In the previous post Logical Gates in Ladder Logic for PLC, we had an overview of what is Ladder Logic programming and we have also implemented three basic Logical gates in Ladder Logic form. Today, we are gonna have a look at some complex Logical Gates in Ladder Logic for PLC. So, I hope till now you guys have basic knowledge of Ladder Logic and can implement complex logical gates in it. If you haven't read the previous post then must read because without that knowledge you won't understand this post.
In today's post we are gonna implement few complex logical gates. Its not gonna be much difficult if you have the basic concepts. I am just pointing out few important points here. While implementing any gate in ladder logic, always consider rung as ...
Hello friends, I hope you all are fine and enjoying good health. Today's tutorial, as the name shows, is on Introduction to PLC. PLC is an abbreviation of Programmable Logic Controller. Recently I worked on a project in which I have to design a Automated coffee Mixing Machine Using PLC. It worked quite good and I had a great time while working on it. After completing that project, it occurred to me that I haven't posted any tutorial on PLC. So I thought of starting this tutorial. This tutorial is not gonna cover in single post so my plan is to divide it in parts.
Today. I am gonna give an overview about PLC. We will have a look on basics i.e. what is PLC? Why we use PLC instead of microcontroller like Arduino or PIC Microcontroller? What's its adv ...
Hello everyone, I hope you all are doing great. In today's tutorial, I am going to share the detailed fIn the previous post, we have seen Introduction to PLC, which was quite simple and has the basic introduction to PLC. To day we are gonna have a look at Getting Started With Ladder Logic For PLC. Ladder Logic, also named as Ladder Logic Programming, is the programming language for PLCs. Its normally considered as the most difficult language among the engineers because of its complex structure, but if you ask me then I will say its the most interesting programming language.
Ladder Logic is different from the usual programming language of Microcontrollers like Arduino, PIC Microcontroller etc. Microcontrollers programming usually compiled from top ...
Hi friends, how are you doing? Today will integrate all of what we have learned so far in this series to build the first project based on ladder logic programming. Because we all are interested in industry, we pick one industrial project, Bottle Filling and Capping Projects, which is very common today. The problem we are going to solve today is bottle filling and capping. We have learned all basics of ladder logic including contacts and coils operation, logic gates, rising and falling edges, timers, and counters. So, today we will utilize all of these components to implement a complete ladder program of filling and capping problems.
Operation and Logic of Bottle Filling and Capping Process
For simplifying the operation of the process of filling and capping, fig. 1 shows the process flow ...
Hello friends, hope you all are having fun with your lives. Today, I am going to share links related to PLC projects. I have shared few PLC projects on my blog so here on the post I am gonna compile a list and will post all the PLC projects posted till now. I will keep on updating this list so stay tuned.
All the PLC projects posted here are completely designed by our team so if you wanna copy them then you are most welcome but do mentioned the link of respective project as a favor. Its not a very big list rite now but I am gonna update more projects real soon and will update the list. So, let's get started with PLC projects:
PLC Projects
Here's the complete list of PLC projects posted till now on our blog:

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 download moment 24/7. As usual, any system goes faulty one day. So we need to go through this matter, showing you how to find our PLC faults, troubleshoot, and go online with the PLC to figure out th ...
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 to the elevator door that can send requests to call the elevator. In addition, there is a control panel inside the elevator cabinet in which there are push buttons to request stations to reach floors ...
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 manage has four floors to visit. On the first floor, there is only one outer request to call the car from any floor above, i.e. from floor 2, floor 3, or floor 4. While on the second floor, there are ...
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, we have separated small, large, and scrap bottles. Today we are going to manage the scraping of the broken bottle.
Bottle line Scraping management
In each bottle line process, we have a common and ...
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 jump into the work.
Filling and capping project
Let me introduce the project as two processes we have been requested to implement here. We are filling bottle process in which we need to control the ...
