The development of PLC controller
In the 1960s, computer technology began to be applied to industrial control. It was the predecessor of PLC controller. However, due to the complexity of computer technology itself, the difficulty of programming, the difficulty of adapting to harsh industrial environments and the high price, it has not been widely used in industrial control. At that time, the industrial control did not require a PLC controller, and the main control system was a relay-contactor.
In 1968, General Motors Manufacturing Corporation (GM), the largest automaker in the United States, tried to find a new type of industrial controller (also known as the current plc controller) to minimize the need to adapt to the refurbishment of the car model.
In 1969, the United States Digital Equipment Corporation (GEC) first developed the first PLC controller and successfully tested it on GM's automated assembly line, thus creating a new situation in industrial control.
Then, the United States MODICON company also developed the PLC controller 084. In 1971, Japan introduced this new technology from the United States, and soon developed the first PLC controller DSC-8 local. In 1973, Western European countries also developed Out of their first PLC controller. China began to develop in 1974 and began industrial applications in 1977.
In the 1980s, with the development of microelectronics technologies such as large-scale and ultra-large-scale integrated circuits, microcomputer-based PCs composed of 16-bit and 32-bit microprocessors were strikingly developed. The PLC controller has made new breakthroughs in concept, design, performance, price and application. Not only control functions are enhanced, power consumption and volume are reduced, cost is reduced, reliability is improved, programming and fault detection are more flexible and convenient, and with the development of remote I/O and communication networks, data processing and image display, the PLC controller has been developed in the direction of continuous production process control and has become a pillar of industrial automation.
