The document discusses SCADA (supervisory control and data acquisition) systems. A SCADA system monitors and controls remote equipment via coded signals over communication channels. It performs functions like data acquisition, communication, monitoring, and control. A SCADA system consists of hardware components like master terminal units and remote terminal units, and software for data acquisition, control, user interfaces, and alarms. SCADA systems have evolved through generations from monolithic to distributed to networked systems and now include internet of things capabilities. Examples of SCADA system uses include industrial processes, infrastructure, and facilities. The document also discusses the Ignition SCADA software platform.

2. WHAT IS SCADA?
• SCADA (supervisory control and data
acquisition) is a system operating with coded
signals over communication channels so as to
provide control of remote equipment (using
typically one communication channel per
remote station).

3. WORKING PROCEDURE OF SCADA
SYSTEM
• The SCADA system performs the following
functions:
Data Acquisitions
Data Communication
Information/Data presentation
Monitoring/Control

4. • A SCADA system can be implemented with the
hardware and software components that
constitute a whole SCADA system.

5. • HARDWARE COMPONENTS:
Master Terminal Unit (MTU)
Remote Terminal Unit (RTU)
Communication Equipment

6. • SOFTWARE COMPONENTS:
Data Acquisition and Processing
Control
Man machine interface
Alarm handling

7. SCADA SOFTWARE
• SCADA systems used to run on DOS, VMS and
UNIX.
• However in recent years, all SCADA vendors have
moved to NT and Linux platform.
• SCADA master computers typically run on top of a
third party operating system.
• Nearly all SCADA products run on either a UNIX
variant or HP Open VMS, although many vendors
are beginning to provide Microsoft Windows as a
host operating system option.

9. • SCADA systems have evolved through four
generations as follows:
First generation: "Monolithic"
Second generation: "Distributed"
Third generation: "Networked"
Fourth generation: "Internet of Things"

10. EXAMPLES OF USE
• Industrial processes include manufacturing, Process control,
power generation, fabrication, and refining, and may run in
continuous, batch, repetitive, or discrete modes.
• Infrastructure processes may be public or private, and include
water treatment and distribution, wastewater collection and
treatment, oil and gas pipelines, electrical power transmission
and distribution, and wind farms.
• Facility processes, including buildings, airports, ships, and
space stations. They monitor and control heating, ventilation,
and air conditioning systems (HVAC), access, and energy
consumption.

11. Ignition HMI/SCADA Software
• Ignition by Inductive Automation® is an
industrial automation software platform that
many businesses and organizations have
switched to for their HMI/SCADA needs.

13. • Here are a few reasons why more enterprises are
choosing Ignition:
 Ignition uses modern IT practices that make it
compatible with current SCADA system components.
 Its unique licensing model lets users pay a flat fee
based on the number of servers. Other SCADA vendors
typically charge per client or per tag, but Ignition offers
unlimited clients and tags.
 Ignition is web-deployable: it can be downloaded and
installed in a few minutes, and clients can be launched
or updated instantly

14. • Ignition has been installed in thousands of
locations in over 70 countries since 2010. Its
powerful and robust nature allows SCADA
system integrators to reach the demands of
their customers while costing less than other
SCADA software solutions.

15. CONCLUSION
SCADA systems are most advancing computer
application, so even once the SCADA system is
installed its up gradation can be easily done.
So SCADA system is to be implemented in all
the power industries.
