DCS: A Distributed Control System (DCS) is a digital automated industrial control system (ICS) that uses geographically distributed control loops throughout a factory, machine or control area.
SCADA: Supervisory Control and Data Acquisition (SCADA) is a control system architecture comprising computers, networked data communications and graphical user interfaces for high-level supervision of machines and processes.
PLC: A Programmable Logic Controller (PLC) is an industrial computer control system that continuously monitors the state of input devices and makes decisions based upon a custom program to control the state of output devices.
