PLC An industrial automatic control device, which takes a microprocessor as its core and integrates computer technology, communication technology and automatic control technology. PLC is widely used in industrial control industries such as automation and machine tools. However, PLC is expensive and unaffordable for many enterprises. The high cost makes it difficult to promote the development of automated production and informatization. Therefore, it is very important to develop PLC industrial control boards for automation equipment suitable for domestic enterprises. important.
PLC is widely used in transportation, chemical industry, electric power, energy, environmental protection, machinery manufacturing and other fields. It has high reliability, strong anti-interference ability, simple design, convenient maintenance, small size, low energy consumption and complete functions. It is an ideal industrial control system. core controller.
Muwo Technology believes that the importance of PLC in industrial control is reflected in the following points:
1, PLC can carry out simple and complex logic control, and has powerful logic operation functions;
2, equipped with A/D module and D/A Module, after conversion between the two, can control the analog quantity;
3, equipped with PID control module, can control temperature, flow, pressure, etc., mainly used in chemical industry, metallurgy and other fields. During the control process, if there is a deviation, the PLC can calculate the correct output through the PID module to control and adjust the production process;
4, with timing and counting functions, provides users with timers and counters , which users can set by themselves. Fixed time and count value;
5, can perform data calculation, transmission, comparison, conversion, display and communication, etc., and has powerful data processing capabilities.
6, install the motion control module, which can be used for motion control. Almost all PLC products have this function and are mainly used in machinery, machine tools and other fields.
7, the communication function is perfect. With the development of factory automation network, PLC manufacturers have begun to pay attention to the communication function of PLC, which communicates between PLCs and with other intelligent devices.
With the development of computer networks, PLC, as an important part of automation control, will play an increasing role in the field of industrial control. In order to meet the needs of industrial control, richer and smarter products will appear in the future. The computing speed will become faster and faster, the storage capacity will also increase, and the development of PLC industrial control boards will become the development direction and focus of enterprises.
