3. Demand situation

PLC can control a variety of machinery or production processes to achieve the automation of the production process. PLC can perform logic, sequence, timing, counting and calculation and other functions, since 1969 the United States developed the world’s first programmable controller to the present, the PLC infrastructure has basically not changed, but the technology of various parts and components has been greatly improved, and the market and application fields have undergone great changes. Programmable controllers have always been recognized as one of the three pillars of modern industrial automation, with output, sales and consumption ranking first in various industrial control devices.
The current industrial automation technology has matured, and the future development direction is more intelligent. The reason why industrial computers are widely used in this industry is that it has the characteristics of fast data transmission speed, strong stability, dustproof, low radiation, anti-interference, electromagnetic compatibility, anti-perception and so on. The product quality of the industry is stable and reliable, and can be ALE111-S50 widely used in power automation, iron and steel metallurgy, petrochemical, mechanical and electrical complete sets of equipment, medicine and food, CNC machine tools, industrial furnaces and other industrial fields, as well as military, scientific research equipment and other harsh environment fields.

With the comprehensive digitalization and intelligent upgrading of the industrial manufacturing field, the application demand for cutting-edge technological achievements in the global manufacturing market has soared. Especially in recent years, the PLC (programmable logic controller), known as the “brain” of the industrial industry, has become more and more important in the field of ensuring the safety of the industrial control industry chain, and is of great significance for the development of industrial robots, intelligent manufacturing and other subdivision industry tracks.

Third, industry segmentation market analysis

ALE111-S50

1, small PLC

Depending on the number of I/O points, PLC can be divided into small PLC, medium-sized PLC and large PLC:

Small PLC: I/O node less than 256 points, small size, low price, mainly used for small equipment to achieve a single function;

Medium-sized PLC: The I/O node is between 256 points and 2048 points, and initially has the communication function and analog function, and has a relatively rich instruction system, which can be applied to large control systems or multi-machine systems;

ALE111-S50 Large PLC: PLC with I/O nodes higher than 2048 points is a large PLC, with superior performance in hardware and software, strong communication capabilities and processing capabilities, mainly used in large distributed control systems.

Small PLC downstream mainly for the OEM market. Small PLC is mainly used in the low-end OEM market, in recent years, the technical level of domestic brands has gradually improved, with high cost-effective and customized model development capabilities, to promote the market share of domestic brands into the accelerated growth period. After the outbreak of the epidemic in 2020, the demand for mask machines broke out, driving the rapid growth of small PLC demand, superimposed lack of foreign capital supply, domestic brands have obtained valuable import substitution opportunities, with high cost performance, rapid response, customized model development capabilities and good after-sales service advantages, small PLC localization rate continues to improve. Since May and June 2022, the supply shortage of foreign brands in the field of small PLC has eased, and the market share of domestic manufacturers has been affected to a certain extent, but by means of product performance and price advantages close to foreign investment, they have held most of the shares seized during the epidemic, and the localization rate has improved to a certain extent compared with that of 2021.
