S7-300 send data to PC with Ignition/OPC-UA

hi,I’ve another question regarding this topic :
is it possible to directly access the PLC symbols from the Ignition opc-ua server without using OPC client and SQLTags ?

I mean, I’d like to develop an OPC-UA client that directly accesses the datapoints in the same manner as described in Siemens Drivers addressing page (inductiveautomation.com/support/ … ssing2.htm )
thank you for your help
