Where PLC Programmers Go to Grow

Stay up to date with our most recent informative videos and blogs on PLC programming and automation

 

What is Fieldbus?

Fieldbus isn’t really one thing but more of a collection of things. Fieldbus is a group of protocols that are used in the industrial arena. The Fieldbus protocols have been standardized as IEC61158.Basically, Fieldbus works on a network that permits various topologies...

What is a Control or Function Block?

Have you ever heard of a control block? How about a function block? Different programmers call them by different names, and that can be confusing, but I hope to clear things up for you in this article. So, what exactly is a control or function block? They give us...

What is DeviceNet?

DeviceNet is an application-level protocol used in the automation environment. It is a communication tool that allows you to logically talk between a PLC (Programmable Logic Controller) and many control devices, such as motors, conveyors, flowmeters, level sensors,...

How does Modbus Communication Protocol Work?

In the previous video, you learned about what Modbus communication protocol is and the types of Modbus communication used in the industry. Now, as promised, in this video you are going to learn about How Modbus communication protocol works between devices. 1. Modbus...

What is a PID Controller?

Today you will learn about PIDs. Specifically, what they are and when do we use them with automation and PLCs. So what is a PID controller? PID is an acronym that stands for Proportional, Integral, Derivative. If you need to keep something constant, like a temperature...

What is Modbus?

In the real world of the device to device process automation communication, a dialogue or conversation between devices occurs systematically, in many cases, over different types of communication networks and in different languages. Modbus as an "Open Protocol"...

What are the Most Popular PLC Programming Languages?

There are 5 languages that are all a part of the IEC (International Electrotechnical Commission) Section 61131-3 Standard. This IEC Standard allows some ground rules that standardize PLC’s and their languages. Let’s take a deeper look into all these PLC Programming...

What is the Difference between Profibus and Profinet?

Profibus and Profinet are industrial communications protocols used extensively by Siemens control systems. While they may sound similar, don't let the names fool you! Profibus and Profinet are very different protocols that use different cables and connectors. Let's...

How to Determine the Motor Size for Your Project?

In this lesson, we will continue the discussion on the topic of motion control. All of us at RealPars, hope you have been following our previous lessons on motion control and have begun to benefit from these lessons. Now you will apply your base knowledge of Servo and...
