Industrial control system

from Wikipedia, the free encyclopedia

The industrial control system , a translation of the term Industrial Control System (ICS), is a general term that encompasses several types of control systems and associated instrumentation for industrial process control .

Such systems can range from a few modular panel controls to large, interconnected and interactive distributed control systems with many thousands of field connections. All systems receive data from remote sensors that measure process variables (PVs) , compare them with the desired setpoints (SPs) and derive command functions with which a process is controlled via the actuators (FCEs), e.g. control valves .

The larger systems are usually implemented using Supervisory Control and Data Acquisition (SCADA) systems or distributed control systems (DCS) and programmable logic controllers (PLC) , although SCADA and PLC systems are scalable down to small systems with a few control loops. Such systems are widely used in industries such as chemical processing, pulp and paper manufacture, power generation, oil and gas processing, and telecommunications. These systems are often classified as critical infrastructures (KRITIS) .
