Changing OPCUA identifier type for mappView connection to external OPCUA server

Hi all,
I’m trying to bind mappView widgets to an external OPC UA server. The external server has been added, and according to the log file, the connection is successfully established.

However, I’m unable to read any nodes from the server. The server’s NodeIds use identifier type: numeric, but it seems that mappView always tries to access them using identifier type: string.

Is there a way to configure mappView to use the numeric identifier type when connecting to an external OPC UA server?

Browsing the same node using uaexpert looks like this:

I’ve already tried several variations in the binding file, such as:

  • refId="ns=2,i=6067"
  • refId="6067"
  • refId="i=6067"
  • refId="2,6067"

But none of them worked.
Is there a way to change the identifier type?
Any advice would be appreciated.
Thanks a lot,
Bernhard

Yes this is possible. See section Variables on a remote OPC UA server with namespace and identifier in the AS-Help(online)
