As per this link:
Siemens - Ignition User Manual 8.1 - Ignition Documentation (inductiveautomation.com), we can take only absolute address of Siemens PLC during OPC tag creation in the Designer, so instead of this Absolute address, can we take symbolic Address ? if yes how ?
No, you can connect to S7-1500 enabling OPC-UA server of plc, and than read tags via OPC-UA ignition as a client.

I'm wondering the same thing. Is this something that will be addressed in v8.3? Have you found any answers?
