Secondary calculation of central control DCS
Thread Content
I have two computers on site, each connected to a different control cabinet. One of these computers needs certain data from the other; I want to handle this through secondary calculations. Both computers have OPC services enabled and are connected to the same switch. How can I achieve this?
What you’re saying is too general; the software configuration for the central control host should be described in detail. One of them needs several pieces of data from the other. All you need is one machine with an OPC server, and another as an OPC client to read data from the server. Then, calculations are performed via scripts on the host machine.
Both are equipped with servers to transmit data to the monitoring room; software version 300 2.7
1. Ensure that both systems have the necessary licenses for OPC server and client; otherwise, data cannot be retrieved even if the configuration is done correctly. 2. Make sure that the username/passwords for both systems are identical, and verify that the DCOM configurations are correct. 3. For everything else, follow the OPC-related configuration instructions provided in the software’s online help step by step. The last section provides a step-by-step introduction to actual projects.
