Data Layer Question With OPC UA Client Apps

[soup01Threes]

Dear All Professional,

*My ctrlX Works is 1.20

Now i am testing with the OPC UA Client Apps.
the connection is fine and I can get the data from OPC UA Server.

But Now i would like to get these data from My PLC Runtime.
Although I Reflesh the Data layer many time, I still can not see the opc ua client Layer.
Would you give me some hints?

As the DataLayer_Realtime node in ctrlX PLC Engineering is only available for realtime data provided via the ctrlX Data Layer and the OPC UA client app is only providing non real time data it cannot be chosen there.

You will have to use CXA_DataLayer.DL_ReadNode function block to access the data. See more information and an example in the online documentation.
