Hello All
I've been researching methods to allow better data manipulation of tag data without resorting to clunky IEC61131 code.
With this, I believe the answer is to expose the tag data to the OS hosting the runtime.
I know that Beckhoff are using Codesys and have a library that can expose runtime tag data to a .NET application running on the host OS.

Can this be done with a base CODESYS installation running on a Linux OS (Raspberry Pi)?

Hi,
Raspberry Pi has an embedded OPCUA Server,
so I would suggest to use a OPCUA Client on your .NET application.

Thanks for the response @Edwin But this wont work if I want to share data on an application or service on the Pi?
Would I really have to go out and back through the ethernet port again just to get data?
What if I wanted a Java program - would I have to program a native bridge in C++?

Hi,
Sure this will work on the same Pi.
No data will be send over the network if you are using the local connection... localhost.
