Since the early 1980s, with the deepening of China’s reform and opening up, while the introduction of complete sets of equipment, foreign original programmable controllers began to flood into the domestic market. Many departments and units have successively introduced programmable controllers and designed their own control systems, and their application scope has also expanded to the industrial fields of building materials, light industry, coal, water treatment, food, pharmaceutical, paper, rubber and fine chemicals.

With the improvement of application capability and the expansion of market demand, some departments and units are carrying out secondary development and application research on the one hand, and on the other hand, introducing production lines of programmable controllers, establishing joint ventures to produce programmable controllers, and actively developing their own products based on the principle of combining technology with trade and digesting and transplanting.

At the same time, China also began to develop programmable controller products. At that time, more than 20 scientific research institutions, colleges and universities and factories in Shanghai, Beijing, Xi’an, Guangzhou, Changchun and other places were developing and producing programmable controllers. However, due to lack of funds and follow-up research force, and relatively backward production technology, they could only stay in the laboratory stage, and failed to put into practical application and form industrial production.
