Selecting the charts
A dialog box displays all charts that can be selectively downloaded. Select the charts that
you want to download in this dialog box. Dependent charts are also automatically selected.
The charts that are not selected but affected by the changes are not transferred as well.
System charts with the prefix "@" are not displayed but are automatically transferred as well
if they are affected by the changes.
Note
Dependent charts arise due to one of the following conditions:
• Change to an SFC type: All charts that contain an instance of this SFC type are
dependent and are also downloaded when the SFC type is downloaded.
• A dependent chart is a chart that contains at least one block which is in the same runtime
group as a block of the chart to be downloaded.
Before downloading
Make sure that no dangerous system states can arise before downloading. If you have
changed multiple charts with cross-chart interconnections and do not then transfer all
charts to the AS together using "Selective downloading", damage could occur due to
inconsistent states.
Note
You can find additional information on the subject of "Selective download" in configuration
