Rules for OPC UA XML files

Importing exported OPC UA XML files to an S7-1500 CPU
Please note the following information when importing server interfaces that come from the
OPC UA XML export of an S7-1500.
Note
Import blocked for namespace "http://www.siemens.com/simatic-s7-opcua"
You cannot import server interfaces with the namespace "http://www.siemens.com/simatic-
s7-opcua" to an S7-1500 CPU because this namespace is reserved for S7-1500 CPUs (standard
SIMATIC server interface) and is not available for imports.
If you want to import a server interface with the namespace
"http://www.siemens.com/simatic-s7-opcua", open the server interface to be imported (OPC
UA XML file) and change the namespace in the relevant places. The file thus changed can
then be imported.
