2. Introduction
DCS(Distributed Control System)- DCS is a
dynamic control system ,in which controllers
are distributed throughout the entire system
is connected by a network

3. DCS Display
The output of process are is shown at
different of display
Types of display
Trend display
Group display
Schematic display
Detail display
Standard or user defined display
Alarm Display
Loop display

4. Trend Display
Used for analysis the condition of plant in
detail and measure unwanted signals

5. Group display
Demonstrate the operating parameters of
control loops such like feed water, drum level,
steam flow , pressure

6. Schematic display
Schematic display shows the pictorial view of
plant.

7. Detail display
Provides appearance of all parameters related
to the particular point of process

8. Standard display
Its like a block diagram of process plant who is
made by technician

9. Alarm Display
It show the emergency situation of process
plant

10. Loop control
Loop control display show the closed loop
display of process plant

11. Continuous Process Display
It is used to show the what process is runing
at the current stage

12. Graphic Display
Its is a pictorial view on screen so that the
operator realize the process by bar graphs

13. Batch Display
Show the status of process modules related to
a particular batch

14. Overview Display
The operator looking at an overview display ,
can see at a glance the condition of all the in a
number of operating areas

16. Advantage and disadvantage
Advantage Disadvantage
Quality control Demand skillful operators
Reduced installation and wiring costs Operators have alert and
careful while processing
Good operating efficiencies It is closed loop control
when one component is
failure it can affect on
whole system
Flexibility- each part can be alter by
software
Complex and expensive
