WHAT ARE MAIN DIFFERENCE BETWEEN DCS AND SCADA?
Answer Posted / 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

We Have Two Field bus Pressure Transmitters of Different Sensor Range (I.E One is of Lower range and Another is of Higher Range).Is same Process Line. My Question is Can i provide Saturation Limit to my field Bus Transmitter as We can provide Saturation current limit to HART Instruments. As During Low Pressure Both Working OK ,But During High Pressure, transmitter with Lower sensor range Goes to Fault mode as Beyond its Sensor Limit it can Measure, So may I provide Saturation point Some where to Suppress This Fault during High Pressure.
