In 1971, Japan introduced this new technology from the United States and soon developed Japan’s first programmable controller DSC-8. In 1973, Western European countries also developed their first programmable controller. Our country began to develop it in 1974 and began to apply it in industry in 1977. The early programmable controller was designed to replace the relay control circuit, store program instructions, and complete sequence control. Mainly used for: 1. logical operation 2 Timing, counting and other sequential control are all switch control. Therefore, it is usually called programmable logic controller (PLC). In the 1970s, with the development of microelectronics technology, PLC adopted a general-purpose microprocessor. This controller is no longer limited to the original logic operation, and its functions are continuously enhanced. Therefore, it should actually be called PC – programmable controller.

By the 1980s, with the development of microelectronics technology such as large-scale and ultra-large-scale integrated circuits, the microcomputer-based PC composed of 16-bit and 32-bit microprocessors has achieved amazing development. It has made a new breakthrough in the concept, design, performance, price and application of PC. Not only is the control function enhanced, power consumption and volume reduced, cost reduced, reliability improved, programming and fault detection more flexible and convenient, but also with the development of remote I/O and communication network, data processing and image display, PC has developed towards the direction of continuous production process control and become a major pillar of industrial production automation.
