PLC, also known as programmable controller, is the most important part of electrical control in automation control. It is now widely used in textiles, metallurgy, automobile production, food and beverage, electronics manufacturing, chemical industry, power plants, papermaking, oil mining and In the fields of mechanical design, national defense, etc., since I contacted and started learning PLC in 2002, I have been using PLC to develop, design and technologically innovate various automation equipment. After the second half of 2008, I am committed to integrating my learning experience and practical experience with PLC teaching. In combination, we hope to cultivate more highly skilled talents in plc programming. Some people want to learn PLC, but they don't know what good it will be for them after learning. I think that learning PLC well will have the following help to life and your knowledge structure. 1. It can improve the computer level. To learn PLC programming, you must first learn the installation and uninstallation of various PLC and touch screen software. Of course, typing is also an indispensable requirement. The application of the menu in the software is equivalent to learning the basic knowledge of computers. Some people use computers. You can only use the mouse to click, and over time, this is actually computer blind, and to learn PLC programming, the keyboard and mouse must be used in conjunction. In terms of computer hardware, the computer configuration requirements, serial port and external interface are naturally learned in the study. Second, naturally I also learned English well. The commands LD (load), OR, ANB (and block), SET, DMOV (double move) and English help files and English manuals in the PLC software make you have to remember these words and professional English. Third, it is equivalent to getting your knowledge of computer language and microcontroller programming language into the door. PLC mnemonics (instruction list). ST high-level programming language and touch screen macro instructions and D scripts are actually the prototypes of computer C language and single-chip assembly language. Many instruction codes have the same function and effect. They are used in PLC programming. The received binary, octal, decimal, hexadecimal and bit components, word components, arrays, bytes, 16-bit binary signed integers, 16-bit binary unsigned integers, 32-bit floating point numbers, etc. This is the international standard for computer languages exactly the same. 4. Learn electrical engineering knowledge and electronic technology. A large part of the people who are beginners to PLC programming have no electrical engineering foundation and do not understand electronic technology, but after slowly learning and applying, they have also learned the self-locking interlocking, self-holding, and electronic technology in the circuit. The AND gate, the NOR gate and the PWM circuit and the source drain in the PLC input circuit and so on. 5. Improve logical thinking ability. To write a complete electrical program for system mechanical equipment engineering, you must be aware of equipment actions and processes. In order to complete equipment functions, first select relevant electrical materials and relevant component models, draw circuit diagrams, wire and install, and perform Preliminary debugging, programming and improvement. After the performance objectives of the equipment are achieved, it is necessary to write operating instructions, organize and file data, etc., and at the same time, whether the logical relationship between the various variables applied in the programming is reasonable and whether there is any contradiction. Can provide the logical thinking ability of programming learners. Sixth, by analogy, the production technology of machinery, pneumatics, hydraulics, and various products will change from unfamiliar to familiar or even proficient over time. When dealing with equipment, it is indispensable to contact with these, such as dividers, manipulators, electric cylinders, solenoid valves, proportional valves, transmitters, hydraulic transmissions, etc., as well as the process flow of the equipment, and the guaranteed technical parameters. In order to understand, be aware of. Seven, exercised self-study ability. I often meet students or people who want to learn PLC programming and say, "I want to learn Omron PLC programming", "I want to learn Delta PLC programming", "I want school Panasonic PLC programming", "I want to learn servo" and so on. As soon as I heard it, I knew that they didn’t understand programming or hadn’t delved into the content of the course. Take most people who successfully learn programming as an example. Most of them started with a PLC from Mitsubishi or Siemens or Omron series. Then, after understanding the principle of one type of PLC, other types of PLC are basically the same. This is exactly the same as learning to drive. If you learn a kind of car, other cars will be able to think about it. For servo, many people understand it as the most technically new type of industrial control equipment. In fact, the servo is only slightly more complicated than the frequency converter, and the function is basically the same. It is an actuator with higher control accuracy than stepper motors and frequency converters. When we learn it, it is nothing more than adjusting the servo parameters and wiring like the inverter. It is much simpler than learning PLC programming well. To really learn programming well, in addition to having a good and experienced teacher to teach students how to understand the relevant knowledge in a simple way, it also requires more hands-on work and more practice to consolidate the learning content. At the same time, students also need to strengthen their self-learning ability. How to flexibly apply the content of learning to practice and work, which requires self-understanding. The above is a little experience as I have been engaged in PLC programming and related teaching for more than ten years, and I hope it will help me to become a PLC programming designer.
