PLC tags in the address space of the OPC UA server
The figure below shows where the PLC tags in the example are located in the address space
of the OPC UA server (excerpt from UA client):
The "MyDB" data block is a global data block. The data block is therefore located below the
node "DataBlocksGlobal". "StartTimer" is a memory tag and is therefore stored below the
"Memory" node.
