DCS is Distributed Control System with very speed scan
time,also with expanded I/O's,able to control very
complicated large control systems.Field instruments with
Field bus and Profibus can be easily complitable eith DCS
when compared with PLC.

Answer / balaji

DCS is nothing but Distributed Control system.It is used to
control the process of distributed instruments.

Answer / amrit goyal

dcs is distributed control system to control the process of any industries. its a controller and distributed the control signal throughout the plant.

Answer / kalyankrishna

A distributed control system (DCS) is a control system for a process or plant, wherein control elements are distributed throughout the system.
A DCS typically uses custom designed processors as controllers and uses both proprietary interconnections and standard communications protocol for communication. Input and output modules form component parts of the DCS. The processor receives information from input modules and sends information to output modules. The input modules receive information from input instruments in the process (or field) and the output modules transmit instructions to the output instruments in the field. The inputs and outputs can be either analog signal which are continuously changing or discrete signals which are 2 state either on or off . Computer buses or electrical buses connect the processor and modules through multiplexer or demultiplexers. Buses also connect the distributed controllers with the central controller and finally to the Human–machine interface (HMI) or control consoles.
