Now
we
come
to
the
Third
Industrial
Revolution
.
Riding
on
the
success
,
the
inventions
,
the
advancements
in
the
first
two
industrial
revolutions
,
the
Third
Industrial
Revolution
is
computerization
but
hang
on
not
just
about
automation
but
it's
more
about
flexibility
,
adaptability
,
reliability
and
more
.
people
is
needed
to
accomplish
many
of
the
work
.
And
very
strangely
in
this
particular
industrial
revolutions
,
no
new
skilled
or
unskilled
workers
position
is
created
.
Automation
is
common
at
the
basic
level
the
manufacturing
processes
in
plants
and
factories
.
More
about
the
Third
Industrial
Revolution
is
often
the
digital
revolution
and
of
course
it
encompassed
the
use
of
electronics
and
IT
to
further
automate
production
.
It
really
started
in
the
1960s
but
some
authors
also
quoted
70s
,
80s
or
some
even
marked
to
start
in
the
90s
.
The
advancement
of
technology
from
analog
,
electronic
and
mechanical
devices
to
digital
technologies
enable
storage
,
retrieval
,
transmission
,
comparison
,
computation
,
connection
,
reliability
and
accuracy
and
more
,
provides
a
myriad
of
potential
opportunities
people
to
designed
and
developed
different
types
of
tools
and
products
.
The
digital
revolution
also
the
beginning
of
the
information
era
.
Information
becomes
a
very
important
entity
in
organization
.
In
this
industrial
revolution
era
,
two
things
:
,
the
PLC
the
programmable
logic
controller
is
an
industrial
digital
computer
of
a
human
interface
and
it
is
used
to
define
control
,
diagnose
,
rectify
problems
in
manufacturing
processes
;
the
second
thing
is
the
internet
,
started
as
the
ARPANET
the
US
Department
defends
back
in
1969
to
1990
.
it
was
the
first
tcp
/
ip
network
in
the
1980s
the
first
generation
of
cell
network
and
force
tonight
is
the
world
wide
web
and
so
forth
and
today's
internet
web
2
.
0
everything
else
is
also
based
it
.
These
two
things
the
PLC
and
the
Internet
are
the
key
technologies
driving
the
advancements
in
the
Third
Industrial
Revolution
and
so
they
did
very
very
successfully
of
course
.
Scalability
of
automation
and
control
with
repeatability
and
reliability
enable
cost
and
fast
productions
which
ultimately
benefits
societies
and
all
human
beings
on
earth
.
As
I
said
earlier
you
know
-
interestingly
enough
,
no
new
unskilled
factory
worker
position
is
being
produced
in
this
revolution
the
first
two
.
Given
that
the
PLC
the
programmable
logic
controller
is
such
a
key
enabler
in
the
Third
Industrial
Revolution
,
I
thought
you'll
be
interested
in
once
again
have
a
look
at
this
short
video
taken
from
YouTube
that
described
the
next
level
of
details
about
the
PLC
.
I
hope
you
enjoy
it
.
A
programmable
logic
controller
or
PLC
is
simply
a
special
computer
that
is
programmed
to
control
certain
processes
in
industries
petroleum
steel
or
automotive
every
PLC
is
composed
of
three
main
parts
:
input
,
CPU
and
output
.
Suppose
that
we
have
an
electrical
motor
and
a
push
button
we
want
the
motor
to
turn
on
the
button
is
pressed
.
When
the
button
is
pressed
again
,
we
want
the
motor
to
turn
off
.
This
function
is
similar
to
the
function
of
the
power
button
on
your
TV
remote
.
do
this
,
we
must
first
write
a
program
for
this
operation
on
a
computer
and
then
download
it
to
the
CPU
.
Then
we
connect
the
switch
to
the
input
and
the
motor
to
the
output
.
Now
we
press
the
button
,
an
electrical
signal
be
sent
to
the
PLC
.
The
PLC
input
will
deliver
this
signal
to
the
CPU
but
first
must
present
it
in
a
format
that
the
CPU
can
process
.
Why
?
Because
the
CPU
is
a
computer
system
and
cannot
process
the
raw
electrical
signal
.
The
CPU
will
process
the
data
received
and
send
the
result
to
the
output
.
The
output
turns
the
data
a
raw
electrical
signal
again
and
applies
that
to
the
motor
and
turns
it
on
.
Now
if
we
press
the
button
again
the
process
repeats
and
the
motor
will
turn
.
