I would like to ask the plc industry how to do it, and what is the prospect! What company can I go to! Zero foundation! thank you

The PLC industry, to be precise, should be called the electrical automation industry, because we can't just learn PLC, but also learn touch screen, servo, frequency converter and other related knowledge. PLC is not a separate thing, it needs to be used with other components.

Electrical automation industry is a very popular industry at present, because with the continuous improvement of labor costs, enterprises are increasingly inclined to replace labor with equipment. Because the efficiency of equipment far exceeds that of manpower, and there is no need to pay insurance, pay wages and be emotional. So now more and more industries are doing automation equipment, so this major is very easy to find a job, as long as you can bear hardships. The current employment prospects are optimistic. With the development of artificial intelligence, robots have gradually replaced humans in repetitive work. But creative work still needs people to do, and automation industry is a creative industry. As long as you are creative and don't want to do some repetitive and mindless work all day, this industry is the best.

First, I will give you a few employment directions: power plants, power grids, power supply companies, power construction units, and electrical commissioning companies (companies that do automation engineering for heavy industries such as power plants, self-owned power plants, and chemical enterprises). ), power system equipment supporting enterprises, various electrical appliances (note that it is not "gas") manufacturing enterprises, electric power design institutes, industrial enterprises, automation equipment (such as packaging machines, filling machines, centrifuges), large automation companies (mostly foreign companies such as Siemens, Mitsubishi, Schneider and Rockwell). ), automation system integrators (large and small engineering projects), automation product manufacturers, electronics industry, information industry, automobile industry, metallurgy industry, construction industry, property management, artificial intelligence, industrial robots, sensor detection industry, power electronics, power supply. .........................................................

Third, but I must remind you again: this is an engineering major, and it will have a vital impact on your career development and income if college students start internship. This is a major that can't lie or brag. You may or may not, you may or may not. Basically you can see it by opening your mouth! Of course, if you are engaged in marketing, sales and other work, then you still need to "speak eloquently" and "properly brag". After all, "the smell of wine is not afraid of the depth of the alley." Only you have it these days, and there are fewer and fewer things that others don't have. The market has always been a "buyer's market". So you often have to take the initiative.

Fourth, summary.

No matter how good the major is, it doesn't matter whether it is good or not! Because what you have learned is nothing. If you can't help the wall with mud and sand, your opportunities will only be wasted and eventually eliminated.

How to get started quickly with zero-based learning PLC;

If it is zero-based, it may take a long learning time and a lot of patience.

1, it is recommended to learn the basic knowledge of electrical components, such as the types of PLC, the concept of touch screen, man-machine interface, etc. Switches, relays, contactors, thermal relays, electromagnetic valves, etc. Have a basic understanding of the basic components used in this industry.

2. It is suggested to buy a PLC basic course first, or buy some zero-based training and video courses. Basic programming and basic control can be realized through the guidance of video tutorials and the theoretical basis study of paper textbooks. You should learn to fully and flexibly apply basic instructions such as step logic control, the use of timer counter, pulse and position reset, and complete the test of whether you have mastered the most basic PLC use method through the experiments that come with the textbook. This step is the most basic, you need to understand and master the working principle of PLC.

3. Understand some common concepts of PLC, such as what is switching value, what is analog value, what is high-speed input and output, and what is communication? What are the significance of RS-232, RS-485 and CAN in communication, and how do they communicate? What is the scanning period? What effect does the scanning cycle have on the program? What is an interrupt? What are the benefits of using interrupts? Wait, wait, wait, wait, wait, wait, wait, wait.

4, the best learning is practice, if you have the opportunity to do a project, you do it boldly, don't be afraid of failure, or even dare to take failure, then you still don't learn PLC, because failures in PLC design are common, and you need to overcome them again and again. If you don't have a chance to do a project for the time being, I suggest you buy a PLC and electrical components first and give yourself a project to realize.

5. It's easy to start. If you arrive at the meeting place, you will have a long way to go. The meeting at this stage can't be achieved by reading tutorials and textbooks, but the guidance of tutorials is still necessary. In addition, you need to learn by doing through the project. You never know what you can't do, and you don't know that the original PLC control system is not only PLC, but also needs to master communication technology, low-voltage distribution knowledge, instruments and sensors. Master knowledge of motor drive, master knowledge of upper computer interface design, master knowledge of electrical design, etc. You may need a long time to accumulate knowledge. You can never stop learning PLC, and the product software is always updated. You should also keep in touch with new products, learn new ideas and keep learning. It is something that industrial control technicians must do. I wish you an early success!
