N8812BTC

Computer control technology is an important branch of automation technology. Among them, computers are used to collect, control, process, store, and display various kinds of information. The application and development of computer control technology in various industries has greatly improved the automation, intellectualization and information level of production. The application field and working principle of N8812BTC controller are discussed in detail in this article.

N8812BTC is a computer-controlled universal process controller developed by EM company. This controller is widely used in control systems such as chemical, petroleum, metallurgy, environmental protection, textile, light industry, food, medicine, building materials, materials and so on. The N8812BTC controller has the characteristics of fast response, high precision, wide measurement range, large memory capacity and long maintenance cycle. Its main function is to realize real-time control of dynamic and discrete process variables, turbine speed, temperature control, and PID control.

In the implementation of the control process, the N8812BTC adopts the idea of function block pseudo-object programming to set the control parameters. This controller adopts P2 dual-channel communication mode. According to the P2 communication protocol standard, the functions of host, operator console, multiple data acquisition, high speed counter measurement, analog output, communication expansion and so on can be implemented.

In addition, the N8812BTC controller has the functions of Software Switch, auto-tuning software, manual tuning software, intranet communication software, debugging software, SCADA monitoring software and recording software. The above control and monitoring software offer basic parameters, instructions, circuits, measurement, linear and non-linear control logic and other powerful application functions.

The working principle of the N8812BTC controller is based on the P2 protocol communication system. Firstly, the process field software transmits the process data to the P2 socket, and then the P2 socket sends the data to the P2 bus. Then, the P2 bus sends the data to the host computer, which stores the data in the memory. Then, the control program will realize the output control based on the input state and process parameters. Finally, according to the set threshold values, the output signal will be sent out of the controller to realize the control task.

In a word, the N8812BTC controller is widely used in the field of computer control due to its wide application range, high precision and easy operation. This controller can realize remote monitoring of the application process, which enables it to implement process control in remote places, thus controlling and managing data uniformity and improving the safety and reliability of the process.
