Usually , it is for process control purposes
3 elements involved :
Types of computer-oriented control system
- DCS (Distributed control system)
- PLC (Programmable Logic Controller)
- PC (Personal Computer)
- Embedded controller
Computer
Dedicated-application system
- Where the system is dedicated to perform a single task or a single group of tasks
- Examples : Microwave, ECU, Calculator
- A microcomputer/controller receives input information
- Executes a sequence of instruction to process the information
- Provides output
Example of Dedicated-application system
Engine status display system
- The input information (engine parameter: temperature, oil pressure,etc) is converted to an electrical quantity by some type of transducer.
- The electrical quantities are then converted to a digital form to be inputted to the microcomputer system (µC)
- The µC processes the input data
- Then outputs the information to the display panel
