Just a precision about the opc ua. I use codesys 3.5.8 and rapberry pi.
I test opc ua this day. Just a little program. No global var. Impossible to obtain access to locals variables with opc ua client. The tree of opc ua server -in the client - is small.
The solution requires to check globals variables to obtain the full tree in the opc ua client (UaExpert, OPC UA Dashboard for example ). It's now possible to display variables.
Great and I have also tested with the KEPServerEX UA Client, Work all great.
I do have a little question, if you have been able to have the Codesys Runtime to sllep for about 10 sec before startup, since the OPC UA Server /port needs do be delays at reboot/startup to have the OPC UA Server Work correct?
Look forward to receive your feedback.

Hi,
beside the recommendation of Peter with the 10s delay (this is still needed)
I would recommend to use Rasperry Pi Package 3.5.9.10 and CODESYS 3.5.9.10 Development System
There are many bugfixes and improvements according OPCUA.
so a sleep 10 or 20 should be added in
/etc/init.d/codesyscontrol
