In the manufacturing industry characterized by changing geometric shape and mechanical properties, and in the process industry characterized by physical and chemical changes to transform raw materials into products, in addition to the feedback control based on continuous quantity, there are a large number of open-loop sequential control based on switching value in the manufacturing industry, which performs sequential action number according to logical conditions and acts in sequence; In addition, there is the control of interlocking protection action according to the logic relationship independent of sequence and time sequence; And a large number of state variables such as switching value, pulse value, timing, counter, analog quantity out-of-limit alarm and so on – discrete quantity data acquisition and monitoring. Due to these requirements of control and monitoring, PLC has developed into a product that mainly replaces relay circuit and carries out sequential control. Over the years of production practice, PLC, DCS and IPC have gradually formed a tripartite confrontation, and other single-loop intelligent regulators have accounted for a certain percentage in the market.

From the 1980s to the mid-1990s, PLC was the fastest growing period, with an annual growth rate of 30-40%. Due to the improvement of PLC’s processing simulation ability and network function, it has occupied a part of the DCS market (process control) and gradually monopolized the sewage treatment industry. However, due to the emergence of industrial PC (IPC), especially the development of field bus technology in recent years, IPC and FCS have also occupied a part of the PLC market, so the growth rate of PLC in recent years is generally slow. At present, more than 200 manufacturers in the world produce more than 300 kinds of PLC products, which are mainly used in automobile (23%), grain processing (16.4%), chemical/pharmaceutical (14.6%), metal/mining (11.5%), pulp/paper (11.3%) and other industries.
