[Opcxml-users] OPC and the Open-Source

[Victor R. <vr...@ce...>]

Hello All

I've been studying the OPC and I'd like to take part on the development =
of a "cheap" solution for data acquisition in small industries and in =
the academic environment (laboratories, for example).

I've noticed the rise of XML as interfacing technology and now I would =
like to port some OPC solutions to open-source. My first try would be a =
OPC-DA server for Modbus, running on top of Linux, but I still have some =
doubts with the middleware. What is a good way of running DCOM on Linux? =
Is .NET really free, so that I can use C# for the solution? The second =
part my intended solution is an XML-based PHP server for posting data to =
the WEB.

All kind of information would be greatly appreciated. Thanks for your =
support! :-)
