An automation system is used to automate the processes using electrical or electronic equipment like oil refineries, industrial equipment’s automatically simply by embedding compatible hardware and software of application-specific function. It is also called a process automation system (PAS).
Some of the components used by PAS are sensors, networks, controllers, operating systems, which are an open standard distributed control system (DCS) that is based on a control system operated with a computer using plants or processes.
DCS are applicable in power plants like a nuclear plant, water treatment, processes like metallurgical, etc. In some conditions PAS is considered as SCADA – supervisory control and data acquisition control system, is an architecture that comprises of networks data, peripheral devices like PLC – programable logic controller, PID – proportional integral derivative controller.
SCADA is applicable in control systems like manufacturing, generation of a power system, ships, heat controllers, etc. the main disadvantage of SCADA is that it has network vulnerabilities.
