Currently, once PI tags are created by the PI Connector for OPC UA the connector uses the point ID for its mapping from the OPC UA server to the PI tags. Thus, if a configuration change occurs on your OPC UA server (i.e. NodeIDs change) the only way to map the newly named (with no change in the data stream) NodeID to a PI tag is to create a new PI tag instead of simply changing the configuration on a PI tag. As a PI system administrator, I want the ability to change a PI tag attribute (i.e. Extended Descriptor) and have the Connector automatically update which data stream is written to that PI tag.
