Industrial Automation Overview — PLC SCADA Robotics

Industrial automation transforms manufacturing by replacing manual processes with computer-controlled systems. From simple conveyors to complex robotic cells, automation improves consistency and throughput.

Levels of Automation

• Fixed: Dedicated high-volume equipment (transfer lines)
• Programmable: Reprogrammable for batches (CNC, robots)
• Flexible: Quick changeover, high-mix volumes
• Integrated/Smart: IoT, cloud data, AI-driven (Industry 4.0)

Core Technologies

• PLC: ruggedized industrial controllers
• SCADA: central plant monitoring
• DCS: decentralized continuous process control
• Industrial robots: 6-axis, SCARA, cobots
• Sensors: temperature, pressure, vision
• HMI: touchscreen operator interface

Benefits

• Productivity: 3-5x vs. manual
• Quality: defect rate from ~5% to < 0.1%
• Labor: one cell replaces 3-6 operators/shift
• Safety: machines handle dangerous tasks
• Data: every cycle → process insights

ROI in China

Typical payback 12-24 months. Factors: labor savings (3-5 operators × 2-3 shifts), quality improvement, 30-200% throughput increase. Equipment: ¥100K-3M per cell depending on complexity.
