SCADA is the Software tool in which you can able to
view/Monitor/Control your Process Variable data and
Graphical representation of your plant etc...
It's an operator front end display
Example of few SCADA S/W is Wonderware, IFix, RS View,
WinCC etc

DCS is the System in which controller are distributed
geographically and integrated all the control hardwares
which is connected from the various field devices
DCS having its own network, Controller and HMI etc…
Honeywell, Yokogawa, Invensys, ABB, Emerson are the leading
DCS Vendors

Answer / rafiq

dcs is nothing but distributed control system. i.e we are
distributing the control system
scada is nothing but supervisory control and data
acquisition. i.e it gathers the data from the process and
decides after that sends an response to the controller

Answer / awande mandlazi

DCS: DISTRIBUTED CONTROL SYSTEMS: THIS SYSTEM DOES WHAT A
PLC WOULD DO, BUT THE DIFFERENCE IS THAT A DCS IS USED IN
MUCH LARGER AND COMPLEX APPLICATION E.G: POWER GENERATION,
SOME COLD ROLLING MILLS etc.

SCADA: AS ALREADY EXPLAINED, IT NOTHING BUT A SOFTWARE USED
TO GATHER DATA FROM THE FIELDS INSTRUMENTS WITH THE HELP OF
YOUR DCS OR PLC DEPENDING ON THE APPLICATION VIA THE SERVER
AND MAKING IT AVAILABLE IN AN ANIMATED FORM. THIS IS
USUALLY FOUND IN YOUR CONTROL ROOMS AND DEVELOPMENT ROOM

Answer / srinivasan narayanan

SCADA abbreviated as Supervisory Control and Data Aquision. Simply it will collect the date from the hardware controller (DCS, PLC) and shows the process variables like Pressure, Temperature, Flow, Level etc.This software product used to monitor, control(by using back end Hardware controller like DCS, PLC etc) your process data

Whereas DCS abbreviated as Distributed Control System. DCS having it's own network, Hardware controller and Software Package. The system having different Hardware controller connected in the network (own by individual vendor like Honeywell, Yokogawa, Foxboro, ABB, Emerson etc) and shows the process variable through SCADA S/W. It's integration of Hardware (different types) and Software using the common network.

Both system plays major role in Industrial Automation sector

Answer / rahul mishra

distrbuted control sytem is system in which more then one
proceser on sigle platform.
scada is superisery control which hold all the dats of many
processe.

Answer / ahmed allam

DCS (processor + logic + graphic) = PLC (processor+logic) + SCADA (grahpic)

the different between DCS and PLC+SCADA(HMI) No. of I/O only

Answer / ashutosh tiwari

plc is the hardware controlling system and scada is the software controlling syetem this is the major difference between these two

I have one DP transmitter of range 0-500mmWC i have to calculate its range in M3/hr for flow measurement so whats the formula.

4 Answers   ABB, TICB,

During valve sizing from all calculation you got flow coefficient CV 12,than what it means? like for selecting pressure transmitter if your MAWP is 12 bar than you select a capsule of max. 20 bar which cover your mawp 12 in same way for selecting control valve If CV is 12 than how we use it in selecting valve??????

4 Answers   Schneider,

A DP transmitter is used to measure the level of an open tank. The drain line of the tank is connected to a control valve, and is configured as, if the level of the tank is 90% the valve should get open 10%. And if the tank level is 10%, the valve should get open 90%. Draw wiring diagram and explain how to configure DP transmitter and control valve using HART communicator. If the span error at output is 1%, what will be the %opening of the control valve at 60% level of the tank?
