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. The goal of a DCS is to control industrial processes to increase their safety, cost-effectiveness and reliability.
A control system is a set of mechanical or electronic devices that regulate other devices or systems through the use of control loops. Control loops are systems composed of all the hardware and software control functions needed for measurements and adjustments in an individual process. Control systems are a central part of industrial and process automation systems.
