Today we had a little internal brainstorm session about adding OPC UA to the list of supported interfaces for openSCADA. While openSCADA implements the OPC DA client side using native Java it of course be nice to have something similar for OPC UA.
But since OPC UA is not based on COM/DCOM it would interesting to not only have a client side but also be able to export openSCADA functionality using OPC UA on the server side. Imagine having an open source OPC UA implementation which exports the OSGi based „master“ server providing direct access.
Since openSCADA already has the idea of multiple wire protocols (ICE from ZeroC was implemented in the past) it should no be big issue writing another „Exporter“ which simply exports a „Hive“ implementation using OPC UA. Of course the same would be possible not only for DA, but for AE and HD as well.
But for now this is only a bit of brainstorming …
