How can we add a server to read OPC data from Zhejiang University’s central control system?
Thread Content
Now, it is necessary to use OPC to read data. The OPC authorizations are separate and not combined; therefore, it is not possible to have two authorizations on the same server. An additional server must be used to read the OPC data. How can this be achieved? How should this server be configured? Please provide some guidance
Help push it a bit; I want to know too.
Reading OPC data from outside the system does not require authorization; secondary calculations must be used. . . Mine is a JX 300XP; I’m not sure what system you use. In the future, please describe your questions clearly; otherwise, how can I answer them? . :(
The system is JX-300XP; it needs to read data from Zhejiang University’s control system. Without proper authorization, only 10 pieces of data can be read. In other words, a separate server is required for handling OPC communications with Zhejiang University’s control system. How should this server be configured? If it lacks operator authorization, will it shut down every two hours? Will this affect the OPC data reading?
My understanding is that you want to add a central control OPC server so that third parties can read the data from the central control system through this server, right? In that case, a single OPC license is completely sufficient, as the OPC server can run independently without the monitoring interface; just one additional computer is needed.
The Central Control JX 300XP usually comes with an engineer station license for configuration downloading; another type of engineer station comes equipped with an OPC SERVER license. This authorization allows the data from this site to be provided to other systems (including the central control system) via OPC communication. Reading data from the OPC servers of other systems, including those in the central control system, does not require any authorization; this is achieved through secondary calculations using OPC drivers, with the points being displayed on the screen. A network card needs to be added to each operation station. These points are used solely for display purposes… This can be tried out by oneself. No downloading is required – only publishing is needed.
What I mean now is the former type – the one that requires authorization. However, the engineer doesn’t have OPC; there is a separate OPC authorization token
You can contact the control center to have the OPC authorization entered under the operator settings! ! !
Additionally, if only a portion of the data is to be transferred to another system (with no data written to the DCS and where stability requirements are not particularly high), we can use the approach we currently employ (without dogs or OPC)
