The development of programmable controllers in China is different from that in the world. In the world, the development of programmable controllers is from research, development, production to application, while in China, it is from the introduction of complete sets of equipment, the introduction and application of programmable controllers, digestion and transplantation, joint venture production to extensive application. It can be roughly divided into the following three stages:

The primary understanding stage of programmable controller (late 1970s to early 1980s)

The development of programmable controllers in the world has first aroused great interest in the domestic engineering and technical circles. Therefore, China’s understanding of programmable controllers began in the introduction of complete sets of equipment from the late 1970s to the early 1980s. At that time, more than a dozen models of about 200 programmable controllers were introduced in many projects of Shanghai Baosteel Phase I Project. These programmable controllers are used in the whole steel smelting and processing production line from raw material wharf to blast furnace, steel rolling and steel pipe, replacing the traditional relay logic system, and partially replacing analog control and small DDC system. After Baosteel Phase I project, many domestic manufacturers have introduced equipment and production lines that are mostly equipped with programmable controllers, which are applied in power stations, petrochemical industry, automobile manufacturing, ports and docks and other fields. It is in the process of introducing complete sets of equipment that we have opened our eyes and learned about programmable controllers, which has also promoted the development of programmable controllers in China.
