I develop in both C# and Java and am looking for resources that will help me properly access PLC manufacturing data (OPC data) so I can collect large amounts of data. I plan to research data patterns in order perform predictive analysis. I can handle everything on the client side..... the server side is kicking my butt. The OPC foundation limits all of their content to their members, as a student becoming a member isn't an option. If anyone can point me in the right direction to somewhere other than google, stack overflow or wikipedia, I would be very appreciative. I have loved learning some of the basics, but after 25+ hours searching the internet I need someone to point me in the right direction.
