Automation control area optimistic about the PLC

In the field of industrial automation control, PLC's status is second to none. Even if the financial crisis hits, the market size will shrink slightly in 2009, but its development momentum is still strong. Even if the crisis is in danger, many PLC manufacturers are still optimistic about PLC's development prospects and continue to increase investment. In May 2009, Honeywell, the traditional process control company, also introduced the first PLC, the Master Logic controller, to China's discrete industry market and announced its formal competition with the PLC market. According to forecast, China's PLC market can recover to a high growth rate of 9%-11% from 2010 to 2012.

PLC can laugh at the automation market for more than 40 years and is inseparable from many of its features:
● The real-time performance of the process;
● Read and write the real-time nature of input/output (I/O) values;
● Guaranteed robustness and reliability of execution and continued operation;
● protect control code and execution from external influences;
● Independent functions ensure the specificity of control response.

Not only that, PLC technology and its products are constantly adapting itself to the needs of development, absorbing new technical content, transforming itself from multiple aspects of system architecture, control tasks, and software requirements for control requirements to adapt to the development trend and gradually penetrate into it. Discrete control, process control and hybrid control.

In the industry application, metallurgy, automotive, power industry, chemical industry and OEM provide PLC with a huge market and space. With the rapid development of new energy, the market demand driven by low carbon will also drive the strong growth of PLC. For example, although ABB introduced PLCs later than traditional Siemens, Mitsubishi and Omron PLC suppliers and Schneider and LG latecomers are late, but more concerned about the new energy market, wind power, solar power, biomass power generation and other fields The rapid development brings a huge space for ABB's PLC market.

The emergence and development of PC, DCS, and PAC have had a certain impact and impact on PLC, but it is still impossible to replace who in a short time, because there is still a large market for simple logic and sequential control. And PLC itself has been advancing. The current PLC has been very different from that of ten years ago. High-end PLC is more complete and powerful in function. It can be said that it is comparable to PAC, PC, and DCS also have their own areas of expertise. Currently, various technologies are In the application field, peace and competition are most likely to get along.
