Understanding Raspberry PI OPC UA Server
Posted: 19 Mar 2014, 18:41
Hello everybody,
I have recently received my CD of the Raspberry Pi OPC UA server based on the C OPC UA SDK.
Now I'm trying to figure out, how this software works. Later I'd like to add some new features to it:
To my understanding different "OPC UA projects" can be found in the include directory. I had a brief look on the code and could see that there were different directories regarding different projects, e.g. PiFace.
I took some time to make my way through the different files of this PiFace directory and could see that there was some code defining the different nodes, that are supposed to be visible in an OPC Client.
But i couldn't find any code that turns the led lights on and of , if e.g. an output node's state is set to true/false.
Where is this handled?
Would be really nice if somebody could help me understand how this server works.
Unfortunately i could't find any documentation regarding the Pi opc ua server.
