Limit number of
differences
The number entered here determines the number of differences that can
be found before the current comparison operation is aborted.
Show pre-
engineering changes
only for feeders and
switchgear objects
When this box is checked (default setting), the comparison is restricted to
determining whether changes have taken place in relation to the pre-
engineering data for bays and switchgear. Generally, the default settings
should be retained as otherwise the number of differences that will be
discovered increases considerably (events, signals etc., are then also
taken into account)
Write log file The results of the comparison are stored in a file.
