How do you learn PLC? Rush 5

PLC training can go to program-controlled automationPLC training, please look for program-controlled automation! Professional, standardized, systematic training to help you become a PLC expert in 60 days! Program-controlled automation is an automation company that undertakes electrical automation program design, electrical and non-standard mechanical design, equipment transformation, and PLC training.

PLC training implements one-to-one on-the-go training, according to each person's progress in a single class, the next class starts from the last progress, so as to ensure the continuity of the course, not because there is no time to fall behind the course, and the learning time also ensures flexibility. People who are receptive can be faster. If the foundation is poor, it can also be longer.

Except for the Spring Festival, it is almost open all year round, which fully satisfies the students to learn at any time. Therefore, in program-controlled training, everyone is under their own control of the completion time. There is no time limit until the real learning is reached....

Start by learning the manual, then get hands-on. You can start with a few small experiments.

It is recommended to buy a PLC, buy a textbook, and look at the book to do experiments. Of course, if you are in the factory, it would be best if you could subscribe for it.

First of all, PLC learns a brand, and the rest is easy to learn, for example, we learn Siemens' S7200 series.

Second, the basis of PLC is mainly some industrial control knowledge, before learning PLC, we should learn electrical control technology and other related contactors, control methods and logical ideas, so as to lay the foundation for the application of PLC control.

Third, it is better to have a book to learn what to do, it is too messy to find on the Internet, there is no clue, most PLC books will start from scratch, a little introduction, in-depth, more suitable.

Fourth, in the initial study, we must pay attention to the most fundamental foundation, such as the composition of PLC, each memory type, and the working principle. On this basis, one by one, deeper and more complex instructions penetrate.

Finally, I wish you a happy learning, focus on persistence, don't know how to look more, ask more, the effect is better.

First of all, the second problem is that there are certain differences in PLC between various brands, even if there are certain differences in PLC of different models of the same brand. If you want to learn PLC, you don't need to learn all brands. Learn a brand of PLC well, and the rest is just different instructions and some differences in usage habits.

It's okay to use and learn.

The PLCs used by various enterprises in various regions of our country are different, but there is a strange phenomenon, which is relatively regional. You can check what brand of PLC most companies in your area use for self-study.

The question of self-taught PLC is more complicated. It depends on how far you want to learn PLC. If you're interested in digital circuits at the university level, self-learning PLC shouldn't be a problem.

You can buy any book, PLC belongs to one law, ten thousand laws. Mitsubishi's ** has PLC programming software, and after the program is compiled, the computer can be simulated without connecting to the PLC. Therefore, it is recommended that you learn Mitsubishi's PLC first, and because Mitsubishi PLC's main direction is small and medium-sized.

The degree of automation of enterprises in China is not very high, so there are not many applications for large-scale PLCs. There are a lot of self-study books of Mitsubishi's PLC in the bookstore, so you can buy a copy and read it. Focus on the example analysis part, after understanding the basic working principle and some simple logic control instructions, you can learn some functional instructions.

If you want to know more about the rest of the advanced instructions, I am afraid you need to refer to the manuals of various PLCs. Here's a list of the order in which you need to learn.

1. Basic instructions: the so-called normally open, normally closed, rising edge, falling edge (use these instructions to control the basic control of the motor, forward and reverse rotation, interlocking, sequence control, logic control, etc.).

2. Timer counter application: **Disk counting, traffic light control, material transfer, etc.).

3. Step instruction (simple manipulator action process traffic light control).

4. Shift left and move right instructions This kind of instruction is widely used and has some basic requirements for digital circuits, so do what you can (marquee control, etc.).

After learning the above instructions, go back and take a good look at the introduction of the working principle of PLC, it can be said that you have a preliminary introduction to PLC.

If you have studied MCU, it is simpler for you to learn PLC, and the programming language of PLC uses a ladder diagram that is easy to learn. When it comes to high-level programming, some programming ideas involve assembly and C programming ideas. If you have studied single-chip microcomputer and are familiar with the peripheral circuit of single-chip microcomputer, you can understand the peripheral circuit of PLC well.

I think the specific learning method is to first go online and get a PLC introductory tutorial, and then look at the manufacturer's instruction manual. The most important thing is practice.

Learn what brand you use in the place of work, there are a lot of introductory books, you can find two books on the Internet to see, and it is best to have a master to take you. After you have a certain understanding, then go to the big bookstore by yourself, take a look, and buy a fine book according to your own situation.

It's best to practice while learning.

Mitsubishi and Siemens had to learn that it was better to buy one yourself. Just learn about other brands.

Now the most commonly used is Siemens S7-300 400, you can learn about the information first, after understanding the working principle of PLC, other brands are easy to get started, and then just contact a few more projects.

If you have PLC equipment around you, you can learn from this type of PLC (or choose one of them);

It also depends on how your foundation and requirements are, whether you have electrical foundation, computer programming knowledge, just to do an understanding or preliminary application, or as one of the main technologies.

I'm looking at Delta's small PLC (ES2 operation manual) right now, and I can read through the basic instructions.
