Mastering programming requires consistent practice, much like preparing for an exam. The best way to improve is by working on real projects or studying examples and actually writing and debugging code. When I first started learning PLCs, I worked on simple but effective examples such as a marquee display (which can be implemented in multiple ways), traffic light control (involving timing cycles for red and yellow lights), elevator control (handling multi-floor priority responses), and constant pressure water supply systems (using closed-loop PID control combined with pump rotation time-based startup). The more you practice, the faster you'll progress.

While hands-on experience is the fastest way to learn, it's important to have a solid foundation first. Most automation companies specialize in specific industries, so it's crucial to understand the general process of that industry, the equipment used, and the corresponding electrical packages. Learning from predecessors' examples is highly recommended. If possible, working under someone experienced is ideal. If not, starting with small projects—like standalone equipment from Taiwan—can help build your skills gradually. These projects cover a narrower range of knowledge, making them easier to grasp. Once you're comfortable, you can move on to more complex systems and eventually master the field through continuous practice and application.
