Effect on settings in the DB editor
If you hide a DB using the DB attribute described here, the settings for the components in
the DB editor are no longer relevant; individual components can no longer be accessed or
written.
Tip: Using the overview of all program blocks
If you are using multiple data blocks, it is appropriate to use the detailed overview of the
"Program blocks" folder for selective activation or deactivation of the OPC UA accessibility.
Follow these steps:
1. Select the "Program blocks" folder in the project tree.
2. Select the "Overview" command in the "View" menu.
3. Select the "Details" tab.
An overview of the blocks with their attributes is displayed.
4. Ensure that the "Data block accessible via OPC UA" column is selected.
5. Select only the data blocks that are to be accessible via OPC UA.
