How to Become a PLC Technician: PLC Training, The Beginner's Guide
Manufacturing is changing in this country. As technology has evolved, so has the entire manufacturing industry. many companies have moved facilities off-shore, but the ones that remain or have since opened on U.S. soil look much different than the dark, grim factories of yesteryear. Today's manufacturing facilities often look more like laboratories than production plants.
Within this changing industry, there are many roles worth exploring. In this article we'll take a look at one of the lesser-known (but vitally important) roles of the modern manufacturing industry: Programmable Logic Controller (PLC). Although a position in the industry, PLC is also the name of a device used heavily in this role.
What is a Programmable Logic Controller (PLC) Device?
A Programmable Logic Controller (PLC) device is a miniature computer (having a microprocessor qualifies it as a computer) with a custom operating system built in. This device is used to control other machines used in the manufacturing process.
PLC devices use a system of sensors that read input data to tell them when an event needs to occur, and then signals output to make the event happen. The entire sequence occurs in real time and repeats in a loop until the input changes. The PLC device tells the machine what to do and when to do it. Think of a PLC device as the conductor of the manufacturing orchestra.
Where are PLCs used?
PLC devices replaced the old automatic controls used in manufacturing and other industries. These old controls were hard-wired relays that drove motor driven timers and rotary sequencers. Often one PLC device is used to replace hundreds of the old system devices.
Automobile assembly lines were the first manufacturers to embrace this new computer technology as a way to save time and cut costs when retooling for new models. Since their inception, PLC devices have been used to control machinery in countless industries. In modern industry, the PLC device controls a vast range of equipment. A small sampling would include:
- Manufacturing
- Travel
- Film
- Medical
- Agriculture
- Aerospace
What jobs are related to PLC?
With millions of PLC devices out there in such a wide array of industries, companies need personnel to program the little devils. These people are known as Programmable Logic Controllers (PLC). They control the controller! These individuals are trained in every function of these devices.
The role of a Programmable Logic Controller includes setting up electronic control systems for machines. This technical knowledge would require an understanding of electrical wiring, hydraulic systems, pneumatic systems, wiring schematics, and computer programming. PLC workers also must understand basic automation principles and use critical thinking to solve problems.
PLC workers keep the controllers operating to minimize interruptions. Responsibilities also include monitoring and reacting to all pertinent issues. At regular intervals, they may perform preventive maintenance on all equipment. PLCs also identify and facilitate repairs as needed.
In the PLC position, regular safety inspections and related duties are high on the list of priorities.
Education Required to become a PLC Professional
This work requires a background in electronics or a related field, and of course some instruction in either electronics or automation technology. Official certification or a degree is a must for many potential manufacturing organizations. Programs are available at universities, community colleges, and vocational schools that cover the basics.
A great university for PLC training will include opportunities for hands-on learning and practice, to better prepare students for life after graduation. If you're interested in becoming a PLC professional, look into educational programs with immersive learning, practice opportunities, and industry-standard equipment for student use. Some universities may even offer accelerated PLC training, so you could graduate sooner!
