Hi Łukasz, Thanks for your reply.
It is Twincat 3 for me. I was able to get a connection for reading and browsing the PLC. One of my problems have been related in the load-symbol-and-data-type-tables option. I had set it to false. I thought the driver would discover the symbolic addresses on a per variable bases while querying it, but it doesn't. As soon as I set the options to true I can browse the variables.

For twincat 2.x you can use .<VAR_NAME> syntax, for 3.x you use <Task>.<VAR_NAME>. Given your example, for TC2 symbolic address on plc4x side will be .GVL and .GVL_TEST. For fresh twincats it will be Main.GVL and Main.GVL_Test (assuming you have such task in your PLC project).
