The simulation program is running, but the OPC connection keeps being denied access. DCOM was also configured; the OPC client tool can locate the local OPC server, but a connection cannot be established, with an error indicating that group addition failed. But the OPC client tool can connect to other OPC servers on the local network, which indicates that the DCOM settings are fine and the LH2411 authorization is in place; I need experts to help

Permission issue; change OPC configuration to classic mode
