PLCs (Programmable Logic Controllers) and Industrial Panel Computers are two types of devices in the field of industrial automation, and they play an important role in controlling and monitoring industrial processes.
1. Definition: PLC is a device specially used to control the automation process. It realizes logic control function through programming and is usually used to realize discrete control. The industrial all-in-one computer is a comprehensive device that integrates functions such as a computer, a touch screen, an operation interface, and some I/O interfaces. It can run software applications for controlling and monitoring automation processes.
2. Function: PLC mainly exchanges data with external sensors and actuators through input and output modules, collects input signals, performs control operations, and gives corresponding output signals. Its programming language is usually based on logic and bit manipulation, such as remote control, signal passing, and state transition, etc. As an integrated device, the industrial all-in-one computer can run various applications, in addition to the control function of PLC, including data processing, man-machine interface, and data storage.
3. Relationship: The industrial all-in-one computer can integrate the control function of PLC, that is, install the PLC operating environment on the industrial all-in-one computer to realize the logic control function of PLC. Such a device has both the multimedia processing capability of the industrial panel computer and the real-time control capability of the PLC. The industrial all-in-one computer can also be used to monitor and configure the PLC. Through the touch screen and man-machine interface on the industrial all-in-one computer, users can easily view and modify the parameters and status of the PLC.
Overall, PLCs and industrial panel PCs are closely related devices that are often used together in industrial automation applications. PLC is responsible for real-time control and logic operation, while industrial all-in-one computer provides more functions, including man-machine interface, data processing, and storage, etc. By combining them together, a more complex and comprehensive industrial automation control system can be realized.
