Compared with major international companies, the disadvantages of domestic PLC manufacturers:
Brand disadvantage
In the initial stage of market development, the brand of domestic PLC was not recognized by users for a long time, which increased the difficulty of market development.
Application performance disadvantage
Compared with the internationally renowned PLC manufacturers, domestic companies have less PLC application performance, and users are skeptical about the performance, product quality and technical support of domestic PLCs.
Product line disadvantage
In the first few years of the domestic company's PLC business, the PLC product line is not perfect, and the variety of products is less, which is not conducive to all-round market development.
R & D strength disadvantage
Compared with the famous PLC manufacturers with strong strength, the R&D strength of domestic companies is weak.
While waking up to the competitive disadvantages of domestic PLC manufacturers, people are also happy to see that domestic companies have a greater competitive advantage in the development of PLC business.
Demand advantage
Domestic PLC manufacturers can accurately understand the needs of Chinese users, and timely develop and produce marketable PLC products according to the requirements of Chinese users. For example, Hollysys has 12 years of experience in production, sales and engineering implementation of control products, and has accumulated a large number of customer resources to understand the real needs of different industries, different regions and different ownership systems in the country, so it can be fully considered in product design. The needs and usage habits of Chinese users are more targeted and easy to use.
Product customization advantage
Due to the completely localized research and development, production, sales and technical support, domestic PLC manufacturers can customize personalized products according to the special needs of users. In actual work, some users want to have functions such as digital input, digital output, analog input and analog output on one PLC module. At the same time, the output must have both relay and transistor. This kind of general PLC can not provide special requirements, domestic PLC manufacturers can quickly customize for users. It is difficult for Chinese users and Chinese employees of multinational companies to quickly feedback this special demand directly to foreign manufacturers, which makes it difficult to improve the product.
Cost advantage
Due to the completely localized R&D, production, sales and technical support, domestic PLC manufacturers have a large cost advantage, and this cost advantage directly translates into product price advantage.
service advantage
The services of domestic PLC manufacturers are implemented by relevant personnel of the company, and PLC manufacturers can directly target end users. Because the company's technical staff fully understand their products, they can quickly solve the problems found in practical applications, thus significantly improving service levels and service quality. In addition, domestic PLC manufacturers can provide users with free value-added services before, during and after the sale of PLC. For example, in the face of numerous small and medium-sized users, Xinjie Company has launched free training and free program design services, which have won unanimous praise from users.
Response speed advantage
Compared with international PLC manufacturers, domestic PLC manufacturers can respond to user requirements more quickly.
Domestic plc brand rankingAs the core of the control system, PLC plays a vital role. If the PLC is selected correctly, the choice of other components makes sense. At present, the domestic manufacturing industry is in a period of reform and transformation, which is a good time for the development of domestic PLC. The following is the list of the 8 most powerful PLC brands in China (in no particular order).
1, Yonghong PLC
Yonghong PLC is the PLC product of Yonghong Motor Co., Ltd., and Yonghong Motor Co., Ltd. was founded in Taiwan in 1992 by a group of engineers who have been engaged in PLC design and development for many years. Yonghong focuses on the high-performance small and medium-sized PLC market, and its own brand “FATEK†has enjoyed a high reputation in the industry.
In recent years, in the face of competition from many large manufacturers and changes in client applications, only providing PLC products can no longer meet market demand. On the other hand, Yonghong has occupied a considerable economic scale in the market of micro PLCs. It is no easy task to grow up. Therefore, in addition to PLC products, providing more complete industrial automation solutions is a problem that Yonghong needs to face today. At present, the specific development direction is still to develop a higher-performance PLC to stabilize the core competitiveness. At the same time, it is more active in motion controllers, human-machine interfaces, industrial power supplies, servo controllers, inverters and servo motors.
2, Delta PLC
Mr. Zheng Chonghua, the chairman of the godfather of Taiwan's electronics industry, founded Delta Electronics in 1972 and started his entrepreneurial journey with 15 people in order to open up the Japanese to build their own national brands. . When the small Delta Electronics was hard-pressed, it stood out from the fierce competition and emerged in the industry. Delta Group not only "winned" Japanese manufacturers, but also defeated European and American manufacturers, becoming the world's number one power supply manufacturer, the world's largest component manufacturer, and the world's largest supplier of peripheral products for the computer industry, with 30 per year. The speed from % to 40% continues to grow.
Delta PLC Delta Group is an electronic device specially designed for industrial automation and digital computing operation. Delta PLC uses a program-programmable memory to store instructions for performing operations such as logic operations, sequential operations, timing, counting, and arithmetic operations, and can control various inputs through digital or analog inputs and outputs. Type of mechanical or production process.
Delta PLC is known for its high speed, robustness and high reliability, and is widely used in various industrial automation machines. In addition to features such as fast execution of program calculations, rich instruction set, multi-expansion function card and high cost performance, Delta PLC supports a variety of communication protocols, making the industrial automation system integrated into one.
Delta's full range of hardware devices can form a control system that can meet various requirements. Users do not have to design and manufacture hardware devices themselves. After the hardware is determined, the user does not have to change the hard device of the PLC in the case of production process change or production equipment update, and only needs to adapt the program to meet the requirements. Therefore, in addition to being applied to stand-alone control, PLC is also widely used in factory automation.
3, Hollysys PLC
