Was there DCS in the 90s?

Same question: were DCS systems used in domestic chemical and petrochemical plants in the 1990s?
Some:lol:lol:lol:lol:lol
In the 1990s, DCS systems were used in domestic chemical and petrochemical plants, all of which were imported; at that time, companies like Zhejiang University Control System and Hollyland did not yet exist.
It has been around for a long time. There are over 10,000 points in the petrochemical industry – how can humans keep track of all of them?
I’m not aware of anything else; Sinopec Maoming Ethylene plant was completed in 1997 and uses Honeywell TDC3000. However, the first DCS manufacturer to enter China was Foxboro; it seems that the Shanghai Chlor-Alkali Plant had a set of DCS systems installed there in the late 1980s.
Yes, we have used the Foxboro IA series here
Let’s talk about the practical situation: our factory first started using touchscreens in 1996. Before that, only two or three workshops had DCS systems, while our factory has more than a dozen workshops. In 1998, the first DCS used in our workshop was one that had been upgraded and phased out from another workshop.

At that time, the control and display instruments were of the panel type, but the start-up and shutdown processes were carried out using the DCS. In 1998, the JX-300 system from Zhejiang University Zhongkong was introduced for the monitoring of the central height room.
In the 1990s, Daqing Petrochemical Company gradually replaced type three instruments with DCS.
The three large ethylene plants introduced in the late 1980s used Honeywell’s TDC-2000
