Project Using PLC: A Pharmaceutical
plant
OBJECTIVE : To design a pharmaceutical plant using Programmable
Logic Controller for manufacturing of a medicine in which two different
liquid should mix in equal quantity and then this mixture should be heat for
20 seconds on a constant temperature of 100 C.
Hardware and Software Used:
1. PLC: Allen Bradley Micro Logix 1000 with 10 Input / Output.
2. Programming Software: Rockwell software RS Logix 500 English
3. Communication Software: RS Linx.
4. Programming Language: Ladder Logic.
5. Communication Protocol: RS 232
6. Other Hardware: Push Buttons, Light Emitting Diode.

FLOWCHART
Working of Project:
The process involves mixing of two different
liquids in equal quantities.
The process is start by pressing the START
button.
When the START button is pressed, the two
liquids starts mixing, this is indicated by
glowing of two output LED.
 Next, after a time lapse of 20, seconds the
third LED glows indicating that the mixture is
heated for 20 seconds, at 100 C.
STOP button is pressed to stop the process.

Rung 0000 :The START switch is represented by XIC I:0/0 and the STOP switch
is represented by XIO I:0/1. I represent input. The output is a binary bit B3:0/0.When
START button is pressed the input I:0/0 is HIGH and input I:0/1 is already HIGH
because its XIO. This energizes the output B3:0/0.
Rung 0001 : B3:0/0 acts as input to the TON timer T4:0/0 with preset value 30
and accumulator value 0.
Rung 0002 : B3:0/0 acts as the input to two parallel outputs O:0/0 and
O:0/1.These outputs represent the output LED. Two liquids are being mixed in a
container
Rung 0003 : (a)The DN bit of timer T4:0 i.e. T4:0/DN acts as input to the timer
T4:1.
(b) This T4:1 indicates the time for which the mixture of the two liquids
is to be heated at 100 C.

Rung 0003:
(a) As stated above when accumulator value becomes equal to the preset
value the DN bit of the timer T4:0 goes HIGH. When this happens the
accumulator value of TON timer T4:1 starts to increase till it
reaches the value equal to that of preset (=20).
Rung 0004:
(a) The DN bit of T4:1 i.e. T4:1/DN is connected to the output O:0/2.
The O:0/2 represents the third output LED.

As soon as T4:1/DN goes HIGH, the output O:0/2 is energized and the third LED
starts to glow.
(b) The glowing of third LED indicated that the heating of the mixture is
completed.
(c) After this the STOP button (I:0/1) is pressed i.e. XIO I:0/1 goes LOW and the
whole process is reset.
Results
The two liquids were mixed (indicated by glowing of first two LED) and the mixture
was heated for 20 seconds (indicated by glowing of the third LED).
Future Scope
1. When connected with SCADA using the Device Connectivity feature of SCADA,
the project can implemented with Recipe Management feature of SCADA. This way
we can change the ingredients of the mixture.
2. This project can be extended to filling of the mixture into different bottles then
labeling and packing them i.e. making a fully automated medicinal syrup
manufacturing plant.

Project Using SCADA : Bottle
Filling & Capping Station
Project Objective : To design a ”Bottle filling and Capping Station”
using Wonder ware Intouch SCADA.
Software Used : Wonderware Intouch version 9.0.
Working of Project:
The project is made in Window Maker and executed in Window Viewer. In
window viewer, the project would run as:
When the switch is turned on, a bottle will be filled to full by three different tanks
filled with different liquids as indicated by their color.
Liquid poured to the bottle when its presence under the tank is sensed.
Then a clamper brings down the cap to the mouth of bottle, places it there and then
returns back to its original position.
The bottle is capped is then moved to the storage.

1. In the Intouch Application Manager, select file New Create new Application.
This creates a new Intouch application.
2. Double click on this application, it opens Intouch Window maker.
3. In Window maker we select File New Window. A dialog box appears asking for
name, window type, window color and other properties.
4. We name the window as ”bottle fill transfer”, window type as replace , frame
style as single and click on OK. A window appears as per defined by us.
5. Wizard icon Wizard Selection window graphical objects.
6. Wizard Selection window symbol factory option double click
8. In the symbol factory window there are various categories of the graphical
objects like Tanks, Containers etc. We select the different objects as per
our requirement.

For all the objects taken from the symbol factory, we perform Break Cell operation
so that we are able to change their properties as per our requirement. Following is the
figure showing the list of the properties available for each object from Symbol
Factory:

We see that there are different bottles under the tanks whereas in the run time we
require only one of them. This is done keeping in mind the visibility of each bottle.

Since there is no manual work i.e. no
slider is being used, window script
has to be used for incrementing the
value of the counter, whose tag name
is used as the expression for all other
objects.
There are two parts in the script:
(a) On Show: how the things should
appear as soon as the window
viewer is started.
(b) While showing: how things will
appear once the task starts to run
on window viewer.

Results
The design of ”Bottle Filling and Capping Station” 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. Some features are:
1. Automatic Labeling of Bottles.
2. Defected Bottles such as bottles without cap or less in weight should be
automatically removed.
3. Automatic pick up of bottle after filling it up.
