Is there a good guide anywhere to help administrators used to the tradition PI Interface way of doing things to transition to using PI Connectors? Some colleagues have installed the OPC-UA connector and created a hierarchy. They were surprised that this created Base class tags instead of Classic ones. I assume the tag is linked to the source tag through its element name and location in the AF hierarchy directly mapping to the same location in OPC-UA and that things like scan rate etc are defined within OPC-UA? It would be good if someone could point us at a document/web-page comparing and contrasting interfaces and PI Connectors and detailing how the configuration process has changed. I have had a bit of a search and can't find anything suitable.
