Published by LogicHobbyist Automation Lab — From zero to first working program. No expensive hardware required. Learn the scan cycle, ladder logic, and how to practice for free. ⚡ Before you start: A PLC is not an Arduino. It is designed for reliability and real‑time determinism. The mindset is different: you are wiring logic, not … Read more
Published by LogicHobbyist Automation Lab — A complete guide for controls engineers and electricians. Understand the difference, wiring rules, global standards, and how to avoid costly mistakes. One of the most common points of confusion in industrial automation is the difference between sourcing and sinking digital I/O. Mix them up, and your sensors won’t work, … Read more
🎓 Beckhoff TwinCAT 3 Advanced Industrial Masterclass This practical guide is part of an interconnected, step-by-step course designed to transition developers into high-tier B2B PLC engineering. Every lesson builds directly upon the real-time core configurations, hardware definitions, and Structured Text rules established in the sequential tracking sessions. 🚀 Current Milestone: Lesson 1: Environmental Setup & … Read more
In the beginning, a single programmable relay like the akYtec PR200 is often enough to handle a small machine. But as a business grows, so do the requirements. You may start with 8 inputs today and find you need 40 tomorrow. In industrial B2B environments, we don’t replace the controller when we run out of … Read more
🏗️ Article Draft: Logic Gates 102 In Logic Gates 101, we covered the basic “building blocks.” However, real-world automation often requires more nuanced decisions—like ensuring two buttons aren’t pressed at once, or confirming that two sensors perfectly match. 1. The XOR Gate (Exclusive OR) The XOR gate is the “Interlocking King.” It only outputs TRUE … Read more
In the digital world, everything is a 1 or a 0. In the industrial world, those 1s and 0s are 24V signals and Relay States. Whether you are using akYtec ALP, Ladder Logic, or discrete transistors, you are using Logic Gates. Understanding these gates is the difference between “guessing” a circuit and “engineering” a solution. … Read more
An automation system is only as good as its interface. In this lesson, we transition from internal logic to the Human-Machine Interface (HMI). We will focus on how to display process data and how to build a multi-screen menu system that remains intuitive for plant operators. 1. Adding Variables to the Display To show data … Read more
In industrial automation, reading a sensor is only half the battle. The real challenge is converting a raw electrical signal into a value that humans—and machines—can actually use. This lesson covers the industry-standard 4-20mA current loop and how to scale it within akYtec Logic Program (ALP). 1. Why 4-20mA? (The B2B Standard) While hobbyist projects … Read more
In the industrial world, data is just as important as logic. Managers need to know how many parts were produced, how many cycles a machine has completed, and when it’s time for maintenance. In this lesson, we will implement the CTU (Count Up) block to track a proximity sensor and display that live data on … Read more
Timers are the heartbeat of industrial logic. In this lesson, we cover TON (On-Delay) and TOF (Off-Delay). In industrial automation, timing is everything. Whether you are delaying a motor start to prevent a power surge or keeping a safety fan running after a machine stops, you need timers. In this lesson, we will cover the … Read more
