difference between DCS @ SCADA system? and how can use in field ..

Answer / deepan.p

DCS-ITS A CONTROLLER IT HAS PROCESSORS AND MODULE LIKE ANALOG
I/O,DIGITAL I/O,RTD,T/C,VALVE POSITION MODULE ETC
WE CAN CONTROL AND MONITER THE PROCESS.
SCADA- IT ONLY A USED TO MONITOR THE PROCESS &WE CAN CREATE
THE GRAPHICS OF PROCESS SOMETHING.ITS NOT USED ALONE.IT JUST
CONNECTED WITH PLC ETC.
DCS IT SELF CONTAINS SCADA SOFTWARE

Answer / jigneshsolanki

THERE IS MAINLY TWO DIFFERENT BEETWIN dcs & scada SYSTEM
1) DCS system it self whole control system & SCADA system required plc for controlling.

2)dcs SYSTEM scan time is nearly 1sec & SCADA with PLC system scan time is in millisecond(depends on program).

3)DCS having Large I/O capacity with respect to SCADA with PLC system.

Answer / shailesh kumar chauhan

dcs is a system through which u can connect more than one system to control like HMI, PLC, PDI . scada is a supervisory software through which you can make same to same copy (graphics) of your process plant

Answer / cubes

DCS IS DONE TO AUTOMATE A PLANT. IT IS DONE WITH THE HELP OF
PLC'S AND SCADA.SCADA IS THE SYSTEM THAT PROVIDE THE
MONITORING AND CAN PERFORM ONLY PROCESS OUTPUT CONTROL.HENCE
IT IS A SUPERVISORY CONTROL.

DCS : Distributed Control System , to control and monitor process over plant or a defined limited Area , platforms

SCADA : Supervisory Controlled and Data Acquisition is a a pecific I/O's but distributed over a distant , like pipeline thru dessert ,...etc

Q1: Consider part of a control loop, which excludes the transmitter, consisting of a process, a controller and a control valve which may be represented by two dead times of 0.5 min each and three exponential lags of 0.8 min., 1.0 min. and 1.5 min. respectively. We wish to express this system as an overall first order plus dead time (FOPLD) model ie gain, time constant and process dead time. (We will see later that this is often done, to simplify controller tuning). For this exercise, gain is considered to be 1.0. (A) If the transmitter is a flow transmitter whose behaviour can be described by a dead time of 0.2 min. and an exponential lag of 0.5 min. in terms of the overall dead time and overall first order lag how can the system behaviour be approximated ? Overall dead time = Overall time constant = (B) If the transmitter is a temperature transmitter with a temperature sensor in a protecting well whose behaviour can be described by a dead time of 0.7 min. and an exponential lag of 15 min. how can the overall system behaviour be approximated now? Overall dead time = Overall time constant =

HELLO FRENDS ,, I M IN THE MIDST OF TROUBLE .. JUST LITTLE HELP ME... SUPPOSE ,, I HAVE A CLOSE VESSELE TANK ( HEXANE MEDIA ) ,, I M USING ROSEMOUNT 2051 DPT FOR LEVEL APPLICATION .. ITS CALIBRATE RANGE IS.. . 0 TO 950 MMH20 ..I DID CALIBRATED DPT WITHOUT REMOVING IMPULSE LINE OF HIGH AND LOW TAPPING.. & WITHOUT DISTURB 3 WAY MANIFOLD..!!! BUT ,,, DURING CALIBRATION I SELECT RANGE BY HART LRV IS 900 MMH20 & URV IS 1300 MMH20 ,, BUT ,TANK LEVEL SOMETIMES 100 % AT 1100 MMH20 , SOMETIMES 1300 MMH20 ..IN THIS CONDITION .. WHOLE LOOP FAILED ,, MAIN THING IS THAT ,, HOW TO CUSTOME RANGE SELECT ?? AND IF I USED RANGE OVER THE ORIGINAL CALIBRATE RANGE ,,,THEN WHAT ERROR WILL BE COME ??? HOW TO ZERO CALIBRATION OF DPT... HOW TO ZERO TRIM BY MANIFOLD ?? AND FOR TANK LEVEL PURPOSE ... WHICH UNIT I CAN USE ??? IS THERE ANY CALCULATION OR CALIBRATION .. IF YEH .. THEN PLZ JUST GIVE ME CALIBRATION STEPS FOR DPT.. THANKS YOURSSSSSSS
