Explanation
In this example, metal plates are being transported. The position of a
plate is detected by a proximity switch located next to each belt segment.
As
long
as
the
metal
plate
is
within
the
detecting
range
of
the
switch,
the
programmable
controller
issues
a
control
output
that
causes
the
motor
of
the next conveyor belt to work. When the metal plate moves out of the
detection range of the proximity switch, the timer is activated and when
the set time has elapsed, the motor of the first conveyor belt stops.

Operation
Since
the
metal
plate
is
detected
by
sensors
3,
2,
and
1
in
that
sequence,
the
first
input
signal
in
the
ladder
diagram
comes
from
sensor
3
(input
0002).
When
input
0002
turns
on,
output
0501,
corresponding
to
motor
2,
is
issued
by
the
C20.
When
input
0001
turns
on,
motor
1
is
started
by
output
0500.
The
operation
of
motor
2
only
lasts
2
seconds,
the
time
required
for
the
metal
plate
to
travel
to
the
next
conveyor
belt.
Thus
the
motors
operate
only
when
they
are
actually
needed.
