دانلود کتاب برنامه‌نویسی کاربردی PLC برای مبتدیان -راهنمای عملی برای یادگیری برنامه‌نویسی PLC با CODESYS

At the outset, I would like to briefly describe why I decided to write this book. Upon assuming the position of Head of Electrical and Software Engineering, one of my responsibilities was to recruit new team members in our company. During the job interviews, I realized that young engineers, especially fresh graduates, did not fully understand what it means to work as a PLC programmer. Despite their well-developed academic knowledge, they lacked practical experience. While this may seem normal – to seek candidates with practical skills, you need to look for candidates with experience – it turned out that this approach was flawed. I had the opportunity to hire someone with five years of experience, but after two years, it became clear that this job was neither desirable nor performed successfully by the candidate. It is worth emphasizing that not everyone has the predisposition for this profession, despite all declarations regarding equality and equal opportunities. The idea of writing this book arose two years after assuming the aforementioned position. My goal is to support young people who would like to find out what the job of a PLC programmer really entails. During conversations with other people, the question about my daily duties often arose. When I mentioned that I am a PLC programmer, I was often mistakenly associated with the IT industry. In reality, most of my work involves sitting in front of a computer and programming, which may lead to such conclusions, but this is just the tip of the iceberg. I often had to reject candidates in job interviews because they simply did not fit the position. In such situations, I always wondered what motivated them to apply. I began to consider my beginnings in this job and recall how it all started. As a self-taught practitioner, I immediately started programming PLCs on projects under the guidance of my senior colleague at work, who introduced me to the world of PLC controllers. Together, we visited various facilities, started up installations, and completed projects. He was incredibly helpful, answered my questions, and constantly challenged me. His approach to the profession significantly shaped me because he was my authority and mentor in this field. His support and guidance played a crucial role in my professional development. Among the Star Wars fans in our company, due to this relationship, I began to be called his Padawan. In the meantime, I turned to books, searched the internet, and participated in various thematic forums. Starting my journey with SIEMENS controllers, I naturally came across a forum for products of this manufacturer. However, during my career, I did not come across any book that presented a practical approach to this profession or even just programming. Although there are many publications on this topic, when I reached for subsequent titles describing the construction of PLC controllers or discussing input/output modules, practical guidelines on configuration and programming in a real engineering environment were often lacking. It was precisely this gap that prompted me to decide to write this book.
