Functions
After pressing the button B15, the system checks whether all busbar
connectors are assigned to a bus zone. At the end of the test, a
message box indicates the test result.
In most cases, the bus zones are automatically assigned at the
moment the Bay Model is inserted into the single-line diagram. For
complex bus-configurations or after modifications on an existing
Setfile (re-configuration), a reassignment of the bus zones could be
necessary.
By pressing the button B16 the complete bus zone arrangement is
reassigned. The reassignment might be necessary if an existing setfile
has to be extended with new bay models and new bus zones are
generated.

If not all busbar connectors are assigned to a bus
zones, the correct function of the REB500 system
cannot be guaranteed.
If the bus zone reassignment process is started
with button B16, the configurator tool also
performs the reassignment of the bus zone related
signals (I/Os) in the background automatically. Re-
configuration of a complex system (setfile) can
induce a changed signal configuration in
comparison to the original setfile. If necessary,
these bus-zone related signals have to be worked
over under the binary module configuration of the
Central Unit (CU).
