1) Network OPC DA: DataHub makes an OPC DA connection, and mirrors the data across the network. This eliminates all DCOM hassles and shields the OPC server and client from network irregularities and breaks. The OPC server and client never lose their connectons, just the data quality changes to "Disconnected". Once the network is restored the data set is immediately synchronized. 2) Multiple tunnels can be configured to aggregate remote Data. Connect your IT department to your OT data, securely. Configure redundant networking.
