Programmable Logic Controller - Problems with Solutions (Beginner Friendly)

If you are an engineering student or an automation enthusiast looking to learn PLC ladder logic programming, this guide will walk you through real-world examples. We’ll go step by step, starting with simple control mechanisms and then moving toward tank filling automation using sensors. By the end, you’ll understand how ladder diagrams are applied in industrial automation systems.

Programmable Logic Controller - Program Control Instruction(MCR)

An MCR zone in PLC programming refers to the section of ladder logic that is bracketed by two Master Control Reset (MCR) instructions—one to start the zone and one to end it. This zone allows you to control the execution of all rungs within it as a block, giving you the ability to enable or disable their outputs based on the condition set by the first MCR instruction

Programmable Logic Controller - Lets Solve a Sequential Problem

Lets try and solve a sequential problem in this blog post.

Programmable Logic Controller - Up Down Counter in PLC

Another key aspect in the PLC programming is the concept of the up down counter. This post covers the basics of it.

Programmable Logic Controller - Creating Timer Application in PLC

The timers are key part of any programming logic. The post here describes how to set it up with a PLC IDe. These were the experiments and records i did as a student. Posting it here as a blog content.

Programmable Logic Controller - Latch Application in PLC

The latch application, meaning latching of push button outputs are one of the most common use cases of the PLC Application. The following experiments demonstrates how that is implemented. These were the experiments and records i did as a student. Posting it here as a blog content.

Programmable Logic Controller - Introduction/Simple Logical Experiments

Following series of posts capture experiements done with the keyence logic builder to make programs for the Programmable Logic Controller devices. These are pretty basic experiments and anyone can follow it along. These were the experiments and records i did as a student. Posting it here as a blog content.

Demystifying the Finite Element Method: A Very Simple Truss Stiffness Matrix in Python

I dont recall how long ago i worked on FEM methods but found this basic program of stiffness matrix calculation in one of my older hard drive. So why go it to waste here is a brief blog on how FEM, a numerical technique can be approached. This technique breaks down a complex structure into smaller, simpler pieces called "finite elements." By analyzing these small elements and then reassembling them, we can understand the behavior of the entire structure.

One of the most fundamental concepts in FEM is the stiffness matrix. This matrix represents the relationship between the forces applied to a structure's nodes and the resulting displacement of those nodes. In a simple truss, which is a structure made of straight members connected at joints (like a bicycle frame), we can build a stiffness matrix to understand its behavior.

Let's take a look at a Python script that calculates the global stiffness matrix for a simple plane truss with three members.

Parsing an XML File in Java with SAX Parser

Parsing XML files is a common task in Java development, and a SAX parser is a popular choice for this purpose. The SAX parser is known for being faster and using less memory compared to the DOM parser. This is because the SAX parser doesn't load the entire XML document into memory or create an object representation of it. Instead, it uses callback functions to inform clients about the XML document's structure as it reads through the file.

This post will guide you through parsing an XML file using the SAX parser in Java, based on the provided examples.
