Hello, I have an issue with the OPC-UA client.  
I've configured an OPC-Server in SILMENS PLC S1500 and added an OPC connection to Ignition.  
When I open the quick client, I can read all tags configured as DataBlocksGlobal, all inputs etc., but I can't see any tags configured at DataBlocksInstance. When I try to open the folder it seems to be empty. In order to eliminate any configuration issues in Siemens, I've connected to it using a different OPC client and I saw the DataBlock instances.  
Maybe someone encountered the same issue?  
Would appreciate help on that.

A support ticket has been made for this. Solution is to address the OPC tag manually in the Designer through the OPC Item path.
