The working principle of industrial computer and PLC

The working principle of industrial computers is similar to that of ordinary computers, which are composed of standard operating systems such as CPU, memory, and hard disk. Windows or Linux, industrial computers have powerful processing capabilities and flexible software programming capabilities, and can run various industrial control software and data analysis tools. In contrast, PLC is a hardware device specifically designed for work control systems, typically composed of processors, input/output module memory, etc., and runs a specially designed real-time operating system; The design of PLC mainly focuses on stability, real-time performance and reliability, and quick response to input signals; The PLC programming method usually uses logic graphic programming language, which provides a more intuitive control logic through ladder diagrams.
