Development of plc in 1969, dec developed the first plc in the world according to the requirements of gm (general motors company of america) and successfully applied it in gm company. After that, the company commercialized plc. Plc is specially designed to compete with relay products and gradually replace the traditional relay. Plc, as a special industrial computer, has experienced the following development processes.

1969-1972 is the first stage of PLC, which is the initial stage of PLC. In this stage, the PLCs of various manufacturers are very different, there is no unified hardware and software standard, the function is simple, and the specificity is strong. The hardware is mainly separated components, and the volume is large, the performance is poor, and the reliability is not high.

1972 – is the second stage, in which plc gradually evolved into a special industrial computer, with greatly improved reliability and greatly reduced cost, the appearance of process-oriented ladder diagram and statement table language, and the gradual transition of the system to standardization, all of which laid the foundation for the popularization of plc.

From 1981 to now, iec has officially published the standard of plc, and the plc of all manufacturers are developing towards standardization. Ladder diagram, statement table and sfc language have matured, and there is also interface with advanced programming language. Its storage capacity, operation speed, and processing function of analog quantity have been greatly enhanced. Now large and medium-sized plc has the classical pid algorithm, slope function, adaptive algorithm, fuzzy control and other algorithms that were “unique” to dcs.
