Limiting the view to OPC UA servers
By selecting the OPC UA elements, you limit the view to the OPC UA server and the options of
the OPC UA clients.
In the server interface of the example, the "Robot_1" data block is missing because industrial
trucks do not need access to the server methods and tags of the robot.
In this case, it is best to disable the standard server interface (SIMATIC namespace) in the OPC
UA properties of the S7-1500 CPU so that the filtered nodes cannot be accessed any other
way.
Figure 9-39 Disabling the standard server interface
You can also disable the visibility of each configured OPC UA server interface in the properties
of the server interface and thus prevent that this server interface can be used by clients
during operation.
•
To do this, select the server interface and right-click on the "Properties" command.
This option lets you define multiple server interfaces centrally, for example, and enable and
download only the required server interface.
Once a server interface has been defined, you can drag it to another CPU in the project tree.
