SCADA, HMI AND PLC
INFORMATION TECHNOLOGIES
Supervisory Control and Data Acquisition (SCADA) is a control system architecture that uses computers, networked data communications and graphical user interfaces for high-level process supervisory management. Also uses other peripheral devices such as programmable logic controller (PLC) and discrete PID controllers to interface with the process plant or machinery.
The main point is in:
- people safety and comfort
- real-time working systems
- global monitoring and control
- local independence in case of failure
- user friendly interface with level access
- priority of alarm messages and early problem define
- control from a distance
