1How PLCs Affect Our Everyday Lives?
PLCs, commonly referred to as programmable logic
controllers, are reliable industrial electronic
devices for various mechanical systems and
application control. How widespread are PLCs,
and why are they so crucial? Well, PLC systems
can be found everywhere in our highly
technological world, from industries to office
spaces to the traffic signals on the streets.
Because they are so effortlessly and
unnoticeably incorporated into our daily lives,
PLCs are at the core of the control of numerous
vital technologies that most of us dont even
give a second thought to. In the following
examples, PLCs are used to control mechanical
systems in everyday life
2Road Traffic Signals Without traffic signals,
its challenging to imagine our modern world.
People around the globe are familiar with and
use those three streetlight colours. Since its
initial use for traffic control in 1926 in
London, England, the PLC has had a lengthy
history in large cities and little villages
worldwide. These traffic lights, which we
frequently take for granted, are monitored and
managed by PLC hardware and software, which
operates stably and smoothly around the clock,
365 days a year. Have you ever observed that
travelling during rush hours on a busy street is
a completely different experience than during
times of low traffic? How would it impact the
flow of automobiles if a pedestrian at an
intersection pressed the crosswalk button? When
traffic lights enable them to drive through an
intersection, are emergency vehicles genuinely
seen? Traffic flow is coordinated and managed
using emergency vehicle transponders, sensors,
and plc circuits to control the traffic lights,
enabling more prompt and focused rescue
assistance. The Automatic Car Wash Gas stations
sometimes come with automatic car wash systems in
crowded cities with heavy vehicle traffic. The
water mixed with cleaning agents will blast the
cars surface as you move around inside the
touch-free carwash, and the wipers will rotate to
scrape the surface. Every step of the process is
calculated and meticulously managed, down to how
many litres or gallons of soap are used and how
long those tall revolving wipers spin. PLCs
entirely automate these labour- and time-saving
services, requiring only a button press at the
entrance from humans. The Elevator The elevator
business is expanding. No matter how little or
large, an elevator is found in every multi-story
building. But there are chances it can go in the
wrong direction sometimes. Have you ever
wondered who or what is causing this? To give you
a hint, an established software now running in a
PLC recognises the various floors that are making
elevator requests and directs the elevators in
the appropriate direction. The lifts PLC is
loaded with these programmes, which are
collections of ladder logic instructions.
Typically, the controllers are not
3situated inside the elevator but at a specified
spot on the buildings top or in a neighbouring
control room. The majority of elevators use PLCs
to programme and control them. These PLCs are
set to take the fastest path through pending
button calls and base their directional
decisions on that. Automatic Doors For a long
time, the automated door swinging open was
nothing less than a source of injury.
Fortunately, modern PLC controls have improved
built-in sensors on both sides of the door to
stop this from happening. There are numerous ways
for an automatic door to work, but in general,
they do so by employing a detector, such as one
that detects when a light beam is disrupted, to
identify objects in front of or between the
doors. Conveyor Belts The conveyor belts in
supermarkets and shopping malls allow the
projects to move along the line, making it
easier for the cashier to carry out the billing
process. Imagine the inconvenience if a worker
wasnt there to help regulate the belt and make
the checkout process quick and easy. In
airports, larger conveyor belts move people or
place luggage on luggage carousels until the
owner picks it up. Even enormous conveyor belts
exist to move building supplies. Due to their
practicality and consistent motion, conveyor
belts are also utilised in most production
facilities. Roller Coasters Although roller
coaster rides can be scary, the thrills can be
unparalleled. In roller coasters, the PLC
control is typically used to raise the ride
before the major drop. Additionally, it serves as
a safety measure to prevent cars from turning
around. It wouldnt be as exciting to fall as
moving forward on the steep fall. These days,
PLCs regulate equipment that supports our
high-tech lifestyles almost wherever you look.
Our lives are made better by the strong and
dependable control systems they offer us, from
traffic signals to roller coasters. The
maintenance and support of these systems are
4done by PLC specialists, who offer a vital
service that keeps us safe and moving through our
busy lives. FAQs - 1. What Is Certificate III
