HDA data collecting from ABB.AfwOPCDaSurrogate or ABB.AfwOPCDaServer?
I'd like to save data with MatrikonDesktopHistorian. On the 'OPC-server' called \\FIELDSTATION there are two different server, ABB.AfwOPCDaSurrogate and ABB.AfwOPCDaServer, available.
What is the difference between them?
Which one is best choice?
