Hello everyone,

this is my first post.I have a problem with the OPC UA interface. I am trying to modify our OPC UA interface according to our cross-company specifications. The structure is already predefined.  I am using SiOME Version 2.8.0 to model and build this structure and I could successfully map the variables.

However, I have the following problem: After compiling and loading the program onto the CPU, the declared variables are displayed as NodeID 5 instead of NodeID 2 when I view them via UAExpert. In addition, three additional OPC Server interfaces are automatically generated, even though the standard SIMATIC Server interface was deactivated at point OPC UA.  I would appreciate it if someone could tell me how to change the NodeID for the declared OPC UA variables.

Thank you for your support.

Hello Kjab86

Check in the Server-> NamespaceArray (while browsing the Server interfaces) Here you should get an overview which Namespaces are predefined and used in the Server.

Check also in this Manual Chapter 3.3
