Hongde is the first choice for PLC training, one-on-one teaching package

The road to development is long and arduous. It has been many years since the Ningbo Hongde Technical Research and Training Center was established, and the market potential is still huge. In my country, the proportion of supporting mechatronics products is increasing year by year, while the proportion of users using conventional relays and other control products is gradually shrinking. Among the development trends of , the most eye-catching is networking and intelligence, including the introduction of bus technologies such as Ethernet, and the introduction of technologies such as fuzzy control machine vision, which greatly enriches the scope of applications and improves living space. In this issue, we will interview Mr. Ying Rongliang, deputy manager of Hollysys’ wind power project department, to discuss the development trends and application status.
originally appeared to complete the control strategy, in order to replace relays and enable users to complete control system ladder diagrams similar to relay circuits. Therefore, most of them use ladder diagrams for programming. However, with the complexity of mechatronics products gradually Improvement, when many ladder diagrams cannot complete the final programming work correctly, other programming languages will slowly be favored by the public. What do you think of ladder programming versus other programming methods?
Most of Ying Rongliang's current industries are still in traditional logic control situations, and ladder diagrams still have great advantages in such applications, being intuitive and simple. At present, the ladder diagram language is still the programming language with the largest number of users and the most widely used industry. However, with the improvement of control requirements, the functions and application scope of the device are gradually expanding, the data processing capabilities are becoming more and more powerful, there are more and more analog applications, the logic control is becoming more and more complex, the number of points is increasing, and the programming Increasingly, in this application, not only traditional languages such as ladder diagrams are required, but also structured text languages and sequential function diagram languages similar to high-level languages. The language is similar to a high-level computer language and supports statements such as judgment loops, which has great advantages when dealing with some complex calculations and algorithms. The language is a sequential function chart, which can be controlled sequentially according to the process. It is more suitable for process control fields with a large number of points and standardized steps. Language and language are important supplements to the ladder diagram language and an indispensable part of future programming languages.
In 1998, General Motors of the United States put forward a requirement to replace relay control devices. The next year, American Digital Corporation developed the first programmable controller, which met the requirements of the company's assembly line. With the development of integrated circuit technology and computer technology, there are now fifth-generation products. What do you think is its current development trend? What new products will your company launch?
Ying Rongliang currently has the following development trends
Functions are becoming more and more subdivided. There are more and more individual needs in the industry, especially in the small field. One product is often targeted at some industry applications, and the situation of one product conquering the world will basically never happen again.
The boundaries between large and small are becoming increasingly blurred. With the development of computer technology, the data processing capabilities and communication capabilities of small-scale computers have been greatly enhanced. In point-to-point applications, many small-scale computers can also meet the requirements.
The requirements for network communication functions are getting higher and higher. On the one hand, the requirements for networking and integration require more and more people to be connected to the computer monitoring network as a node of the network. On the other hand, smart instruments are used more and more widely, so they require more fieldbus interfaces to communicate directly with smart instruments.
User experience requirements are getting higher and higher. Due to the popularity of computers, more users have begun to accept some operating habits of computers, which has put forward higher requirements, especially in programming. Users require a user-friendly interface, convenient and flexible operation, the upper and lower level can share the same database, and the programming is simple and easy to learn, etc.
In response to the above trends, Hollysys has conducted sufficient market research and technology development, and is about to launch a series of products on the market for the machinery and equipment supporting industry, with capabilities such as communication functions, motion control capabilities, etc., which are greatly improved compared to previous products. promote.
We have formulated a programming language standard based on , which should be said to be an international standard. What do you think of this standard? Do your company's products implement this standard?
The introduction of Ying Rongliang has standardized the standards of programming software and unified user usage specifications, so that users no longer need to invest a lot of time in learning software programming when using software from different manufacturers. The promotion of this pair has great benefits.
Since the first version of HollySys, its programming software has always followed software standards. In the future, we will still develop according to this standard to provide users with better products.
Some people say that the upward connection of the network is an Internet problem, and the downward connection is a fieldbus problem. What do you think of the network and bus problems?
One of Ying Rongliang’s development trends is networking. On the one hand, the requirements for networking and integration require more and more computers to be connected to the computer monitoring network. As a node of the network, Ethernet communication capabilities are required. On the other hand, smart instruments are used more and more widely, so they require more fieldbus interfaces to communicate directly with smart instruments.
