Control System and Operator Interface
The operator interface does not normally replace the main automatic controller. Instead, it provides a way for authorized personnel to interact with the controller and observe system information.
Depending on the integrated system, operator functions may include:
- Monitoring operating conditions
- Viewing machine status
- Viewing alarms
- Entering operating commands
- Adjusting permitted parameters
- Observing system diagnostics
- Interacting with maintenance functions
The exact functions available depend on the associated control-system configuration.
Role in Industrial Control Systems
The operator interface provides an important link between human operators and automated control logic.
A typical control system may contain:
Sensors → Controller → Actuator → Machine
The operator interface adds:
Operator ↔ Controller
This arrangement allows the controller to continue performing automatic regulation while operators monitor operation and provide authorized commands.
For power-generation and rotating-machinery systems, this separation is particularly useful because the controller can handle real-time control while the operator interface provides a practical way to supervise the system.
