1.5 Control System Architecture
Industrial Automation 3 1.5 Control System Architecture
Principle
The control system is a communication system consisting of controllers and links.
The structure of the control system should reflects that of the plant
Ideally, each unit of the plant should have its own controller,
interacting with the controllers of the other, related units,
mirroring their physical interaction.
Example: Airbus: a wing is delivered with its own computers.
