I recently learned about the Zhejiang University Zhongkong ECS-700. There is an existing project that involves configuration in the operation domain, including operation nodes and servers. Operation nodes can be understood as operation stations, but the concept of servers is a bit unclear. What’s the difference between configuring servers? How do they need to be configured? Is it necessary to install anything? It’s quite confusing
Remember that the control program is installed on the control station, and for the human-machine interaction interface, it’s sufficient to issue commands from the upper-level computer
So what’s the use of creating a new server?
A server is an IT device that provides computing power and runs application software within a specific network or area. The configuration server has stopped working, so configuration is no longer possible. There are also batch servers, clock servers, and historical trend servers; shutting down the corresponding functions will cause them to stop as well. For changes to the configuration program in the central control system that do not involve modifications to the display screens or module connections, it is sufficient to download the updated version; an operation station has been designed for such purposes.
There is none in Workshop 700; I have only used Workshop 300. In Workshop 700, multiple engineer stations can be available, and each engineer station can be configured. The configuration files are likely saved on some designated configuration server. For servers, it is to provide specific services, such as the clock and historical trends mentioned above. The server is responsible for exchanging data with the control station; as a result, the operator stations do not need to exchange data directly with the control station – they can communicate with the server instead. Otherwise, if there are 30 operator stations, the control station would be overworked. Now, the control station only needs to exchange data with a few servers, while the operator station can communicate with those same servers. The algorithm needs to be downloaded to the control station; if only the control algorithm is to be changed, a download is sufficient. If only the interface is changed, there is no need to download any algorithms; it’s sufficient to simply publish it. By \"publishing,\" it means that the engineer station compiles the graphical interface and transfers it in file form to both the operator station and the engineer station. Once the graphical interface is changed, the monitoring program restarts and runs with the new interface.

The main function of the data server is to receive and process real-time data and alarm data, to handle alarms on a global scale, to store alarm history records and operation history records, to save operational domain variables, and to provide real-time and historical data to other operation nodes.
700 is much simpler than 300; just set up the time server and the historical trend server
