I am trying to connect our product to PI over Express Interface (Xi). When PI is the server, I can simply wrap the OPC servers with the Xi wrapper that's supplied from the Xi site. (http://expressinterface.com/) However, I have not figured out a good way to use Xi when Pi is an OPC client. There is no off the shelf client wrapper that I can find. Has anyone done this and know a good solution?
Also, are there any plans for PI to support Xi natively? I found a reference that OSIsoft was one of the developers of the Xi standard. (http://www.emersonprocessxperts.com/mt/mt-search.cgi?blog_id=2&tag=Express%20Interface&limit=500)
Thanks for any ideas or solutions,
