Hi Everyone! How are you doing, my friends? Today I bring a crucial topic for PLC programmers, technicians and engineers. We have been working together for a long time using ladder logic programming. We have completed together dozens of projects from real life and industry. One day I was thinking about what we have done in this series of ladder logic programming, and I came across that I missed talking about one essential topic ever. You know what? It’s the PLC troubleshooting and online debugging! After writing a ladder logic program for the project, you can imagine it should operate from the ...
Hi, my friends and welcome back. I am happy to meet you again with a new tutorial of our PLC ladder logic programming series tutorials. Today we will complete what we started the last tutorial on the Elevator control project. We have a bunch of duties to complete together today. So let’s save time and jump into work immediately.
Project description:
Figure one shows the details that might help me describe the project between our hands. We have an elevator car that travels up and down and can stop on one of four floors based on the passengers’ requests. We have 6 push buttons on the wall next ...
Hello, my friends and welcome back with one new tutorial of our ladder logic programming series. Today I am bringing one exciting project which you can see everywhere, in your home, work, and public places, which is an elevator. We will design a solution using plc ladder logic programming, which drives the elevator. Our elevator is composed of 4 floors and has all capabilities of large-scale elevators. So let’s get started and save time and jump into our tutorial.
Elevator Project
As you can see, Everyone figure 1 depicts the complete scene of the project and tells that the elevator we will ...
Hello everyone, and welcome back with a new tutorial in our ladder logic programming. Today we will continue the bottle line production line using ladder logic programming. Let me remind you, everyone; we have seen how to utilize the bit shift left instruction BSL to save the data that describes the state of a bottle, including the present state, size state, either large or small size and the excellent and broken state as well. And also we utilized these states to energize the large bottle and scrap solenoid to divert the bottles to the appropriate position and conveyor. At the end of the day, ...
Hi, my friends, and welcome back to enjoying together learning and practicing PLC ladder logic programming with a new project from the actual industry. Today my friends, we will continue the bottle line project to complete the capping and filling of the bottling line. As usual, we will describe the requirements as the clients ask us to do. Then we list all the inputs and outputs we will use to make our design work. Afterward, we write the ladder logic program into two sub-tasks. We make one to perform the filling and the second for the capping process. So, without further delay, buddies, let’s ...
Hello, my friends, again we are back and enjoying one of the new tutorials in our ladder logic programming series. The tutorial we are here to present comes with a new project: dual compressors management using PLC. In that very project, you are going to learn how to divide the process between two actuators aiming to prolong the lifetime of the equipment and fulfill the processing requirements. as we used to do every tutorial, will go through the project. Understand the requirements, and design for the solution. And then code the ladder logic program of the solution and for sure enjoying simul ...
Hello friends, we are going to learn and practice together one project from the industry. It is the bottle line production in which many processes are happening, including but not limited to filling, capping, and conveying from the start point where the bottles get in the line to the end point where the bottle gets out from the line. In the process, many concerns and restrictions must be addressed, like the bottle size, length, broken status, pretty full or empty, etc. So we have a lot to learn, program, and test right here in this project. Let’s jump into work and enjoy completing such an exc ...
Hello friends, welcome back to our tutorials on PLC ladder logic programming. Today we will talk about batch process control and take one project from our factory to understand, implement, and simulate. So without any further delay, let’s jump into the tutorial by asking what is batch process is if it is different from other online processes. Well! The batch process is defined as a process that starts by operating continuously till the end of the cycle without any interaction with the users. For you guys, it’s cool to know that most of the processes you might meet in the industry of batch-type ...
Hi, my friends, and I hope you are doing great today! We have today one interesting topic that you have seen everywhere you go, but you might not notice it! That is what the so-called binary coded decimal (BCD) is. So what’s that? Well! When you are waiting for your turn at the front of a wicket in the bank. You see 7-segmented displays that show numbers in digits. So how do these counter displays work? The BCD is the idea behind how these displays work. Numbers can be represented in many formats. Some of these formats are readable for the public which is the decimal pr the digits 0, 1, 2, .., ...
Hi, my friends. Welcome to share a new tutorial in our ladder logic programming series. Today we will discuss counters in ladder logic programming using an expert’s view. So let’s wear the glasses of an expert in ladder logic programming and look deeply into counters, the types of counters, their variables and bits. In addition, techniques of using counters to solve a different kinds of problems that need counting. And without questions like every time, we will enjoy practicing programming and simulating all about counters. So with no further delay, let’s jump into our tutorial and nail that c ...
