External data access via OPC UA

Forums:

While these Raspberry PI's are quite handy, there are limited ways to get the sensor data off of them ind in to a a Microsoft windows invironment

I propose adding OPC UA support which is designed to be a cross platform communication protocol - more and more commonly used in industrial control applications.

Here's a link to an open source OPC UA
http://open62541.org/

Here are the directions I used to install it on my raspberry pi

sudo git clone git://github.com/open62541/open62541
sudo apt-get install git build-essential gcc pkg-config cmake python python-lxml

# enable additional features
sudo apt-get install libexpat1-dev # for XML-encodingi
sudo apt-get install liburcu-dev # for multithreading
sudo apt-get install check # for unit tests
sudo apt-get install graphviz doxygen # for documentation generation

sudo cd open62541
sudo mkdir build
sudo cd build
sudo cmake ..
sudo make

# select additional features
sudo ccmake .. # enter g to build and exit
sudo make

It seems to be added, now I need to know how to configure it
Sorry but I'm not a programmer, if any of you programmers out there could take a look at this and let me know if this tutorial looks reasonable to try

I want to figure out how to map the temps/pressures/weight etc that HiveTool collects to the OPC server, but I think baby steps can help me get there bit by bit.
