WHAT is SCADA?
SCADA stands for
“Supervisory Control and
Data Acquisition”. SCADA is
a type of process control
system architecture that
uses computers, networked
data communications and
graphical Human Machine
Interfaces (HMIs) to enable
a high-level process
supervisory management
and control.
SCADA is a centralized system that monitors and controls the entire
area. This supervisory system gathers data on the process and sends
the commands control to the process.
SCADA systems
continuously monitor the
physical parameters
DATA
COMMUNICATION
It helps to communicate and
transmit a large amount of data
between MTU and RTU units
MEASURE
It measures the parameter
for processing
CONTROLLING
Online real-time monitoring
and controlling of the
process
DATA
ACQUISITION
It acquires data from RTUs
(Remote Terminal Units),
data loggers, etc.
AUTOMATION
It helps for automatic
transmission and
functionality
OBJECTIVES of
SCADA
MONITOR
Data Acquisition
Data
Presentation
The collected data is processed,
organized and presented for
system operators to make
appropriate response and
control decisions.
The collected data is transmitted
either spontaneously or in
response to a request for data to
some kind of upstream
consolidator or master.
Control
If control decisions are warranted
and the system supports output,
appropriate commands can be
dispatched to affect specific
operational or configuration
changes.
4 SCADA
FUNCTIONS
The collection of SCADA data
frequently involves some kind
of analog to digital conversion.
Networked Data
Communication
INPUT
Inputs (either digital or analog)
and output relays or electrical
signals that directly interface with
managed elements in the remote
sites.
RTUs are small computerized
units deployed in the field at
specific sites and locations.
HMI software is a computer master
station system that processes data
and allows a human operator to
manage and control the system.
The communications network
is what connects telemetry
and SCADA at your remote
sites.

WHO Uses
SCADA?
SCADA systems are used by
industrial organizations and
companies in the public and
private sectors to control and
maintain efficiency, distribute
data for smarter decisions, and
communicate system issues to
help mitigate downtime.
An example…
SCADA systems can be run virtually, which allows the
operator to keep a track of the entire process from his place or
control room. Time can be saved by using SCADA efficiently.
One such excellent example is, SCADA systems are used
extensively in the Oil and Gas sector. Large pipelines will be
used to transfer oil and chemicals inside the manufacturing
unit.
