Connection between Siemens HMI and ctrlX Core via OPC UA

Hello Comunnity,

here is an onfield commissioning issue about the connection between a Siemens HMI (client) with our ctrlX Core (server) via OPC UA.

For engineering we are using 1.12 version for ctrlX Core Apps and ctrlX Works, while using TIA V16 and WinCC RT Professional V16.0.0 for Siemens component. 

In short word, the OPC UA connection was built up successfully but the variables in HMI were not working properly. 

For details plz. refer to the attached slides. Also the OPC UA certificate from Siemens is attched. 

We have tried several combinations of configuration in the client but none were useful. Please help us to find out the solution.

Thanks and best regards,

Hui
