IT team exposes.
Tier-2 site (≤200 critical tags · existing historian) onboards in 3-4 weeks. Greenfield Modbus-only sites in 6-8 weeks.
DARA absorbs the connector build, cloud, and inference costs. You provide read-only access to one historian or FMS and a 30-minute superintendent intro. First reconciled brief in 4 weeks.
