Industry 4.0 Has Developed Rapidly, Driving the Surge of Market Demand for PLC

  • PostDate：2022-07-04


Programmable logic controller, referred to as PLC, it uses a kind of programmable memory, used for its internal storage procedures, the execution of logical operations, sequence control, timing, counting and arithmetic operations and other user-oriented instructions, and through digital or analog input/output control of various types of machinery or production process. PLC has microprocessor digital electronic equipment, used to automatically control digital logic controller, control commands can be stored in memory, ready to load and run. The PROGRAMMABLE controller consists of internal CPU, instruction and data memory, input and output unit, power supply module, digital module and other modules. The ESSENCE of PLC is a special computer for industrial control, its hardware structure is basically the same as a microcomputer, the basic composition is :CPU, I/O board, display panel, memory, power supply. 

PLC can usually be divided into nano, micron, medium and large four categories, of which medium PLC in the market share is the highest, in 2020 33.42%;  Nanoscale PLC accounted for the lowest proportion, 10.32%;  Micron and large PLC accounted for 27.99% and 27.27% respectively.  From the perspective of downstream application market, PLC applications are mainly concentrated in steel, petrochemical & natural gas, electric power and automobile and other fields. Among them, the application in the automotive field accounted for the highest proportion of 24.90%.



High regional concentration of the industry, the market is concentrated in North America and Europe 

From the regional point of view, Europe is the world\'s largest PLC industry revenue market, 2020 European PLC market size reached $1621.82 million, accounting for 40.67% of the global market share;  Second, the North American market with 34.89% of the second;  Japan was third with 14.48% of the market.  The market share of China and other regions is only 4.55% and 5.41% respectively. It can be seen that the regional concentration of the global PLC industry is very high, and the market is concentrated in North America and Europe. 



However, we predict that the share of North America and Europe will decline to 34.16% and 40.31% respectively by 2026.  Japan\'s market share will also decline, falling to 14.22%in 2026, down 0.26 percentage points from 2020.  China is expected to be the fastest growing market, with its share forecast to rise to 5.47%by 2026.

Industry 4.0 Has Developed Rapidly, Driving the Surge of Market Demand for PLC

The total market revenue of the global PLC industry in 2015 was $3,502.57 million, and then began to rise year by year, increasing to $3987.75 million in 2020.  Market revenue grew at a compound annual growth rate (CAGR) of 2.63% from 2015 to 2020. 

The main growth indicator for PLC in discrete manufacturing is the expansion of the deployment of automated robots in automotive manufacturing, electrical and electronics industries.  The market is expected to benefit greatly from the global robotics boom as robots become major end users of PLCS.  The markets studied are strongly influenced by industrial output and investment in computers and software.  These PLCS have traditionally been the foundation of process and discrete plant automation.  Adoption of Industry 4.0 is becoming more common across verticals, thus expanding the market under study.

It is estimated that due to the increased industrial investment in mining, oil and gas in the United States, which has a large share in North America, this promotes the use of PLCS and thus contributes to the growth of the market.  SCADA is widely used in the UPSTREAM, midstream and downstream sectors of the U.S. oil and gas industry.  In the upstream sector, its role is usually strictly defined as primarily supporting remote data transfer.  However, due to the wide use and diversification of SCADA, the demand for PLCS will effectively increase. 

Smart manufacturing initiatives such as the Smart Manufacturing Leadership Alliance (SMLC) also contribute to this advantage, facilitating the widespread adoption of manufacturing intelligence and automation technologies.  The next generation of urban infrastructure is on the horizon and with the development of Industry 4.0, Internet of Things technology is getting higher and higher, one can soon expect local authorities to rely on it to improve living, working and travel conditions.  The government will focus on developing smart cities, and the demand for industrial digital computers will be high in the coming years.  The establishment of the Advanced Manufacturing Partnership (AMP) is just such an initiative, enabling industry, universities and the federal government to invest in emerging technologies.  This factor has helped the country gain a competitive advantage in the global economy, and as automation increases, the demand for PLCS will grow in the future.  Overall, many factors will promote the rapid development of PLC market.  It is estimated that by 2026, the global PLC industry market income is expected to reach $4865.65 million.

However, for a long time, control system design only focuses on the realization of functions, lack of corresponding information security protection design, active control system exposed a large number of information security risks.  Once these hidden dangers are used, they will directly cause serious damage to the device, such as shutdown, failure mode, automatic restart, program crash, and data area damage.  "Bugs" in products cannot be fixed in a timely manner and rely on manufacturers to upgrade or issue patches.  Siemens PLC\'s multiple DoS high-risk vulnerabilities are still awaiting remedies from manufacturers.  For example, "Iraq nuclear accident" Siemens S7-400 PLC control system was "Stuxnet" virus attack vulnerability shocked the world, the product exists "back door" and other risks.  The current international mainstream PLC control system is easily affected by the global synchronous epidemic and rapid update of a variety of mutated viruses.  These factors will hamper market development to some extent.
