Map aasx file to opcua #360

Open hadifar opened 1 week ago

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

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:
