Master Parallel Logic: Break Free from Sequential Thinking
Nov 26, 2025
Beginners accustomed to sequential programming may find it challenging to break away from the procedural mindset and design their logic in parallel. Ladder logic is solved from left to right, top to bottom. The output from the previous rung is available for the next rung to use.
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.
