Where to start learning PLC

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....

Of course, the structure, the classification, the characteristics of the different models begin. The second is to learn some programming knowledge, start with basic and common instructions, slowly do some small control requirements of the program, learn to use programming software, and basically can operate. Later, I will learn communication and complex instructions, and some big projects will be higher.

Wang Yun, director of Jinan CNC Mold Science and Technology Research Institute, senior engineer, member of China CNC Machine Tool Association, senior expert of CNC machine tool maintenance national tour, consultant of Shandong University, Jinan University, Shandong Jiaotong University, consultant of Sinotruk Group, he opened CNC machine tool maintenance, PLC, inverter, touch screen and other related training.

First of all, ask you how good you are an electrician, and how good you are an electrician.

1.Develop a good interestSince you are not interested in PLC programming, how can you learn it well? Therefore, you can think of programming as a fun intellectual game, which will encourage you to have enough perseverance and perseverance to complete the programming.

2.PLC learning focuses on practice, and it is absolutely impossible to learn without practice. This is also the most important thing for learning PLC.

Therefore, it is necessary to have PLC and related hardware equipment as the object of practice when programming, so that the relationship between the program and the actual equipment action situation can also be intuitively reflected when the program is detected, so that the fault point can be easily found out when the equipment action is wrong, otherwise there is no control object, the fault point is difficult to analyze, and it is difficult to judge whether the program is correct or not.

3.Develop a good habit of programmingWhen writing a slightly more complex project, we need to analyze the process of the project--- that is, draw a flow chart When writing a program, the intermediate relay used must have a sequence and rules, otherwise it will be very disorderly in programming, and it will be troublesome in the future program modification. At the same time, in the process of writing the program, the role and intention of each step and each signal are marked, so that you know the intention of each step of your programming, and you can also see it at a glance when you review the program.

After having a certain foundation of electrical control, you can learn some basic knowledge of PLC, and then practice using PLC to do some simple logic control tasks, such as controlling the start, maintenance and stop circuit of a motor. After slowly getting to know PLC, I can further use PLC to do some late field tasks. The key is to design the circuit with a discreet logic.

Find out the relationship between i o. Wait for the logic control to be done well, and then learn the functional instructions of the PLC, and practice programming with functional instructions. As long as you take the time, PLC will definitely learn well.

During your studies, you can look for some reference programs, which can help you save a lot of things.

There are two channels for learning PLC, the first is a special training course, you can sign up for learning in a special professional training course, and the other is to buy relevant information for self-study, of course, now there are many types of PLC, and learning is only with Cong Chong to get started, if you want to be proficient, you have to exercise more in practice.

If you have your own computer, then I strongly recommend that you spend a thousand dollars and buy a PLC (Chun Rough Hidden S7-200, there are domestic ones. Of course, you can also choose others, such as Sanstool Keling, Delta, Haiwei, and Haiwei's programming is similar to Mitsubishi's).

Then make some switches, buttons, relays, contactors.

Find simple examples of your own and treat them as projects.

If you can make it, it's basically a beginner. Of course, you also need to learn electrical CAD, you must be able to draw, and you can take over projects in the future.

Now that PLC is being used more and more widely, the demand for such talents is also increasing. If you want to learn PLC, you can first find some Yinna materials and learn by yourself, so that it can be regarded as a beginner. Then, find a better professional school, Fengqing.

Relatively large brands, products are very good, trustworthy brands.

1. All PLC learning.

First of all, buy a book about PLC (it is recommended to buy a book of "Electrical Control and PLC Application Technology" to take a look, the first half of this book talks about some commonly used electrical components and basic circuits in the electric control cabinet, and the second half talks about the application of PLC. It should be suitable, you can go to the bookstore to see. ）

And then there's a PLC on hand

Then, based on the examples in the book, you can figure out a small project on your own to implement a feature.

Finally, practice brings true knowledge, do a PLC project independently, the project is completed, the PLC will be mastered, the Siemens 200 series of small PLC is very suitable for novices to learn, it is relatively easy to get started.

First of all, it is necessary to understand the knowledge of electricians, understand the control of electrical appliances, understand various actuators, and then understand the working mode of PLC, input and output circuits, and finally understand the corresponding process.

1, learn PLC first of all to choose a good learning of which manufacturer's PLC, the Japanese PLC internal software integration is high application simple early OMRON, Mitsubishi application more, now due to the first and international cooperation between the application of Siemens PLC, Rockwell a little more, (although it is said that a brand is profound, others will soon get started, but people's energy is limited, must be used in the most widely used, potential, development of a direction, However, for each brand of PLC have some understanding, including imported, domestic, these have a corresponding understanding, for the characteristics of each PLC, advantages and disadvantages, these have a better understanding, then will be a rare talent in the market in the future. ）

2. PLC is not a single programming technology, it is a system professional course. A PLC can be broadly considered a highly reliable PC with an operating system embedded in the back. First of all, you need to be proficient in the programming language ladder diagram and sentence table language of the PLC itself.

At this level, you can only read the programmed programs and design some of the programs needed for the project. In this industry, it is also necessary to apply VB and VC to realize serial port communication and distributed control system. Knowledge of databases is also required in some large programs.

PLC is quick to get started, but you have to keep making an effort. ）

3. PLC is a discipline that focuses on the application direction. So a little more practice. Don't look down on small projects, where you can summarize the logical thinking method for designing programs.

Keep making progress in the summary. For example, every time you go to the site to debug, call the program on the site to view, from which to understand the structure of the program, and other programs are different and characteristics, then the progress will be faster, good luck!

Understand the principle of PLC results, learn assembly language and instruction system, and slowly design some simple programs, and you are almost introductory.

Learn the electrical first, then look at the relevant PLC information, and take your time1
