Abstract: Driven by the development of modern science and technology, industrial technology is gradually developing towards the direction of modernization, automation and intelligence. In the use of industrial automation technology for production, the most important link is to do a good job of automatic control. Now this paper on the industrial automation control related research and discussion.

Key words: Industrial automation; Control technique

3BSE018741R15 In the electrical industry, electrical engineering and automation belong to a new discipline, which has a direct relationship with industrial production, and also has a close relationship with people’s life. It is because of this characteristic that it has been developed rapidly, but also makes this discipline develop more and more mature. With the continuous development of electrical automation control technology, electrical engineering and automation has gradually become the most key part of the high-tech industry, and is also widely used in every industry field of our country, which provides strong technology guarantee for the economic development of our country.

1. Development status of industrial automation control

3BSE018741R15 At present, the technology of industrial automation control has been greatly developed in our country, and gradually the automation control system tends to perfect. But in spite of this, industrial automation control technology still has a great development and application space. At present, the more commonly used automation control products are mainly PLC and industrial control PC two kinds, the application of these two kinds of automation control products represent the level of industrial automation control in our country has a great development.

1. Development and application of l PLC

PLC is the English abbreviation of programmable controller, is by the United States General Motors in 1968 first proposed the related idea of programmable controller, and in the next year developed the world’s first PLC. Subsequently, all countries in the world began to actively develop PLC, which greatly promoted the rapid development of PLC. Until today, PLC has become a widely used industrial automation production control equipment, in the development of industrial automation plays a great role in promoting.

3BSE018741R15 In fact, PLC has always been a pioneer in the development of industrial automation, but also the development focus of industrial automation. This is because the use of PLC in industrial production is very wide, not only can realize the automatic control system of single machine automatic control, but also can be used in the production equipment on the assembly line. It can not only perform logical operations, but also realize timing, counting and control production sequence through program Settings. And because it is controlled by the plug-in module structure, it can be directly counted
