The Yamastro Platform
Process intelligence software for mid-size Japanese factories. PLC-native data ingestion, real-time OEE（総合設備効率）, andon（アンドン）alerting, lot traceability — in a single integrated layer.
Five modules. One integrated layer.
Data Ingestion
Connect to your existing factory equipment without a multi-month integration project. The Yamastro edge agent supports all major industrial protocols and runs on-premise, reducing network exposure.
- OPC-UA 1.04 — for modern PLC and SCADA systems
- Modbus TCP/RTU — for legacy equipment and sensors
- MQTT — for IoT gateways and edge devices
- Direct PLC polling via Mitsubishi, FANUC, and Siemens native drivers
- Manual input station integration for operator-entered data
- Flat-file import from SCADA historians (CSV, OPC-HDA)
OEE Engine
Calculates OEE（総合設備効率）in real time — per line, per shift, per SKU. No more weekend consolidation. The engine normalizes timestamps across all data sources and applies your planned time and speed definitions.
- Availability (稼働率) — unplanned downtime detection and classification
- Performance (性能稼働率) — cycle time vs. ideal speed
- Quality (品質稼働率) — first-pass yield tracking
- Six Big Losses breakdown dashboard
- Historical OEE trending and shift comparison
- Per-SKU OEE for high-mix lines
Alert Manager
Digital andon（アンドン）that carries the discipline of the original concept. Threshold-based alerts with severity tiers and escalation chains — so operators respond to signal, not noise.
- Configurable OEE threshold alerts (line, cell, machine level)
- Severity tiers: Info / Warning / Critical
- Escalation chains — from operator to supervisor to manager
- Mobile push notifications for shift supervisors
- Alert fatigue controls — minimum interval, grouping logic
- Alert history and response-time audit log
Traceability Ledger
Full lot genealogy from raw material receipt to finished goods shipment. A single query answers customer audit requests, supplier quality holds, and regulatory inspections.
- Lot genealogy tree — multi-level parent/child relationships
- Raw material consumption linkage per production order
- Process parameter capture at each operation
- Non-conformance event association
- Export to PDF and structured data for regulatory submissions
- Recall scope calculation — identify all affected downstream lots in seconds
API & Integrations
Yamastro integrates with your existing ERP and quality systems — sending enriched production data upstream without requiring a middleware layer.
- REST API for bi-directional data exchange
- SAP, Oracle, and Infor connector templates
- Flat-file export for ERP systems without API capability
- Webhook support for real-time event push to downstream systems
- Role-based API access with token authentication
- Audit log of all API calls
