ASETPROJECT OBJECTIVE

To design a system using PLC with the specifications given: There are

four LEDs red, green, yellow and blue. Two push-button switches are

there for START, STOP and for LED selection there is SELECT switch.

The START button is pressed after that:

• Condition 1: If SELECT switch is pressed once then red LED glows.

• Condition 2: If SELECT switch is pressed twice then green LED

glows.

• Condition 3: If SELECT switch is pressed thrice then yellow LED

glows.

• Condition 4: If SELECT switch is pressed four times then blue LED

glows.

ASETRESULT AND FUTURE SCOPE

RESULT

The conditions mentioned in the objective are satisfied.

FUTURE SCOPE

• The project based on glowing different LEDs can be extended

in industry environment for doing different automated tasks by

usage of same set of hardware, just by changing the program

or logic stored in the PLC.

• If the PLC is connected with SCADA using ”Device

Connectivity” feature, various other features like Recipe

Management, Alarms etc. can be used to make the system

more reliable for the industrial environment.

OBJECTIVE AND SOFTWARE

REQUIREDPROJECT OBJECTIVE

To design ”Sewage Water Treatment System” in Wonderware Intouch

SCADA.

SOFTWARE REQUIRED

Wonderware Intouch version 9.0

WORKING OF PROJECT

When the START switch is turned on, water from the storage tank flows to

the sedimentation tank after passing through the screening filter. As soon

as the sedimentation tank is filled the rotator inside the tank is turned on so

as to deposit the sediments at the bottom of the tank.

Clean water from the sedimentation tank is transferred to the chlorine tank

where the water is chlorinated to kill the germs and make it fit for

drinking. Next, the water is oxygenated by passing oxygen gas into it in

the chlorine tank. The water from the chlorine tank is filtered and stored in

another tank for usage.15

ASETWINDOW SCRIPT USED

22

There are two parts in the script:

(1) On Show: how the things

should appear as soon as the

window viewer is started.

(2) While showing: how things

will appear once the task starts to

run on window viewer.

• Value of A is incremented when

A<105, the START switch is

kept on and the STOP is off.

The increment is done in 1 sec

period.

• As soon as A=105, the value of

A is reset to 0 and the process

repeats itself in an infinite loop

until the STOP switch is

pressed on.

ASETRESULT AND FUTURE SCOPE

23

RESULTS

The design of ”Sewage Water Treatment System” is

successfully implemented in Intouch SCADA

FUTURE SCOPE

This project can be implemented practically when SCADA is

connected with PLC. More enhanced features can be added up

to it. For e.g. R. O. purification system can be added.

2. The project based on sewage can be extended to water

purification systems, oil refinery systems in industries.

3. The project can also be extended to packaged drinking

water industries where water is first purified, then filled into

bottles, capped, labelled and then sold in bottles.
