Here are the top 7 problems and concepts beginners struggle with using ladder logic (Ladder Diagram). Ladder logic is a programming language used in PLCs, and it is based on the graphical representation of electrical relay logic circuits. Many beginners struggle with ladder logic because it requires a different mindset than traditional programming languages like C++, Python, or Java.
We will look at the seven common issues beginners face due to a lack of understanding of ladder logic. Stick around until the end to see the bonus problem that is not well understood. Let's get started.
