2. AutomationAutomation
Automation is basically a delegation of human control function to control
technical equipment.
Automation is the use of control systems and information technologies
reducing the need for human intervention.

3. It is a technology dealing with the
application of
• mechatronics
• computers
for production of goods and services.
Automation is broadly classified into
• manufacturing automation
• service automation

6. Automation ToolsAutomation Tools
Different types of automation tools exist:
DCS - Distributed Control System
HMI - Human Machine Interface
SCADA - Supervisory Control and Data Acquisition
PLC - Programmable Logic Controller
Instrumentation
Motion control

7. SCADA stands for supervisory control and data
acquisition.
It generally refers to an industrial control
system: a computer system monitoring and
controlling a process.
The process can be industrial, infrastructure or
facility-based.
Supervisory Control and Data Acquisition System refers
to a system that enables an electric utility to monitor,
coordinate, control and operate distribution components
and devices in a real-time mode from remote locations
with acquisition of data for analysis and planning, from
one central location

21. IMPACT of AUTOMATIONIMPACT of AUTOMATION
Automation has had a notable impact in a wide range of highly
visible industries beyond manufacturing.
Once-ubiquitous telephone operators have been replaced largely by
automated telephone switchboards and answering machines.
Medical processes such as primary screening in
electrocardiography or radiography and laboratory analysis of
human genes, cells, and tissues are carried out at much greater
speed and accuracy by automated systems.
In general, automation has been responsible for the shift in the world
economy from agrarian to industrial in the 19th century and from
industrial to services in the 20th century.

22. ADVANTAGESADVANTAGES
Accurate and consistent
information
Faster fault identification
Improved availability of system Increased Production

23. ADVANTAGESADVANTAGES
Reduced Cost Maintenance of Quality & Quantity
Improved Safety Conditions

24. DisadvantagesDisadvantages
The main disadvantages of automation are:
Technology limits: Current technology is unable to
automate all the desired tasks.
Unpredictable development costs.:The research and
development cost of automating a process is difficult
to predict accurately beforehand. Since this cost can
have a large impact on profitability, it's possible to
finish automating a process only to discover that
there's no economic advantage in doing so.
Initial costs are relatively high: The automation of a
new product required a huge initial investment in
comparison with the unit cost of the product,
although the cost of automation is spread in many
product batches
