01Global PLC market analysis: Siemens leads, the rise of domestic forces

In the wave of modern industrial revolution, the programmable logic controller (PLC) as the industrial control brain, with its excellent control and monitoring capabilities, accurate control of a variety of complex machines and equipment, has become a key role in the automation process.

PW441-10  In the global PLC market, giants such as Siemens, Mitsubishi Electric, Omron, Schneider and ABB have long dominated. In 2023, Siemens holds the top spot with a market share of up to 40%, followed by Rockwell, Omron, Mitsubishi Electric and other manufacturers, see the chart below for details:

Although the share of domestic manufacturers in the PLC market in 2023 is only 15%, China’s PLC market space and growth rate are faster than the global market. Data show that in 2022, the global PLC market is 13 billion US dollars, is expected to reach 15.79 billion US dollars by 2027, the compound annual growth rate of 4.56%, and in 2023, China’s PLC market is expected to reach 16.54 billion yuan, this data not only reveals the future of China’s PLC market growth potential, It also indicates that China’s PLC market is about to enter a stage of rapid development.
