Some beginners have spent a lot of time in theory. As a result, they still didn't understand plc in half a year. In fact, they just lacked some practical experience of PLC. Just do some actual ladder diagram writing, program downloading, debugging, etc. Increase the perceptual knowledge of PLC, and you will soon be able to master the PLC technology. At the beginning, you can learn a brand of PLC first, because all PLC principles are similar. You can master a PLC and just use the manual to get started.

You can edit some simple ladder diagrams at the beginning of the course, such as the AND, OR, and output of the contacts, and run them in the PLC machine. Success will increase your interest and confidence in learning. Then use the main functions of the PLC one by one, such as high-speed counter, you can use the pulse output end of the PLC itself to connect to the input of the high-speed counter, download the programmed ladder diagram, open the variable observation window, run the program, observe the count Is the value correct? After such practice, you basically know what PLC can do, and you can be confident in the actual industrial control application.

The self-learning PLC method is as follows:

a. Using instructional videos, it is best to follow the teaching video system scientifically, and cover the three major plc learning videos and trials. Interested beginners can get a solid foundation here.

b. About the practice 0 yuan rental machine is a good choice, PLC technology is a very practical technology, if you want to learn, then you must practice it. Programming is like a martial arts person. If you just sit at home and watch boxing all day, and don't go out to practice martial arts, then it is a powerful martial arts intensive, and his skill will not improve in a long time. Learning PLC is the same reason. It is useless to read a book. You can't use it after reading a PLC book for ten times. You can learn programming (no matter what language).

In the process of learning the knowledge of PLC books, you will definitely not know a lot of instructions. If you don't solve them one by one, then this will be the biggest obstacle for you to learn PLC. Therefore, the actual application, one by one, so that your PLC knowledge will not only learn well, but also in the process of learning you have mastered the actual use.

c. Design programming, after learning the PLC has a certain foundation, you can independently write a program of your own design, and then transfer it to the PLC to run the program. After repeated modification, debugging, and finally running successfully, your interest will increase greatly and achieve satisfactory results.

d. Data download, can be downloaded to PLC, inverter, Siemens, Omron, touch screen, Mitsubishi and other industrial control data and industrial control software.
