Question { ABB, 26662 }

WHAT ARE MAIN DIFFERENCE BETWEEN DCS AND SCADA?

Answer

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
