each namespace.
Add additional server interfaces for Euromap77
For Euromap 77, you still need the following namespaces:
● http://www.euromap.org/euromap83/
● http://www.euromap.org/euromap77/
First, add a server interface for the namespace "http://www.euromap.org/euromap83/".
This namespace contains basic definitions for Euromap 77, therefore it is required here first.
All definitions of this namespace are included in the XML file
"Opc_Ua.EUROMAP83NodeSet2.xml", which you can download from the Euromap website
(www.euromap.org/en/euromap83).
Then add a server interface for the namespace "http://www.euromap.org/euromap77". All
definitions of this namespace are included in the XML file
"Opc_Ua.EUROMAP77.NodeSet2.xml", which you can also download from the Euromap
website (www.euromap.org/en/euromap77).
