Hi everyone, I am trying to read some Historical Data from an OPC UA Server into WinCC 7.4 SP1 but with no success. The document titled OPC Unified Architecture by Siemens suggests that I need to install the "OPC Historical Data Access - Write Access" option which I assume is part of the WinCC ConnectivityPack. But this does not serve my purposes since then I have what is essentially two OPC UA Servers: on one side lies the OPC UA Server with the Historical Data I want to bring in WinCC and on the other side lies the WinCC OPC UA Server. Could these two Servers be connected somehow? If not, can WinCC OPC UA Client read Historical Data? And if that is also not possible what are my options for reading Historical Data from an OPC UA Server? Thank you for taking the time to read this. Best regards, Filippos |
