Can anyone please advise me on what operations are supported by the Pi OPC HDA Server. I have read the pdf and it states the following :-


"The OPC HDA Server offers two types of operations to get data from PI System: Advise and Read."


It would be helpful to have details on the functions supported ReadRaw, ReadProcessed etc.
