What are the options and differences for common DCS software used in the chemical industry?

Experienced with HONEYWELL TPS; have used PKS, CS3000, and Zhejiang University’s JX-300X. Questions: 1. Among the control systems mentioned above, which one has the best stability? Yokogawa CS3000R3? The control systems of the companies mentioned above are all considered mainstream in the current market; their stability is fairly good, and none of them is the best. 2. Which system best fits the way of thinking of Chinese people? Including daily maintenance, configuration, and operation, I think they are pretty similar; once you get used to them, they are quite useful. 3. Which applications are most widely used? Please discuss them separately in the fields of petrochemicals, chemicals, boilers, and coal chemicals. In the petrochemical industry, HONEYWELL and Yokogawa are the most commonly used brands; especially in the past, HONEYWELL dominated this sector almost entirely. If you talk to former engineers from HONEYWELL, you’ll find that they almost all have experience working in petrochemical plants. There are many small systems from Zhejiang University and Hollyland; just take a look at their performance records to see – they are all related to boilers, air separation units, small petrochemical facilities, or thermal backup power plants in petrochemical plants. 4. In comparison, what are the respective advantages and disadvantages? Data storage, configuration, compatibility and communication with other systems such as the HIMA system? I haven’t studied it in depth, but it seems that previous engineering projects provided good support for third-party systems. There is actually also an issue related to the use of inertia; since the system is most familiar with that approach, it will naturally lean towards using that system. The previous supervisors in charge of the instruments all came from the Yokogawa system; they found Honeywell’s system unsatisfactory in every way, haha. . . . . . Personally, if you have enough money, go with Honeywell or Yokogawa (I’ve seen a fuel depot using the CS3000); if budget is a concern, choose Zhejiang University or LS. Personal opinion, for reference only.

It’s hard to say for sure if it will be stable. What people in their own country do generally fits better with their local habits. For applications, look at market share. Pros and cons: the range is wide; foreign options are comprehensive, and domestic ones can keep up as well. Data isn’t a big issue for hardware devices. Configuration is more complicated abroad, but it offers more powerful functions; simpler versions cannot achieve as much. Compatibility and communication are not a big issue now

For large systems, foreign brands such as Yokogawa, Honeywell, and Emerson DELTAV are used, while for smaller systems, Zhejiang University and HollySys are sufficient. It is said that Yokogawa fits the way of thinking of Asians, and Zhejiang University imitates Yokogawa. Actually, once you get used to using *, any brand is the same; saying that one brand is better is just a preconceived mindset:D

For domestic systems, Zhejiang University Zhongkong and HollySys are available; for imported systems, Yokogawa, Emerson, Honeywell, and ABB are all suitable options. Choose between domestic or imported products based on the device’s requirements; the specific brand is usually a good choice depending on *customary practices
