Distributed control system Wikipedia

A distributed control system (DCS) is a computerised control system for a process or plant usually with many control loops, in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control.This is in contrast to systems that use centralized controllers; either discrete controllers located at a central control room or within a central

What is Distributed Control System (DCS)? ELECTRICAL

A distributed control system (DCS) is a specially designed automated control system that consists of geographically distributed control elements over the plant or control area. It differs from the centralized control system wherein a single controller at central location handles the control function, but in DCS each process element or machine

What is a Distributed Control System? Control Station

Apr 24, 2018 In a recent blog post we paid tribute to Dick Morley and his pivotal contribution to the process automation industry: the Programmable Logic Controller (PLC). Since the PLC and Distributed Control System (DCS) are both instrumental in controlling complex production processes, people occasionally use the two terms interchangeably. While the two are related, their applications are

Concept of Redundancy in Control Systems Instrumentation

The Mean time between failures of any system dependent upon certain critical components may be extended by duplicating those components in parallel fashion, such that the failure of only one does not compromise the system as a whole. This is called redundancy.. A common example of component redundancy in instrumentation and control systems is the redundancy offered by distributed control
