7. Click "OK".
STEP 7 (TIA Portal) imports the information model described in the selected XML file.
An error occurs when type definitions are used in the imported XML file that are not yet
present in STEP 7 (TIA Portal) and that are also not contained in the imported XML file.
In the example, an XML file is imported that uses type definitions defined in the following
namespaces (Namespaces):
– http://opcfoundation.org/UA/DI/
– http://www.euromap.org/euromap83/
– http://www.euromap.org/euromap77/
Tip: STEP 7 displays missing namespaces in the lower area of the OPC UA interface
editor ("Properties" tab).
To do this, select the server interface in the project tree (here: IMM_Manufacturer_01234)
and select the "Namespaces" area in the inspector window. Missing namespaces are
selected.
If one or more namespaces are missing in your STEP 7 project, create a new server
interface of the "Reference namespace" type for each namespace.
The "Creating a server interface for reference namespace (Page 223)" section describes
the procedure.
If all reference namespaces are available, STEP 7 displays the table without errors:
8. Drag the OPC UA elements from the right area of the table (OPC UA elements) to the left
part of the table (OPC UA server interface) so that the respective OPC UA elements (the
local PLC tags) are assigned to the respective OPC UA nodes of Euromap 77.
