Detailed analysis of SCADA (Supervisory Control and Data Acquisition) architecture, real-time OEE tracking, alarm management, and cost-benefit calculation.
In modern manufacturing, data visibility is the cornerstone of operational excellence. A SCADA (Supervisory Control and Data Acquisition) system bridges the shop floor machines with enterprise MES/ERP software.
1. What is SCADA and How Does It Work?
SCADA is a multi-tier industrial software system that collects real-time telemetry from PLCs, sensors, and RTUs, visualizing operations through intuitive HMI graphics and archiving parameters in SQL historians.

- Dynamic Synoptic Visualization: Real-time animated schematics showing line status, cycle states, and machine speeds.
- Standardized Alarm Management (ISA 18.2): Tiered classification (Critical, Warning, Info) to prevent operator alarm flooding.
- High-Speed Historical Trending: Millisecond-level logging of pressure, temperature, and torque for root-cause quality audits.
- Automated Recipe Management: Single-click parameter dispatch across multi-product flexible packaging lines.
- Real-Time OEE & Downtime Tracking: Automated calculation of Availability x Performance x Quality.
3. Realized ROI & Cost Savings
| Metric | Before SCADA Implementation | After SCADA Implementation | Net Gain |
|---|---|---|---|
| Unplanned Downtime | 14.2% | 4.8% | -66% Downtime |
| Overall Equipment Effectiveness (OEE) | 62.5% | 84.1% | +34% Capacity |

Sıkça Sorulan Sorular
SCADA ile HMI arasındaki fark nedir?
HMI genellikle tek bir makinenin başında operatör paneli olarak kullanılır; SCADA ise tüm fabrikayı, üretim hatlarını ve veri tabanlarını merkezi olarak izleyip yönetir.
