PLC, namely programmable logic controller, is a computer control system specially used for industrial automation control. It has the characteristics of strong real-time, strong anti-interference ability, high reliability and good stability. PLC is usually used to control industrial production lines, robots, assembly lines and other automation equipment.
Single chip microcomputer is an embedded computer system, which integrates the functions of processor, memory and input/output interface on one chip. It has the characteristics of small volume, low power consumption, low cost and high reliability. Microcontrollers are usually used in embedded systems, smart homes, smart toys, medical equipment and other fields.
PC is a general computer system, which consists of CPU, memory, hard disk, graphics card and sound card. It has the characteristics of strong universality, good expansibility and superior performance. PC is usually used in office, entertainment, design, programming and other fields.
To sum up, PLC, MCU and PC have different characteristics and application scenarios, so it is very important to choose the appropriate computer system according to actual needs.
