Hello everyone

Does anyone of You, dear users, create communication betweeen OPC UA Client Driver and S7-1500 built in OPC UA server?
I have created connection, OPC UA Client Driver is starting to import variables from PLC, but always finish with errors. 
Does exist manual for OPC UA Client Driver, where can I check syntax of variables. Is it possible to explore variables in PLC and choose only one variable? I don,t want to import all unneccesary variables. 

Regards Slawek
