dcs is a distributed control systems

Answer / indranil mukherjee

Dcs is a automated contollable system which functionaly and
graphically distributed.

Answer / kamran

dcs is a control system in which the controller elements are
not central in location but are distributed throughout the
system with each component sub-system under the control of
one or more controllers

Answer / ibrahim s

DCS(distributed control system):

*Group of PLC connected in a single loop, additionaly it
cabable handle more input and output.

*A server and/or applications processor may be included
in the system for extra computational, data collection, and
reporting capability.

Answer / k k rameshkumar

DCS means Distributed Control System. In this the
controllers/control are physically/geographically
distributed. For overall control, all the controllers are
exchanging signals in unison with the supervisory controller
(Normally the Main CPU) to control the whole system.
Generally it is a PC based control system

Answer / r.vijayan

DCS is Nothing but Distributed control System which will be
mainly used in process industries to control a entire plant
operation. The entire plant will be diveded into sub areas
and each will be controlled by separate PLC and all these
PLCs are integrated into one supervisory system where
operator contol and monitoring action takes place.
We can as simply that DCS = SCADA + PLCs.

Answer / kamal rawat

A distributed control system (DCS) refers to a control
system usually of a manufacturing system, process or any
kind of dynamic system, in which the controller elements
are not central in location (like the brain) but are
distributed throughout the system with each component sub-
system controlled by one or more controllers. The entire
system of controllers are connected by networks for
communication and monitoring.


DCS is a very broad term used in a variety of industries,
to monitor and control distributed equipment.

Answer / rabindra

dcs means distrubuted control system. it handels large
amount of I/O.

Answer / hafiz rana m.aqib

Abbreviation of DCS is "Distrubted Control System" which is
used for Monitoring and Controlling

Answer / lee naidoo

it is system that controls instruments in the plant,
however there are several controleers that are distributed
tthroughout the plant, hence Distributed control systems
(DCS).example one controller controlls the filling of
bottles with milk, another controller controls how the
bottles get packed in a crate, etc.however all these
controllers are networked and share information.
