Industrial control computer (IPC) is a computer specially designed for industrial control, with high performance, high reliability, high anti-interference and other characteristics. PLC (Programmable Logic Controller) is a controller based on digital operation, which is widely used in the field of industrial automation. Industrial computer control PLC can achieve more flexible and efficient industrial control.
The implementation of IPC control PLC
1.Control through communication protocol: The industrial computer and PLC can be connected through serial port, Ethernet and other communication methods, and use the corresponding communication protocol for data transmission and control. Among them, the modbus protocol is a widely used communication protocol, which can realize data exchange and control between industrial computers and PLCs.
2.Indirect control: The industrial computer indirectly controls the PLC according to the preset control logic by reading the status of the input and output modules of the PLC. This method requires the use of PLC programming software to write the control logic program and execute it into the PLC.
3.Direct control: The industrial computer is directly connected to the PLC through high-speed interfaces such as PCI and PCI-E, which can achieve high-speed data transmission and control. This method requires the use of specialized direct control software for programming and control.
Advantages of IPC control PLC
1.High reliability: The industrial computer adopts high-performance hardware and software, which has extremely high reliability and stability, which can effectively avoid hardware failures and software vulnerabilities in traditional control systems.
2.Flexibility: IPC can run a variety of operating systems, which can be customized and expanded according to different needs. As a programmable controller, PLC can realize a variety of complex control logic by writing programs, so as to meet the needs of different industrial controls.
3.High efficiency: The combination of industrial computer and PLC can achieve faster and more accurate data processing and control, thereby improving production efficiency and quality.
4.Easy maintenance: The failure rate of industrial computers and PLCs is low, and fault diagnosis and troubleshooting can be carried out through display lights and fault **, which is convenient for maintenance personnel to quickly locate and repair problems.
The application field of industrial computer control PLC
1.Power industry: In the power industry, industrial computer control PLC can realize remote monitoring and control of power equipment, and improve the stability and reliability of the power system.
