OPC UA communication
9.3 Using the S7-1500 as an OPC UA server
Procedure in SiOME 1.7.3
Note
The following description shows the work steps in SiOME 1.7.3.
Follow-up versions of SiOME make it easier for you, for example, to create corresponding
DBs, structures, variables or methods in the user program. Using a drag-and-drop operation,
you can transfer data, for example, from SiOME to the TIA Portal (user program). In this case,
the variables, etc. are already mapped correctly or, for methods, the corresponding FB
elements are also generated correctly in the user program.
Download the current SiOME version using the download link listed above, and follow the
instructions in the documentation included in the download.
The following description shows the work steps in SiOME 1.7.3.
To use Euromap 77, create an XML file with an instance of "IMM_MES_InterfaceType".
The object type must be instantiated in order for the information model of the specific
machine to appear in the address space of the OPC UA server.
The object type "IMM_MES_InterfaceType" is the root object type of Euromap 77. "IMM"
stands for "Injection Moulding Machine".
Follow these steps:
1. Download the files "Opc_Ua.EUROMAP77.NodeSet2.xml" and
"Opc_Ua_EUROMAP83_NodeSet2.xml" from the Euromap website (see above).
2. Download the file "Opc.Ua.Di.NodeSet2.xml" from the OPC Foundation website.
The "Opc.Ua.Di.NodeSet2.xml" file contains type definitions which Euromap 77 uses.
3. Start SiOME.
4. First, import the namespace "http://opcfoundation.org/UA/DI/".
To do so, click the "Import XML" button in the "Information model" area.
Figure 9-27
SiOME displays the dialog for the opening files.
5. To import the file, select the "Opc.Ua.Di.NodeSet2.xml" file and click "Open".
Result: SiOME imports the XML file and shows the namespace
"http://opcfoundation.org/UA/DI/" in the "Namespaces" area.
The standard namespace "http://opfoundation.org/UA/" is always available in SiOME and
does not have to be imported.
6. Now import the namespace "http://www.euromap.org/euromap83/"
To do so, click the "Import XML" button again in the "Information model" area.
Select the file "Opc_Ua.EUROMAP83.NodeSet2.xml".
Result: SiOME imports the XML file and shows the namespace
"http://www.euromap.org/euromap83/" in the "Namespaces" area.
