The Problem
What the plant was facing
Data was trapped inside individual PLCs and HMIs on the shop floor. Management had no consolidated view of OEE, energy consumption, or downtime causes across lines — making improvement decisions reactive and slow.
Our Solution
What we engineered
- Deployed edge gateways polling Siemens, Delta and Mitsubishi PLCs over Modbus TCP and S7
- Time-series store in SQL with roll-ups for shift, day and month
- Web-based dashboard with live KPIs, OEE, and downtime pareto
- Alarm push to WhatsApp/email for critical events
- Role-based access for operators, supervisors and management
