Consistency check and saving

Saving and consistency check
Once you have completed the parameter assignment in the hardware configuration, the
current version must be saved with the "Station / Save" menu. You can generate system
data blocks (SDBs) using the "Save and compile" menu later since there are still other
configuration steps necessary before the SDBs can be generated completely. When you
close hardware configuration, a dialog opens automatically prompting you to save your
entries.
When you select the "Save and compile..." function, a consistency check is run and a
message is displayed if configuration errors are detected.
