Major Types of Industrial Control Systems
Industrial control system or ICS comprise of different types of control systems that are currently in operation in various industries. These control systems include PLC, SCADA and DCS and various others:
PLC
They are based on the Boolean logic operations whereas some models use
timers and some have continuous control. These devices are computer
based and are used to control various process and equipments within a
facility. PLCs control the components in the DCS and SCADA systems but
they are primary components in smaller control configurations.
DCS
Distributed Control Systems consists of decentralized elements and all
the processes are controlled by these elements. Human interaction is
minimized so the labor costs and injuries can be reduced.
Embedded Control
In this control system, small components are attached to the industrial
computer system with the help of a network and control is exercised.
SCADA
Supervisory Control And Data Acquisition refers to a centralized system
and this system is composed of various subsystems like Remote Telemetry
Units, Human Machine Interface, Programmable Logic Controller or PLC
and Communications.
