INTRODUCTION TO SCADA
• SCADA (Supervisory Control and Data Acquisition) systems are
used to monitor and control a plant or equipment in industries
such as telecommunications, water and waste control, energy,
oil and gas refining, and Transportation (airport, traffic control,
rails)
• These systems encompass the transfer of data between a
SCADA central host computer and a number of Remote
Terminal Units (RTUs) and/or Programmable Logic Controllers
(PLCs), and the central host and the operator terminals
4

INTRODUCTION TO SCADA
• A SCADA system gathers information (such as where a leak on
a pipeline has occurred), transfers the information back to a
central site, then alerts the home station that a leak has
occurred, carrying out necessary analysis and control, such as
determining if the leak is critical, and displaying the
information in a logical and organized fashion
• These systems can be relatively simple, such as monitoring
environmental conditions of a small office building, or very
complex, such as a system that monitors all the activity in a
nuclear power plant or the activity of a municipal water
system or any other system.

LAYER PATTERN
• SCADA system being highly complex and distributed, it is
important to understand SCADA in Terms of Layers for
simplicity as shown in Figure above. The intent, forces,
advantages for the layer patterns are the same. However
here we apply this pattern on the real physical system.
• Layer 1: It is the field Units, considering the Generation,
Transmission and Distribution at one place, we have all the
process controls, I/Os, status, metering, measuring values,
etc. It also includes local control.
• Layer 2: The field values, I/O – analog, digital, measuring
and other commands, operations, are taken to RTUs, IEDs,
PLCs, BCUs, and other I/O cards to communicate to higher
end.
11

• Layer 3: This includes all the communication cables, protocol
architecture required for higher end communication
interfaced with all field signals. It is the backbone in the
modern control centers, which has immensely reduced
physical wiring, big marshalling and increased the reliability
and more improved quality signals. Today latest protocols like
IEC 61850, Modbus and other proprietary protocols are used.
• Layer 4: This includes the Control centre equipped with
dynamic changing states of the system displayed on HMI,
which is powerful to read values, prompt and diagnosis
system change and with a click on HMI, to carry out
operations.
12
LAYER PATTERN

• Layer 5: Connection with the outside world using Internet and
various new technology related to mobile / cell phone
operations.

APPLICATIONS OF SCADA
• Electric power generation, transmission and distribution: Electric
utilities detect current flow and line voltage, to monitor the
operation of circuit breakers, and to take sections of the power grid
online or offline.
• Buildings, facilities and environments: Facility managers use
SCADA to control HVAC, refrigeration units, lighting and entry
systems.
• Manufacturing: manage parts inventories for just-in-time
manufacturing, regulate industrial automation and robots, and
monitor process and quality control.
• Mass transit: regulate electricity to subways, trams and trolley
buses; to automate traffic signals for rail systems; to track and
locate trains and buses; and to control railroad crossing gates.
• Water and sewage: State and municipal water utilities use SCADA
to monitor and regulate water flow, reservoir levels, pipe pressure
and other factors.
• Traffic signals: regulates traffic lights, controls traffic flow and
detects out-of-order signals.

WONDERWARE INTOUCH

WINDOWMAKER PROGRAM
ELEMENTS
• WindowMaker is the development environment
for InTouch.
• The WindowMaker supports floating and docking
toolbars, right-mouse click menus throughout for
quick access to frequently used commands and a
customizable color palette that provides 16.7
million color support.
• WindowMaker's Application Explorer provides
you with a powerful, graphical method for
navigating and configuring your InTouch
applications.
25

WINDOWMAKER PROGRAM
ELEMENTS
• It provides you with easy access to WindowMaker's
most commonly used commands and functions such
as, all windows commands, all configuration
commands and all InTouch QuickScript editors.
• Additionally, the Application Explorer will display all
installed add-on programs such as SQL Access
Manager, SPC Pro and Recipe Manager and it provides
you with a customizable application launcher.
• You can configure the Application Explorer to launch
any other FactorySuite program or Windows program
to quickly switch between HMI configuration, I/O
Server configuration and control configuration.
26

CONTENTS OF WINDOWMAKER
• Simple Objects:
– Lines: A line object is made up of one or more line
segments depending on the type of line.
– Filled shapes: Filled shapes are two dimensional
objects made up of a closed interior area surrounded
by a line.
– Text: Text is an object made up of a string of
characters on a single line.
– Buttons: The 3-dimensional buttons can be created for
any desired size by using the Button tool on the
WindowMaker Draw Object Toolbar.
27

CONTENTS OF WINDOWMAKER
• Complex Objects
– Bitmap: The Bitmap tool is used to copy and paste bitmaps into
your application.
– Trends: There are two trend tools: one is for creating trends that
display real-time data and the second is for creating trends that
display historical data
– Symbols A symbol is a combination of simple objects (lines,
filled shapes, and text) which is treated as a single object.
– Cells: A cell is a collection of two or more objects, symbols, or
other cells that are joined together to form a single unit.
– Wizards: Wizards save you a considerable amount of time
during application development. They are easy to use and easy
to configure.
– ActiveX Controls: WindowMaker supports ActiveX controls
which, in their simplest form, are mini-applications that talk to
or run within your application.
28

TAGNAME DICTIONARY
• The Tagname Dictionary (runtime database) is
the heart of InTouch.
• At runtime, the database contains the current
value of all of the items in the database.
• In order to create the runtime database,
InTouch requires information about all of the
variables being created.
• Therefore each variable must be assigned a
tagname and type.
29

CREATING QUICKSCRIPTS IN
INTOUCH
• InTouch scripting is one of the most powerful
features of an InTouch application.
• The InTouch QuickScript capabilities allow you to
execute commands and logical operations based
on specified criteria being met.
• QuickFunctions are scripts that you create that
can be called from other scripts and animation
link expressions.
• By using scripts, a wide variety of customized and
automated system functions can be created.
30

WINDOW SCRIPTS
• Window Scripts are linked to a specific
window.
• There are three types of scripts that you can
apply to a window:
– On Show: Executes one time when the window is
initially shown.
– While Showing: Executes continuously at the
specified frequency while the window is showing.
– On Hide: Executes one time when the window is
hidden.
31

EXAMPLE- BOTTLE FILLING
Question:
Construct a conveyor carrying empty bottle.
When switch is in ON condition, the conveyor starts
to move. When it reaches the filler unit, the empty
bottle should be fully filled. When it reaches the
topper unit, the fully filled bottle must be capped or
topped. After that the bottle must be send to
packing unit. When 3 bottles arrives to the packing
unit, it must be packed together and send to the
storage unit or delivery unit.
32

Answer:
i. Open Wonderware InTouch software and create a new file.
Thus a new window appear known as Window maker.
ii. Drag the required components from the Symbol factory and
construct the bottle filling unit according to the question.
iii. Give separate tag names to each and every component. Note
that switches must be in Memory discrete and the moving
components must be in Memory real.
iv. After that write down the initial condition in the On Show
according to the syntax.
v. After writing the On Show, write down While Show as
required by the question.
vi. Assign the speed to 1ms or greater values.
vii. Validate it and check the errors.
viii. After clearing the errors, go to runtime. Thus a new window
known as Window Viewer appears and we can see the
animated result of the question.
33

On Show
s = 0;
b1 = 0;
b2 = 0;
b3 = 0;

f = f – 100;
IF b1 == 320 THEN
c = c + 100;
ENDIF;
IF b1 == 330 THEN
c = c – 100;
IF s == 1 AND b1 > 499 AND b2 <= 500 THEN
b2 = b2 + 10;
ENDIF;
IF b2 == 170 THEN
f = f + 100;
ENDIF;
IF b2 == 180 THEN
f = f – 100;
ENDIF; IF b2 == 320 THEN
c = c + 100;
ENDIF;
35
IF b2 == 330 THEN
c = c – 100;
IF s == 1 AND b2 > 499 AND b3 <= 500 THEN
b3 = b3 + 10;
ENDIF;
IF b3 == 170 THEN
f = f + 100;
ENDIF;
IF b3 == 180 THEN
f = f – 100;
ENDIF;
IF b3 == 320 THEN
c = c + 100;
ENDIF;
IF b3 == 330 THEN
c = c – 100;
ENDIF;
IF b3 >= 499 THEN
