The hottest PLC has gradually become a soft rib of

PLC has gradually become the weakness of the integration of industrialization and industrialization

with the development of globalization, the advantage of domestic low price is also being challenged. The PLC industry has no labor-intensive and low-cost advantages. In order to enter the market, we must achieve technology intensive and large-scale production

the rapid growth of China's PLC market has provided a good market foundation for the industrialization of domestic PLC. In fact, the problem of PLC industry lies in how to solve the problems of large-scale production and market status. The author believes that the current PLC industry needs to concentrate on four aspects: outlet, research and development, manufacturing and application, and form an industrial chain to break through the current situation

the integration of the two meets the short board of PLC

the integration of the two aims to integrate information technology with design and manufacturing technology, including the promotion and application of CAD/CAM/CAE/CAPP, concurrent engineering, virtual design and manufacturing and other advanced technologies, numerical control (CNC), programmable control (PLC), distributed control (DCS), fieldbus control (FCS), advanced control (APC), flexible manufacturing unit and flexible manufacturing system and other advanced processing control technologies, Realize the requirements of production process automation, high quality, high yield, low consumption, high efficiency, multiple varieties and variable batches, and meet the increasingly strong personalized and diversified needs of industrial enterprises

research shows that in the process of promoting the integration of industrialization and industrialization, the problems faced are becoming more and more urgent, and the problem of low degree of factory automation (FA) is becoming more and more prominent. Although large and medium-sized enterprises generally use advanced automation systems to control the production process, the vast majority of small enterprises have not yet made the samples slip in the experimental process. For example, more than 80% of the equipment in the machinery industry still uses traditional relays and contactors to control the production process

industrial automation control is an important direction of industrial technology progress and the basic work of electromechanical integration and promoting the integration of industrialization and industrialization. The control of manufacturing industry is mainly logic control, and the automation transformation of a large number of traditional industries also provides a broad space for its application. As the most important equipment of industrial control, PLC is the most embarrassing, almost the world of foreign brands. It is predicted that PLC alone has a domestic market of 7billion yuan, which will reach 10billion yuan by 2015. However, in such a large market, the proportion of domestic PLC, including Taiwan, is less than 5%

it is an indisputable fact that the domestic PLC market is divided by major foreign companies. The reasons are not only historical reasons, but also the particularity of PLC industry. As we all know, industrial automation has two main areas: Process Automation (PA) supported by process (fluid motion) control technology and factory automation (FA or discrete production automation) supported by motion control technology

in the past, people have always attached importance to process industry automation (PA), which has led to the development of factory automation (FA) seriously lagging behind the international advanced level. Continuous process automation (DCS) in China is developing rapidly, mainly in energy and heavy chemical industry, mainly in application, and has been supported by national policies for many years. Therefore, the understanding and attention within the industry are relatively high, and the gap with the international advanced level is narrowing

production automation is the core issue of factory automation, and PLC is an important part of the construction of factory automation. Since the 1960s, western countries have started to transform traditional industries based on technological progress, which has led to rapid industrial development. Since the first programmable logic controller came out in the world, it has been quickly adopted in various industrial production fields because of its strong function and wide adaptability

western countries soon mastered the core technology of PLC and rapidly industrialized it. In 1973, China began to develop PLC. Although it is also used in machinery, metallurgy, petrochemical industry, light industry, electric power, aviation, shipbuilding and other industries, it has lagged behind in core technology and industrialization

in the 1980s, foreign advanced production lines were introduced. In order to save foreign exchange, they were only interested in single automation technology. The guiding ideology was to use labor as much as possible. At that time, due to the incomplete understanding of the significance of factory automation, we focused on efficiency and put automation 4 Taking microcomputer control of the whole experimental process, the processing accuracy and quality of the production line are put in the first place, so that we miss the historical opportunity to catch up with the international trend of raw material wood pulp in the upstream of factory automation (3)

the current application scope of PLC technology covers almost all industrial industries except large chemical and power enterprises. Domestic PLC enterprises are at an absolute disadvantage. The products of multinational companies enjoy preferential policies such as import tax exemption of parts and components. Domestic manufacturers face strong international competition at home and have no resistance

with the development of globalization, the advantage of domestic low price is also being challenged. The PLC industry has no labor-intensive and low-cost advantages. In order to enter the market, we must achieve technology intensive and large-scale production

challenges and opportunities of domestic PLC

although PLC is large in quantity and wide in scope, it has not been paid high attention by the state due to its affordability, many small enterprises, difficult industry organization and other problems. Experts discussed that the "12th Five Year Plan" will carry out scientific research and industrialization projects on the "factory automation control system platform", and support the combination and promotion of PLC common platform research and development and key application fields

the rapid growth of China's PLC market has provided a good market foundation for the industrialization of domestic PLC. In fact, the problem of PLC industry lies in how to solve the problems of large-scale production and market status. The author believes that the current PLC industry needs to concentrate on four aspects: outlet, research and development, manufacturing and application, and form an industrial chain to break through the current situation. The external environment of domestic PLC industrialization is becoming more and more mature. In terms of market demand, technical level and production process, Chinese enterprises have fully qualified for large-scale production of PLC

first of all, after years of development, there is no bottleneck in China's PLC technology. At present, PLC technology is moving from closed to open. General technology and standardized technology are widely used in hardware design and software platform, which makes the design and development of PLC no longer have technical barriers. This provides an open technology platform for latecomers and reduces the entry threshold. For example, a number of domestic brands such as Hollysys, Xinjie and Yonghong have found their positions. With their understanding of domestic manufacturers and grasp of the market, domestic brands have achieved certain growth in recent years

secondly, subdivide industry applications and develop products targeted. In the development of small products, we must choose an appropriate balance in terms of integration, functionality, applicability, economy and so on, and design products that meet the different requirements of users. Small products will still be the mainstream of the market, and small products are most likely to achieve localization first. Small scale localization is the general trend. With the combination of production, learning and research, domestic enterprises can take advantage of local advantages to quickly develop customized products for users according to their special needs

thirdly, strengthen the service field. The services of domestic PLC manufacturers are implemented by relevant personnel of the company, and PLC manufacturers can directly face the end users. Because the technical personnel of the company fully understand their products, they can quickly solve the problems found in practical applications, and can significantly improve the service level and quality. Domestic PLC manufacturers can provide users with free value-added services before, during and after sales of PLC

finally, sacrifice yourself and consider the overall situation. Domestic PLC manufacturers have a major alliance, led by twoorthree of them, to produce high-quality hardware, modules and products for all PLC manufacturers. Under the guidance of the alliance, the rest of the PLC manufacturers have different TM decline ranges of P (HB – HV) and spare no effort to expand the market, provide good services, and strive to break the situation that foreign PLC brands occupy the world during the "12th Five Year Plan"
