Generate local data
You have the option of generating local data for all or for selected nodes of the server
interface that are not already assigned ("mapped") to local data of the CPU. The newly
created local data are mapped automatically.
You trigger the automatic generation of local data by clicking the "Generate local data"
button (all nodes that are not already mapped) or by selecting individual nodes and then
clicking the "Generate local data" shortcut menu.
"Generate local data" button:
Figure 9-41 "Generate local data" button:
You can only generate nodes that can be mapped to local data, which means no objects, no
folders, no methods or input/output arguments of methods.
After you have clicked the button or selected the shortcut menu, you must select in the
follow-up dialog box whether the local data should be created in a new DB or in an existing
DB.
Consistency check
You have the option to check the server interface.
During the consistency check, STEP 7 checks whether the OPC UA nodes of the server
interface are each assigned to a suitable OPC UA element (identical data type) or whether the
used element still exists in the CPU.
To check the consistency of the server interface, click on the following icon in the toolbar of
the OPC UA server interface editor:
Figure 9-42 "Consistency check" button

contains all data type definitions referenced by the server interface.
To export the OPC UA server interface, click on the following icon in the toolbar of the OPC
UA server interface editor:
