Supervisory control and data acquisition is a control system architecture comprising computers, networked data communications and graphical user interfaces for high-level process supervisory management, while also comprising other peripheral devices like Programmable Logic Controllers (PLC) and discrete Proportional-Integral-Derivative (PID) controllers to interface with process plant or machinery. The use of SCADA has been considered also for management and operations of project-driven-process in construction.
SCADA is a system that aims to monitor and control field devices at your remote sites. SCADA systems are critical as it helps maintain efficiency by collecting and processing real-time data. SCADA is a centralized system that monitors and controls the entire area.
