Map aasx file to opcua

[hadifar]

Hi all,
Thanks for your valuable contribution.
I'm trying to map aasx to opcua like the following picture:

However, when I export nodeset2.xml from package-explorer and import it to the OPC UA server using the following script in Python, it gives me an exception. Do you know how to do that?

I would greatly appreciate it if you can help me with this.

import logging

from opcua import Server

logging.basicConfig(level=logging.INFO)
_logger = logging.getLogger('asyncua')


def main():
    server = Server()
    filename = "Opc_export.xml"
    server.import_xml(filename)
    server.start()

if __name__ == '__main__':
    main()

Exception:

INFO:opcua.common.xmlparser:Parsing node: ns=1;s=AssetAdminShell 1:AssetAdminShell

I also encountered this issue and solved it by taking the UAObject at the end of the xml, cut it and insert it at the top of the xml as the first defined UAObject. Also I had to add another reference to it, see example:

<UAObject NodeId="ns=1;s=AssetAdminShell" BrowseName="1:AssetAdminShell">
    <DisplayName Locale="en">AssetAdminShell</DisplayName>
    <References>
      <!-- Link AssetAdminShell to the standard Objects folder -->
      <Reference ReferenceType="i=35" IsForward="false">ns=0;i=85</Reference>

      <Reference ReferenceType="i=47">ns=1;i=86</Reference>
      <Reference ReferenceType="i=47">ns=1;i=92</Reference>
      <Reference ReferenceType="i=40">i=61</Reference>
    </References>
  </UAObject>

Only with these extra changes I could successfully run the exported nodeset.
