Section 4: OT Component Roles in an Industrial System
While each OT component has a specific technical function, their true value emerges through integration — when they operate as a coordinated ecosystem.
In a typical industrial setting, these devices communicate continuously to keep the production process efficient, stable, and safe.
- PLCs control operations like conveyor belts.
- HMIs display machine status.
- RTUs connect remote sites to the control center.
- SCADA provides centralized visibility and control
