Which one is the best in DCS?

Which one is the best, and which one is the worst?
In the field of DCS (distributed control systems), which one is the best usually depends on specific application requirements and personal preferences. Well-known DCS suppliers include Siemens, Emerson, and Honeywell, among others. As for which one is the worst, it depends on the specific usage conditions and user experience; generally, it is recommended to choose a suitable DCS system based on actual needs and system compatibility. .
Usually ABB, Zhejiang University Zhongkong, Siemens, etc. . . . .
Domestic DCS systems are led by Zhejiang University Zhongkong and HollySys; among them, HollySys’ DCS systems have been used in several nuclear power projects in China. Foreign brands include Honeywell, Emerson, Yokogawa Electric, ABB, etc. There is no such thing as the best one; only what suits you
Siemens’ PCS7 is too complicated to understand, and there is little documentation available, making it difficult to learn. In our factory, we use Zhejiang University’s Zhongkong system; as we were among the first users, we were given a significant discount.
More or less the same; it’s just a matter of seeing which one offers the best value for you
Honeywell and Yokogawa have mature control technologies in large-scale industries; the capabilities of the other companies, including those in China, are also good
What kind of high-profile expert can answer your question?
I agree with your point. PCS7 was introduced only after 2010; essentially, it is a configuration software developed based on Siemens’ high-end PLCs. The system is quite complex, and its logical structure is rather convoluted, making it unfriendly to end-users. It’s difficult for them to fully understand how it works.
