Hello,

I am trying to establish connection with OPC UA Client ( Siemens demo example for Tia Portal V15.1). OPC UA Server, I have locally on S7-1200 and Tia Portal V16 (FW v4.4). 

I succeed to connected to Server (s7-1200).  At first connect go opcuastatus go from 16#7001 to 16#7000. That i think is OK, but I get opcUaDiagnostic 16#8733 and subfunction status 16#8033_0000. When I try to read data, I get status 16#8604 and subfunction status 16#B080_3500. 

I was export data model from server (s7 1200) and import it to client( s7 1500 SIM Advance v3.0) and also with online browsing in Tia Portal v15.1 and the same with no success.

I am also looking traffic with wireshark. 

Any idea? What can I try?
