The first step in learning PLC is to become familiar with electrical components, including understanding the names, specifications, performance, and uses of commonly used components, as well as their role and operation in circuits. In addition, it is also necessary to understand some basic electrical knowledge, such as voltage, current, resistance, capacitance, inductance, etc. This step is the basis for learning PLC, because the design and implementation of PLC control system is inseparable from the familiarity and mastery of electrical components. At the same time, learning PLC also requires mastering some basic computer and programming knowledge, such as binary numbers, logical operations, process control, etc. This knowledge can be learned through self-study or by taking relevant courses.
After mastering some basic knowledge, you can start to learn the specific instructions and programming methods of PLC. You can start with simple switching control, and gradually learn analog control, data processing, communication control, etc. In the learning process, you can combine the specific PLC model and experimental equipment for practical operation, and master the basic functions and applications of PLC by writing simple programs.
In addition to programming knowledge, learning PLC also requires an understanding of the overall architecture of industrial automation systems and related equipment, such as motors, sensors, actuators, etc. At the same time, it is also necessary to understand the design and implementation methods of some industrial control systems, such as the design of automated production lines, the optimization of control programs, etc. This knowledge can be accumulated through practical experience and continuous learning.
In conclusion, learning PLC requires mastering knowledge and skills in many aspects, and it needs to be studied and practiced systematically. In the learning process, you can combine practical operations with actual projects to deepen your understanding and mastery of knowledge through problem solving.
