Example Euromap 77 (currently OPC 40077)
You have added a server interface for the companion specification Euromap 77 (currently
OPC 40077).
The server interface uses object types defined in OPC UA DI as well as in Euromap 83 and
Euromap 77 in their corresponding namespaces.
Therefore, in addition to the server interface Euromap 77 of the "Companion Specification"
type, create additional server interfaces of "Reference namespace" type in STEP 7, in each
case for the following namespaces:
•
http://opcfoundation.org/UA/DI/
• http://www.euromap.org/euromap83/
• http://www.euromap.org/euromap77/
The following description shows you how to proceed.
Creating a server interface for a reference namespace
To create a server interface for a namespace, proceed as follows:
1.
Select the CPU that you want to use as an OPC UA server.
2. Click "OPC UA communication > Server interfaces".
3. Double-click "Add new server interface".
STEP 7 (TIA) now displays the dialog "Add new server interface".
A general name for the new server interface is entered in the dialog, for example
"Server_Interface_1".
4. Assign a descriptive name for the new server interface.
In the example, select the name "OPC.Ua.Di" or a similar name that clearly references the
namespace "http://opcfoundation.org/UA/DI/".
This namespace must be imported first. It contains basic definitions (for example, the
UAObjectType "DeviceType").
