PLC Coding in 2019: Beginner’s Guide and Introduction to Programmable Logic Controller

If you are interested in learning more about the Programmable automated controller or Programmable logic controller but don’t know where or when to start, this article might be what you need, a PLC programming for beginners guide. In this article, we will talk about the introduction to PLC and PAC, the history, how they work and their components.

After reading this, you will be able to understand, know, and identify the primary components of a PAC and a PLC system, have a basic understanding of the function and purpose of programmable logic and automated controller. So, without further ado, let’s jump right into the introduction of PLC and PAC.

Introduction

PLC or programmable logic controller is industrial computers with modular components that are designed to automate a customized controlling process. PLCs are sometimes used in industrial plants and factories to control the machine, pumps, fans, circuit breakers, motors, and other machinery. To further understand the purpose of programmable controllers, we need to look at the history of the PLC and PAC.

History

Industrial and factory automation began long before PLCs was even thought of. During the 1900s or the start of the industrial revolution, automation was customarily done by intricate electromechanical relay circuits. But the number of wires, relays, and space that is needed to make even simple automation was challenging.

Hundreds, if not thousands of relays are necessary to run and automate a factory process. And if there’s something in the logic circuitry are needed to be changed, that would be a big problem. On a basic level, the electromechanical relays work by magnetically opens or close the electrical contacts when the circuit coils of the relays are energized.

They are essential devices and still plays a big part in the automation of industrial machinery. At the start of 1968, the first programmable logic controller was first introduced to replace the complicated relay circuits in the factory and industrial plants.

The PLC and PAC were designed to make sure that the programmers, technicians, and plant engineers that are already familiar with the process can easily program the system with their logic and control schematics. Since its conception, the programmable controllers have been programmed using a series of ladder logic that is designed to copy the control circuits schematics of the older automation system.

The ladder diagram looks like a central control circuit where the power flows from left to right through the closed contacts that energize a relay coil.

Ladder logic sample

As you all know, ladder logic is like a simple control circuitry schematic where the input sources like the push-button, switches or the proximity sensors are shown on the left side, and the outputs are displayed on the right side. The ability of the PLC and PAC to program difficult and intricate automated processes using an intuitive interface like a ladder logic made the change from relay logic to a programmable logic controller much more straightforward for programmers, technicians, … Read More

How Can Blogging Help You Grow Your Home Business?

You have probably heard about the term blog that uses the combination of terms web and log, and after a while, it was shortened down to the well-known word that most of us use daily: blog.

It started in the ‘90s, and at the very beginning, they were online diaries where people would provide personal information and accounts of their lives.

During that time, blogs were built around websites that were uploaded and updated manually, which means that some bloggers were not that significant because only tech-savvy people could blog when compared with today.

Blogging is also a great marketing strategy that will help you improve your home business. You should visit sites like https://qualityguestposts.com/ to help you check places that will provide you with the possibility to publish high-quality blog posts that will promote your business.

After platforms such as Blogger and WordPress entered the market, finally, blogging was put in the general public, and even people without programming knowledge could use it with ease.

Difference Between Blogs and Websites

The most significant difference between blogs and website is the amount of visitor engagement and site owner. Blogs are often combined with social media since visitors can easily talk with the owner and leave comments.

Before blogging, visitors had to sign guest books when they entered the website because no technological method would allow them to communicate with others through the site.

Another factor that differs blogs from websites is the updating frequency since most websites tend to be static and content inside doesn’t change too often. On the other hand, blogs are similar to news sites, and they are frequently updated with fresh and unique content.

Since most of us are using ad blockers that are reducing our ability to engage in different commercials and ads online, marketers found a way to get past that and to implement promotional perspective by using blog posts and that particular type of content.

Blog Marketing

We can say that blog marketing is the category within content marketing, but in this particular post, we will talk about it specifically. It is a process that will help you reach the target market through the use of a blog and the content on it.

In initial moments, business owners wanted to make blog separated from their websites, but nowadays, you can easily integrate both of them into one platform so that you can manage everything without losing the exceptional amount of time.

That also makes it easier for visitors to access you. Most businesses are using blogging platforms such as WordPress for both blog and website design, and since blogging increased in popularity, most people started their businesses from blogging.

Benefits Of Blog Marketing

The main idea of blogging is perfect for marketing purposes because the goal is to present a new content that will continuously try to draw more people back and to offer a different perspective so that they can interact … Read More
