I would like to know the advantages and disadvantages of Zhejiang University Zhongkong DCS
Thread Content
What are the advantages and disadvantages of Zhejiang University Zhongkong DCS in use? What is the communication status with other PLCs? What are the timing limits for signal transmission and logical operation execution between electrical components? What about the storage of history, events, and alarm data? Is the configuration intuitive and easy to understand? What are the requirements for system control points and capacity? Is it possible to make configuration changes online and offline? What are the main maintenance tasks for the system? Common faults………………? Everyone, please help me. I want to learn more about **, thank you! ! !
1. Advantages: It fits the habits of Chinese people – simple and easy to use； Two major domestic brands, with technical support available ； 2. Disadvantages: I don’t know what you’re worried about? It’s still within the country, and they are professional manufacturers; it’s recommended to listen to what their competitors have to say about the central control system. 3. Communication: Communication takes place via communication cards with the PLC, but there isn’t much information available regarding the configuration of this communication. If you decide to use it, ask the central control system provider to give you detailed explanations and provide relevant materials, so that you can practice on your own ； 4. Execution time: Personally, I think it is slower than PLC; whether it can meet the requirements is uncertain. Please set conditions and ask the control center to provide a technical solution ； 5. History, events, alarms, etc.: Quite good, very convenient, concise ； 6. Intuitive configuration: The configuration is in full Chinese, and explanations can be provided in Chinese during the configuration process; it is possible to ask those responsible for the configuration to write these explanations clearly so that even operators can understand them. If you are a maintenance technician, it is advisable not to make the configuration instructions too detailed, as overly clear markings might sometimes lead to misunderstandings ； 7. Number of control points, capacity: no problem ； 8. Making modifications to the configuration both online and offline is possible; the ECS-700 supports incremental updates, but it’s not clear whether other systems support this feature ； 9. Faults: Except for the ECS-700, the other models have a cage design; their biggest drawback is that mice are more likely to get inside the cage, leading to situations similar to \"The Great Sage Equal to Heaven has been here.\" ； I have been using it for over a decade, and I ran into some SP316 card components of the JX-300X model that were of poor quality ； During debugging, several components were damaged due to external factors; no other problems occurred. Satisfaction is the overall assessment of him ； 10. Configure and practice by yourself*: Set up the corresponding simulator, which makes things much easier

In my opinion, the disadvantages are as follows: The Zhejiang Zhongkong devices that are currently in use with ECS100 do not support external storage, and it seems the same is true for the JX-300. The ECS700 is unaware of this; the use of half-precision floating-point data in the control system is related to this storage capacity, and some of the operational functions are not very user-friendly
The advantage of a central control system is its simplicity and ease of use. The downside is that the project staff at the central control office are not very responsible
On-site personnel prefer central control for two main reasons: 1. Experience has shown that the system of central control is highly stable. 2. The configuration is simple and convenient, and easy to learn.
It’s just average; it seems to have better overall integration with Rolex, in terms of both technical support and hardware and software capabilities: lol
