Content of a PLC Technical Training 2018

As a professional and have plans of working under a well-known and a reputable manufacturing company means that you need to be a competitive PLC operator or programmer. It is not enough to be an engineer or a machine operator. You need to have a specific skill that focuses on operating a PLC or a Programmable Logic Controller. Working in this kind of industry today would be very different and quite complicated due to the high standards and advanced technology that these companies are using.

So, you need to know not only about how you are going to operate a particular machine used in manufacturing of various products. You must also know how to troubleshoot these machines and make sure that it will function well. If you do not have enough experience and skills in doing such, then it would be difficult for you to maintain the operation of the factory. This is something that you must learn to avoid, so that your sales as well as the company’s reputation won’t be affected.

Now, if you are in need of a technical training about PLC, then it would be ideal for you to check out and inquire about various PLC trainings and programs that can help you enhance and upgrade your skills. Do you know that having sufficient knowledge and skills in PLC means that you can help a lot in the manufacturing industry? So, if you are interested to work with those companies, then you must start attending your training as soon as possible. We have here some information about the contents of the training that you need to learn.

Understanding PLC

A Programmable Logic Controller or PLC, is a computerized control system that is used in different manufacturing industries to help in monitoring the status of the machine or system, which is in-charged with the production. Without enough knowledge and understanding of the input, the process and the output, then you will find it uneasy to operate the device and keep things working right.

A PLC has its own Operating System or OS and this is what you need to also understand. This OS is specifically designed for a PLC. Now, if you will not undergo a certain training, then how can you use this operating system, right? If you are going to read and study about it on your own, then it will take long time to master it.

Aside from that, you must also know about the hardware parts or components of this device as well as its function. Studying these need an exposure to these parts. In such a way, you will know how to replace or repair these parts when needed. You may get more info about PLC hardware online.

The Programming Language

In order to optimize the use of this controller, you must be able to understand the language that a PLC use. This is the Relay Ladder Logic or the RLL, which is actually built as simulated relays. This language may be edited through a Sequential Function chart to represent signal as well as the flow of data, Functional Block Diagram, Structured Text for programming with the right syntax, Instruction List that serves as an assembler and Continuous function Chart. And then, now that we already have added features to the PLC, such as counters and timers, the programming language has also expanded.

A particular software is used to program a PLC. The program is usually presented through graphic forms to show how the logic is formed. The software is usually installed on a remote computer. And then, through this software, the operator would be able to back up the system as well as uploading, downloading and restoring data.

The Core Areas of a PLC

The power supply and the rack are one of the core areas of a PLC. The rack is the part of the PLC that holds all the other parts. It may vary in size, depending on how many modules are needed to fit in the rack. You can find the backplane in the rack. It is responsible in allowing communication of various cards and the CPU. Of course, for the PLC to function and start its operation, we have the power supply connected to the rack. You can read more about the power supply needed for a PLC system at

The Central Processing Unit or the CPU is considered as the brain of the PLC system. It comes with a module that is usually found near the power supply. It is built with various types, depending on the complexity of the PLC system that a manufacturing company requires. The CPU has a memory chip, microprocessors and circuits. When the CPU is in a programming mode, it means that the PLC is accepting logics that was downloaded from a remote computer. While in the run mode, it means that the system is executing and operating various processes.

The Input/Output or I/O Section refers to the physical connection between the PLC and the manufacturer’s equipment. It has I/O cards used for the logic needed. The input devices could either be a digital device like buttons, switches and sensors or an analog device, such as flow meter, transducers and thermocouples.

PLC Operation

Another essential part of your PLC Training is to learn about how you are going to operate a PLC System. Basically, you need to understand three processes. The first process is to scan or read data from an input device. In this process, the CPU of the PLC system must also read the data and verify the reliability of the input device. Therefore, it only shows that the CPU takes the preliminary step, so you need to read more about its functions.

The next process is to execute the logic of the program. This will only happen, when the input is right. The system will translate this input to a language that the program can understand. And then, it will send the data to be prepared as an output.

And then, the final process is to update and write the data to the output device. Of course, this would be after executing the operation of the PLC system. That will happen after the system converts the operation to an output.
